If you’re sending your campaigns, you’ll sometimes get subscribers marked as errors.
This can have several reasons
- The email address is invalid
- The domain doesn’t exist
- The email was rejected by the server
Most of these errors are “subscriber-based,” which causes the subscriber to get marked as “error”, but the campaign still continues to send its messages. Sometimes Mailster cannot determine if an error is “campaign-based” and will trigger it as “subscriber-based”.
This causes a list of subscribers with an error status and a finished campaign.
In most cases, the server rejected your email mostly because of:
- reaching sending limits
- send to many blacklisted mails
- other technical reason
Please contact your email provider for a detailed explanation.
You can quickly change the status by choosing the option from the Bulk Action dropdown.
