They’re advising you to use a personal email that is tied more directly to your name or identity, like using Yahoo Mail, Outlook, or Gmail, which they view as more personalized.

If you’d like, you could try creating an email address with your actual name (or a variation) on one of the recommended services, like: yourname@gmail.com yourname@yahoo.com This should resolve the issue

Security professional here. This is legit a good call on their part. It’s because those types of addresses won’t bounce emails but aren’t necessarily in your control; it’s very, very easy to spam those petition forms with mail@ for a million real domains without bouncing the emails, making them seem legit.

You own your domain, obviously, so it’s really as simple as creating a forwarding/alias address of “changeorg@domain.tld”. If creating a forwarding/alias address is that much of a problem for you I suggest that you likely shouldn’t be hosting your own email in the first place.

Your laziness isn’t a good reason to be upset with a company taking steps to reduce their security overhead significantly
