If you start a campaign and notice that mails don't get delivered at all you can check in the message & error log of the campaign for any log entries that might indicate the nature of the problem. If you don't see any log entries there are a few possible reasons for this behavior:
- No new recipients: If you press “START” for a campaign that has been started & stopped before (so mails already have been sent out once before), the mails won't be resent (only the webpage will be started and the links become available again). To resend the mails in such a scenario please use the “RESTART” button. Please check out this section for more info.
