Unwanted delay in “verify your email” for some domains. The delay is usually ~10 minutes but we have observed +1h as well. For some email addresses, the email is received immediately.
- Use our own Email provider (Mandrill)
- email addresses that are experiencing delays are set up with G Suite (google) with a third-party DNS host.
- email contains html, css, link to image (static asset), link to our web app.

Does anyone have an idea?
Really appreciate the help as email-verification is required to access our app, making it a poor UX for our users.
Thanks in advance!
