MailerSend

The MailerSend connector lets Claude work directly with your MailerSend account so you can handle transactional email without leaving the conversation. Send email: Compose and send transactional emails — including HTML, plain text, CC/BCC, attachments, and template-based messages. Schedule messages for later, and list, inspect, or cancel scheduled sends. Domains: Add and configure sending domains, retrieve DNS records, trigger and check domain verification, and update domain settings. Templates: Browse, inspect, and delete email templates in your account. Analytics & activity: Pull delivery and engagement analytics broken down by date, country, and recipient client (user agent name and type). Review message history and recipient activity such as opens, clicks, bounces, and complaints. Email verification: Verify individual email addresses (synchronously or asynchronously) and run bulk verification lists to keep your sending lists clean. Webhooks: Create, list, inspect, update, and delete webhooks to wire MailerSend events into your own systems. Access is scoped to your own MailerSend account through a secure OAuth sign-in — the connector never sees or stores your API key. Just connect, authorize, and start managing your email in natural language.
