GMass Pricing: Mail Merge Plans, Cost Per Month and Send Limits

GMass has three individual plans. Standard is $29.95 a month, Premium is $39.95 and Professional is $59.95, and every one of them advertises unlimited emails. Annual billing is paid as a single yearly total rather than a discounted monthly rate, and GMass displays the effective monthly figure rounded down.

Divided across twelve months, the annual plans work out at $20.75, $29.08 and $49.92. GMass shows these as $20, $29 and $49 on its pricing page, rounding down rather than to the nearest cent, so budget from the annual total instead of the displayed monthly figure.

One small oddity worth recording, because it shows how carefully these numbers need reading. The Premium plan is displayed as $39.95, but the Stripe checkout button on that same page is configured to charge 3996 cents, which is $39.96. It is a one cent difference and nothing to worry about, but it is a useful reminder that the number a vendor prints and the number its payment processor charges are not always read from the same place.

Team plans run from $175 a month for 5 users to $2,200 a month for 100, and every one of them includes the full Professional feature set. There is no per-seat pricing between the bands, so you always round up to the next block.

That $22.00 to $35.00 per user range matches what GMass itself published when it announced its 2026 prices, which is a useful confirmation that the checkout figures above are the live ones.

The annual team plans follow one clean rule that GMass never states outright: every team plan billed annually costs exactly ten times its monthly price. Five users is $175 a month or $1,750 a year. One hundred users is $2,200 a month or $22,000 a year. You pay for ten months and get twelve, a flat 16.67 percent discount at every seat count.

There is a trap at the bottom of that ladder. The 5 user team plan costs $175 a month, but five individual Standard subscriptions cost $149.75. If your five people only need mail merge and no sequences, the team plan is $25.25 a month more expensive than simply buying five Standard seats. The team plan only starts paying for itself around ten users, where $295 undercuts ten Standard seats at $299.50, and it wins decisively against Professional seats at every band.

Because GMass does not meter volume, the tier you need is decided entirely by features. This is the part of GMass pricing that costs buyers the most money, because the cheapest plan is missing the one thing cold outreach depends on.

Professional at $59.95 adds the two rows that Premium still says no to: Inbox Rotation (MultiSend) and high-priority support. Everything else is already present on Premium.

So the practical reading is short. Standard is a mail merge plan, not a cold email plan. A campaign that cannot send a follow-up gives up most of its replies, since the second and third touches are where a large share of cold email responses arrive. If you are buying GMass for outbound, your real entry price is $39.95, and if you want to spread sending across several mailboxes it is $59.95.

Every GMass plan says unlimited emails, and from GMass's side that is true. The limit that stops you is Google's, not GMass's. GMass publishes the numbers itself: a free Gmail account can send 500 emails a day, and a Google Workspace account can send 2,000 a day.

Monthly ceilings assume 22 business days. GMass is candid that the real number often lands lower, noting from its own experience across more than 700,000 accounts that Google frequently throttles sending below the published limit.

This is why Inbox Rotation matters so much on the pricing page. MultiSend distributes one campaign across several connected Gmail or Workspace accounts, and GMass says there is no cap on how many additional accounts you can attach to a paid plan. That turns the per account ceiling into a per mailbox ceiling you can multiply, which is the only way to send serious volume through Gmail. It is also gated to the $59.95 Professional plan.

This is the part of GMass pricing that almost no comparison article covers, and it changes the arithmetic completely. GMass can send through Gmail, or it can send through an SMTP service, and those two routes are billed in entirely different ways.

The SMTP meter applies whether you connect your own SMTP account or use one of GMass's in-house servers, and it sits on top of the subscription rather than replacing it. At 50,000 emails a month that is $20 of metering added to your plan. At 100,000 it is $45.

Now compare the two routes on unit cost, because the answer is not the obvious one. A Google Workspace seat costs about $7.00 a month on an annual commitment and, at Google's stated 2,000 a day ceiling, carries up to roughly 44,000 emails a month. That is about $1.59 per 10,000, which makes the Gmail path look about three times cheaper than the $5.00 SMTP meter.

That comparison only holds if you can actually send 2,000 cold emails a day from one mailbox, and you cannot. Cold outreach deliverability caps a mailbox nearer 30 sends a day, or about 660 a month. At that realistic rate the same $7.00 seat carries 660 emails, which is roughly $106 per 10,000, more than twenty times the SMTP meter. The Gmail path is only cheap at volumes a cold email sender can never safely reach. For opt-in mail to an engaged list, the Gmail path genuinely is the bargain it appears to be. We ranked the providers that actually permit outbound on our best SMTP for cold email page.

GMass sells software, not mailboxes or domains. Those are yours to buy, and at cold email volumes they cost more than the subscription does. Using 30 sends per mailbox per day, 22 business days, three mailboxes per sending domain, Google Workspace at $7.00 per user per month on annual billing and .com domains at $11.08 a year, here is what two common targets look like.

For a like for like comparison, the same infrastructure with ColdMailer Pro at $49 comes to $107.77 at 5,000 emails a month, and with ColdMailer Enterprise at $149 comes to $266.54 at 10,000. GMass is the cheaper subscription at 10,000 emails a month, and we would rather say so than pretend otherwise. What you give up for that saving is mailbox flexibility: GMass wants Google accounts, while our plans send through Google Workspace, Microsoft 365 or any SMTP host, mixed in a single campaign.

The number worth noticing in that table is not either subscription. It is that infrastructure is 50 to 66 percent of the total bill at both volumes. Whichever platform you choose, the mailboxes and domains dominate the cost of cold email, which is why plans that charge per inbox seat get expensive so quickly. Our guide to cold email infrastructure walks through sizing the mailboxes and domains before you commit to a platform.

GMass increased every plan on January 1, 2026, and did not grandfather existing subscribers. It published the change in advance and offered customers the chance to lock the old rate by switching to annual billing before the deadline. If you are reading an article written in 2025, its numbers are stale.

Annual totals moved too, from $225 to $249 on Standard, $325 to $349 on Premium and $525 to $599 on Professional. Team plans went from a range of $18 to $29 per user to the current $22 to $35.

The Professional annual plan absorbed the largest increase, rising 14.1 percent from $525 to $599 while its monthly price rose only 9.0 percent. That is what produced the uneven discount ladder described below: annual billing now saves 30.7 percent on Standard, 27.2 percent on Premium and just 16.7 percent on Professional.

Search GMass pricing and the numbers you get back will not all match. Four specific things cause that, and each one is checkable.

First, the January 2026 increase split the internet in half. Standard moved from $25 to $29.95 and Professional from $55 to $59.95. Any article that still says $25 was written before that date and never updated, and because GMass did not grandfather anyone, the old figure is not even right for existing customers.

Second, the pricing page geo-adjusts. It carries the line "Pricing has been adjusted for United States", which means a writer in another market can be looking at genuinely different numbers on the same URL. Every figure on this page is the United States one.

Third, the team ladder is behind a toggle. The pricing page opens on the individual plans, and the five team bands only appear after you switch to the team view and pick a seat count. Writers who screenshot the default view see three prices and stop, which is why the $175 to $2,200 ladder is missing from most comparisons.

Fourth, the SMTP meter is not on the pricing page at all. The $5 per 10,000 charge after the first 10,000 SMTP emails appears in GMass's own pricing announcement and support material, not in the plan cards. An article built only from the plan cards will tell you GMass has no usage charges, and for the Gmail path that is true, but for the SMTP path it is not.

One note on how this page was built. GMass's own pages carry review ratings and we have deliberately not reproduced them, because a rating we cannot independently verify is not a fact we are willing to republish. The prices here came from the Stripe checkout buttons embedded in the pricing page, where the amount is stored in cents, cross-checked against GMass's published announcement of its 2026 prices.
