# MailStrike > MailStrike (mailstrike.ai) is an email deliverability and sender reputation platform. Its two core products are managed AI email warming and seed lists: it builds, monitors, and recovers sender reputation so email lands in the inbox instead of spam. Each mailbox is warmed by its own dedicated AI persona, an LLM-powered agent with unique human traits, engaging in real two-way threads across a curated, vetted network (no self-serve signup, around 900 active customers as of August 2026). Seed lists give B2C senders per-provider inbox-or-spam placement data and rescue mail from spam during live campaigns. CASA Tier 2 security assessed (validated by TAC Security), Google OAuth verified, rated 4.9 on G2. Founded 2026, based in Poland, backed by IT Monks. Key facts (last verified 2026-08-24): Starter $18/mo billed annually ($22 monthly), Pro $45/mo billed annually ($54 monthly), Custom and Seed Lists quote-based. A standard warming ramp reaches an Inbox Reputation Score above 90 by day 21 on a clean account; results vary with domain history, providers, and list quality. Every customer starts with a demo call and gets guided onboarding. MailStrike is not a sending platform, cold email sequencer, CRM, or lead database; it works alongside those tools.
