Our pick when you also need evidence: warming and a spam and placement tester share one login, and each mailbox comes with test credits.
From $19.50/mo · No free plan, paid per mailboxSee MailReachWhat each one actually does
Warmup Inbox is a standalone warmup service: it adds interactions from a network to build sender reputation, with daily warmup volumes set by plan. It does not test inbox placement or verify lists.
MailReach warms mailboxes and ships a spam and placement tester in the same product, so you can see where a seed email lands by provider and check SPF, DKIM and DMARC without a second subscription.
Price, side by side
Both tools bill per mailbox, so the real question is how many inboxes you run and whether you also want testing. For the full picture, see what email warmup really costs per mailbox and per client.

What the two products actually look like
Questions people also ask
Do I need a placement tester if I already warm my mailbox?
Warming builds reputation; a placement tester tells you whether it worked. If you want proof of where mail lands, MailReach includes that. With Warmup Inbox you would add a separate tester such as See GlockApps .
Is warmup enough to fix spam-folder placement?
Not always. Authentication errors, a poor list or content can send mail to spam regardless of warmup. Diagnose the cause before paying to warm.
