Compare/Head to head

Mailreach vs Unspam

Same facts, side by side: starting price, free tier, MCP, API and what each one is actually built for.

Starting price

Mailreach

$20/mo

Mailreach is email warmup and deliverability for cold outreach inboxes. The listing floor is $20/mo.

Where Mailreach fits

  • Cold emailers warming Google Workspace or Microsoft inboxes
  • Agencies that want spam tests next to warmup, not warmup alone
  • Senders on a sequencer that does not include a strong warmup network
  • Teams comparing a $20 warmup seat with Folderly's $79 monitor

Unspam

$5/mo Free tier

Unspam is a pre-send spam checker that scores an email, tests inbox placement and previews it in real email clients. It suits recruiters and small agencies who want to check a BD template or sequence step before it goes out, without paying for a full deliverability suite. There is a usable free plan, and the paid Custom plan is pay per test from a $5 monthly minimum.

Where Unspam fits

  • Recruiters testing a cold email template before launch
  • Small agencies that want pay per test pricing
  • Teams who want AI explanations of spam warnings
  • Builders who want to run spam tests from Claude or ChatGPT

Where they pull apart

Mailreach

Stands out: Warmup plus spam tests and blacklist checks in one warmup-first product, a step up from a $15 warmup-only bot.

Watch out: Mailreach does not host your sequences. Instantly and Smartlead already ship warmup, so a separate $20 seat is extra unless you send from Google or Outlook directly.

Not the right fit for

  • Users who already get warmup inside Instantly and do not want a second bill
  • Buyers who need seed-list inbox placement graphs more than a warmup network

Unspam

Stands out: Unspam combines a spam score, seed list placement test, 50+ client previews and an AI assistant that explains fixes, and the free plan already includes 21 tests a month plus the AI assistant. Its pay per test Custom plan starts at $5 a month, far below the flat monthly fees of most placement testers.

Watch out: The API, MCP server, DMARC monitoring and scheduled tests all need the paid Custom plan, and the free plan keeps results for only 14 days. It tests and diagnoses emails but does not warm up mailboxes or send campaigns.

Not the right fit for

  • Teams that need mailbox warmup
  • High volume senders wanting a flat unlimited plan
  • Anyone who needs results kept long term on a free account

Pros and cons

Mailreach

  • Published $20/mo listing with warmup plus spam tests
  • Works alongside Gmail, Microsoft, or a sequencer
  • Unbundled, so you are not forced into one sending UI
  • A second bill if your sequencer already warms mail
  • Not an inbox-placement suite at Folderly depth

Unspam

  • Free plan with 21 tests a month
  • AI assistant explains each fix
  • Pay per test from $5 a month
  • API and MCP only on paid plan
  • Free results kept 14 days
  • No warmup or sending
