Hi there,

I have recently set up a site that requires simple verification by clicking on a link in an email sent to the user.

I've had a number of users that have complained this email has never arrived, although on further investigation I have found it has gone into their spam. It seems that 90% of email providers will not see this as valid email.

Are there any golden rules I might be breaking? I've really got no idea what kind of things I should be avoiding, so any help would be greatlly appreciated.

Many thanks in advance,
Jon.

A sample of the email, along with its headers would be helpful in solving this problem.
