#01mailwarm.com
Email warmup and deliverability system with a real-inbox network, inbox placement monitoring and expert support.
Verdict
Warmup alone stopped being enough a while ago. The placement monitoring and the expert call are why I'd look at 2.0.
#02themailx.com
SPF, DKIM, DMARC, blacklist and MX checks for humans, plus an MCP endpoint for AI agents.
Verdict
Free, no signup, and your agent can run the audit. Run it on every sending domain before a campaign goes live.
#03trulyinbox.com
Email warmup with DNS checks, spam rescue and inbox placement analytics.
Verdict
A cheaper warmup option for agencies with lots of mailboxes. Compare placement results, not warmup email counts.
#04mailreach.co
Email warmup and spam testing that builds sender reputation and checks inbox placement for cold mailboxes.
Verdict
Warmup plus placement tests in one place. Run a spam test before every new campaign, not after replies dry up.
#05glockapps.com
Deliverability toolkit with inbox placement tests, DMARC analytics and IP reputation monitoring.
Verdict
The placement test I trust to see where mail actually lands. Fix DMARC reports here before blaming copy.
#06scaledmail.com
Managed cold email inboxes on Google, Microsoft and SMTP, with DNS authentication and Slack support, ready to connect to your sequencer.
Verdict
ScaledMail sets up Google, Microsoft and SMTP inboxes and the DNS for you. Google is $3.50 a mailbox, Microsoft is $50 a domain, and I'd warm them in your sequencer for about two weeks.
#07mailveri.com
Pay-as-you-go bulk email verification and a real-time API that flags invalid, disposable, catch-all and role accounts.
Verdict
Credits never expire, and $9 buys 10,000 credits. Use the 1,000 free ones on a list you already know first, because the terms say a purchase is final.
