Study: Keep Subject Lines At 6 To 10 Words Or Try A Song Lyric To Lift Email Open Rates

Retention Science logo Feb 2014After analyzing more than 260 million emails across 540 retail email marketing campaigns, marketing analytics firm Retention Science found email subject lines kept at six to ten words resulted in a 21 percent open rate.

According to the study findings, while six to ten word subject lines delivered the highest open rate, email subject lines with five or fewer words generated a 16 percent open rate.

Retention Science claimed 52 percent of the emails the company evaluated had subject lines with eleven to fifteen words, dropping open rates to 14 percent.

While some studies have reported email marketing mobile open rates as high as 65 percent, Retention Science said 35 percent of the emails in its study were opened on a mobile device, reinforcing the importance of keeping subject lines short:

Given that most smartphones only display five or six words of a subject line, being brief and concise is even more critical in the mobile marketing world.

To help increase open rates, Retention Science recommends using a person’s name in the subject line, or a movie title or song lyric.

The study discovered email subject lines personalized with a recipient’s first name lifted open rates by 2.6 percent.

Retention Science noted the emerging trend of using movie titles and song lyrics in subject lines has also helped email marketers increase open rates.

“Movie and music references can be targeted to certain customer segments or encapsulate a promotional theme, making them a creative way to hyper-target and capture attention,” says Retention Science CEO Jerry Jao.

Citing a separate study, the analytics firm revealed subject lines with movie titles and song lyrics had a 26 percent open rate, compared to emails with “more traditional subject lines” that resulted in a 16 percent open rate.

How to Get SMS Alerts for Gmail via Twitter

How do you get SMS notifications on your mobile phone for important emails in your Gmail? Google doesn’t support text notifications for their email service but Twitter does. If we can figure out a way to connect our Twitter and Gmail accounts, the Gmail notifications can arrive as text on our mobile via Twitter. Let me explain:Twitter allows you to follow any @user via a simple SMS. They provide short codes for all countries (see list) and if you text FOLLOW to this shortcode following by the  username, any tweets from that user will arrive in your phone as text notifications. For instance, if you are in the US, you can tweet FOLLOW labnol to 40404 to get my tweets as text messages. Similarly, users in India can text FOLLOW labnol to 9248948837 to get the tweets via SMS.The short code service of Twitter can act as a Gmail SMS notifier. You create a new Twitter account, set the privacy to private and this account will send a tweet when you get a new email in Gmail. Follow this account …

Majestic, the link intelligence database that many SEOs have come to use on a daily basis, has dropped the “SEO” from it’s brand and from its domain name, to become Since most people won’t have used Google’s site migration tool before, here’s what it looks like once you press the “go” button:

Fortunately, elsewhere in GWT its clear the omission is on Google’s side, not a typo from the SEO. It is most likely that the migration tool was developed before the need for Google to have separate verification codes for http and https versions of the site.
