I have a contact form on my website, which actually works :D The problem

  • 0

I have a contact form on my website, which actually works 😀
The problem is, that the email ends up in the spam folder. I have tried to do stuff with the header section, but nothing seems to work.

Can anyone help me with this?

thanks

    It has nothing to do with the PHP code but make sure that the email are being sent from a domain that is hosted on the server. That means it would be a bad idea to use your gmail address for sending though PHP. Every email that leaves the server needs to be signed and needs to have SPF records

    This is usually because in the DNS a correct SPF record has not been setup. This can be easily done depending on the software you use. If you use cPanel then this is pretty much a two step process.
