I have a project which requires a form to promote an event. The form needs to have fields for the submitter to provide details (name and email address) of up 10 friends to receive an email about the event. The user notification email will work nicely for this, but it would need to be customised and I can see the gform_autoresponder_email filter would allow me to send the email to addresses defined in the form.
My question is can this filter (or another filter) be used to alter the content of the notification email according to the friend's details? Specifically to have "Dear [Friendname]" at the start of the email.
If there is a suitable filter I can use then this plugin will be ideal for the project.
Many thanks for your help,
