Before starting this tutorial you will need a Google spreadsheet that contains the contacts information with the mandatory Email column. A tutorial to make one can be found in KB0021423.
You will also need an email template saved in the Drafts folder of your Gmail account. A tutorial for making that draft can be found in KB0021436
Once you have these two other prerequisites ready you can begin.
1. In Google Sheets, open the spreadsheet with the contacts list.
2. Select Extensions > Yet Another Mail Merge: Mail Merge for Gmail > Start Mail Merge.
3. In the Start Mail Merge window, configure the mail merge.
a. Note that YAMM correctly detects column A as the Email column.
b. Type the name from which you send the mail merge in the Sender Name text box.
c. Select the email template from the Email Template drop-down menu.
NOTE - If the drafted email template does not appear in the list, click the Refresh button.
4. Click the Send emails button to send the mail merge to all recipients in the Google spreadsheet.
NOTE - Closing the spreadsheet pauses the sending process. You can then reopen the spreadsheet at any time, and YAMM seamlessly resumes sending the mail merge from where it left off.
IN CLOSING
You can check the sent emails by opening the Sent folder in Gmail. If you enabled tracking of the mail merge, opening any of the sent emails impacts the Opened number of emails in the Tracking Report. Because of this, only review the sent emails and do not open them to avoid misrepresentations in the data in the Tracking Report.
