Why people use MailSlurp
MailSlurp for automated email testing and QA workflows
This Connector changes that. You can tell your agent to handle the whole thing. It grabs a random inbox, triggers the email, waits for it to land, and grabs the data. You go from manual clicking to a single command.
What Vinkius changes
You get a fully automated way to test email flows without manual intervention.
Use it from Claude, ChatGPT, Cursor or another AI client you already have.
