"Loved using GMASS to send a direct message to multiple contacts. It looks like a regular personal email and so easy to use."

"Its direct integration natively within the Gmail UI makes it super smooth. It's very easy to send auto followups, link to preexisting google sheets and track responses and link clicks. It's not flashy or pretty like some email systems, and it does spam your secondary inbox with notifications of red receipts and clicks. But that only gets in the way when I go searching my history for a specific email address. It's made it very easy to send mass emails in a way that is personalized and doesn't require the integration of an outside website like Mailchimp. I find that less of my large emails end up in peoples spam folders."

"Great extension, easy to use and full integration with google sheets. It uses gmail as user interface and (optionally) as mail server to send emails to lists prepared in google sheets. Alternatively, one can use other service providers such as smtp2go or a private mail server."

"This a really nice complemental service to Mailchimp. Easy to use and tap in to begin sending emails. Not complex at all and there's plenty of blog posts and videos that are on GMass's website that I followed first before diving straight in. All of their support materials were top notched which helped me jump in right away. I LOVE being able to tap into Google Sheets which our sheets are always updated with new contacts, so that auto-update feature is really nice."
