Email Mass mails with newsletter on own nameservers or not?

For me I always use 3rd party DNS nameservers for reliability and uptime and ease of setup. I use DNSMadeEasy.

But doesn't have a direct bearing on mass emails and deliverability. For that, it's a matter of having proper DNS SPF records, reverse PTR etc and that can be done via local or 3rd party DNS + a good mail/IP reputation (i.e. no having IP on spam blacklists - not sending too many emails simultaneously etc). Easier on 3rd party DNS namesevers though.

 

dns has nothing to do with email limits, that is mail server which is either locally hosted email server or via 3rd party mail servers via Sendgrid.com or Mandrill.com for newsletters or 3rd party smtp mail which has limits like ones mentioned at Email - Free @yourdomain.com Email Accounts & Alternatives | Centmin Mod Community

 

All have limits as you're no meant to send all at the same time but staggered approach for best deliverability apparently see Mandrill Support : Reputation System Basics and Mandrill Support : Reputation System Basics
