Verified form submissions never arrive to ANY email

Here’s the website: https://serene-beignet-c9fb02.netlify.app/

Form submissions appear as VERIFIED in the dashboard, but email notifications are not delivered to ANY recipient - I’ve tried several Gmail addresses and an unrelated domain address. It’s not an email provider issue.

Nothing arrives, including spam. It worked until I added a custom domain and switched the domain to Netlify DNS. Maybe related but maybe not.

Is anything being bounced or suppressed? Could support take a look at the internal logs?

Thank you

Welp, all of them came at once, after a few hours. Guess it was a server-side issue.
