It could happen that your e-mail address is on the suppression list.
May I ask if the email address onto which you’re not receiving verification emails is the same for your Community account and Cloudflare account, or you’re using a different one? I advise not to share it here in a reply, just to confirm. Thank you.
May I also ask if you’re successfully receiving other emails from Cloudflare to this particular e-mail address?
In the meantine, just to be sure please make sure you allow all emails from [email protected] and [email protected] to prevent any issue.
