+:::tip EU data residency
+If you use a SendGrid API key created on the <ExternalLink to="https://app.eu.sendgrid.com" text="EU portal (app.eu.sendgrid.com)"/>, set `region: 'eu'` in `providerOptions`. EU API keys only work against the EU endpoint (`https://api.eu.sendgrid.com`); without this option, email delivery will fail with an `Unauthorized` error.

 :::note Notes
 
 * When using a different provider per environment, specify the correct configuration in `/config/env/${yourEnvironment}/plugins.js|ts` (see [Environments](/cms/configurations/environment)).
