By using the Edit template - Images and Text can be added to any template that you want to use for your mail out. 

Postback is a database driven mail system allowing the user to add "dynamic fields" from the database to the email template.  In this way each email is personalised with the clients name, address, company name and any other information that is residing on the database.  Even the Email Subject Line and REPLY TO: address can be personalised for each email that is sent.

Hyperlinks and Tooltips can be added to any images used in your email or normal text links can be used to return the email recipient to your website. 

Any amount of text or any number of images can be added to your email template including file attachments, sound or video/multimedia files.  

Postback also allows the user to add an unsubscribe link
