If you give out your professional email publicly like on business cards, expect spam arriving within 2-3 days since people will have you in their contact list and if they're hacked or caught up in chain-mail then you will be BCC'd into that chain mail or otherwise have your email in the hands of spammers.
For personal accounts, I've heard great things about SimpleLogin[0], AnonAddy[1], and Firefox Relay[2] to tackle spam. It's also worth having both a ProtonMail account & a Tutanota account if email privacy is a concern. Many services scan your email to target you with ADs, like Yahoo & Gmail, so avoid those if you can.
