Hello,

What I could suggest here is using an SMTP for your website rather than plain mail.

That way you will be able to specify an SMTP server with authentication which your emails would be going through. You could for example use your GoDaddy SMTP settings. This would drastically increase the delivery rate of your emails as well compared to using plain PHP mail.

If you are using WordPress for example you could use a plugin. I’ve been using this plugin for a while now and it works very well: Easy WP SMTP

Hope that this helps!
Regards,
Bobby
