How many WhatsApp messages can I broadcast a day?

Meta sets a messaging limit per phone number, not per account. A new number starts at 250 business-initiated conversations in a rolling 24 hours and steps up through 1,000, 10,000 and 100,000 to unlimited as your quality rating holds and volume proves out. The limit rises automatically; it also falls automatically if blocks and reports climb, and a number can be restricted outright. That is why throughput and quality are the same problem: a 60,000-message send that draws blocks in its first 5,000 costs you the tier you spent months earning.

Send big without getting blocked

Four-step wizard

Details, audience, template and variable mapping, then send or schedule — with a live cost estimate before you commit.

Pre-flight checks

Opt-in coverage, variable completeness, duplicate numbers and category mismatch flagged before the first message leaves.

Throttled ramp

Sends ramp instead of spiking, so blocks and reports surface early and you can stop mid-flight.

Quality circuit breaker

If block rate crosses your threshold, the campaign pauses itself and alerts the owner.

Segment-level testing

Split a template across two variants on 5% of the list, then push the winner to the rest.

Cost per outcome

Spend, delivered, read, clicks and attributed revenue on one screen — per campaign and per template.

How many messages can I send a day?

Meta sets the limit per number: new numbers start at 250 conversations a day and step up through 1K, 10K, 100K and unlimited as quality holds. We show your current tier and what triggers the next step.

Do I need opt-in for every recipient?

Yes for marketing. Under the DPDP Act and Meta’s policy you need demonstrable consent; sendlz stores the opt-in source and timestamp per contact and blocks sends to contacts without one.
