You’ve created a signature with a logo, links and text formatting and it works great. So far so good...
Out of the blue, your great-looking email signature suddenly disappeared.
The reason is that you are replying to an email that is in Plain Text (TXT) format
No worries... it's easy to create an email signature in plain text.
Note: The plain text signature will not look the same as it does in HTML format. As the name suggests, Plain Text does not support any type of formatting.
