What is Gamma’s email format?
Format | Example (fictional name: Maya Chen) | Who uses it | Status |
|---|---|---|---|
{first}@gamma.app | maya@gamma.app | Early staff and many engineers, 2021 to 2026 | Most common |
{first}.{last}@gamma.app | maya.chen@gamma.app | Several staff who joined in 2025–2026 | Common for newer staff |
{anything}.gamma.site | yoursite.gamma.site | Free websites made by Gamma users | Not an email domain |
We found 11 Gamma staff addresses that Gamma or its people published themselves: in commits to Gamma’s public code on GitHub (GitHub), in the maintainer lists of its developer packages and in Gamma’s own help center. Five use the first name only, including the oldest, from 2021; four use first.last, all of them first seen in 2025 or 2026. The rest are one-offs. Try maya@gamma.app first, and maya.chen@gamma.app for someone who joined recently.
The sample is small and leans toward engineers, so treat either pattern as a guess: run the address through an email verifier before you send, because a bounce hurts your sender reputation.
Which addresses does Gamma send from?
hello@gamma.app: sign-in and verification codes.
notifications@gamma.app, with the sender name “Gamma”: workspace invitations (Gamma).
support@gamma.app: replies from Gamma’s support team.
Receipts and invoices come through Gamma’s payment provider, also from gamma.app.
gamma.app runs on Google Workspace. Its DMARC policy is quarantine, so mail that fakes a gamma.app address is usually sent to spam rather than blocked outright (DNS checked November 10, 2026).
Why most “Gamma” links aren’t from Gamma
Gamma is a tool for making presentations, documents and websites, and anyone can publish one free. A link to gamma.app/docs/… is a presentation or document a Gamma user made, and yoursite.gamma.site is a free website a user published (Gamma). gamma.site has no email set up at all, so a message “from” a gamma.site address is fake.
Is that email from Gamma real?
Scammers use Gamma pages as a stepping stone. In April 2025 Abnormal Security described emails, sent from a real but hacked account, with a link to a Gamma presentation whose “Review Secure Documents” button led to a fake Microsoft SharePoint login (Abnormal). The emails were ordinary messages with a link, not Gamma’s own sharing notifications, which helped them avoid Gamma’s content checks (Paubox).
Check where the login is. A Gamma page that asks you to sign in to Microsoft, Google or a bank is phishing. Gamma’s own sign-in is on gamma.app and sends codes from hello@gamma.app.
Check the sender. Gamma’s mail comes from gamma.app. A message about “your Gamma account” from Gmail, Outlook or a look-alike domain isn’t Gamma.
A trusted sender can be hacked. Phishing that links to Gamma has come from real accounts that attackers took over, so a known name isn’t proof.
Report it. Use the small flag icon next to the “Made with Gamma” button on the page, or email the link to abuse@gamma.app (Gamma).
