Transactional email and SMS sending. Your client pastes their MailerSend key once, and your agent or your code works with their access.
Email
MailerSend is a transactional email and SMS service from the makers of MailerLite, built for developers sending receipts, alerts and notifications.
With your client's MailerSend connected, your agent or code can send transactional email and SMS from their account.

Building with MailerSend? The docs have setup steps and code for every tool.
Your agent calls any endpoint of MailerSend's API with the request tool, with the client's access attached.
