Yet Another Mail Merge

Yet Another Mail Merge is a Google sheets icon that can produce an email merge up to 200 (PER 24 HOURS PERIOD!) at a time. It will also indicate if an email has been sent.

It needs a Google sheet with email addresses and any information fields you want to merge, and a draft email with fields the same as the information columns in the Google sheet with << >> around them (i.e. <<First Name>> <<Last Name>>).

You find Yet Another Mail Merge in Add-ons, and have to accept it to use it. Then it will be added to the add-ons menu and you can use it.
