Bulk Messaging Done Right: Avoiding Spam & Maximizing Delivery

Support TeamRule number one: only message opted-in contacts
Before anything else: only message people who have agreed to hear from you. It is both a legal expectation and the single best way to keep your WhatsApp number safe from restrictions and bans.
List hygiene
- Remove unsubscribed contacts immediately
- Keep phone numbers clean and valid
- Segment by engagement — recently active customers convert far better
Content best practices
- Personalise with at least the customer's name
- Keep messages short and focused
- One clear call-to-action per message
- Always include an easy way to opt out
Timing
- Mid-week, mid-day in the customer's local time generally performs best
- Avoid public holidays and odd hours
- Use WaSMS scheduling to send at the right moment
Warm up new numbers
A brand-new WhatsApp number should not blast thousands of messages on day one. Start with smaller batches and increase volume gradually. Replying to people who message back keeps your number looking healthy to WhatsApp.
Monitor
Watch your delivery rate and your opt-out rate. If opt-outs start rising, pause and review your content and the quality of your list.
