Simple and powerful email marketing inside Gmail™. *Send email marketing campaigns to thousands of email addresses. *Mail merge with data from Google Sheets™. *Personalize mass emails based on name, email address, and any available columns in Google Sheets™. *Schedule mass emails to be sent later. *Track opens and clicks. *Send follow-up emails to people that opened, clicked, or replied to a previous campaign, or to those that did NOT open, click, or reply. *See all reports right in your Gmail account, under the "GMass Reports" Label. *Create instant recipient lists based on search results. *Send unlimited emails from your Gmail™ account by connecting your GMass account to an external SMTP service like Sendgrid. *And the killer feature - emails can be sent as replies to the last conversation you had with each recipient. Note that the GMass Add-on must be paired with the GMass Chrome extension for full functionality. The Add-on allows you to see statistics on sent emails and add people to your "Unsubscribes" list, but the Chrome extension is needed to launch email campaigns: https://chrome.google.com/webstore/detail/gmass-powerful-mail-merge/ehomdgjhgmbidokdgicgmdiedadncbgf We're always improving GMass.
