The problem it solves

Your team wastes time manually checking whether an email address is valid before sending an important message or adding it to a list. Bad addresses bounce, waste outreach effort, and are easy to miss until it's too late.

Who it fits

A sales, support, or operations team that needs to confirm email addresses are real before using them.

How it works

  1. Someone types a slash command in Slack with the email address to check.
  2. Slack confirms the request right away while the check runs in the background.
  3. An AI agent checks the address's syntax, deliverability, and validity.
  4. A follow-up message posts back to the same conversation with the verdict and a short explanation.
What you get

A quick answer instead of guessing

Anyone on your team can type an email into Slack and get an instant, AI-checked verdict on whether it's real and deliverable.

What you get

A Slack message with a clear verdict on whether an email address is valid and deliverable.

What you need

A Slack workspace with a slash command set up, an OpenAI account, and a verify-email.app API key.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
