Activation emails
Welcome new customers the moment they create an account and let them set their communication preferences.
Transactional email that reaches inboxes at critical moments.
Sending system alerts to your contacts has never been safer. Password resets, receipts, and notifications — always delivered on time, with full tracking.
What exactly is transactional email?
A transactional email is sent to a single recipient to complete an expected transaction — it is triggered by the recipient's own action and contains information they want or need. When a user requests a password reset or places an order, a transactional email is sent. Because users specifically request this content, transactional emails have higher open rates and deliverability than marketing campaigns, which are one-to-many promotional messages. Use Message Streams to keep transactional traffic isolated from marketing sends.
