SMTP email integration

Retainza is provider-agnostic for email. Point it at any SMTP endpoint and it sends multipart HTML and text with rate-limit-aware throttling.

How it works

  1. 01

    Choose an SMTP provider, or use your own mail server.

  2. 02

    Add the host, port and credentials as an email connection in your project.

  3. 03

    Retainza verifies the connection with a test send before saving it.

  4. 04

    Build a template and send, or trigger it from an event.

Questions

Which SMTP providers work?

Any that speaks standard SMTP. SendGrid, Amazon SES and Postmark are common choices, and a self-hosted server works the same way.

Does Retainza mark up my email sending?

No. You are billed by your own provider at your own rate. Retainza never sits in the middle of your delivery cost.

Are emails sent as HTML or plain text?

Both, as a multipart message, so clients that refuse HTML still render something readable.
