Use cases

Your assistant takes care of it

How did Tuesday's newsletter do? Is the new domain verified yet? You ask, your assistant looks it up in Lettermint.

Answer a customer right away

A customer asks whether their confirmation went out. Ask your assistant what happened to the email and reply straight away.

Campaign results

Your assistant puts the open and click rates of your latest newsletter next to last month's.

Send or schedule an email

Send a test email to yourself or schedule a message for tomorrow morning, without leaving the chat.

Set up a domain

Add a sending domain and ask which DNS records are still missing.

What happened to an email

Your assistant reads the delivery events and tells you, for example, that Gmail accepted the email after 4 seconds.

Search the documentation

Ask which SDK fits your stack or how to set up DKIM. Your assistant looks it up in our documentation.

Privacy

Personal data stays hidden from your assistant

Transactional emails contain password reset links, invoices and orders. Those don't belong in an AI chat. So your assistant only sees that an email went out and whether it arrived.

Only sending newsletters without personal data? Then your team can make the content visible in the team settings.

Personal data hidden by default

Senders, recipients, subjects and content stay out of view.

Log in with OAuth

No API token ends up in your assistant.

Your own permissions apply

Your assistant only reaches the teams and projects you can access.

Your team decides

Admins can switch MCP off for the whole team at once.
