Suddenly Welcome emails going to gmail spam, forget password goes to inbox

Hi

Been using zen-cart for well over a year but in the last few months we have been getting reposts from customers that use gmail (hotmail too) that their Welcome emails are going to gmail spam.

After a bit of testing I have found that the welcome mails are going to the spam, but password reminder emails are going to the inbox. I compared the headers of both emails and they are the same bar time stamp and message ID etc.

So It must be something in the text. We haven't change the welcome email in nearly a year, so i'm guessing it must be a recent change to the spam filter that has caused this.

Does and one know of a guide of what can cause the spam filters to be triggered or if there is a different reason i'm missing?

Thanks

have a look at this page: http://www.zen-cart.com/wiki/index.php/Troubleshoot_-_Email_Problems

It could be a number of things, if some emails are not treated as spam then sounds like you are lucky and your host is not blacklisted.

It is quite well known that gmail's filter is very aggressive, your best bet if you can't see anything wrong with the subject or body text in the message is just add notes on the page to ensure the user checks their junk mail box for your emails.
