Certain TLDs/extensions are allowed to be registered for free. Examples include: .tk and .ml
Say for example, I register
somedomain.tk as my personal domain for email only.
I use Google Apps (for email hosting) and register:
What impact, with regards to being flagged for spam, will I experience for using a .tk or .ml or any other free domain extension?
Is spam only determined via IP address or do certain domain extensions (.tk , .ml , etc.) also carry with them negative-opinions from spam-engines?
