Where they actually diverge
The cadence. Mailwarm caps you to a daily number. MailStrike works on monthly allocation, so the engine leans into days the network is engaging and eases off when it isn't. The monthly footprint is what receivers see; the daily metronome is a constraint, not a feature.
Who the mailboxes pretend to be. A second mailbox on the same domain warming the same way looks like one person with two accounts. MailStrike runs four personas (Fast Scanner, Avg Reader, Thorough Reader, Mobile-First), one assigned to each mailbox. Reply rates differ, dwell times differ, active hours differ. Three mailboxes on a domain, three personas: that looks like a team.
What the mailboxes write about. MailStrike generates warmup content using your industry and company description as prompt context, so a fintech sender's mail reads like fintech and a recruiter's reads like recruiting. Generic warmup copy is the giveaway that gives a lot of tools away.
What you get alongside. MailStrike publishes a free Auth Checker, Blacklist Checker, record generators, and a template analyser. These surface the DNS and content issues that quietly undermine warming. Mailwarm is warming.
