Okay, so similar issue to this question (Sprout email notifications - setting the recipient?). I must be doing something stupid here because. Trying to set the recipient from an entry form, with a hidden field:
<input type="hidden" name="recipient" value="{{ 'name@address.co.uk'|hash }}">
Then in the control panel, the Recipients field has {recipient}. That should work right, but I don't receive the email. If I manually set an email address in the control panel Recipients field, it works fine.
value="name@address.co.uk"
