Select Extensions > Yet Another Mail Merge: Mail Merge for Gmail > Start Mail Merge.

The Start Mail Merge window opens, showing the column YAMM detected for the email addresses and how many emails you can still send today. YAMM is running: from here you pick your Gmail draft and send your campaign.

On an empty spreadsheet, the mail merge window does not open. YAMM reports There are no recipients in your sheet and offers to import contacts instead. Click Add emails myself to close the window, add at least one email address to your sheet, then launch YAMM again.
