Should I be concerned about Email responses from my custom email being flagged as spam? - Lemmy.zip

Pops wants me to use my Gmail account for job postings… but I’ve already worked so hard on setting up my Email with Purelymail and a custom domain. I’ve never had an issue of my Email getting flagged as spam before, but in this instance I sent him a zip file with no message body and it was sent straight to spam. My question is: would you bother using Gmail just to ensure your Email replies to interested HR people don’t get sent to the spam bucket? In my opinion, the use of a custom email address indicates flair to potential hiring teams - because it shows that you are capable of setting that stuff up. BTW my TLD is Senegal (.sn) to phonetically match my last name (it’s a really cool email) but the actual name header displays as my full name just like any other email address would.
