Thank you for your positive words!
The issue possibly relates to an issue linked with the mail setup on your account. I will ask a colleague to look into this.
However, I also note you’re not using an @quickfile.co.uk email address, like the default noreply address, to send your emails through the system.
If you got to Account Settings >> Routine Emails you have a warning there in a purple box.
An increasing number of email clients now reject mail from one address that is sent through a different server. In this case QuickFile is sending your mail but setting the “from address” as the one you’ve set on your account (which isn’t @quickfile.co.uk)
The simplest way to fix this is to click the “fix this for me link” in the error box. This then configures QuickFile to send your mail from an @quickfile.co.uk address.
If you really want to continue sending mail from your email address then you would need to configure QuickFile to send from your own mail server. You can find information on how to do this here.
This will also help you increase the reliability of your emails, and decrease the chances of them being rejected or going to spam too.
Please let me know if I can be of further assistance.
