GMerge - Mail merge and send mass emails from unlimited Gmail accounts.

Gmail is great for sending a handful of cold emails, but it’s not designed for sending mass personalized emails and follow ups.

GMerge transforms Gmail into a scalable email marketing application.

Add unlimited Gmail accounts to GMerge and use them in rotation to send personalized, individual emails to thousands of contacts. They are sent using the in-built scheduler designed to get your emails opened.
