With YAMM, sending emails to remaining rows without sending duplicates to former recipients is very easy. This article will explain you how to do so.
If you have initiated a first mail merge in your spreadsheet but didn't complete it (for example because of quota limits), or if you have added new recipients to your mailing list, then you are probably looking for a simple way to finish your campaign without risking to send your email again to recipients who have already received it.
In the following example, we want to send our campaign to the last four rows (row 12 to 15), as the previous ones have already received the email:
To do so, just start your second mail merge ('Add-ons > Yet Another Mail Merge > Start Mail Merge'). You should then notice a new information on the pop-up window, which indicates that 'Rows with a valid merge status will be skipped':
Here is the full list of all valid merge statuses, which will be skipped by YAMM:
However, 'EMAIL_NOT_SENT' and 'ERROR' will not be skipped.
