Some screenshots of my email reminder with templates for interval sending. The count of mails wich are ready to send is shown on a live tile.
You can choose the email addresses from a picker wich does show you all entries from the people hub with an email address.
The reminder pages will show the pictures of your people hub entries on your phone. The screenshots are without pictures. The pictures are not saved in the database of eMailAgent. Because they will be searched by the contact display name they will be removed if you change the reminder name in eMailAgent to a none existing contact name. If you change the name for example to group name like firefighters the picture will be removed. Since version 1.2 you can select more than one email address and you can edit the email fields and the reminder title.
