Mobile Design Guidelines from Emma Email Marketing
Emma, the EPS Astek sends all our emails out through, had a truly excellent round up of mobile-friendly-email design and programming guidelines. Really great nuts and bolts stuff for all of us. For the designers, things like recommended pixel sizes for links, fonts, email layout and landing pages widths and more. For the programmers, actual code snippets for forcing certain behaviors to keep emails and landing pages sized for readability and interaction.
