Mailreach vs MxToolbox

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

MxToolbox

$129/mo Free tier

MxToolbox is the free DNS and blacklist lookup site most email admins already know, with paid Delivery Center plans for DMARC, inbox placement and blacklist monitoring. It suits agencies that want to check a domain setup fast for free and, at scale, monitor every sender on their domains. The free plan covers 1 domain, paid plans start at $129/month, and no free trial is stated.

Where MxToolbox fits

  • Quick free checks of MX, SPF, DKIM and DMARC records
  • Checking whether a sending IP or domain is blacklisted
  • Teams moving a main domain to DMARC reject
  • Agencies monitoring third-party senders on client domains

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

MxToolbox

Stands out: Its free lookups need no account and check a sending IP against 100+ blacklists in seconds, which is quicker than signing up for a testing tool. Adaptive blacklist monitoring watches every third-party service sending as your domain, not only the IPs you list by hand.

Watch out: The jump from free to $129/month is steep, and both paid plans cap you at 5 domains, which a cold email setup with many domains can outgrow. There is no warm-up and inbox placement covers only Google, Yahoo and Outlook.com.

Not the right fit for

  • Cold email setups spread across more than 5 domains
  • Anyone needing mailbox warm-up
  • Small senders who want cheap paid monitoring

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

MxToolbox

  • Free lookups with no account
  • Blacklist check against 100+ lists
  • REST API for lookups and monitors
  • Paid plans start at $129/month
  • 5 domain cap on both paid plans
  • No warm-up or free trial stated
