I note that your mailto: links don't include an email address. e.g. at the bottom of the page https://www.forthepeople.com/class-action-lawyers/clergy-sex... the mailto link (black envelope image) has the email address "?".

It's an email share link. It's for you to share with whoever. All of those icons are social sharing icons.

? is actually for the query parameters and that's a properly-formed URI.

To be clear (since it wasn't to me; best tag-team approach to trick me into clicking some lawyer's website ever!): ...

The user is expected to click the email icon, then fill in the to: address, with the body pre-filled with the current url.

Most email urls passing query string parameters fill in the address (which winds up in the to:) and subject instead.

Absolutely follow you. Business decision, wasn't up to me ;)

That said though, best damn lawyer's site on the web, amirite?
