When an email is sent, each email client reinterprets and sometimes forces treatments that impact the style or other elements of the signature.

For the same signature, the rendering can therefore vary depending on the email client used for reception (Apple Mail, Gmail, Outlook, Samsung Mail, etc.) or even depending on the phone model (iOS, Android, Windows phone, etc.) if the email is read on a cell phone.

All these treatments that are applied therefore vary from one device to another and from one application to another and cannot be fixed by Letsignit (this problem is the same for any other software editor)

Most frequently observed changes

The style of the links in the signature is reworked

If your signature contains one or more hyperlinks (website, email address for example), the style of these links will very often be reinterpreted to be displayed in underlined and blue color (even if in the signature you had defined a non-underlined link without color). This is a behavior forced by email clients to make the element clickable.

The style of addresses or phone numbers is reworked

As with links, numbers in an address or phone number contained in a signature can be displayed in blue and underlined, this is a practice used to make the element clickable. Cell phones tend to make phone numbers clickable so that they can initiate a call.

The font displayed in the signature is not correct

The font used in the signature can sometimes also be transformed (fat, font, size)

Mail APP Mac

For example, a limitation is known with the font "Century Gothic" is not supported on Mail APP MAC. It will be changed to Arial.

On mobiles, font changes on reception seem to be systematic

The line spacing is not preserved

The line spacing is sometimes not kept between the different elements of the signature. This behavior seems to occur mostly on Gmail but can occur on other mail clients.


Receiving a signature on a cell phone

Mobile screens are smaller than on desktop (. If your signature is too wide for this screen size, the signature will be reprocessed to try to adapt the elements to the screen size.

An email client (Web or heavy) on a PC the display recommendation is 600 px wide for a signature

On a cell phone the display recommendation is 300px wide for a signature.

The signature will therefore be crushed and/or unreadable on a mobile screen if it is wider than 300px to try to fit the screen size.

Our best practices for a mobile friendly signature and a more qualitative experience:

- make a signature with a maximum width of 300px so that the rendering of the signature on mobile is not degraded. - Prefer the construction of a signature in "vertical" format, which generally provides a much more pleasant experience on mobile for the recipient.
