Where they pull apart

GMass

Stands out: Every plan sends unlimited emails from your own Gmail account and includes free address verification.

Watch out: Standard has no follow-up sequences, A/B tests or API. Those start on Premium at $39.95/mo, and inbox rotation needs Professional.

Not the right fit for

Teams not on Gmail or Google Workspace
Buyers who need sequences on the cheapest plan

Mailmeteor

Stands out: Starter at $5.99/user/mo lifts the cap to 250 emails per day and 5,000 per month, still sending through your Gmail or Google Workspace account.

Watch out: Consumer @gmail.com accounts stay capped by Google at 500 emails per day even on paid plans. Higher volume needs Google Workspace or your own domain.

Not the right fit for

Cold outbound teams that need dedicated IPs and a warmup network
Microsoft 365 shops that will not move the campaign into Gmail
