I used Protonmail in the past because of its "displayed name" feauture whidh showed "sent from: Instagram" to the recipient. Nowadays though protonmail doesn't allow you to make an email with the words "instagram" "snapchat" "support" etc and even if you manage to bypass that it immediately bans you when you send an email that looks like phishing. So what service should i use now that has similar features?

Uhhh, dude I don't think discussion of phishing is allowed here. But in terms of servers that usually have access to "large amounts of sendmail" I'd consider just buying a VPS for 5-6 bucks though some providers block port 25, and 2525 due to sendmail abuse.

That should cover spam.
