Create better emails with instant text quality scoring

Subject length

Keep subject lines short and personal. More often, emails are opened on mobile devices where long subject lines can get cut off. Overall, subject lines with 3-7 words show better results than longer ones.

Word count

Make sure your email body is up to 125 words – these are +20% more likely to be replied to compared with longer ones of 150+ words. Long advertising or sales copies rarely get read and are usually ignored.

Question count

Make your email actionable. Ask a recipient a question to answer; two questions in the email tend to provide +20% RR (reply rate) compared with emails that don’t have questions at all.

Reading level

Always check if your text is easy to read. Surprisingly, emails written at a third grade reading level are most likely to get a response.


Positivity defines how positive, neutral, or negative the context of your email is. The highest response rate(s) come from emails that are positive in tone.
