WhatsApp Broadcast Guidelines: Safe Limits & Best Practices
Sending broadcasts to a lot of people is where most WhatsApp accounts get into trouble. Send too much, too fast, or to people who never opted in, and your quality rating drops, your number gets flagged, and your daily limit shrinks — or the number is banned.
This page is a practical playbook: how many messages are safe to send, how often you should broadcast, and the habits that keep your number healthy. It applies to the WhatsApp Cloud API used by TailorTalk.
The one rule that matters most: only message people who opted in. A phone number in your database is not an opt-in — the person must have actively agreed to hear from you. Broadcasting to scraped or purchased lists is the fastest way to get banned.
How many can I safely send per day?
Your hard ceiling is set by your messaging tier — the number of unique people you can start a conversation with in a rolling 24-hour window:
| Tier | Unique customers / 24h | How you get there |
|---|---|---|
| Unverified (start) | 250 | New number, business not yet verified |
| Tier 1 | 1,000 | Complete Meta business verification |
| Tier 2 | 10,000 | Good quality + consistent volume |
| Tier 3 | 100,000 | Good quality + consistent volume |
| Tier 4 | Unlimited | Good quality + consistent volume |
Meta upgrades you automatically. It checks roughly every 6 hours whether you qualify, and moves you up when you have used at least ~50% of your current limit in the last 7 days and your quality rating is Medium or High. A verified business can move up fast — potentially jumping tiers within a single day.
The catch: the tier is your technical ceiling, not your safe volume. Blasting your full limit to a cold list on day one is exactly what triggers blocks and downgrades. Treat the tier as the maximum, and warm up to it.
Warm up a new number (don't send 1,000 on day one)
A brand-new number with no sending history looks suspicious if it suddenly broadcasts to thousands. Ramp up gradually so WhatsApp learns your traffic is wanted:
| When | What to send | To whom |
|---|---|---|
| Days 1–2 | Utility messages only (order updates, reminders) | Your most engaged ~500 contacts, then another ~500 |
| Days 3–7 | Add light marketing | Increase unique recipients gradually, watching engagement |
| Week 2+ | Normal broadcasts | Expand as quality stays Green/Yellow |
Rules of thumb while warming up:
- Start with people who recently talked to you — they're least likely to block.
- Lead with Utility templates; they get blocked far less than pure Marketing. See Template Messages.
- After each send, check delivery and quality before increasing volume. If quality dips, hold or reduce — don't push higher.
How often should you broadcast?
Frequency is the second most common cause of blocks. Aggregated across industry benchmarks, safe cadence looks like:
| Audience | Recommended frequency |
|---|---|
| Active / engaged contacts | 2–4 marketing messages per month (≈1–2 per week max) |
| Lapsed / inactive contacts | ~1 message per 30 days |
| Whole account | ~4–8 marketing broadcasts per month total |
Sending 3+ promotional messages per week to the same people reliably pushes block rates up. When in doubt, send less but more relevant.
Meta's own frequency cap
Independent of your tier, Meta enforces a per-user cap on Marketing templates — roughly 2 marketing templates per person per day across all businesses combined. If a recipient has already hit their cap, your marketing message simply won't be delivered, even if you're well under your daily limit. Utility and Authentication messages are not affected.
Keep your block & report rate low
WhatsApp watches how people react. The ratio matters more than raw numbers:
- Keep blocks + spam reports under ~2–3% of recipients per send. Cross that and your quality rating starts dropping.
- A Low (Red) rating can get your number Flagged; if it doesn't recover within ~7 days, Meta can downgrade your tier (e.g. 10K → 1K) or restrict the number.

Healthy engagement benchmarks
For a warm, well-segmented list, aim for:
- Delivery rate: above 90%
- Read rate: above 70%
- Reply rate: 15–30%
If you're far below these, your list quality or targeting — not the send volume — is usually the problem.
Content & list habits that protect your number
- Opt-in only. Collect consent via website forms, QR codes, checkout, and in-store. No purchased lists.
- Segment before you send. Never blast one identical message to your whole list — tailor by engagement and interest.
- Personalize. At minimum use the recipient's first name; relevant messages get blocked far less. Use template variables.
- Prefer Utility over Marketing wherever the message qualifies — cheaper and safer.
- Make opting out easy and honor it immediately. One annoyed block hurts more than one lost contact.
- Time it well. Send during reasonable local hours, not late night.
- Clean your list. Drop numbers that repeatedly bounce or never engage.
Pre-broadcast checklist
Before you hit send on a large broadcast:
- Everyone on the list opted in
- List is segmented and the message is relevant to it
- Using an approved template (Utility if possible)
- Message is personalized (name / order details)
- Send size is within a safe ramp of recent volume (not a sudden spike)
- Current quality rating is Green or Yellow
- Frequency respects the cadence above (not spamming the same people)
- There's a clear opt-out
Frequently asked questions
What's a safe number of messages to send per day? Stay within your messaging tier and warm up to it — start around 500 engaged contacts/day on a new number and increase gradually. The tier (250 → 1K → 10K → …) is your ceiling, not your day-one target.
How often can I broadcast to the same person? For active contacts, 2–4 marketing messages per month (about one to two a week at most). More than three promotional messages a week noticeably raises block rates.
Can I send to 1,000 people every day? Yes, once your number is verified and on the 1K tier — but warm up to it rather than sending 1,000 on the first day, and keep block rates under ~2–3%.
What block rate is too high? Roughly 2–3%+ of recipients blocking or reporting a send will start dropping your quality rating. Sustained Low quality can downgrade your tier or get the number restricted.
Do I really need opt-in? Yes. Messaging people who didn't consent is the single biggest cause of blocks, low quality, and bans. A number in a spreadsheet is not consent.
