List hygiene first
Validate that numbers are on WhatsApp before sending
Remove duplicates and malformed entries
Segment by interest or stage so messages stay relevant
Keep a suppression list of opt-outs
Write messages people welcome
Lead with value, not a hard sell. Keep the first message short, personal and clear, with a single call to action. Personalize with the recipient’s name and context, and vary wording with spintax so it never reads like a template.
Timing and pace
Send during reasonable local hours for the recipient
Use delays and smaller batches instead of one big burst
Spread large campaigns across a longer window
Watch replies and delivery; slow down if anything looks off
Measure and improve
Track what gets replies, not just what gets delivered. Test different first lines, offers and send times on small segments before scaling. Over time, a smaller, well-targeted, consenting list will outperform a large cold one.
