Official API The compliant way to send WhatsApp messages in bulk

Bulk WhatsApp messaging that doesn't get your number banned

Chrome-extension senders and “WhatsApp blast” scripts automate the consumer app, break Meta's terms and get numbers banned within days. Recoverly sends bulk WhatsApp messages the official way: opted-in audiences, Meta-approved templates, paced delivery through the WhatsApp Business Platform, and read and reply analytics for every send.

What a bulk WhatsApp message sender actually is (and which kind gets you banned)

A bulk WhatsApp message sender is any tool that delivers one message to many people. There are two very different kinds. The first automates the WhatsApp or WhatsApp Business app on your phone or in a browser: Chrome extensions, “WhatsApp blast” desktop software, Excel-to-WhatsApp scripts, modded apps. They work for a few days, then Meta's spam detection bans the number, often permanently, along with every contact and chat on it. WhatsApp's terms explicitly prohibit automated or bulk messaging through the apps.

The second kind sends through the WhatsApp Business Platform, Meta's official API. Messages go out as templates Meta has approved, to people who opted in, at a rate that respects your number's messaging tier and quality rating. There is no recipient cap, delivery and read receipts come straight from Meta, and your number is safe. That is what Recoverly does, and it is the only kind of bulk WhatsApp messaging worth building a business on.

The rest of this page explains how compliant bulk sending works, what it costs, how many messages you can send, and how to set it up in an afternoon.

Official API vs bulk sender tools
  • Your number stays safe. Sends go through Meta's platform, never through the app.
  • Anyone can receive. Recipients don't need to save your number, unlike app broadcast lists.
  • Real analytics. Delivered, read, replied and revenue per campaign, from Meta receipts.
  • Buttons and links. Quick replies and URL buttons on every message.
  • Consent enforced. Audiences are intersected with your opted-in list; STOP works instantly.
  • Pacing built in. Sends are throttled to your tier and paused if quality drops.
How it works

Bulk sending, done properly

Four things separate a campaign that sells from a blast that gets reported: who receives it, what it says, how fast it goes out, and what you learn afterwards.

Audiences

Send to the people who asked to hear from you

Every bulk send starts from your opted-in list. Build audiences from purchase history, tags, signup source, country and activity, then Recoverly intersects the audience with consent status so nobody who didn't opt in gets a message.

  • Smart segments. Everyone opted in, recent customers (30–365 days), repeat buyers, or abandoned checkouts.
  • Sync. Contacts and consent status sync from Shopify, Klaviyo or your CRM via Zapier and webhooks. CSV import is on the roadmap.
  • Suppression. Opt-outs, bounced numbers and quality complaints are suppressed automatically and permanently.

Templates

Messages Meta has already approved

Business-initiated bulk messages must use templates that Meta reviews. Recoverly ships proven marketing templates in 8 languages, lets you edit copy and variables, adds buttons, and submits the template for approval inside the app. Marketing templates are usually approved within hours.

  • Personalization. {{name}}, {{last_product}}, {{discount_code}}, {{city}} and any custom field.
  • Buttons. Quick replies for one-tap answers and URL buttons that deep-link to a product or booking page.
  • Media. Image, video or PDF headers for launches and catalogs.
  • Approval tracking. Status per template, rejection reasons explained, resubmission in one click.

Pacing & limits

How many bulk messages you can send

Meta sets a messaging limit per business portfolio: the number of unique people you can start conversations with in a rolling 24 hours. New businesses start low and move up automatically as they send quality messages at volume. Recoverly paces every campaign to your tier, staggers delivery and pauses if your quality rating drops, so a big send never burns the number.

  • Limits grow automatically. Meta raises the limit (250, then 2,000, 10,000, 100,000, unlimited) when you send consistently with good quality; verified businesses start higher.
  • Quality-aware sending. Block and report rates are watched; sending pauses at a red rating so you can fix the audience or copy.
  • Schedule and stagger. Send now or at a chosen time in your timezone; large sends are spread to protect deliverability.
  • No caps from us. Recoverly never limits recipients or messages on any plan.

Know what every send earned

Delivered, read and replied come from Meta's receipts, not estimates. Orders and bookings placed after a campaign are attributed to it, so you can compare a 20% discount blast with a plain launch announcement in real money.

  • Per-campaign dashboard. Recipients, delivered, read, replied, clicked, revenue and cost.
  • Replies in the inbox. Every answer lands in the shared inbox where AI or your team responds.
  • Export. CSV export of results and subscribers, included in Lite.

How it works

Your first compliant bulk send this afternoon

01

Connect your number

Continue with Meta, confirm your WhatsApp Business number, keep the phone app in coexistence mode. About two minutes.

02

Sync contacts and consent

Contacts and opt-in status sync from Shopify, Klaviyo or your CRM via Zapier and webhooks; the storefront widget and popup capture new opt-ins. Opt-outs are suppressed automatically.

03

Pick a template and send

Choose a marketing template, personalize it, build the audience, schedule. Watch reads, replies and orders arrive in the dashboard.

FAQ

Good questions

Yes, through the WhatsApp Business Platform with recipient opt-in, Meta-approved templates and a working opt-out. It is not allowed through the consumer or Business app: WhatsApp's terms prohibit automated or bulk messaging with the apps, and Meta bans numbers that do it. Local laws (GDPR, TCPA and similar) also require consent for marketing messages.
Use the official API, message only people who opted in, send approved templates, keep frequency reasonable (one or two marketing messages a month per contact is typical), honor STOP instantly, and pace large sends. Recoverly does the last four automatically.
Meta sets a messaging limit per business portfolio for business-initiated conversations in a rolling 24 hours: 250 for a new, unverified business, then 2,000, 10,000, 100,000 and unlimited as you send quality messages at volume. Replies to customers who message you are not counted. Recoverly shows your current limit and paces campaigns to it.
No. Template messages through the API reach anyone who opted in, whether or not your number is in their contacts. App broadcast lists only reach people who saved your number, which is the main reason they underperform.
Not by uploading a spreadsheet yet: contacts reach Recoverly from Shopify, Klaviyo, your CRM (via Zapier or webhooks) and the opt-in widgets, and CSV import is on the roadmap. Sending directly from Excel with a script or extension automates the app and risks a ban.
Recoverly campaigns are included in the Lite plan at $19/month with no recipient caps. Meta charges a per-message fee for marketing templates that varies by country (roughly one US cent in India, a few cents in the US and Europe); see the pricing guide. For replies, the first 1,000 replies inside the 24-hour customer window each month are free and the rest cost Meta's utility rate (from October 1, 2026).
Free extensions and “pro sender” scripts exist, and they are the fastest way to lose your number. Recoverly's free plan includes the chat widget so you can start conversations; sending campaigns needs the Lite plan at $19/month.
As of September 2026, Meta is not delivering marketing template messages to phone numbers with the United States country code (a pause Meta announced in 2025); utility, authentication and service messages to US numbers are unaffected, and marketing messages to every other country work normally.
