ImprovedEmail APIEmail logs
The Retry button on a held email now works, and Retry an email accepts emails with the status held. Fix the reason the email was held first, for example a high spam score or missing credits, then retry it.
A retry creates a new email with a new ID and costs credits like any other send. Emails older than 30 days, or whose content was removed by data retention, can’t be retried. See Retry and forward.
