Works with any assistant that supports remote MCP servers
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.
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

Log in with OAuth

Your team decides
