Hacked domain recovery that gets you sending again.
An attacker blasted spam under your name, and now filters treat every email you send as guilty. MailStrike assesses the damage, contains the abuse, and rebuilds your reputation until real mail lands again.
The cost of a compromise
One breach undoes years of sender trust.
Thousands of spam emails went out under your domain. Blacklists listed you, Google Postmaster dropped you to Bad, and now invoices, password resets, and sales mail land in spam or bounce outright.
A recovery plan that rebuilds trust.
Filters re-score senders on fresh evidence. MailStrike stops the abuse first, then fills the record with genuine positive engagement until Google, Microsoft, and the blacklist operators trust your domain again.

How MailStrike recovers a hacked domain
Real domains, real threads
Your domain trades genuine back-and-forth email with a network of real, established domains. That growing record of legitimate conversation is the evidence filters weigh against the spam the attacker sent.
Engages like a real human
Every exchange behaves the way people actually use email, down to the small tells filters watch hardest in a sender coming back from a flag.
Understanding
Re: Intro to MailStrike
Ramps from flagged to ready
Warmup volume starts low and climbs on a schedule providers accept from a recovering sender, rebuilding a clean record day by day until your score clears.
Daily volume
Together, these signals rebuild the reputation your domain lost, until Google and Microsoft trust it with the inbox again.
See how the personas workThe recovery, incident to ready.
Assess the damage
A blacklist scan across 21+ lists, a full SPF, DKIM, DMARC, and MX audit, and inbox-placement diagnostics. Within hours you know exactly what the attacker cost you: which lists flagged the domain, which records are broken, and where your legitimate mail is actually landing.
Contain the abuse
Compromised credentials get rotated, SPF is tightened so only your real senders pass, and DMARC is enforced so spoofed mail gets rejected outright. The spam stops going out under your name, which is the precondition every blacklist operator checks before delisting.
Re-warm the reputation
The persona warming network takes over: real inboxes on real domains receive your mail and respond with genuine opens, replies, spam rescues, and important-marks. Volume climbs on a controlled warmup ramp, and delisting requests go out once the clean record supports them.
Ready to send again
Reputation score above 90, three weeks of clean engagement, blacklists cleared. The dashboard flips to Ready. From here, placement monitoring and blacklist watch run continuously, so the next anomaly triggers an alert in hours instead of surfacing as a support ticket.
Every thread the personas exchange is written fresh by the LLM, grounded in your industry and company description. Nothing templated, nothing for filters to fingerprint. See how the personas work.
Size up the damage first.
Blacklist Checker
Scan your domain and IP against 21 major blacklists. A listing changes the recovery plan. Free, no signup.
Email Auth Checker
Audit SPF, DKIM, DMARC, and MX in one click. Weak records are how most compromises spread.

Hacked domain recovery questions.
How long does it take to recover a hacked email domain?
Plan for three to six weeks end to end. Containment is fast: credentials rotated and DMARC enforced within a day or two. Blacklist delisting usually clears within one to two weeks once the abuse stops. Reputation re-warming runs 21 days or more of clean engagement before the dashboard shows Ready to send again. Deeper damage takes longer, which is why the assessment comes first.
How do I know my domain was compromised?
The common tells: a sudden flood of bounce-backs for mail you never sent, customers reporting phishing from your address, a listing on Spamhaus or Barracuda, and Google Postmaster Tools dropping your domain reputation to Low or Bad. Run a blacklist scan and an SPF, DKIM, and DMARC audit first. Both are free and take under a minute.
Should I stop sending email while my domain recovers?
Pause everything you can. Every campaign sent from a flagged domain adds low-engagement evidence to exactly the record you are trying to repair. Critical transactional mail (invoices, password resets) can continue at minimal volume while the persona warming network rebuilds the reputation underneath it.
Wouldn't it be easier to just buy a new domain?
Rarely. Your customers, their filters, and their password managers all know your real domain. Abandoning it means re-earning trust from zero under a name nobody recognises, and it does nothing about the root cause, so the new domain risks being compromised the same way. Recover the domain, close the hole, and keep the brand.
Does MailStrike handle blacklist delisting?
Yes. The assessment scans your domain and IP against 21+ blacklists, including Spamhaus, Barracuda, and SORBS. Once the abuse is contained, delisting requests go out with the evidence operators want to see: the vulnerability closed, authentication enforced, and clean sending behaviour since the incident.
What stops the compromise from happening again?
The Contain phase closes the door: leaked credentials are rotated, SPF is tightened so only your real senders pass, and DMARC is enforced so spoofed mail gets rejected outright. After recovery, continuous placement monitoring and blacklist watch alert you at the first sign of new abuse, not weeks later.
Your domain could be sending again in weeks.
Assess the damage today. Recovery starts the moment the abuse stops.
