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

Very useful tool for mass emails, better than instantly!! Although the user aesthetic might not be as sophisticated the capabilities are just as good if not better and very reasonably priced for the market. Highly recommend if you're looking to do mass cold email campaigns

I've been using GMass for the past two years, and I'm consistently impressed. Last year, it helped me generate great results with my clients. I typically send around 1,000 emails per week, totaling 10,000 emails each year. This year, I'm back again to send another batch of emails (over 10,000) and confident in GMass's ability to deliver. It's a user-friendly and effective tool, and I highly recommend it.
