Letsignit Recommendations :
The image formats that are accepted on the designer are: png, jpeg, gif
The weight of the uploaded images must not exceed 500kb.
Good practice for signatures :
The recommendation proposed by Letsignit for signature images is between 100 and 300 px. This size gives you the guarantee of a quality rendering.
Good practice for campaigns :
The standard size proposed by Letsignit for campaign banners is : 600 pixels wide x 180 pixels high.
This size gives you the guarantee of a rendering adapted to the format of an email (without "cut image" for example).
