About GMass

GMass is an easy to use email marketing service that can be used inside Gmail. It is a cold email service that helps businesses to get higher open rates by sending mass emails to their prospects. The employees can use Gmail to send mail merge campaigns and automatically generate follow-up emails. The software can also connect to Google sheets, create email lists from the Google account, and even send emails as replies to the last thread. The users can personalize, schedule, and even track opens and clicks. The highlight of this service is that it can send automatic follow-up emails until a reply is received. Some other features include personalization, scheduling, preview mode, behaviour based campaigns, and even an option to unsubscribe. GMass allows users to send big email campaigns by breaking Gmail’s sending limit. It also provides detailed analysis and reports regarding the number of people who opened, clicked, replied, and bounced. One important consideration is that the service requires Chrome to run.
