Short answer: MailReach is a focused email warmer and spam tester and it prices per mailbox. That's $25 a month for one to five mailboxes and down to $16 at 51–100. Warmy is an all-in-one deliverability platform and it prices by warm-up volume from $49 a month. Every plan comes with a 1M+ mailbox network and a 500,000+ US seed list and placement tests and DMARC monitoring and email verification.

For one to five mailboxes MailReach usually costs less. At around ten mailboxes the price is about even and from twenty mailboxes Warmy costs less and does more. You can also try Warmy free for 7 days without a card. MailReach has no free trial for warm-up but its spam test is free three times a day.

MailReach vs Warmy: Common Claims, Fact-Checked

Comparison pages from both vendors and from third-party blogs don't always agree. Here's how the most common claims hold up against what each vendor publishes itself, checked November 2026.

  • Claim you may see
    "Warmy requires a demo before you can start."
    What we found
    No. You sign up and connect a mailbox yourself. The 7-day trial needs no credit card; demos are optional.
  • Claim you may see
    "Warmy uses custom, demo-based pricing."
    What we found
    Warmy publishes five self-serve plans from $49 to $429 a month on its pricing page. Custom plans are only for volumes above that.
  • Claim you may see
    "Warmy has limited or no inbox placement tests."
    What we found
    Every Warmy plan includes 5–50 placement tests a month, plus a 500,000+ US seed list.
  • Claim you may see
    "Warmy is built for B2C senders."
    What we found
    Warmy runs separate B2B and B2C warm-up networks. B2B senders warm up with real Google Workspace and Microsoft 365 mailboxes.
  • Claim you may see
    "Warmy prices per inbox."
    What we found
    Warmy prices by daily warm-up volume, so several mailboxes can share one plan.

    "100 warm-up emails a day is double what Warmy offers."
    What we found
    Warmy plans range from 100 to 5,000 warm-up emails a day. MailReach caps each mailbox at 100.

    "MailReach has no API."
    What we found
    Not true either. MailReach offers a Warm-up API and a Spam Test API.

How Warmy and MailReach Work in Practice

Email Warmup Process

Warmy email warmup runs through your existing provider on a protected network of over a million real Google Workspace and Microsoft 365 and consumer inboxes. It sends during working hours in the recipient's time zone and ramps up gradually and slows down at night and on weekends.

Warmy simulates natural engagement. It opens and replies and marks emails as important and rescues them from spam. You can choose warmup providers and use your own templates and topics in 30+ languages. Auto-archive keeps warmup messages out of your inbox.

How MailReach does it

MailReach warms up through a network of 30,000+ Google Workspace and Office 365 inboxes with an AI warming algorithm. MailReach warming runs on Autopilot by default and there's a manual mode for advanced users at up to 100 emails a day per mailbox.

Using Seed Lists

Warmy adds a 500,000+ US seed list across Gmail, Outlook, Yahoo and corporate and regional providers, including mobile seeds on real US devices. You send your campaigns to the list and the seed accounts open emails and move them out of spam and scroll and click links. Together with peer-to-peer warmup this warms new mailboxes and domains much faster than warmup alone.

How MailReach does it

MailReach's seed inboxes live inside its spam tests (30+ inboxes per test). They show where a test email lands but they don't engage with your real campaigns.

Authentication and Sender Reputation

Start with authentication. SPF and DKIM and DMARC are the core protocols in Google's sender requirements. Warmy's DMARC monitoring shows who is sending as your domain and what fails and the exact record to change. Free SPF and DMARC generators make correct records in minutes and the reputation tracker watches your domains and IPs and sends alerts when a signal drops.

How MailReach does it

MailReach checks SPF and DKIM and DMARC and blacklists and reverse DNS in its health checks and shows a reputation score for each mailbox.

Measuring Results

Warmy's placement tests run outside the warmup network and break results down by provider and show inbox and Promotions and spam. Scheduled auto-tests keep a fresh baseline. Keep the template and provider mix the same between tests. If most of your recipients use Microsoft 365 watch those results before raising volume even when the overall score looks healthy.

How MailReach does it

The MailReach spam test scores where a test email lands across 30+ inboxes and it can run automatically with Slack or webhook alerts. Each test uses one credit.

Free Testing Tools

Both vendors let you test for free. MailReach's free spam test allows three tests every 24 hours without an account. Warmy's free Email Deliverability Test checks placement and authentication and blacklists and Warmy also publishes 25+ other free tools, from SPF and DKIM and DMARC and BIMI generators to warm-up and mailbox calculators.

API and Integrations

Both tools have an API. The MailReach API covers warm-up and spam testing. Warmy's documented API exposes every feature and connects to n8n and Zapier and Make and it powers the warm-up inside other outreach platforms and ESPs.

Onboarding and Support

Both are self-serve. MailReach lets you bulk-connect Google Workspace accounts and G2 reviewers often mention its quick support replies. Warmy connects through OAuth or SMTP/IMAP and adds 24/7 human support and VIP channels in Slack and WhatsApp and Teams and a dedicated deliverability expert.

PRICING

MailReach vs Warmy Pricing

How to Switch from MailReach to Warmy

  1. Start a 7-day trial and connect your mailboxes through OAuth or SMTP/IMAP. No card needed.

  2. Run a baseline placement test so you know where each mailbox lands before the switch.

  3. Move one mailbox at a time. Pause MailReach warm-up on a mailbox before you turn on Warmy for it so it never gets two warm-up streams at once.

  4. Compare after two weeks. Run the same test again and check placement by provider.
