REQUIRED BROWSER FOR POSTBOX INSTALLATION
To properly support an HTML email signature, the Safari web browser cannot be used for your signature installation. The formatting will turn out wrong if Safari is used to open and copy the signature.

Please download and install either Chrome or Firefox before installing your signature. Download pages for each are here:

Chrome free download - https://www.google.com/intl/en/chrome/browser/desktop/index.html
Firefox free download - https://www.mozilla.org/en-US/firefox/new/

Notes for installing Chrome and Firefox:

Clicking the above links will take you to the Chrome or Firefox download page. Click the blue DOWNLOAD button. An installation file will download to your Apple download folder. They will appear as disk image thumbnails:

Double clicking the Chrome/Firefox thumbnail will open the installation window:

POSTBOX EMAIL SIGNATURE INSTALLATION INSTRUCTIONS

Note: Installing an email signature in Postbox requires pasting the HTML (computer) code itself - we will not be copying and pasting the signature itself. The first three steps of these instructions explain how to copy this compute code to your computer's clipboard.

PART 1 - COPYING THE EMAIL SIGNATURE HTML CODE TO YOUR COMPUTER'S CLIPBOARD

To If you don't currently have your signature open in a browser tab, display it now: enter your email address and then click the "Click to Display" button

  

Now go to the tab that is displaying your signature and RIGHT click on the window's white space beneath the signature and select "View Page Source" (see below).

When you go to compose a message you should new see your signature. Please note, the gridlines will be visible while you compose your messages. The gridlines will not appear to the recipient when they have received and are reading your message. They may appear temporarily when the recipient clicks reply and is writing back to you. All email has two modes - "compose mode" and "read mode" and they behave quite differently from one another at times (see below).

One final note: Any clickable hyperlinks in your email signature will not work while in "compose mode" but should work properly when your message has been received and is being read.
