GMass Pricing in 2026: Plans, Costs & Is It Worth It?
GMass is a Gmail-based cold email and mail merge tool that lives inside your inbox as a Chrome extension. Individual plans start at $29.95/month after a January 2026 price increase. Annual billing brings the effective cost down to $20.75/month. Here is the full breakdown.
Individual plans
All individual plans include unlimited emails, unlimited contacts, unlimited campaigns, mail merge, open/click tracking, auto follow-up sequences, and A/B testing. The difference between tiers is advanced features and support priority.
| Plan | Monthly | Annual | Key Extras |
|---|---|---|---|
| Free Trial | $0 (7 days) | – | 50 emails/day, all features unlocked |
| Standard | $29.95/mo | $20.75/mo ($249/yr) | Unlimited emails, contacts, campaigns, sequences |
| Premium | $39.95/mo | $29.08/mo ($349/yr) | Everything in Standard + MultiSend (inbox rotation) |
| Professional | $59.95/mo | $49.92/mo ($599/yr) | Everything in Premium + highest priority support + all pro features |
Prices verified from gmass.co/pricing as of April 2026. Note: GMass raised prices in January 2026, Standard went from $25/mo to $29.95/mo.
The Standard plan covers most use cases. The main reason to upgrade to Premium is MultiSend, which rotates sending across multiple Gmail accounts to spread volume and protect deliverability.
You want to rotate sending across 5 Gmail accounts to stay under daily limits. Which GMass plan do you need?
Correct! MultiSend (inbox rotation across multiple Gmail accounts) is only available on Premium ($39.95/mo) and Professional ($59.95/mo). Standard does not include it.
MultiSend is a Premium feature. Standard includes unlimited emails from a single account, but rotating across multiple Gmail accounts requires Premium ($39.95/mo) at minimum. Professional adds priority support but is not required for MultiSend.
Team plans
GMass team plans give every team member access to Professional-tier features. Pricing scales with team size, and you get centralized billing and shared campaign analytics. Contact GMass directly for exact team pricing based on your headcount.
What every paid plan includes
- Unlimited emails, no per-email or per-campaign caps (subject to Gmail sending limits)
- Unlimited contacts, import as many recipients as you need
- Mail merge, personalized mass emails from Gmail with Google Sheets integration
- Auto follow-ups, stage-based follow-up sequences triggered by recipient behavior
- A/B testing, test subject lines and email body variations
- Open and click tracking, real-time campaign analytics inside Gmail
- Scheduling, send emails at optimal times
Hidden costs to watch for
- Gmail sending limits still apply. Personal Gmail caps at 500 emails/day. Google Workspace caps at 2,000/day. GMass cannot override these limits.
- MultiSend costs extra. Inbox rotation across multiple Gmail accounts is only on Premium ($39.95/mo) and above. On Standard, you are stuck with one account's daily limit.
- No built-in prospect database. GMass does not include a contact finder. You need a separate tool like Apollo, Hunter, or an email verifier to build your lists.
- Google Workspace is a separate cost. To get the 2,000 emails/day sending limit (vs. 500 on free Gmail), you need Google Workspace at $7.20/user/month minimum.
- No dedicated sending infrastructure. On Standard, all emails route through Gmail's servers. There is no custom SMTP or dedicated IP option.
You are on GMass Standard and want to send 3,000 emails in a single day from one Gmail account. What happens?
Correct! GMass "unlimited emails" means no GMass-imposed cap, but Gmail's own limits still apply. Personal Gmail stops at 500/day, Google Workspace at 2,000/day. Emails beyond the limit will fail to send.
"Unlimited emails" in GMass refers to no GMass-imposed limit, not bypassing Gmail's infrastructure limits. Personal Gmail accounts cap at 500 emails/day, and Google Workspace caps at 2,000/day. To send more, you need MultiSend (Premium plan) to rotate across multiple accounts.
What is the real minimum monthly cost to use GMass for cold outreach with 2,000 emails/day sending capacity?
Correct! Free Gmail only allows 500 emails/day. To reach 2,000/day you need Google Workspace ($7.20/user/month), bringing the real minimum to $29.95 + $7.20 = $37.15/month.
GMass Standard on a free Gmail account only gets you 500 emails/day. For 2,000/day capacity, you need Google Workspace ($7.20/user/month) on top of GMass. The real cost is $29.95 + $7.20 = $37.15/month. Premium is not required unless you need MultiSend.
Is GMass worth the price?
Worth it if you:
- Need simple Gmail mail merge with personalization and auto follow-ups
- Run small to medium campaigns and stay within Gmail sending limits
- Already use Google Workspace and want to send directly from your inbox
- Prefer a Chrome extension over a standalone platform
Not worth it if you:
- Need high-volume sending beyond Gmail's 2,000/day limit per account
- Want built-in prospect finding without a separate subscription
- Need multichannel outreach (email + LinkedIn + calls)
- Focus on link building automation rather than sales outreach
