Generally speaking, it isn't a good idea to publish your email address on a public forum. I recommend keeping the initial contact through a PM; later you can exchange personal email addresses privately if you wish.
My email is listed on my profile ( may be a xxc@ yah oo. com but it's there). Other than bots grabbing it no reason not to list an email.
An email address that has been used for years and is easily tracked across all forums makes me feel better about dealing with people.
A landline is really nice also.
And the PM function here does seem to hit my email and has ( barring upgrade timeouts ) always worked flawlessly for me.
This "PM" thing is newer to me. Buying or selling I like using all three contact methods -maybe not for a tin of pellets or such but- I will send a PM explaining intent & give email and phone and follow up final deal in writting-email-.
