GMass review: pricing, limits and verdict
GMass is a Gmail extension and cold email sequencer tool. Its cheapest paid plan is Standard at $29.95 per month billed monthly, priced per user. In our default scenario (50 inboxes, 40 emails per inbox per day, 50,000 prospects) GMass is not ranked because its plans do not publish a mailbox limit that covers it.

Research notes on GMass's pricing page
Pricing page has Individual/Team and Monthly/Annually toggles; all variants are present in the HTML (data-plan-col v002m/v002a = Standard, v003 = Premium, v004 = Professional; t5/t10/t25/t50/t100 mv/av = Team 5/10/25/50/100 users monthly/annual). Prices are printed as split tokens ('$', '29', '.95', '/ month'); source_quote reproduces the saved text lines joined with newlines. Annual prices are shown per month with the yearly total ('$249 paid annually'). Individual plans are sold per Google account ('Enter the email address of the Google account you want to subscribe'); users=1 is inferred from the 'Individual' toggle. Team cards are labelled 'Premium' but tick all 16 features including Inbox Rotation (MultiSend) and High-priority support, i.e. the Professional feature set; billing_unit=workspace because one price covers the stated user count. Individual Standard lacks Sequences and follow-ups, API access (+Zapier), A/B testing, Triggered Emails, Inbox Rotation (MultiSend), High-priority support; Premium lacks Inbox Rotation (MultiSend) and High-priority support; Professional includes all. 'Send unlimited emails!*' carries the footnote 'Prices are in USD. *Breaking limits depends on individual account configuration. See information on sending limits.' The linked limits page (https://www.gmass.co/g/limits, redirects to the blog post 'How many emails can you really send with GMass and Gmail? [2026]') states: 'Gmail officially claims that with a regular Gmail account you can send 500 emails/day and with a G Suite account you can send 2,000 emails/day' - these are Google's caps, not a GMass plan limit, so emails_per_day is left null. No free plan card is shown; the page says 'Start your free trial of GMass now ... no credit card or sign up form required' without a trial length, so free_plan and free_trial_days are null. A more detailed Google-Sheets pricing table is linked but was not fetched. G2 rating from Wayback snapshot dated 2026-02-01. Capterra: Wayback snapshot of the product page (2026-09-21) rendered without a rating block and the /reviews/ snapshot (2023-02-20) is a 403 page, so Capterra is unverified.
