Which of these is NOT a best practice when optimizing your emails for mobile?
Make your content comprehensive. Since people carry their phones with them everywhere, a captive audience is more willing to read a longer email.
Use clear and concise messaging. People are more likely to scan emails, regardless of what device they are using.
Use a responsive template. That way your email will conform to the device your reader is using.
Bigger is better. When it comes to text, images, and calls-to-action, be aware that people will be reading your email on smaller screens.
