Risks of Using a 3rd Level Domain for Email Campaigns

·Sep 16, 2025 12:31 PM·

Hey guys, look, if I run a campaign from 3rd level domain of my main domain, am I at any risk? I do no bad moves and it all looks just fine in terms of deliverability and hygiene in general, but just in case - if I burn subdomain.domain.com, will it burn domain.com, too? I heard different opinions on that, WDYT? Thanks much for any comments and help!

Hi Egor P. Using a subdomain is generally safe just don’t abuse it or the root domain could still take a small hit.
