Hi,
I am having a problem with the emails on website I did for someone. They have a list of customer to send prices list monthly, but the emails on most of them goes to the spam folder.

Email is very simple, with HTML text and one link. This is the email format:


From: [email protected]
to: [email protected]

Two lines of text here bla,bla,bla

link here (to www.senderdomain.com)


end of mail....

I know they can go to the spam and make it 'not spam', but out of 5k customers we don't know how many of them are getting it or not. Also WHY are they going to spam?

Thanks and any help will be appreciated!
