Warmy vs MailReach: how each bills, what each tests and who should pick which

Warmy vs MailReach: the main difference

Both tools warm up mailboxes through a network of other inboxes and both test where mail lands, so the main difference is the bill and what surrounds the warm-up. Warmy sells plans that cover several mailboxes and size them by daily warm-up volume. MailReach charges per mailbox and sells spam tests as credits.

Side by side: what each vendor's pages state

• Billing: Warmy has B2B, B2C and custom plan tabs covering multiple mailboxes. MailReach prices per mailbox with monthly or annual billing, and asks for a custom quote at 100 or more mailboxes.
• Warm-up volume: Warmy's comparison page lists 100 to 5,000 warm-up emails a day by plan. MailReach lists up to 100 emails a day per mailbox.
• Network size: Warmy says over 1 million mailboxes, and its help center gives a floor of 300,000. MailReach says 30,000+ Google Workspace and Office 365 inboxes.
• Placement testing: Warmy lists 5 to 50 tests a month by tier on its comparison page, while its pricing page says to confirm the allowance. MailReach includes at least 20 spam test credits with its warm-up plan and sells more.
• Authentication tools: both check SPF, DKIM and DMARC. Warmy adds DMARC monitoring and report analysis. MailReach lists blacklist and reverse DNS checks.
• Extras: Warmy lists email verification, an API and a seven-day trial. MailReach's home page describes an email verifier and a co-pilot that suggests fixes.

Where the vendors disagree about each other

Each vendor wrote a page that favors itself. Warmy's comparison table says email verification is not listed for MailReach, yet MailReach's home page describes an email verifier. Warmy's table says MailReach's network size is not disclosed on its pricing page, while MailReach's how-it-works page states 30,000+ inboxes.

MailReach's page argues that Warmy's topic and language options do not build reputation. Warmy's page argues that its seed list and larger network speed up warm-up. Both are sales positions from the vendors, so compare the features you need on each pricing page instead.

Which to choose

• Choose Warmy if you manage many mailboxes or client domains and want one plan with placement tests, DMARC monitoring, verification and a named contact.
• Choose MailReach if you warm a handful of mailboxes and prefer a per-mailbox bill. Its own pages describe it as built for B2B senders.
• Choose the warm-up bundled in an outreach platform if you already pay for one.
• Choose neither yet if SPF, DKIM or DMARC fail or your spam rate is high. Warmy's calculator page says warm-up cannot fix those, and MailReach says senders who have stayed under about 20 cold emails a day per inbox might not need warm-up.

Questions to ask both vendors before you pay

• What placement test allowance comes with my plan, and what happens when it runs out?
• How many mailboxes and warm-up emails a day does my plan cover, and what happens at the limit?
• What do I lose if I cancel mid-cycle? Warmy's terms say fees are non-refundable and cancellation takes effect at the end of the billing cycle.
• Does the network's provider mix match my recipients: Google Workspace and Microsoft 365 for B2B, Gmail, Yahoo and Outlook for consumers?
