Features
Powerful Bulk Messaging Features
Everything you need to manage professional WhatsApp marketing campaigns
Smart Scheduling
Schedule your campaigns with precise timing control between messages. Automatic sending at the optimal time you choose.
All Message Types
Send text, images, videos, documents, and voice messages. Full support for all WhatsApp message types.
Campaign Analytics
Track campaign performance in real-time. Know how many messages were sent, delivered, and read.
Compliance & Safety
Built-in safety controls with smart timing between messages to protect your account and ensure full compliance.
Template Variables
Personalize messages with dynamic variables like customer name, order number, and more for higher engagement.
Recurring campaigns
Daily, weekly on the days you choose, or monthly on a day from 1 to 31 — with its own send time and timezone, and an optional end date, up to 1,000 runs. Add a monthly message cap and a per-contact frequency cap of 0–365 days. Every run sends paid marketing messages billed by Meta.
A/B testing
Test 2 to 4 variants on a test group of 5–50% of the audience (20% by default) for 1–72 hours (4 by default). The winner — by read, reply or click rate (read by default) — is sent to the rest automatically, or you pick it yourself. Template variants need an approved template on an official API number; plain-text variants work on any WhatsApp number, QR included.
Retargeting
Follow up with contacts who got the message but did not read it, read it but did not reply, replied, clicked, or did not click. Click rules apply only to Campaigns Pro sources, and “read” depends on the customer’s read receipts.
Per-contact link click tracking
Every link in a campaign is tracked per contact — on by default — so you know who clicked and who did not, and can build the follow-up on it.
Cost estimate before activation
Before you activate, see recipients × runs in the next 30 days, Meta’s fee by country and the next 5 send times. It is an estimate, in USD.
Where to find Campaigns Pro
Marketing → Bulk sending & campaigns → Campaigns Pro. It requires the Send Bulk add-on and is not available during the trial. Template header media can be picked from the media library (JPEG, PNG, MP4 or PDF, up to 16 MB).
How it works
From an Excel file to a delivery report
A campaign is built on one screen in the dashboard: the audience, then the message, then the schedule. After sending, you follow every message’s status on the campaign page.
Start Free TrialYour campaign in four steps
-
Import your contacts
Upload an Excel file with your customers’ numbers and organise them into groups and labels.
-
Pick the audience
Choose a group or one or more labels; the panel shows the real, de-duplicated recipient count before you send.
-
Build the message
Text, media or buttons — or an approved WhatsApp template whose variables map to contact fields such as the name.
-
Send now or schedule
Then follow the delivery stats, and export the contacts the message has not reached yet to an Excel file.

Platform trust
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.
LetsBot — official sending
- Officially listed by Meta as a Business Solution Provider
- Number protected against mass-flag bans by WhatsApp Business API
- Meta-approved message templates
- Rich media support: images, video, PDF, CTA buttons
- Green-tick verification possible for eligible accounts
- Direct Meta support + full policy compliance
Unofficial bulk (other tools in market)
- Permanent Meta-level number ban at any moment
- No approved templates — lower deliverability, higher spam classification
- Hard caps on media types and daily message volume
- No official Meta support when issues arise
- Direct WhatsApp ToS violation — potential legal exposure
- Customer-data loss the moment the ban hits, no recovery
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.
What is the best platform for WhatsApp bulk messaging in 2026?
Choose a platform that sends through the official WhatsApp Business API with Meta-approved templates to protect your number, shows a cost estimate before sending, and supports scheduling, recurring campaigns, A/B tests and click tracking. In LetsBot bulk campaigns need the Send Bulk add-on (+$24.99 a month, not part of the free trial), and every marketing message is billed at Meta's rate with no markup.
