"user does not exist (in reply to RCPT TO command)" when sending to custom domain

I have my domain registered through Namecheap. Everything looks good there:

https://toolbox.googleapps.com/apps/dig/#MX/gabeanzelini.com

https://toolbox.googleapps.com/apps/dig/#TXT/gabeanzelini.com

https://toolbox.googleapps.com/apps/dig/#CNAME/gabeanzelini.com

However, when I email myself from my iCloud or my wife's gmail, I get the following bounce-back:

SUBJECT:

Undelivered Mail Returned to Sender

BODY:

This is a system-generated message to inform you that your email could not

be delivered to one or more recipients. Details of the email and the error are as follows:

<THE EMAIL ADDRESS I AM SENDING TO>: host mx01.mail.icloud.com[17.57.152.9] said: 550 5.1.1

<**@****************>: user does not exist (in reply to RCPT TO command)

I contacted apple support and they said it was Namecheap's issue. I contacted them and they sent me those links and, comparing them to what I was told to enter, they match. I'm at a loss from here.
