The Rest of the Month

Average Score: Trending Up

May’s average CTR was 23.36%, significantly up from April’s 17.27% (a 35% improvement).

 

Average Length: Trending Down

Characters: 31-40 characters was once again the dominant grouping. Unlike in April [link here], no other bracket came close. The overall average was slightly down on April, at 44.63 characters.

 

Words: No change here, with the vast majority of subject lines falling in the 1-10 words grouping. The degree of dominance grew slightly with 87.74% of subject lines (up from 86%).

 

Word Length: Consistency once again; 6-10 letter words made up 94% of the content this month.

 

Personalisation: Trending Down, Performing Well

“#First_Name#? #First_Name#? #First_Name#?”

Fewer than 10% of May’s subject lines contained any personalisation.

Those that did still outperform those that didn’t, although the performance gap was narrower this month than in April.

 

Emojis: Trending Up (Just), Performing Quite Well

A slight improvement in fortunes for the emoji this month, appearing in 5.16% of subject lines (up from 3.33% in April).

This was accompanied by a reversal in performance, as subject lines with emojis slightly outperformed those without (16.67% CTR vs. 16.05%). A blip or a new lease of life? Watch this space to find out!

 

Sender Name: Trending Up,  Performing Badly

The number of subject lines containing a Sender Name shifted up by 4 from April to May (14.67% to 16.67%).

However, there was also a 4-point drop in CTR for this group, taking their overall performance below that of their non-Sender Name rivals (14.96% average CTR vs. 16.31%).

 

Type

Sales/Marketing subject lines still dominate, edging closer to 50% of the data in May. Newsletters and Functional sends dropped slightly, with Events taking up the slack.

 

Sending Day

After a murky picture in April, with all the days clumped together, we saw a significant difference in May. Monday was the most effective day overall, the first time in a while that a weekend day lost this title.

However, overall the weekend still outperformed the working week, with an average CTR of 15.78%, compared to 14.82% for Monday to Friday.
