How to setup an email signature in Mailbox by Dropbox on OSX
Create and customize your Mailbox on OSX (by Dropbox) email signature using Email Signature Rescue. Once you have created your Mailbox email signature simply follow the steps below to have it set-up in Mailbox on OSX within minutes.
Before you start
You need to login to your Email Signature Rescue account using either the Google Chrome Browser (download it here) or Mozilla Firefox Browser (download it here). You cannot install your signature by copying it from the Apple Safari browser, as this will result in errors.
Login to your Email Signature Rescue account and click edit on the email signature you are setting up. Once you are in edit mode, click on the full screen preview button to open your email signature in a full screen view.
Once the Email Signature is open in your web browser, press Command + A to highlight the signature, then press Command + C to copy the signature.
Important: Do not use your mouse to select the area, only use Command + A, as you may miss out on grabbing some of the code that is needed.
Open Mailbox on OSX.
Once Mailbox is open, go to the top menu and click Mailbox (Beta) > Preferences.
Under the Account sub-heading, you will see a Signature box where you can paste your signature. Click into the box and press Command + V to paste your signature. Close the box when you're done.
Now compose an email. You will see your signature on the email unless you choose to show it. You can show and hide your signature by pressing the three grey dots that appear at the bottom of the email.
Congratulations! You will now see your brand spanking new email signature when sending emails with Mailbox on OSX.
