Integration details
Description
Lettermint is a European email service for transactional email and broadcast email. This plugin connects your Lettermint account to your AI assistant. Instead of clicking through projects and logs in the dashboard, you just ask. Why you'll use it A customer says their confirmation never arrived. You ask, and within seconds you know if it was delivered, bounced or is still on its way. Your marketer wants to know how the latest campaign did. You get the delivery numbers next to last month's. Not sure which route to use for a newsletter, or whether your domain is set up correctly? You ask for that too. What you can do - Look up a message and see if it was delivered, bounced or is still on its way - See which emails a project sent in a certain period - Check the health and DNS setup of a sending domain - View delivery statistics and plan usage, and compare periods - Manage projects, routes, sending domains, webhooks and suppressions - Send a test email or resend an existing message Privacy Transactional email often contains password resets, invoices and order details. That is why personal data in your emails is hidden from the assistant by default. It sees whether and how a message was delivered, but not what was in it or who it went to. Because sending needs a recipient address, sending email only works when this filtering is switched off. If your emails contain no personal data, for example newsletters, you can switch it off in your team settings. The assistant can then also see the content and send email for you. How access works You need a Lettermint account. You sign in with your own account, so there is no API key to paste. The assistant only reaches the teams and projects you already have access to, and your team can switch off access at any time.
