A three-month analysis of your email campaigns shows that

A three-month analysis of your email campaigns shows that this is a consistent practice in which the theme and average length of headers are very close to the iPhone guidelines. In this clever example, Boursorama Bank, existing customers are encouraged to make recommendations, but email also serves as a measure of value, reminding them that over a 10-year period “some things don’t change” and that they remain the cheapest bank. Subject lines play an important role in attracting attention and convincing recipients that opening email is worthwhile, and shortening the subject line means that there are only limited ways to do it well. Cheetah Digital calculates the average value of an open email at ±0.36€, while Bluecore indicates the opportunity cost of deleting an email at ±16€. This is smart because the iPhone’s native messaging application displays 30 to 40 characters of a subject line and twice as many characters of preview text. Most email marketers continue to focus on subject line optimization: short or long, generic or personalized, more effective keywords, etc. Litmus Research reports that the average reading time of an email is 11 seconds. We have already looked at the UK and Australia when I analysed these email markets in preparation for my Return Path World Tour keynote lectures, and now we are going to look at France. When much of this valuable time is spent identifying the most important content, the effectiveness of email decreases considerably.
