Subject Line Length- An analysis of 9 313 885 emails to discover most effective length

“The Idea Email,” and is made up of one landscaped image, a headline and the 350 words of copy.

With mobile overtaking the desktop for email open rates, I was doing some research this afternoon on the viewable length of subject lines on a mobile device. Subject lines are typically more important than the email content itself when it comes to the behavior of the reader and whether or not they’re going to open the email.

Now that most email is open on a mobile device, the number of characters you have on an iPhone, Android, Windows or Blackberry device is incredibly short… ranging between just 33 and 44 characters. Our subject here… Mobile Email Subject Line Displays comes in at just 34 characters. That’s not a lot of room to raise the curiosity of our reader and get them to open – quite a challenge for email marketers.

Here are some tips from 2015 on how to improve your newsletters:

  1. Write your e-newsletter as an email to a favorite client – don’t add graphics, don’t use headers or footers instead just keep it a simple plain text email.  You’ll be amazed at the response. This keeps it personal and helps you avoid sounding like a salesman.
  2. Add a contest or giveaway – give your customers a reason to open these emails, keep it fun.
  3. Keep it simple, too much information and they will pass it by.
  4. Make sure you have one goal in mind and create a strong call to action for that goal in a color that stands out – to invite the reader to take action.
  5. Test it – send it out, look at it on your mobile device and make sure it looks good on a smart phone.
  6. Pair down the copy – take out all the unnecessary copy, keep it as simple as possible.
  7. Bold important concepts
  8. Use strong sub heads to break out copy.  Think of those sub heads as headlines and take time to make them catch the eye.
  9. Send the Enewsletter from a Human Being – instead of sending it from a company  name use a real person’s name.
  10. Use an outside service:  I’m still amazed to find clients emailing mass emails from their personal accounts.  This is a great way to get your email blacklisted and you won’t have deduping and proper unsubscribes.  So most likely, you are not following the law.

100 Spam Trigger Words & Phrases To Avoid

(Note: I am going to assume you are not using words like sex, Viagra and other spam filter trigger words in an honest e-campaign, so obvious ones like that have been intentionally left out of this list.)
