Starting price

Allegrow

$99/mo 14 day free trial

Allegrow is a B2B email verification platform built for catch-all domains, secure email gateways and spam traps, with a deliverability toolkit on top. It suits agencies and sales teams emailing mid market and enterprise contacts who need conclusive answers on hard to verify addresses. Starter costs $99 a month, Scale Plus is $1,340 a month billed annually, and there is a 14 day free trial.

Where Allegrow fits

  • Agencies emailing enterprise hiring managers behind Proofpoint or Mimecast
  • Outreach and Salesloft teams wanting in cadence verification
  • Teams worried about spam traps hurting domain reputation
  • Claude users who want verification and reputation checks in chat

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

Where they pull apart

Allegrow

Stands out: Beyond catch-all verdicts, Allegrow detects spam traps and known complainers and tags the primary mailbox for each contact, which most verifiers like ZeroBounce or NeverBounce do not attempt. Its Scale Plus plan offers unlimited verification inside HubSpot, Outreach and Salesloft, and it runs an official Claude connector.

Watch out: The jump from Starter at $99 a month to Scale Plus at $1,340 a month billed annually is steep, and native integrations sit only on Scale Plus. API access on Starter is by request only.

Not the right fit for

  • Solo recruiters on a tight budget
  • Teams that only need occasional CSV cleaning at low cost
  • Buyers who want native integrations on an entry plan

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

Pros and cons

Allegrow

  • Conclusive catch-all and gateway verdicts
  • Spam trap and primary mailbox detection
  • Official Claude connector
  • Big price jump to Scale Plus
  • Native integrations only on Scale Plus
  • API on Starter by request

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
