TRANSACTIONAL EMAIL FOR AI AGENTS
Give your AI agents the ability to send transactional plain-text emails — with a subject line, a recipient name, and full delivery tracking — without building or operating an email backend.
Welcome emails
Send personalized welcome messages with a recipient name and clear subject line as soon as a user signs up.
Order confirmations
Automatically confirm purchases with trackable delivery status so you know the message reached the inbox.
Password resets
Handle account security notifications with plain-text emails that pass spam filters and reach users fast.
AI-generated digests
Send daily or weekly summaries composed by your AI, complete with a relevant subject line, on a regular schedule.
