What should go in a subject line?
When it comes to subject lines, being concise is key. They’re the preview to what’s in the body — a.k.a. what prompts the recipient to either click on the email, save it for later, or, worst case, delete without opening. Getting your recipient to open your email, especially with genuine interest, is the hardest part, which is why an effective subject line is so crucial.
In an email to Refinery29, Aye Moah, co-founder and Chief of Product of Boomerang for Gmail, said: “The subject line should succinctly portray the purpose of the email, but also have a slight touch of personalization. If you’re writing to someone about a specific job opening, a project or article they worked on, or work that their company has done, note that briefly in the subject. We recommend a format of [topic], [request/question], and [deadline, if any].”
Moah also stresses the importance of sending error-free subject lines. The most frequent faux pas: starting a subject sentence with a lowercase letter. According to this Boomerang study, subject lines of three to four words receive the highest volume of responses.
