Subject line stats that matter

Email inboxes in the modern day are nothing short of a digital cacophony of noise. Left alone, your unread emails will stack up very quickly, with emails coming from a whole host of sources talking about a range of different topics. Relating to my own role, I’ve now accrued a mighty list of PPC and Digital Marketing newsletters that populate my inbox, with the subject line often being the only distinguishing factor in my decision to open or skip past an email.

For the email marketer, this makes grabbing the attention of your audience more difficult, but when done right, it can totally transform your results and open rates. As your subject line is the first point of contact with your intended audience, mastering the subject line is the difference between an opened email and just another unread email bound to the annals of history.

In this blog, we intend to explore the world of statistics to gain a deeper understanding of the science behind subject lines and discover the secrets that make users stop scrolling and engage with your content.

Bolster Your Marketing Efforts With Embryo

Crafting an enticing email subject line is key to your email open rate success. Data suggests that a more personalised approach leads to a more engaged audience, while FOMO and curiosity are also big “hooks” that can help capture your audience’s attention.

Subject to endless emails on a neverending basis, mastering the art of the subject line is the clear-cut way to separate yourself from the crowd.

In short, writing an email with a generic subject line is the quickest way to waste a marketing effort. Take the time to know your audience and tailor your email subject line to the person who’s receiving it. Only then will you sow the seeds of success.
