I have someone wanting to buy something off me via email.
They have contacted me several times, all of which I reply to.
After I have replied I do not hear from them again, until they write a similar email a month later say.
I am wondering if I am in the spam filter of there email system in which case they may think I am not replying.
Is there anyway to contact them so I know they will see it?
All I have is there email address.
