Unfortunately when hosting with Godaddy, issues like this are pretty common place. For no rhyme or reason, email will just suddenly stop arriving even when no changes have been made. Then for no apparent reason, it will just start working. It is a quite a frustrating experience and we have also tried to bring this up with Godaddy support many times, but we just run into obstacles with their support as they provide no help with custom scripts. Unfortunately, because we cannot control their servers, there is little we can do here.
There are a few things you can try that sometimes fixes things:
1. Go to Settings > Email Notices and change the From: Field to the name of your E-Mail element in the form. To find this name click on the E-Mail element in your form and click the properties tab. Take note of the Name element. This is what you need to enter into the From field. You want to place it in brackets like this [email1]. Your setup looks like this:
2. Check your SPAM folder. Sometimes emails can get trapped there.
3. Try using different email address under the Settings > Email Notices Tab. Use Gmail, Yahoo, MSN etc.
4. Use S-Drive or find another hosting provider for just your forms.
