Ezoic Employee
Dvd Changing the SPF, MX or other email DNS records isn't something that'd send the site down.
In terms of the email delivery, I don't see any MX records in your Ezoic DNS settings right now are you able to locate those at your host? Missing MX records would typically cause email delivery issues, so this might also explain the issue at hand.
To fix this you want to add your MX records to Ezoic and the SPF record to Ezoic, I'd also suggest using the Ezoic recommended SPF value.
