You need a Gmail or G Suite account and the Chrome browser.
Click Compose in Gmail. Enter a few email addresses in the To field. Put in a Subject and Message, and hit the GMass button (instead of the normal Gmail Send button).
GMass is lightweight and unobtrusive. After you install GMass, you will notice four extra buttons within your Gmail interface. Three of these buttons are small square buttons to the right of the search field: the "Build Email List" button, the "Google Sheets Connect" button and the "Follow-up Campaigns" button. When composing an email, you'll notice the main GMass button along with a settings box, next to the regular Gmail Send button. Lastly, you'll see some new Gmail Labels on the left where we store reports, like open and click reports.
Most mass email campaigns are sent as new messages, and therefore new conversations, with each recipient. The ability to send a mass email and have each individual email sent as a reply to the last conversation with each recipient, creates a more familiar experience for the recipient than a new message would, because the email campaign is threaded within the conversation. If there is a recipient in your list with whom you have not had a prior conversation, then a new message will be sent. Details on this feature.
This option is useful if you want to test GMass’s functionality but don’t want to actually send anyone emails. For example, if you want to ensure personalization is working, this option comes in handy. You can also use the "Send Test Email" button to test personalization. Details on this feature.
Auto follow-ups are the best thing to happen to email marketers since well...email marketing. Auto follow-ups allow you to send follow-up emails automatically to recipients of your email campaign that have not replied. The auto follow-up sends as part of the same conversation as the original message, making it appear like you're manually hitting Reply on the original sent email to ping the person you're targeting, but in reality, this is all happening automatically. If someone doesn't respond to your first email, an auto follow-up is the best way to get them to reply. Details on this feature.
Yes. You compose your email just as you would any other email message in Gmail. Any feature of an email that Gmail supports you can assume that GMass also supports.
Maybe. It's up to you. Some users use GMass alongside their primary email marketing system, using GMass for lower-volume campaigns and their main system for bigger campaigns. GMass can handle campaigns of up to a few hundred thousand recipients using the SMTP connection feature. GMass is not designed to send a campaign to millions of addresses. One way GMass supplements your actual email marketing system is by making it easy to follow up with everyone that replied to a campaign sent through a traditional ESP. Assuming the replies go to your Gmail account, use GMass to search for the replies, then use the Build Email List feature.
With the standard setup, your emails are sent from Gmail’s servers from your Gmail or G Suite account. You’ll see all sent messages in your “Sent Mail” folder, just like you would a regular email. The benefit of this is that you get to take advantage of Gmail's sending reputation. You will likely see higher open-rates than you've ever seen before with any other email marketing system. You can see our system-wide open rates by domain. If you connect your account to an external SMTP server, you can send virtually unlimited emails from your Gmail account.
Under the standard setup, Google imposes a limit of 2,000 sent emails/day for trusted G Suite users, and 500 emails/day for regular Gmail users. There are other factors that determine sending limits too, such as the age and reputation of your Gmail account. GMass allows you to send unlimited emails by sending through an external server like Sendgrid, and GMass allows you to artificially break Gmail's limits when sending through Gmail by distributing your emails over multiple days if your campaign exceeds your account's daily limits.

You can access your open-tracking, click-tracking, and unsubscribe reports by clicking on the GMass Reports Label on the left of the Gmail interface. Note that this Label only appears after you have at least one reporting event take place, meaning at least one email open, one link click, or one unsubscribe. Note that you must click the tiny expansion arrow next to "GMass Reports" to expand and see other report categories. More details on reports.
You can search based on any number of criteria and fields, from text in the Subject and Message, to Dates sent and received, and you can even use boolean operators. Google has a great web page on Gmail advanced searches. After nailing your search critiera just hit the GMass red magnifying glass button to build your list and send a campaign. More details on this feature.
GMass is free to send 50 emails per 24 hours. To send more than 50 emails per day, please subscribe to a paid plan.
No. GMass connects to Gmail's API to operate, and that requires you granting GMass access to certain parts of your account through the API. GMass staff will never see your email, and in fact, even when you use GMass to send emails, we don't store the contents of your email messages. We only store the recipient addresses and the Subject lines, so that we can provide Open and Click Reports.
The GMass Chrome extension is our main product, and is what adds the buttons to your Gmail account so you can send mass email campaigns. Our other products supplement the Chrome extension. Our Inbox, Spam, or Promotions tool tells you what Gmail folder your emails are landing in. Our SMTP tester helps you test your SMTP settings when you're using GMass to send unlimited emails via a third-party SMTP server. Our Domain Stats Tool shows you deliverability and other information on millions of domains.
