Wrong domains or unpopular TLDs can harm email deliverability; use trusted domains similar to your main one.

There's currently a lot of discussion about the upcoming Google regulations and their impact on email deliverability.
However, I want to highlight that email compliance isn't the only factor affecting deliverability. Many of you use a "dedicated domain" for email marketing, and sometimes, choosing the wrong domain can lead to your emails being marked as spam.
To put it simply, every Top-Level Domain (TLD) carries its own reputation. If your dedicated marketing domain is on *.us, *.org, *.info or any other similar TLD, this could significantly impact your email deliverability. "Unpopular" TLDs are often used by scammers for phishing and spoofing attacks.
So, when developing an email marketing strategy, consider this and opt for a domain similar to your main one on *.com, instead of relying on *.info, *.online, or even *.homes.
But remember, they're definitely great for hosting your websites!
