One-to-one SendBlue messages containing links can now be sent only after the contact replies to the same sending number. If you try to send a link before that reply, you’ll see a clear explanation asking you to remove the link or wait. Automations and scheduled sends are checked too.
If an automation text is blocked, that step is marked skipped and the remaining steps continue.
SendBlue rejection details are also clearer, helping you understand why a message failed instead of seeing only “Bad Request.”
