If you have stopped publishing (sending) your project in the middle you may resume from where Yeshiva left off. When you stopped and saved the project, the Start button will have turned to Resume when you reopen the project.
Generally, Email Marketer will try to resend the failures automatically unless you click the Stop button.
There are two options to resend
the failures manually from the Publish tab:
1. If the Resume button is enabled, just click it to resend the failures;
2. If the Resume button is disabled, please click the Options and Performances button and add to the retries field. Then click Resume;
3. To resend a single failure message, please click Failure Details and double click the failure item. Click the Send This Message button at the new dialog.
