Overview
A powerful mass email and mail merge system for Gmail™. 

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

I admire the simplicity GMass adds to Gmail with its sidebar functions. The ability to view recipient information and manage campaigns directly in Gmail is a huge bonus. However, I experienced occasional lags while using the add-on. Overall, a solid email marketing tool, and I am looking forward to future improvements to improve the experience.

GMass is an incredible tool for sending cold emails! 🚀 I’ve tried other platforms like Brevo, AWeber, and GetResponse, but GMass really takes the lead. It lets you schedule emails, control the send intervals in large campaigns, and keep your outreach seamless. Highly recommend for anyone looking to level up their email game! 💌✨

I used GMass to send my wedding save the dates, it was easy to follow the detailed instruction pages for this. It may be difficult to figure out on your own but GMass seems to have a lot of 'how to' pages which is great. Integrates within Gmail very well, and overall very user friendly!
