Switch across to your web browser and your Freshsales CRM account, then from the top right of your screen, click on your Profile icon and select Profile Settings.
From your Profile page you will see your User Details with your Email Signature field beneath that.
Click the Source button from the toolbar at the top left, then click inside the box and press Ctrl + V to paste your copied code.
Click the Source button again and you will see your email signature appear. It's likely that you may see some borders around your email signature, this is normal as it's the outline of the table and cells that hold your signature together. These lines will not show when you send your emails.
Click the Save button to the bottom right of your signature setting to save your changes. Your email signature will now automatically insert when sending emails within FreshSales.
