Heroku & DNS: Can http://nakeddomain.com target my heroku app?

Question

So, I read quite some content about this. The last of them here , and the heroku doc all .

In the end, no one answers the question clearly:

Is it possible to have http://nakeddomain.com aiming for the heroku app?

Here is what I know:

• It is easy to redirect http://nakeddomain.com to http://www.nakeddomain.com to CNAME http://myapp.herokuapp.com : I don't want to do this
• It is sometimes possible to use ANAME (or ALIAS or CNAME depending on the dictionary of the DNS provider) with the name APEX in another record. But in this case, all CNAMEd or ANAMEd records (even MX for mail delivery), which makes [e-mail] untested, are redirected to the heroku application, which, of course, does not process it by default.

So I'm going to reformulate

Is it possible to have http://nakeddomain.com to use the heroku app when using [e-mail] ?

• How? What services to use?
• How much does it cost if there are additional costs?
• CNAMing (Google Apps Sendgrid, qaru.site/questions/1366471/...), ?
