I have a large legitimate email list and want to start sending a newsletter.
I am concerned that my domain name may be blacklisted for sending spam (even though my list is legitimate and fully opted-in) and have an effect on my day to day email.
if I use a sub-domain of my domain, ie newsletter.domain.com and this was blacklisted, would it effetc my main domain as well.
Sorry if posting in the wrong forum, not sure if this was a hosting, email or domain question!
I do not think so. I suppose that would be better to test that to make sure.
As far as I know (and a google search seems to confirm this) e-mail blacklisting is done on an IP basis, not on a domain basis.
Meaning that if you’re added to the blacklist each and every domain (including subdomains) on the server will be blacklisted.
No domain name will not be blacklisted. I assume your subdomain name was blacklisted because of black hat SEO?
For SEO issues: domain names are being blacklisted.
For Email: IPs of the mail servers. Not IP of your web site is getting blacklisted.
sub-domain blacklisting will black list domain and may block IP as well.
Secondly, if you are on a shared platform, your host may not allow you sending so many emails at a time and will terminate your account.
