WhatsApp Broadcast Messages — The Complete 2026 Guide to Bulk Messaging

WhatsApp Broadcast is the fastest, highest-engagement marketing and service channel you have. Open rates of 85–98%, reply rates 10–25× email, and click-throughs 3–6× SMS — when you do it right. This guide covers what a broadcast actually is (and isn't), the Business App vs API trade-off, Meta's template rules, opt-in law across DPDPA / PDPL / GDPR, a 6-step send workflow, industry benchmarks, and the quality-rating discipline that separates high-ROI senders from suspended numbers.

Published: 20 April 2026 Updated: 20 April 2026 Covers: Broadcast · Templates · Quality · Compliance Reading time: ~13 min

📌 TL;DR

A WhatsApp broadcast is a one-to-many outbound message sent to opted-in contacts through the WhatsApp Business API. On the free WhatsApp Business App, you're capped at 256 contacts per broadcast list and broadcasts go only to people who have your business saved in their phone contacts — so it's useless for any real marketing list. On the WhatsApp Business API (via a BSP like Go4whatsup), you can send to thousands of opted-in contacts using Meta-approved templates, with full segmentation, variables, media, and buttons. Templates must be pre-approved and fall into three categories — Marketing, Utility, Authentication — each with different compliance rules, pricing, and delivery behavior. Done right, broadcast opens hit 85–98%, CTR hits 15–45%, and a well-targeted retention broadcast earns ₹10–25 per ₹1 spent. Done wrong, quality rating tanks in a week and your number gets throttled or paused.

1. What a WhatsApp broadcast actually is

A WhatsApp broadcast is a single message sent simultaneously to many recipients — where each recipient sees it as a private, one-to-one conversation. It's not a group chat (nobody can see the other recipients), it's not a forward, and it's not a spam blast — every broadcast on the API must be a Meta-approved template sent to an opted-in contact.

There are three things a broadcast fundamentally is:

  • Outbound — initiated by the business, not a reply to a customer message (replies are handled by the free 24-hour session window).
  • Templated — the message body is pre-approved by Meta with defined variables; free-text broadcast is not permitted.
  • Private — each recipient gets the message in their own one-to-one thread with the business, with no visibility of other recipients.

A broadcast is how a business does the outbound half of WhatsApp. The inbound half (replies, FAQs, order tracking) is handled by a chatbot and a shared inbox. Together, they form the complete marketing + service loop.

Broadcast vs Group vs Label — what's the difference?

WhatsApp Broadcast (API)

  • Private 1-to-1 delivery to each contact
  • Unlimited list size (respecting messaging tier)
  • Meta-approved templates with variables
  • Opt-in required; receives delivery + read receipts
  • Full analytics: sent / delivered / read / clicked

WhatsApp Group / Label (Business App)

  • Group: recipients see each other — not private
  • Business App broadcast list: 256-contact cap
  • Recipient must have business saved in contacts
  • No templates, no variables, no analytics
  • Manual opt-in tracking; no compliance tooling

2. Business App vs API — the 256-contact ceiling

Most merchants start with the free WhatsApp Business App, try to send a broadcast to their customer base, and hit a brick wall. Here's why the Business App can't do real broadcast — and when you need the API.

Capability Business App (free) Business API (Go4whatsup)
List size per broadcast256 contacts maxUnlimited (within tier)
Recipient must have you savedYes — otherwise won't deliverNo — opt-in is sufficient
Templates & variablesNo — free text onlyYes — Meta-approved templates with {{1}}, {{2}}
Media (image / video / PDF)Yes, attached each time manuallyYes, via template header, auto-delivered
Buttons (URL, quick reply, call)NoYes — up to 10 buttons per template
Segmentation & schedulingNoYes — tag, segment, schedule, A/B test
Analytics (sent / read / clicked)Delivered / read ticks onlyFull funnel including click-through
CRM & e-commerce integrationNoneShopify, Odoo, Zoho, Salesforce, HubSpot
Typical costFree (but doesn't scale)From AED 0 Free Plan · AED 149/mo Standard

If your customer list is under 256 people and they all have your number saved, the Business App is fine. Beyond that — any real marketing list — you need the WhatsApp Business API through a BSP like Go4whatsup.

3. Marketing, Utility, Authentication — the 3 template categories

Every WhatsApp broadcast template must be classified under one of three Meta categories. The category determines when you can send, what content is allowed, and how much Meta charges per conversation.

🎯 Marketing

Use for: promotions, launches, offers, cart-recovery nudges, re-engagement, seasonal campaigns, newsletters.

  • Opt-in: explicit marketing opt-in required (checkbox, WhatsApp opt-in CTA, signed consent).
  • Pricing: highest per-conversation tier; regional (India ~₹0.78, UAE ~AED 0.12 per conversation).
  • Free window: if you reply to a customer-initiated message within 24 hours, no new conversation fee — but a pre-scheduled broadcast doesn't qualify.
  • Quality risk: highest — aggressive marketing is the #1 cause of quality-rating drops.

🛎 Utility

Use for: order confirmations, shipping updates, appointment reminders, fee receipts, renewal reminders — anything transactional that the user is expecting.

  • Opt-in: transactional opt-in is sufficient (e.g., placing an order implies consent for order updates).
  • Pricing: lower than Marketing; the first 1,000 service conversations per phone number per month are free (as of April 2026 Meta pricing).
  • Quality risk: low — users expect these messages.
  • Watch-out: Meta's 2024 classifier auto-reclassifies templates that are promotional in disguise. "Your order is ready — and here's 20% off your next one!" gets flagged as Marketing.

🔐 Authentication

Use for: OTPs, 2FA codes, login verification. Nothing else — Meta enforces this strictly.

  • Opt-in: implicit from the login attempt itself.
  • Pricing: cheapest per-conversation tier in most markets.
  • Format: must use the Authentication template scaffold with a Copy-Code button; plain-text OTPs outside the scaffold get rejected.
  • Use case: not a marketing channel — but critical for fintech, ed-tech, and any login-gated product.

For a full tour of Meta's template spec — variables, headers, footers, buttons, rejection reasons — see the WhatsApp Message Templates Library cornerstone, which includes 32 ready-to-use template examples across 8 industries.

4. Opt-in rules — DPDPA, PDPL, GDPR, Meta Business Policy

Every WhatsApp broadcast — without exception — requires opt-in from the recipient. "Everyone who bought from us before" is not an opt-in; "everyone who subscribed to our email newsletter" is not a WhatsApp opt-in. The consent must be specific to WhatsApp, informed, and recorded.

What a valid opt-in looks like

  • Checkbox at checkout or signup: "I agree to receive order updates and offers from [Brand] on WhatsApp." (Marketing consent should be an unchecked box by default in GDPR/DPDPA markets.)
  • WhatsApp-first opt-in: the user messages you "START" or "SUBSCRIBE" from a wa.me link, QR code, or website widget.
  • Keyword on a landing page: "Send us 'HI' on WhatsApp to get order updates" — the inbound message is the opt-in.
  • In-CRM record: consent captured during a support call, stored with timestamp, source, and the exact consent language shown.

Jurisdictional specifics

  • India (DPDPA 2023): explicit, affirmative, informed consent; maintain consent record with timestamp; honor withdrawal within a reasonable timeframe.
  • UAE / KSA (PDPL): consent must be freely given and documented; data subjects can withdraw at any time.
  • EU / UK (GDPR / UK GDPR): opt-in must be a clear affirmative act — pre-checked boxes are invalid; separate consent for marketing vs transactional.
  • Meta Business Policy (global floor): on top of local law, Meta requires opt-in evidence. Meta can audit your opt-in records during quality-rating investigations and will suspend numbers sending to un-opted contacts.

Go4whatsup captures opt-in metadata (source, timestamp, consent language, IP) on every contact and exports it on demand for DPDPA / PDPL / GDPR audits.

5. 6-step send workflow (from list to delivery)

Here's the end-to-end workflow for a production broadcast on Go4whatsup. The same six steps apply whether you're sending to 500 contacts or 500,000 — the ramp-up is just different (covered in §9).

  1. Step 1 — Prepare and clean the list. Export from your CRM / Shopify / Odoo / Google Sheet. Strip contacts without opt-in consent, contacts who opted out, and any number format errors. Include an opt-in source column so Meta can be shown evidence if asked. Go4whatsup imports CSV, XLSX, or native CRM sync — with auto-dedup on phone number. Tip: never buy a WhatsApp list. Purchased lists have zero consent, near-zero open rate, and will tank your quality rating within 72 hours of your first send.
  2. Step 2 — Segment. Split the list into audiences where the same message will land the same way. Typical segments: new customers (first 30 days), repeat customers, VIP (top 10% by spend), lapsed (90+ days inactive), language, country, last product category purchased. Specificity beats reach — a segmented 10K send usually outperforms a generic 50K send on revenue.
  3. Step 3 — Pick or draft the template. Either reuse an existing Meta-approved template or draft a new one in the Go4whatsup template editor (or validate with our free WhatsApp Template Generator). Submit for Meta approval — typical turnaround is minutes for Utility/Authentication, 1–4 hours for Marketing. Tip: always keep 2–3 approved Marketing templates "on ice" so you're never waiting on Meta review when a time-sensitive promo goes live.
  4. Step 4 — Personalize and A/B. Fill in the template variables ({{1}} = first name, {{2}} = order ID, etc.) from the segment's CRM fields. If the audience is >5,000, set up a 10% A/B test — two template variants with different headlines or offers. Pick the winner, roll out to the remaining 90%.
  5. Step 5 — Schedule (or send now). Pick a send time in the recipient's local timezone. For Marketing, 10 AM–8 PM local typically gets the best open rate; avoid late night and very early morning. Schedule batches rather than one giant send — Go4whatsup paces automatically to protect quality rating (see §9).
  6. Step 6 — Monitor and react. Watch the quality rating in real time on the Go4whatsup dashboard. If quality starts dropping, pause the send, investigate (usually opt-in hygiene or template content), and only resume when the rating stabilizes. Don't "push through" — a pause today saves a suspension tomorrow. Tip: the first 4 hours after send are where 80% of the open + reply activity happens. If CTR is tracking 40% below your usual baseline by hour 2, you've got a template problem — not a bad day.

6. Segmentation & personalization — the ROI multiplier

The difference between a broadcast that earns 3× ROAS and one that earns 15× ROAS is almost never the offer — it's the segmentation. A well-segmented list typically delivers 2–4× the CTR and 3–8× the conversion rate of a generic blast to the full database.

The four segmentation axes that matter most

  • Lifecycle stage: new (0–30 days), active repeat, lapsed (60–90 days), dormant (180+ days). Each needs a different offer and tone.
  • Purchase history: category last purchased, AOV tier (low / mid / high), total LTV. Drives product relevance and appropriate discount depth.
  • Geography + language: especially in India (Hindi/English/Tamil/Telugu/Marathi) and GCC (Arabic/English). Go4whatsup's auto-translation handles this across 100+ languages automatically.
  • Engagement: users who opened the last 3 broadcasts are worth 10× a dormant user for your next broadcast. Pull them into a priority segment.

Example: a retail brand's Diwali broadcast

A Jaipur-based apparel brand running a ₹25K Diwali campaign would typically split their 18,000-contact list like this: VIP repeat buyers (top 1,500) get early-access + bundled offer; active mid-tier (6,000) get the main 25% promo; language-Hindi regional (4,000) gets the same promo in Hindi via auto-translate; lapsed 90+ day (4,500) gets a win-back-only offer (30% off); dormant 180+ (2,000) gets a single "We miss you" nudge or is held out entirely to protect quality rating. Same budget, same product, five campaigns instead of one — and two to three times the revenue.

7. Benchmarks — open rate, CTR, CVR by channel and industry

These are industry-median ranges from Go4whatsup's customer base and publicly reported aggregates. Your mileage will vary; what matters is the order of magnitude — WhatsApp broadcast beats every other outbound channel on almost every metric that matters.

Channel comparison (like-for-like offer)

8. Quality rating — the three tiers and what triggers each

Meta continuously grades every business number on a quality rating derived from user feedback — blocks, reports, opt-outs, and low engagement. Your rating determines your messaging tier and, if it drops far enough, whether Meta pauses your number entirely.

🟢 High

Low block/report rate, strong opt-in hygiene, engaged list.

Effect: full messaging tier, no throttling, fastest tier upgrades (Tier 1 → 2 → 3 → 4 → Unlimited).

🟡 Medium

Some blocks, declining open rate, promotional saturation, borderline content.

Effect: Meta may delay a pending messaging-tier upgrade. Fix opt-in hygiene, reduce Marketing frequency, pause lapsed segments.

🔴 Low

Elevated block/report rate, mass opt-outs, spam flags.

Effect: number gets throttled (fewer sends/day), tier can be downgraded. If it stays Low across evaluation windows, Meta pauses the number — business-impact emergency.

Go4whatsup surfaces the live quality-rating tier on every dashboard view and sends proactive alerts when a sender slips from High to Medium, so you can act before it becomes a suspension.

9. Pacing, ramp-up, and messaging-limit tiers

Meta caps the number of unique recipients you can message per 24 hours based on your tier. A newly-verified number starts at Tier 1 (250/day) and progresses automatically as you demonstrate quality engagement.

Tier Unique recipients / 24h How to unlock
Tier 1250Default at verification
Tier 21,000Message 500 unique users in 7 days with High/Medium rating
Tier 310,000Message 1,000 unique users in 7 days with High/Medium rating
Tier 4100,000Message 10,000 unique users in 7 days with High/Medium rating
UnlimitedNo capMessage 100,000 unique users in 7 days with High/Medium rating

Practical ramp-up plan for a new number

  1. Week 1: warm up with Utility-only sends (order confirmations, appointment reminders) to your most engaged 500 contacts. Goal: lock in a High quality rating before any Marketing send.
  2. Week 2: first Marketing send to a small, highly engaged segment (500–1,000 contacts). Keep opt-out language in footer. Monitor block/report rates daily.
  3. Week 3: if quality is still High, expand to 2,000–5,000 contacts per send. Add segmentation so each sub-segment sees relevant content.
  4. Week 4+: full-scale sends to the core segments; tier-upgrade requests auto-process in the background.

Skipping this ramp — trying to send a Marketing broadcast to 20,000 contacts on day one — is the most common way a new number gets throttled before it's ever earned any revenue.

10. The 4-nudge retention sequence (cart, re-order, win-back)

The highest-ROI broadcasts are not one-off blasts — they're short, scheduled nudge sequences triggered by customer behavior. Here's the canonical 4-nudge pattern that most Go4whatsup customers run.

🛒 Nudge 1 +30 min — cart reminder with item image
💬 Nudge 2 +4 hr — social proof + CTA
🎁 Nudge 3 +24 hr — soft 10% incentive
Nudge 4 +68 hr — last call, limited stock

All four nudges fit inside the 72-hour CTWA free-marketing window if the customer originally landed via a Click-to-WhatsApp ad — meaning zero marginal Meta fee on the recovery. This is the entire economic unlock behind running cart recovery on WhatsApp vs email. See the Click-to-WhatsApp Ads cornerstone for the free-window mechanics.

Example nudge 1 (cart reminder)

Hi Priya, noticed you left a few items in your cart 🛒

Linen Midi Dress · ₹3,499
Cotton Kurta Set · ₹2,199

Tap below to complete your order — we'll ship today. Complete Checkout → Utility · Shipped by Go4whatsup · Opt-out: reply STOP

Other high-ROI nudge sequences

  • Re-order nudge (60/90/180 days): for replenishment-cycle products — supplements, pet food, beauty. Conversion rate often 3–8× a cold Marketing blast.
  • Win-back (90-day lapsed): single-message "we miss you" with a narrow, time-limited offer. Avoid multi-nudge on lapsed — it's the fastest way to rack up opt-outs.
  • Post-purchase upsell (day 7 and 30): cross-sell complementary products based on last purchase category.
  • Loyalty milestone: "you've unlocked VIP status" style broadcasts to the top 10% LTV tier.

11. AI for broadcasts — campaign copy and language detection

Go4whatsup ships four AI capabilities today, and two are directly load-bearing for broadcast workflows. Honest framing: these augment the marketer, they don't replace judgment.

What AI does for broadcasts

  • AI-generated campaign copy: describe the offer, audience, and tone — AI drafts three template variants (headline, body, CTA) ready for Meta submission. Typical copy draft: 60 seconds instead of 20 minutes. Marketer still reviews and picks the winner.
  • AI-powered language detection: on inbound replies, detects the customer's language across 100+ languages and triggers auto-translation for the agent. Critical for GCC (Arabic/English) and Indian regional (Hindi/Tamil/Telugu/Marathi/Bengali) markets.
  • AI auto-reply: handles the predictable 60–80% of replies to your broadcast (product questions, delivery timing, return policy) without waking an agent.
  • AI-drafted replies: suggests a reply for an agent to edit and send — especially useful for high-volume broadcast response windows.

What AI does NOT do — and shouldn't

  • AI does not auto-send broadcasts — a human always approves the recipient list, template, and schedule.
  • AI does not decide opt-in status — consent is a hard rule with a hard record, not a probability.
  • AI does not make binding promises on price, availability, or delivery timing in inbound replies — it defers to data-layer lookups or hands off to a human.
  • AI does not optimize for Marketing category aggression — if a campaign is too promotional, the product tells the marketer, not the other way around.

12. 7 mistakes that tank quality rating

❌ Sending to a purchased list.
Fix: build your list from your own sources (checkout opt-in, wa.me replies, website widget, QR on packaging). A 2,000-contact opt-in list beats a 50,000 purchased one on revenue and does not threaten your number.
❌ Classifying Marketing as Utility to get lower fees.
Fix: Meta's 2024 category classifier auto-detects promotional content in Utility templates and re-classifies them — plus damages quality rating. If it's promotional, submit it as Marketing from the start.
❌ Broadcasting too frequently to the same segment.
Fix: cap Marketing frequency at 2–4 sends per contact per month for active segments. Lapsed segments: one send per 30 days max. Every extra send past the cap drags down opt-in-to-opt-out ratio.
❌ Skipping the opt-out mechanism.
Fix: every Marketing broadcast must include opt-out language — "reply STOP to unsubscribe" in the footer or an explicit opt-out quick-reply button. Go4whatsup auto-processes STOP replies into unsubscribe with a confirmation message.
❌ Firing the first broadcast at full list size on day one.
Fix: follow the ramp plan in §9 — Tier 1 is 250/day, Tier 2 is 1,000/day, and jumping straight to 10K sends before your quality rating is locked at High is how numbers get paused.
❌ No segmentation — same message to the full database.
Fix: at minimum, split by lifecycle (new / active / lapsed / dormant) and language. Generic blasts get 3–5× the opt-out rate of segmented sends.
❌ Ignoring the quality-rating dashboard until it's Low.
Fix: watch the tier daily in the Go4whatsup dashboard. The moment it moves from High to Medium, pause new Marketing sends and investigate — opt-in hygiene, template content, frequency. Fixing at Medium is a day's work; fixing at Low is a business-impact incident.

13. How Go4whatsup runs broadcasts for customers

Go4whatsup's broadcast stack ships on the Standard plan (AED 149/mo) and up, with AI campaign copy + auto-reply on PRO (AED 499/mo). Typical customer setup takes 1–2 business days from verified Meta Business Manager to first broadcast live.

  • List management: CSV / XLSX / native CRM sync (Shopify, Odoo, Zoho, HubSpot, Salesforce, Google Sheets). Auto-dedup, opt-in metadata, one-click opt-out.
  • Template studio: drag-and-drop template builder with live WhatsApp chat-bubble preview, 17-point compliance scan before Meta submission, status tracking on pending / approved / rejected templates. Companion to our free Template Generator.
  • Segmentation: rule builder across any CRM field + behavior (last opened, last clicked, last purchased category). Real-time segment size counter.
  • Scheduling: local-timezone per contact, auto-pacing to protect quality rating, A/B testing at 10/90 split with auto-winner rollout.
  • Analytics: sent / delivered / read / clicked / replied / opted-out / converted — per template, per segment, per campaign.
  • Quality monitoring: live tier display, drop alerts, and template-level content flags.
  • AI assist: campaign-copy drafting, inbound auto-reply for FAQ-shaped replies, drafted-reply copilot for agents handling the high-volume reply spike that follows a big broadcast.
  • Native integrations: bi-directional Shopify / Odoo / Zoho / Salesforce / HubSpot sync, so every broadcast-driven reply auto-logs against the customer record.

Enterprise customers in GCC / India / Europe run multi-country broadcasts with auto-translation across Arabic, Hindi, Tamil, German, Spanish, French, and 100+ other languages — the same template sent in each recipient's preferred language from a single campaign configuration.

14. Frequently asked questions

Can I send WhatsApp broadcasts from the free WhatsApp Business App?

Technically yes — but with two hard limits that make it unusable for real marketing: each broadcast list is capped at 256 contacts, and the message only delivers to contacts who have your business number saved in their phone. For any list bigger than a few hundred, you need the WhatsApp Business API through a BSP like Go4whatsup.

What's the difference between a WhatsApp broadcast and a WhatsApp group?

In a broadcast, every recipient gets the message as a private one-to-one chat — they can't see each other. In a group, every member sees every other member's name and replies. Broadcast is the right format for marketing; groups are for community / customer-service squads at small scale.

How much does one WhatsApp broadcast cost?

Cost is per-conversation, not per message, and varies by country and category. India Marketing is ~₹0.78 per conversation; UAE is ~AED 0.12; EU ~€0.07–0.15. Utility is 25–40% cheaper; Authentication is cheaper still. The first 1,000 Service conversations per number per month are free. Use our free Cost Calculator to model your actual bill in local currency.

Do I need opt-in for every single contact on my broadcast list?

Yes. There is no legal or Meta-policy exception — even for customers who have bought from you before. Opt-in must be specific to WhatsApp, informed, and recorded. Go4whatsup stores opt-in source + timestamp per contact and exports the audit trail on demand.

How many broadcasts per day can I send?

Capped by your messaging-limit tier — starts at 250 unique recipients per 24 hours at Tier 1 and scales to unlimited as you demonstrate consistent High-quality sending. Each tier takes roughly a week of engaged sending to unlock; see §9 for the ramp plan.

Can I send promotional broadcasts at any time of day?

Meta doesn't restrict send times explicitly, but quality rating penalizes sends that users dismiss or block — late-night and very-early-morning sends get dramatically higher block rates. Best practice: send Marketing between 10 AM and 8 PM in the recipient's local timezone. Utility messages (order shipped, appointment reminder) can go any time because the user is expecting them.

What happens if my quality rating drops to Low?

Meta throttles the daily volume your number can send, and if the rating stays Low across evaluation windows, the number is paused. Recovery requires fixing the root cause (opt-in hygiene, template content, send frequency) and then sending a small volume of high-quality messages to rebuild the signal — typically 1–2 weeks.

Can I personalize broadcasts with the customer's name and order details?

Yes — Meta templates support variables ({{1}}, {{2}}, etc.) in the body and header. Go4whatsup fills these from your CRM fields at send time. Personalized broadcasts typically lift CTR by 15–30% over generic versions.

Can I include images, videos, or PDFs in a broadcast?

Yes — via the template header. Meta supports image, video, and document headers; you upload one at template-approval time (or pass a dynamic URL per send for catalog-style broadcasts). Image headers typically lift CTR by 10–25% over text-only.

How do A/B tests work on WhatsApp broadcasts?

On Go4whatsup, you can split a segment at 10/90 (or any ratio) between two approved templates, run the 10% early, pick the winner on the metric you care about (CTR or reply rate), and auto-roll out the winning variant to the remaining 90%. For segments under 5,000, A/B isn't statistically meaningful — just pick the stronger template and send.

What languages can I broadcast in?

Any language Meta supports at the template level — which includes Arabic, Hindi, Tamil, Telugu, Marathi, Bengali, Gujarati, Kannada, English, German, French, Spanish, Italian, Dutch, Portuguese, and 60+ others. Go4whatsup's auto-translation layer can additionally translate inbound replies across 100+ languages so your agent only ever sees one working language.

Can I schedule a broadcast for a future date and time?

Yes — on Go4whatsup, schedule by absolute UTC or per-contact local timezone. Local-timezone scheduling is the right default for international lists; it sends at, say, 6 PM local whether the recipient is in Delhi, Dubai, or Dublin.

What should I do if a customer replies to my broadcast?

Reply inside 24 hours and it's free (the customer-initiated session window). Replies are routed to your shared inbox on Go4whatsup, with AI auto-reply handling FAQ-shaped questions and drafted-reply suggestions speeding up agent responses. For a deeper tour of the always-on conversation side, see the WhatsApp Chatbot cornerstone.

Is broadcasting on WhatsApp GDPR / DPDPA / PDPL compliant?

Yes, if done correctly. Opt-in must be explicit, informed, specific to WhatsApp, and recorded. Every Marketing broadcast must include an opt-out mechanism (e.g., reply STOP). Data processing must be covered by a data-processing agreement with your BSP. Go4whatsup signs DPAs for EU/UK customers, maintains an EU sub-processor list, and is DPDPA- and PDPL-ready.

How fast can I go live with WhatsApp broadcast on Go4whatsup?

From a verified Meta Business Manager, typical go-live is 1–2 business days: Day 1 — WABA setup, phone verification, first 3 templates submitted for Meta approval. Day 2 — approved templates, list import, first small-scale broadcast (500–1,000 contacts). Day 3+ — ramp-up per §9. If you don't yet have Meta Business Manager, add another 2–3 days for verification; see the WhatsApp Business API Onboarding guide.
