Why every LetsBot send goes through the official WhatsApp Business API

LetsBot is an official Meta Business Partner. Unofficial bulk messaging risks a permanent Meta-level number ban — the moment Meta's automation flags it, your customer list and the trust you spent years building disappear. We make the harder choice: every send routes through the official channel, even when setup is a little slower.

Frequently asked questions about WhatsApp bulk messaging

What's the difference between LetsBot Bulk Messaging and other mass-sender tools?

LetsBot uses the official Meta WhatsApp Business API — not cracked Web/Mobile clients like grey-market mass senders, which get banned within days. Every campaign goes through Meta's quality review, ships from an approved template, and is smart-throttled across batches to protect your number's long-term quality rating.

How many bulk messages can I send per month?

It depends on your Meta tier + your plan cap. Tier 1: 250 recipients/day. Tier 2: 1,000. Tier 3: 10,000. Tier 4: 100,000. Tier Unlimited: open. LetsBot helps you climb tiers automatically by enforcing message quality and intelligent send distribution — most customers reach Tier 4 within 30-60 days.

Can I send marketing messages without official templates?

No — marketing messages on the official WhatsApp API must use Meta-approved marketing templates (review usually 24 hours). Service / utility / transactional messages can ship via utility templates without prior approval. LetsBot ships ready-made templates + suggests wording that's more likely to be approved.

Do you support audience targeting before sending?

Yes. Target by tags, plan tier, last-purchase date, engagement flag, or CSV upload with advanced filters. Customers who replied "unsubscribe" are auto-excluded — LetsBot keeps a central opt-out list that respects the Saudi regulation and WhatsApp policy.

How do you track bulk-campaign success?

Every campaign emits a live report: sent, delivered, read, replied, unsubscribed. We compute CTR + conversion (when a UTM link ships). Reports export to CSV and integrate with Google Analytics.

Can I send images and attachments in bulk campaigns?

Yes. Every template supports a header image / video / document. Images must be < 5 MB, video < 16 MB, PDF < 100 MB. LetsBot picks the right multimedia template automatically based on your message content — image templates get 3× the engagement of text-only.
