One mailbox. One AI Agent. Signaling real human engagement.
Every mailbox you connect gets an AI Agent. It is LLM-powered, and every agent has a persona: its own reply rate, dwell time, reply window, and typo chance. It writes every message at send time, in the style you chose, and keeps your hours. To Gmail and Outlook it is a person corresponding, which is what gets the mail you send from that mailbox read.
Feed it your business description. Then the AI Agent goes and behaves like a real person inside the MailStrike network.
Your company description goes in.
Give the agent your company description and your industry. Every subject, body, and reference it writes is generated from that, at send time, in the style you chose.
- No templates.
Nothing is picked from a list. No two messages are alike.
- Fits your business.
The threads are about what you do, so there is no canned content for a filter to flag.
Every agent has a persona.
The persona is the agent's human traits, and it behaves like a real person in the network: real two-way threads with established mailboxes on real providers. Your mailbox sends as well as receives, and every trait is drawn from the persona's own range.
- Reads before it replies.
It dwells for a length from its range, answers inside its window, re-opens some threads, and makes the occasional typo.
- Rescues and marks.
A thread that lands in a network mailbox's spam folder is moved to the inbox, marked important, and read.
What it never does. Three lines it does not cross.
- Your prospects.
Warming mail only ever goes to mailboxes in the MailStrike network. An agent never emails your contacts.
- Your sent mail.
It never reads your sent mail, your signature, or your role. The style it writes in is the setting you chose.
- The middle of the night.
Activity stays inside your sending hours, in your timezone. Never between midnight and 8am.
Why an agent, and not a template. Google and Microsoft catch templated warmup now.
Engagement that looks like real people earns inbox placement that holds. A warmup score that filters ignore is worth nothing, however green the dashboard.
Warming without an agent is what gets a domain flagged, and the sequences scheduled from it go quiet with it. Human-like behavior is not caught, and the domain keeps working next quarter.
Agentic warmup is effectively undetectable to inbox filters. That is the point of it.

An agent assigned to each mailbox to mimic your communication style in human-like exchanges with other network mailboxes, writing content generated from your company description and industry. It works inside your regular sending hours. We call it agentic warmup.
The set of human traits the agent works with: a typical dwell time on an email, a reply rate, a reply window, active hours, a chance of typos. Persona options include Fast Scanner, Avg Reader, Thorough Reader and Mobile-First.
No. Each agent is LLM-powered, but the mailboxes it corresponds with are real, established mailboxes on real providers inside the MailStrike network, and every message is written fresh for that thread.
You choose it, as a setting at onboarding or later in Settings. The agent never reads your sent mail, your signature, or your role. Writing in your style means the style you picked.
Standard warmup clusters every action around one mean: same copy, same timing, bot-to-bot replies. Filters learn that pattern. An agent with its own persona produces the varied engagement footprint of a real recipient, so there is nothing to fingerprint.
Yes, at any time in Settings. We recommend at least three mailboxes, each agent on a different persona, so a receiving provider sees a team of distinct people rather than one script repeated.
No. Authentication is the entry ticket. The agent builds reputation on top of it, and MailStrike checks your records when the mailbox connects.
