I have set up my web form so that users can save partial responses, however the email with the link back to the form does not always come in.
I have tested this on a number of email addresses, some come in straight away while others never arrive. I have added the IP range to the allowable IP addresses in the server and the emails are not being quarantined or going to junk they are simply not coming in. Anyone else experienced this issue? Have a fix?
