CMass has three plans: Free, Pro, and Team. You can do real work on Free; Pro removes the sending caps for when you're ready to scale up; Team adds a shared contact pool and analytics for working alongside colleagues.
Free plan
Every CMass account starts on Free. You get the full toolset — Gmail mail merge, merge tags, optional AI personalization, follow-up sequences, the Contact Intelligence sidebar, tracking, and image hosting. The one limit is campaign size:
- ▸Up to 50 recipients per campaign
- ▸All core features included
Pro plan
Pro removes the per-campaign recipient cap so you can send to your full list (within Gmail's own daily sending limits, which always apply). You keep every feature from Free — Pro is about volume, not unlocking tools.
Team plan
Team is for working alongside colleagues out of one shared workspace. It includes everything in Pro for every seat, plus a shared layer that solo plans don't have:
- ▸Up to 5 seats — the owner invites teammates by email, and they join in one click
- ▸A shared contact pool — one source of truth instead of separate, overlapping lists
- ▸Shared relationship history & scores — any seat sees the engagement and touchpoints a teammate's campaigns created, so you don't cold-email someone a colleague already knows
- ▸Team-wide unsubscribe & bounce suppression — one opt-out protects everyone
- ▸A team analytics dashboard that rolls up every member's campaigns
- ▸2,000 emails per day, which pairs naturally with a Google Workspace account
Setting up a team has its own walkthrough — see the 'Set up your team and invite colleagues' guide.
How to upgrade
Upgrading takes one click — there are no codes or keys to copy anywhere:
- 1Click Upgrade to Pro — from the plan screen, or from the prompt that appears when a campaign goes over the Free recipient cap.
- 2Enter your payment details on the secure checkout and confirm.
That's it. The moment your payment goes through, your account flips to Pro and the recipient cap lifts right away — no extra steps, no signing out and back in.
Renewals & cancellation
Pro renews automatically each billing cycle. You can cancel anytime — your Pro features stay active through the end of the period you've already paid for, then your account simply returns to Free. Your contacts, campaigns, reports, and history all stay intact; you're just back under the 50-recipient-per-campaign cap until you upgrade again.
Checking your current plan
Your current plan is shown in CMass's billing section, and it always reflects your live subscription status — so it stays accurate right after an upgrade or a cancellation.
