FAQ's (These may be helpful AFTER installation): https://dynasend.com/pages/email-signature-user-faqs.html
MAC USERS - THE SAFARI BROWSER CANNOT BE USED
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:
In the installation window, just drag the Chrome/Firefox icon onto the Application folder. This will install the Chrome/Firefox browser.
Part 1 - Copying Your Signature to Your Clipboard
Note: If you don't currently have your signature open in a browser tab, display it now:
In the tab with your signature, press Ctrl-A then Ctrl-C - this will select your entire signature and then copy it to your clipboard.
Note: Mac users will use Command-A and Command-C.
Part 2 - Gmail Signature Setup Instructions
1. Sign into Gmail and click the GEAR icon and pull down to SETTINGS in the upper right.
2. Scroll down to the "SIGNATURE" section, click the bottom radio-button (little dot) to turn your signature on, then PASTE your signature into the edit window.
Note: If you want to input any of your own text in addition to the signature we've created for you, please type and format that text first, and then do your pasting of our signature as your last step. This will prevent you from accidentally damaging any of the hidden formatting code we use to activate links, etc. If you paste first, then use your keyboard to further modify the signature you risk damaging the hidden code. If this happens (you'll know because your links won't work), just start over from scratch.
3. Click SAVE CHANGES at the bottom of the page and you should be all set.
Note: Hyperlinks in email never work while you are composing or responding to a message. To test your links, compose a message to yourself, and try the links when you have received it and are reading it.
