Tips & gotchas
- Phone must be E.164 (
+followed by country code + number, no spaces). Strip spaces from{{lead.phone}}upstream with a Set Variable node if your leads submit local formats. - Wasender must be connected and the session active — check /workspace/credentials if messages stop delivering.
- WhatsApp may rate-limit bulk sends. For broadcast campaigns use the Wasender dashboard directly.
