There are cases in which your email client (Outlook, Apple mail, Gmail, etc.) and even the device you use (mobile phone or computer) will reinterpret the visual style of certain elements regardless of the style applied on Letsignit.

You can read an article here by Litmus, a marketing software for professionals that deal with emailing, in their article they explain why email clients display different styles.

Signature example as seen on the Letsignit designer:

Although the previous link explains in detail why the rendering of the siganture may differ when received, you should know that it may also differ when the message is edited. Again, the rendering capabilities of Outlook or other email clients can generate differences which will add to the variance we see in the end.

The items that are most often changed directly by the email client are email addresses, phone numbers, websites, or links. Normally on these elements a blue color or an underline is forced by the mail client.

Other elements such as the size of the text or even of images alignment according to the signature structure and leading are also sometimes reinterpreted by email clients.

Below you will find examples of the same signature displayed on different email clients and devices :
