MailReach vs Warmforge (2026): which should you pick?

Pick MailReach if

• Fits if you want warm-up and placement tests in one plan
• Works for agencies warming dozens of mailboxes, at $12.80 each from 51 billed yearly

Look elsewhere if

• Not for you if you want to try it before paying, as there's no free plan or trial
• Pricey if your team sends from lots of addresses, as each one needs its own warm-up
• Skip it if you need list cleaning, or DMARC managed rather than checked
• Tight if a campaign is due soon, as MailReach advises 14 days of warm-up first and keeping it running between sends
• Pricey if you pay monthly, at $25 a mailbox against $20 billed yearly

Pick Warmforge if

• Fits if you run a handful of outreach mailboxes and want warmup and placement tests in one place
• Works for Salesforge customers, who get unlimited slots

Look elsewhere if

• Not for you if you want to try warmup free first, since there is no trial
• Pricey if you run many mailboxes: every connected mailbox needs its own $10 slot
• Watch out: placement test plans are $32.50 to $140.80 a month on top of warmup
• Skip it if you want a mobile or desktop app, as it is web only
• Watch out: buy fewer slots than mailboxes and the rest get switched off

MailReach

• No free plan or free trial is listed; the free spam test is a one-off tool, not a plan.
• The vendor advises at least 14 days of warm-up before sending campaigns, and keeping it running between them.
• Each sending address under a domain needs its own warm-up, so costs grow with every mailbox.

Warmforge

• There is no free trial; mailbox slots must be bought to warm up, though you can sign up and run a free placement test.
• Placement test plans are sold separately from warmup slots, apart from 1 free test a month.
• If you buy fewer slots than mailboxes, the tool warms from the top of the list and disables the rest.
• The page says annual billing on mailboxes gives 2 months free, with no discount on domains.
