The short answer
Both sides assessedGMass compared with Hunter Campaigns
Hunter bundles a large email-finding database with a modest sequencing tool, so you are buying data first and sending second, capped at three to twenty connected mailboxes by tier. GMass sells no data at all but sends far better, with unlimited connected accounts under MultiSend and free verification. Buy Hunter if finding the addresses is the hard part; buy GMass if you already have the list.
Hunter Campaigns compared with GMass
Opposite halves of the same job. GMass sends far better for far less, with unlimited connected Gmail accounts under MultiSend, free verification, and $59.95 flat pricing, but sells no data. Hunter finds and verifies the addresses first and caps you at twenty mailboxes. If your problem is the list, buy Hunter; if your problem is sending, buy GMass.
Choose GMass if
Solo founders, consultants, recruiters, and small teams that already live in Gmail and want a cheap, deeply capable mail-merge and cold email tool that sends from their real mailboxes, at volumes of a few hundred to a few thousand emails a day across a handful of accounts.
Choose Hunter Campaigns if
Small B2B teams whose hardest problem is finding and verifying the right contacts, who want prospecting, verification, and a modest sequencer in one bill, and who send a few thousand carefully targeted emails a month from one to twenty real mailboxes.

| Category | Cold Email | Cold Email |
| Starting price | $29.95 per month (Standard), or $249 per year (free plan available) | 0 euros free, then 34 euros per month (Starter) (free plan available) |
| Pricing model | Per-user subscription with three individual tiers and banded team plans; unlimited contacts and unlimited campaigns on every paid tier, with volume capped by Google's own per-account sending limits rather than by GMass. | Credit-based subscription quoted in euros, where one credit equals one email address found; connected mailboxes and recipients per sequence are capped by tier, and team members are unlimited on paid plans. |
| Free plan | A perpetually free level exists for low-volume sending, with a daily recipient limit and GMass branding appended to messages; verification, sequences, and reporting are limited until you upgrade. | 50 credits a month, one connected email account, 500 recipients per sequence, and basic Discover filters. Enough to test the full workflow end to end. |
| Free trial | Free tier usable immediately after install with no credit card, limited by a daily recipient cap and a GMass footer on outgoing mail | No time-limited trial; the free tier with 50 monthly credits is the evaluation path |
| Best for | Solo founders, consultants, recruiters, and small teams that already live in Gmail and want a cheap, deeply capable mail-merge and cold email tool that sends from their real mailboxes, at volumes of a few hundred to a few thousand emails a day across a handful of accounts. | Small B2B teams whose hardest problem is finding and verifying the right contacts, who want prospecting, verification, and a modest sequencer in one bill, and who send a few thousand carefully targeted emails a month from one to twenty real mailboxes. |
| Setup time | Under ten minutes for a first campaign: install the Chrome extension, authorize Gmail, connect a Google Sheet, and send. Custom tracking domain setup adds a DNS record and maybe an hour of propagation. | Under thirty minutes to a first sequence: sign up, connect a mailbox over OAuth, run a Domain Search, verify the list, and build three steps. No DNS work is required unless you are setting up a new sending domain, which you should be. |
| Learning curve | Very low to start because the campaign is a Gmail draft, but moderate to run well. The settings panel is dense, and the difference between a competent GMass user and a novice is mostly knowledge of pacing, tracking domains, and when not to send. | Low. The prospecting tools are the part with depth, and the sequence builder is deliberately simple. The habit worth teaching is verifying before every send, which Hunter makes easy enough that people actually do it. |

Strengths and limitations
GMass
Strengths
- Sending happens through real Google mailboxes with your own authentication, which is the deliverability model every serious cold email operator eventually returns to.
- Building a list from a Gmail search is a genuinely unique capability and repeatedly the reason people install GMass in the first place.
- Free unlimited email verification and free secondary sending accounts under MultiSend remove two line items competitors bill for.
- Flat per-user pricing with unlimited contacts and campaigns means budget certainty; nothing scales with list size.
Limitations
- No warm-up at all since 2023, so new domains need a separate tool and a separate bill before GMass is safe to run at volume.
- Gmail's per-account caps (about 500 recipients a day on consumer Gmail, about 2,000 on Workspace) are a hard ceiling GMass cannot raise.
- Gmail only. No Microsoft 365 support, no generic SMTP sending path for campaigns, and no plan to add them.
- Reply management is Gmail labels plus a companion triage tool rather than a true team inbox with statuses, owners, and deal stages.
Hunter Campaigns
Strengths
- Prospecting, verification, and sending in one tool with no CSV round trip, which removes the most common friction point in small-team outbound.
- Unlimited team members on every paid plan, which makes Hunter dramatically cheaper than per-seat competitors for any team above two people.
- Sends through your own Gmail, Workspace, or Outlook mailbox rather than a shared relay, so reputation belongs to your domain.
- Verification is built into the workflow rather than sold as an upsell, and it is genuinely good, which is why Hunter's bounce rates tend to be low.
Limitations
- Hard mailbox ceiling of twenty connected accounts on the top self-serve plan, which rules out any real inbox-rotation program.
- No email warm-up at all, so new sending domains need a separate vendor and a separate bill.
- No unified inbox with owners and statuses; replies land in your mailbox and are managed there.
- No spintax, no ESP matching, and a thinner deliverability toolkit than dedicated cold email platforms offer.
Pricing compared
GMass
Per-user subscription with three individual tiers and banded team plans; unlimited contacts and unlimited campaigns on every paid tier, with volume capped by Google's own per-account sending limits rather than by GMass.
- Standard$29.95
- Premium$39.95
- Professional$59.95
- Team (5 users, Premium)$175
Modelled at 10,000 emails a month, GMass Professional at $59.95 covers it with three or four connected Workspace mailboxes and costs less than most platform starter tiers once you account for the free verification and free secondary accounts. At 100,000 emails a month the arithmetic breaks down, not because GMass charges more but because you would need roughly fifty Workspace mailboxes at Google's own prices and an extension-based workflow to manage them, at which point a rotation-native platform is simply the right tool. Judged inside its range, GMass is the best capability-per-dollar in the category; judged outside it, it is the wrong architecture.
Hunter Campaigns
Credit-based subscription quoted in euros, where one credit equals one email address found; connected mailboxes and recipients per sequence are capped by tier, and team members are unlimited on paid plans.
- Free0 euros
- Starter34 euros
- Growth104 euros
- Scale209 euros
- EnterpriseCustom
Hunter is priced as a data tool, so model it that way. At 10,000 emails a month, Growth at 104 euros gives you 10,000 credits, ten mailboxes, and unlimited seats, which is competitive if you are finding most of those addresses yourself and poor value if you already have a list, since a pure sequencer like Emelia or Saleshandy would cost a third of that. At 100,000 emails a month Hunter simply does not fit: twenty mailboxes and 15,000 recipients per sequence cap you long before the credits do. The right way to read Hunter is that the sequencer is bundled with a good database rather than the other way round, and the unlimited-seats policy is the quiet feature that makes it good value for teams.
Editorial verdict on each
GMass
GMass is the best cold email tool for people who do not want a cold email platform. If you send from one to five real Gmail accounts, want free verification, want your replies in your normal inbox, and want a flat bill that never scales with list size, nothing else in this category is better value than $59.95 a month for Professional with MultiSend and free secondary accounts. The two things that should stop you are structural rather than fixable: Gmail's per-account daily cap sets a hard ceiling, and there has been no warm-up since 2023, so new domains need a separate purchase. Above roughly ten thousand sends a month, or on Microsoft 365, buy something else. Below that, GMass is a bootstrapped, profitable, decade-old product that quietly does more than tools costing three times as much.

Hunter is the right first purchase for a small B2B team that does not yet have a list, and the wrong purchase for one that does. The database, the finder, and the verifier are the product; Campaigns is a competent, deliberately simple sequencer that lets you act on what you found without exporting a CSV. Unlimited team members on every paid plan makes it cheaper than nearly any per-seat rival once more than two people are involved, and a bootstrapped decade-old vendor is worth real money in a category this volatile. The two things to be clear-eyed about are the twenty-mailbox ceiling and the total absence of warm-up. Neither matters at a few thousand carefully targeted emails a month, and both are disqualifying above that. Buy Hunter as your prospecting engine that also sends, not as your sending engine that also prospects.
