Configuring your own SMTP server is an add-on feature. Contact Zuora Sales if you are interested in purchasing it.

You can use your own SMTP server to send email notifications instead of using Zuora's default email server. The benefits for using your own SMTP server include:

  • More control over emails delivered to your customers because messages are sent through your own server
  • Ability to access sent email records through your SMTP server logs
  • No need to whitelist Zuora email servers because messages are sent through your own server

Zuora recommends systems like Pendula (Zuora partner), Amazon SES, Sendgrid, MailJet or Zuora's provided email relay solution that offer larger throughputs on email relay. If you use Google or Microsoft email relay service, you might reach their service limits with Zuora's bulk invoice, payment and account statement processed notification events. Please refer to Gmail sending limits and Microsoft 365 message rate limits and throttling for details.

Prerequisites

  • Ensure that a valid email address is entered in the Email field in your tenant profile (Administration Settings > Manage Tenant Profile). The email address is used as the mail.from value for notifications. The Email field cannot be blank or an error results.
  • Make sure your SMTP server relay feature is turned on. Otherwise, any emails sent with with a mail.from address in the notification that is different from your SMTP server default will fail.

Configure Your SMTP Server

  1. Navigate to Administration Settings > External SMTP.

    Example SMTP Server Configuration
  2. Click edit in the External SMTP Server Configuration Settings section and complete the configuration fields.
  3. Click test connection and save when the fields are complete.
    The data is saved if the connection is successful. If an error occurs, the configuration information is not valid and an error message appears.
  4. Click edit in the first section of the page, and select External SMTP Server.
