Custom Email Provider

Optimize for email deliverability by using your own SMTP server to send Authgear Emails (such as forgot password, verifications) in your own domains.

To send Authgear emails to end-users with your own domain, e.g. [e-mail]. You will need to configure the external SMTP provider.

Authgear currently supports SendGrid and other custom SMTP Providers.

Send from an email address under your domain

The sender address can be configured by changing the value of theemail.default.sender key in the localization JSON. Go to Portal > Localization > Translations and add/change the value of email.default.sender to your own email address, for example [e-mail], and Save the settings. The value can be set separately for each locale.

Sender domain authentication

Before adding the email service provider to Authgear, make sure the sender domain is verified and authenticated on the email service. For example, your domain myapp.com should be configured in your SendGrid account so Authgear can use the account to send emails with [e-mail].

Follow the instructions from the email service provider for setting up your domain:
