This is because they want to guarantee their key messages land. But when it comes to mobile, marketers have to be even more economical. That’s because...

  • Only the first 30 characters of subject lines appear on iPhone's email app.

But even within such restraints, marketers still have to get creative.

  • According to, emails with a subject line emoji have 56% higher open rates.

Complicating matters even further is the minefield of words that kill an email recipient’s vibe.

  • Backlinko also says including “free”, “help”, “percent off”, and “reminder” in subject lines is off-putting and likely to sap open rates.

Key takeaway

All of these variables suggest that no one size fits all email recipients. To best action these insights, you should start your own campaigns, bearing in mind tips and things to avoid. Then dig into your own data and see which cocktail of ingredients works best for your customers.

Open and click-through rates

Open and click-through rates (CTR) are a big deal. Basically, that’s because they show you the fruits of your labour. And according to the Content Marketing Institute, they’re becoming increasingly important to marketers.

  • 35% of business professionals check email on mobile.

This allows you to include banners in every employee email signature to drive traffic to relevant content, offers, events & more. And outgoing emails quickly add up in big corporates....
