Choose whether emails are sent as new messages to each recipient or as replies to your last conversation with each recipient. If you have no prior conversation with a recipient, the email will be sent as a new message. If you do have a prior conversation with the recipient, the email will be sent as a reply, and the Subject of your email campaign will be ignored, since the Subject of the last conversation will be used.
Personalize the Subject and Body with the following insertions: {FirstName} {LastName} and {EmailAddress}. If you connect to a Google Sheets spreadsheet with other columns, you can personalize to your heart's content. {Company}, {City}, {DateOfBirth}, {CouponCode}, and any other column for which you have data can be used.

GMass was born out of the frustration of its creator, Ajay Goel. While recruiting writers for his other Gmail product, Wordzen, he was disheartened by how difficult it was to communicate with all of his writer prospects at once. He simply needed to inform the five candidates that the position was of the 1099 and not W2 variety, but to his dismay, he had to find each conversation with each editor, hit Reply, and type a personalized message. Ajay has lots of experience building email products, especially mass email products. He also built JangoMail, which was acquired by a private equity group in 2013.
