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

Mailercloud

Stands out: A hosted MCP server lets Claude, ChatGPT or Cursor run campaigns, contacts and stats using your Mailercloud API key.

Watch out: Premium is priced by contact count, so 10,000 contacts cost about $50/mo. The transactional Email API is billed separately from $7/mo.

Not the right fit for

  • Sales teams that need cold email sequences
  • Senders who want pay-per-email pricing
