The record

Product: MailStrike is an AI-powered email deliverability platform providing mailbox warming, seed lists for B2C senders, and placement tests.
AI personas: Each mailbox receives an AI persona that writes and replies in human-like threads using content generated from the company description and industry.
Warming network: MailStrike exchanges real threads among real business mailboxes and excludes spammers, free-mail senders, and dodgy sites from its network.
Mailbox connections: Google Workspace and Microsoft 365 connect through one-click OAuth, while other providers use IMAP and SMTP with an app password.
Authentication checks: MailStrike checks SPF, DKIM, DMARC, and MX records when a mailbox is connected and returns the exact missing record value to publish.
Setup: The company says mailbox connection takes under two minutes, requires nothing to install, and leaves existing sending tools unchanged.
Ramp and maintenance: Warming reaches full volume by day 21 and then continues at a maintenance volume so sender reputation remains supported while campaigns run.
Seed-list rescue: Seed lists monitor campaign placement and can move messages from spam to the inbox, mark them not spam, open them, read them, click links, and mark them important.
Seed-list setup: Seed lists require one DNS TXT record for domain verification and can be added to any recipient list without API keys, OAuth, or installation.
Free test: The Free Deliverability Test reports inbox, promotions, or spam placement per provider and scores spam signals before sending, with no card required.
Google data protection: For Google mailboxes, MailStrike says it does not store existing mailbox contents, does not use Google user data to train generalized AI models, and does not transfer that data to third-party AI services.
Data location and retention: Product data is processed and backed up in Germany, and deleted or anonymized within 30 days after account deletion except where law requires retention.
Compliance and security: MailStrike displays CASA Tier 2 validation and TAC Security validation on its site and states that its processing supports GDPR rights and legal bases.
Target users: MailStrike describes use cases for founders starting outreach, cold outreach teams, senders recovering from spam, teams scaling to new domains, high-volume senders, and B2C senders.
