Overview

Email notifications from your own software

Transactional emails are the messages customers expect: OTPs, sign-up confirmations, invoices, receipts and order updates. Our transactional email service sends them reliably through an email API or standard SMTP settings.

Use the API for modern apps and the SMTP server details for any software that already supports SMTP, such as WordPress, CRMs or ERPs. For critical alerts, pair email with an SMS from the same account.
