Letsignit has two different methods of inserting images into signatures, each of these methods can be selected for each of the different image blocks such as the logo, the profile picture, the image block but also the social networks and the campaigns.


These insertion methods are:

A) Image hosted on the web:

The image is hosted on a Letsignit server and this generates a URL which is used to download the image when the email is opened by the recipient.

The advantage of this method is that emails are less heavy because the image is not directly embedded in the body of the email. When forwarding or replying to the message once or several times, the images will never lose their quality since they will always be referenced to the server to display them again.

The downside is that if the recipient has blocked image downloading automatically from their messaging client like Outlook, the image will not be displayed until the recipient clicks "download image".


This behavior is used on images sent from webmail or from a mobile device.

This behavior is not compatible with using the Letsignit application for Outlook.

How to do it from the signature settings:

B) Image embedded in the email:

The image is directly embedded in the body of the email at the time of sending.

*There is a 500kb size limit for embedding and image.

This option is already used by the Letsignit app for Outlook.

This option is configurable for sending emails passing through the SMTP connector.

Advantage: Recipients automatically view the images contained in the email signature without having to do any extra action to download / view the images.

Disadvantage: By adding the images directly to the body of the email, the weight of each email that is sent increases. Depending on the messaging client, some images may appear as attachments due to the way each one treats the images. Images may lose quality when replying or forwarding email.
