The amazingly easy way to keep in touch with your members

Send personalized mass emails from right inside Gmail, no complex software required

Announcements, events, news, fundraising, a sign-up form for a bake sale (I always volunteer to bring napkins and a smile, which is why people don’t really like me).

No matter what your message is to your club, community, organization, school, D&D guild, the most reliable way to reach your members is with email.

But as you’ve almost certainly seen, email platforms like Mailchimp can get expensive and unnecessarily complicated.

That’s why we built GMass to be the simple, affordable option for sending your emails.

Send a personalized, individual message to every member of your organization from right inside your Gmail account.

If you know how to send an email, you’ll know how to send a mass email.

Boost involvement and keep members engaged

Communities and organizations around the world are using GMass to keep their members informed, engaged and active

  • Newsletters. Inform your members about news, events and activities.
  • Recurring reminders. Schedule recurring reminders to go out automatically, whether you’re reminding members to pay dues or sending out a monthly schedule of activities.

  • Welcome emails. Send a series of emails to new members. Introduce the leaders and the community, showcase events, and ensure new members feel welcomed with open arms.
  • Charity opportunities. Keep members informed about opportunities to head into the community to make a difference.
