You can use special characters or symbols in your content. It is important to insert them using the Insert custom character feature in order for the symbols to be web-compatible. Otherwise, your characters could change depending on the email client.
To insert a special character:
1. Go to More>Insert
2. Click on “Special Characters”
3. Click on the character you wish to use and it will be inserted into the open section.
Once the character is inserted, you can modify its color, size, etc.
