Google Postmaster Tools vs Mailreach

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

Starting price

Google Postmaster Tools

Free Free tier

Google Postmaster Tools is Google's own free dashboard for how Gmail rates the mail you send to personal Gmail accounts. Every cold email sender targeting Gmail inboxes should have it set up on each sending domain. It costs nothing and needs only a Google account and a DNS record per domain.

Where Google Postmaster Tools fits

Any sender emailing personal Gmail addresses
Agencies checking Gmail compliance before scaling a domain
Recruiters sending to candidates on Gmail accounts
Teams that want the official spam rate number for free

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

Google Postmaster Tools

Stands out: It is the only place to see the user-reported spam rate and compliance status Gmail itself measures you on, where third-party tools estimate placement from seed tests. Paid tools such as GlockApps and Warmy pull their Gmail reputation data from this same source.

Watch out: Data covers only personal Gmail addresses, so it says nothing about Google Workspace or Microsoft 365 inboxes, which is where most B2B recruiting outreach lands. Low volume domains often show no data at all, and dashboards lag by about a day.

Not the right fit for

Low volume senders whose dashboards stay empty
B2B outreach aimed mainly at company inboxes on Workspace or Microsoft 365
Anyone needing real-time alerts or inbox placement tests

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

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
