The Verdict column says who is better on each row and why; a check marks that side, both sides where the two are level. “No” means TrulyInbox's own public material documents no such feature at the time of writing; “—” means it is not documented either way.
MailStrike is the clear winner. Its AI-powered engagement is undetectable by Google and Microsoft, and it is designed specifically for email warming. TrulyInbox runs a chosen strategy with topic-level content, which is the pattern the providers detect, and its free plan lets anyone into the network, spammers and scammers included, so your mail is judged beside theirs. One caveat: if you need one of its 12 languages, or want a free plan first, TrulyInbox is the right tool. MailStrike warms in English.

Where they actually diverge
What the filters see. TrulyInbox's controls are real: industry-topic content, four strategies, your timezone, days and time windows. What it does not describe is any difference between one mailbox's behavior and the next. MailStrike gives every mailbox an AI persona with its own reply rate, dwell time, writing style and typo chance, and writes every thread from your company description rather than an industry category, in multi-turn conversations. On a multi-mailbox domain the filter sees a team of different people talking about your business, which is what makes the engagement effectively undetectable to inbox filters.
Readiness and rescue. Both dashboards tell you when a mailbox is ready for outreach, and both products document rescuing warming mail from spam and marking it important, so those rows are parity. MailStrike logs each rescue as an event in your live feed, and Flashman reads every inbox daily and tells you what matters, so you are not watching graphs.
What comes with it. TrulyInbox is warming, a free plan and a wide set of free generators and checkers. It documents no placement test and no seed lists. MailStrike includes placement tests on every plan (inbox, promotions or spam per provider in about three minutes), sells standalone Seed Lists for B2C senders, and carries Google OAuth verification with a CASA Tier 2 assessment.
Is MailStrike a TrulyInbox alternative?
A TrulyInbox alternative makes sense once you care who is in the network: a free plan lets anyone in, spammers and scammers included, and your reputation is measured beside theirs. TrulyInbox's controls are real (strategies, timezone, industry topics); MailStrike gives each mailbox its own AI persona and writes every thread from your company description, with placement tests included on every plan. If you warm in one of TrulyInbox's 12 languages, stay with it.
How to switch from TrulyInbox to MailStrike. Three steps, no downtime on your sending.
Connect the mailboxes to MailStrike
One-click OAuth for Google Workspace and Microsoft 365, no password shared; SMTP and IMAP for anything else. Each mailbox gets its AI persona on connection.
Hand over from TrulyInbox
Disconnect the mailbox from TrulyInbox once MailStrike's ramp is running, so the two warmers do not overlap; if you send with Saleshandy, keep sending with it.
Let the ramp run and prove the result
Flashman reads every inbox daily and tells you what matters, the dashboard shows Ready for outreach, and a placement test shows inbox, promotions or spam per provider.
Questions people ask about TrulyInbox and MailStrike
Is TrulyInbox made by Saleshandy?
Saleshandy's own help center describes TrulyInbox as a third-party warm-up partner included free in Saleshandy's paid plans, not as a Saleshandy product. Neither company's material states that Saleshandy owns it.
Does TrulyInbox rescue warmup emails from spam?
Yes, this is documented: TrulyInbox's network page describes marking spam-foldered messages as important and moving them to the inbox. MailStrike documents the same actions, each logged per event in the live feed.
Is TrulyInbox's free plan enough?
It gives one account 10 warmup emails a day with a reply rate up to 10%, per its pricing page. That is a way to see the product, not a ramp for a new domain. MailStrike's standard ramp reaches Ready for outreach by day 21 with an AI persona on every mailbox.
Can I run MailStrike alongside TrulyInbox?
You can, but two warmers on one mailbox double the warmup traffic without doubling the benefit. Pick one per mailbox, and let MailStrike run alongside whatever sends your campaigns, Saleshandy included.
Is MailStrike a good TrulyInbox alternative?
For English warming, yes: an AI persona per mailbox, threads written from your company description, placement tests on every plan, Seed Lists and Google OAuth verification. For warming in one of TrulyInbox's 12 languages, or for a free plan, TrulyInbox is the right tool.
Which is the better email warmup tool, TrulyInbox or MailStrike?
MailStrike on the warmup approach: a persona per mailbox against a chosen strategy with industry-topic content. TrulyInbox is better if you need one of its 12 languages, want a free plan first, or use it inside Saleshandy.
