Email for agents.

Give your agents email identities so they can truly work for you.

  1. Start on our domain

    Create your agent’s first inbox on an @extrovertmail.com address.

  2. Move to your domain

    Choose a dedicated subdomain like @agents.example.com. Your example.com website and your @example.com email stay exactly as they are.

  3. Or buy a new domain

    We’ll register it and set it up for strong deliverability and spoofing protection.

You’re the boss.

We keep you in the loop until your agents earn your trust. They learn from every edit you make.

Once your agents get it right every time, hand review off to a dedicated agent, or let your agents send on their own.

Agent · draft 1

Hi Dana! Circling back, hope your week's going well! I'd love to…

You

Cut the warm-up. Lead with what she gets. We never “circle back.”

Agent

rule savedoutreach follow-ups

Noted: value first, no warm-up, never “circle back.”

Agent · draft 2

Dana, your team hand-checks every export. We can stop that. Fifteen minutes?

You

Illustrative. Your agent judged the feedback reusable and saved a category rule; not every note becomes one. What you approve is exactly what goes out.

Different mail, different rules.

Give each category of mail its own rules, so every message matches your team's voice and requirements. Ban em dashes everywhere with a shared rule.

When to use

First touches and follow-ups.

Rules

  • lead with the value
  • no warm-up
  • never “circle back”

Example

Dana, your team hand-checks every export. We can stop that. Fifteen minutes?

When to use

Replies to your customers.

Rules

  • lead with the fix
  • one next step

Example

Fixed. The export cap was on our side and it's lifted. Reply here if anything else looks off.

When to use

Requests that reach you.

Rules

  • protect the calendar
  • name the terms

Example

Thanks for thinking of Ana. She takes a handful of stages a year and prioritizes events with sponsorship attached. If that's on the table, I'll find thirty minutes.

When to use

Mail to your own team.

Rules

  • no ceremony
  • link the runbook

Example

Heads up: tonight's deploy pushes standup to 9:30. Rollback plan is in the runbook.

A woman in a butter-yellow blouse waving from a sunlit café doorway, delighted to see someone. A man in a cream knit on the edge of a desk, one hand on his chest, laughing kindly. A woman in a butter-yellow suit walking onto a small stage, waving to the audience. A woman with cropped hair leaning on an office kitchen counter, a mug in both hands, laughing beside the espresso machine.

Your agents learn. Extrovert remembers.

Your agents notice the kinds of mail you send and turn your feedback into reusable rules. Agents in the same project share those rules automatically whenever they draft a message.

Example

  1. Your note Cut the warm-up. We never “circle back.”
  2. Rule saved outreach follow-ups never “circle back”
  3. Rule shared Every agent in the project follows the new rule on its outreach follow-ups.
  4. Drafts revised Follow-ups already waiting for your review are redrafted under the new rule. You never repeat yourself.
