Hi 👋🏻
It’s Thursday, and it’s a perfect day to talk about a newsletter mistake. It’s one of the key mistakes most newsletter operators make. Guess what? um…um…guess it?
Well, it’s Mobile optimisation.
80% people read newsletters on their phones. They are scrolling during lunch breaks, while commuting, before sleeping, or between meetings.
Why this mistake hurts more than people think
Most of the newsletter operators only focus on the desktop view of emails.
Problems I see:
Huge paragraphs
Tiny fonts
Overloading the layout with visuals
Buttons that are not properly visible
And your readers close the email and move on to the next one in their inbox.
Your readers should feel at ease reading your stuff. If you cause a problem, they will not read it, your loss.
Attention
Attention spans are already short. And a poor mobile experience shortens them even more.
If the first few seconds are overwhelming, readers leave before your message even lands.
That is why readability matters so much.
Cleaner spacing improves flow.
Shorter paragraphs make reading easier.
Clear structure helps readers understand what matters most.
Do this before sending
Send a test email to your own email. Read it as a subscriber would.
Notice how quickly the core message becomes clear. Look at the paragraph length. Check whether the call to action stands out naturally.
If reading your own newsletter feels tiring, your audience probably feels the same way.
Mobile optimisation is about experience
Many newsletters struggle with engagement and assume the writing is the problem. Sometimes the issue has nothing to do with content quality. The experience itself pushes readers away.
And mobile experience sits right at the centre of it.
Before sending your next newsletter, check how it feels on mobile first. Your audience is already reading it there.
Did you like it?
Never ever take mobile optimisation lightly. It’s crucial, very, very crucial.
Hope it was helpful! Thanks for reading! See you soon!
