Third party configurations

Talo uses a handful of third party services to handle common tasks.


Sentry is an error-reporting tool that alerts you when exceptions get thrown. You can enable Sentry by setting the SENTRY_DSN environment variable to your unique DSN.


Talo uses Sendgrid to send emails. It handles common problems with running your mail server like handling reputation, bounces and more. You can enable emails by setting the SENDGRID_KEY environment variable to a valid API key.


Make sure your API key has full access to Mail Send and Sender Authentication. Your domain must also be authenticated within Sendgrid.
