Custom Email Provider

To send Authgear emails to end-users with your own domain, e.g. [email protected]. 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 [email protected], 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 [email protected].
Follow the instructions from the email service provider for setting up your domain:
