The easy, affordable way to keep in touch with your members

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

Looking for a better way to communicate with the members of your gym or sports club? (Even if it’s just to send an email before a holiday so you aren’t flooded with 2,000 calls asking “Are you open on Presidents’ Day?”)

We built GMass to be the simple, affordable option for sending your emails.

Using complex and expensive gym management software like PushPress or Glofox? Or email apps with tons of features you aren’t using, like Mailchimp? Maybe you’re just hoping the social media algorithms actually show your posts to all of your members?

Let’s make things way easier.

With GMass, you can send a personalized, individual email to every member of your gym from right inside your Gmail (or Google Workspace) account.

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

Improve communication, keep members happy, and save a ton of time and effort

Boost involvement and keep gym members engaged

Sports clubs, racquet clubs, gyms, and fitness centers around the world are using GMass to keep their members informed, engaged and active

  • Newsletters. Inform your members about news, events and activities.
  • Promotions. Running a “bring a friend” promotion or offering a discount on personal training or class packages? Don’t rely on a flier on a bulletin board. Make sure your members know.
  • Important announcements. Is a class canceled or at a different time this week? Will you have limited hours on a holiday? Get the word out. Your members might not see a social media post (after all, those are at the mercy of algorithms) — but they will receive your emails.
  • Welcome emails. Send a series of emails to new members. Introduce the staff and trainers, showcase events, and ensure new members feel welcomed and excited about what your club offers.
  • Payment reminders. Let members know when their payments are due (or overdue) — and send automated follow-ups if they don’t respond.
  • A notice when the chest fly machine is fixed. Confession: I’m just putting this in here in case the managers at my gym see this, because I love the chest fly machine and it’s been out of service for two months.
