The software gives you the ability to put a header at the top of all software created emails as well as a footer at the bottom of all software created emails. The header or footer you insert into the admin tool will be placed at the top and/or bottom of all emails your Geo software sends to all clients. You set the header and footer within the following admin tool settings:

EMAIL SETUP > GENERAL EMAIL SETTINGS > Site-Wide Email Header
EMAIL SETUP > GENERAL EMAIL SETTINGS > Site-Wide Email Footer  

Look to the following screenshot to where you'll find those configurations:

Simply typing in your header and footer text within the appropriate admin tool settings above may not get the exact results you wish. Hitting the return key within the textarea box does not put a newline or carriage return within the final result of email. But you can format these emails using raw html. Typing the following in the header:

this is the header's first line
this is the header's second line

Will result in the following within the actual email:

this is the header's first linethis is the header's second line

But you can get to two lines above on separate lines using an html br tag like so:

this is the header's first line<br>
this is the header's second line

The above yields this in the email sent:

this is the header's first line
this is the header's second line

We strongly suggest you stay simple within your emails. Many clients include html image tags within their header and footer that do work. But we do not suggest much more than the html img and br tags. You are running the strong risk of parts of your email's html being stripped along the way to it's destination or that your email doesn't make it at all. In other situations the email reader may simply ignore your html formatting leaving raw exposed html in the email. In the area of email formatting our advice is keeping it as simple as you can.
