# MailFlash

> Send transactional messages from verified domains over SMTP or an API

MailFlash provides email delivery for applications that need to send receipts, password resets, account notifications and other transactional messages. Developers connect an existing application through an SMTP relay or a REST API, then use webhooks to receive delivery events. Activity logs give them a place to investigate what happened to a particular message.

The service groups plans by the number of sending domains and includes domain authentication with SPF, DKIM and DMARC. This gives a team running several small applications a way to manage their sending identities together while keeping each application’s own domain on its messages.
