How Wopie works with Lettr.

Wopie is an AI agent that works in Lettr for you. You ask in Slack or Microsoft Teams. It adds contacts to lists, builds segments, checks your sending domains and looks up emails you already sent. It can cancel a scheduled email on request. Anything that reaches customers or deletes data waits for a person's OK.
