When to Use a Mobile-First Email Signature Design

Consider switching to a mobile-first email signature design if most recipients open emails on mobile devices.

It’s risky to assume this without checking the data. While mobile usage continues to grow, many professionals still spend their day working on desktops. Business emails are often read in classic office environments on larger screens.

With Xink’s Email Client Statistics (available with Xink Campaign), you get valuable insights to support your decision-making.

This feature provides data on:

  • Device type – desktop vs. mobile
  • Email clients – New Outlook, Classic Outlook (Win),  Legacy Outlook (Mac), Apple Mail, Gmail, and more
  • Operating systems – Windows, macOS, iOS, Android

All data is presented in a clear, easy-to-understand format so you can quickly evaluate trends and adjust your signature strategy accordingly.


If the data shows a high volume of mobile opens, it’s time to consider a mobile-optimized signature.

But if most recipients still use desktops or Windows-based clients, wouldn’t you rather know before redesigning your layout?

How to Design a Mobile-Ready Email Signature

If your analytics confirm that most email opens happen on mobile devices, apply a mobile-first approach to your signature layout.

Recommended width: 320px

Use a 320px-wide table when designing your email signature. This ensures it fits neatly within the screen of most mobile devices.
