B2B emails conversion - mobile vs desktop ?

Hello,

I have a question regarding our society today :

A lot of surveys claim that more and more people are reading emails on their mobile. And B2C consumers tends to prefer buying through their mobile.
No doubt about that !

However, for a B2B brand, I couldn't find any survey analyzing the conversion rate between email read on a mobile device versus a desktop...

I want to believe that most B2B prospects would buy or clicks through their desktop instead of their mobile. Maybe I am wrong.

Do you know if any survey exist ?

What is your opinion on this topic ?

If any of you have ever conducted analysis regarding that, would you mind sharing some generic trends ?

Best regards,

Maxime
