In this article, we define what a follow-up email subject line is, explain its importance, share tips on how to write a good one, and provide examples to guide you.

What is a follow-up email subject line?

A follow-up email subject line is the single line of text the recipient sees when they receive an email referring to a pending engagement or transaction. This heading often gives the recipient an idea of what the email contains and the requests that might follow. The follow-up subject line often determines whether the receiver opens the email and continues the engagement or considers it spam. Using appropriate professional language and personalizing your subject line can increase your chances of receiving a response.

An effective follow-up subject line can capture your recipient's attention and increase your chances of receiving a response to your inquiry. It also allows you to interest the recipient to help you build a direct relationship with them. For example, if you own a grocery store, sending a follow-up email that addresses your customers' concerns can add value to their experience throughout the sales journey. An effective follow-up subject line can help prevent your email from landing in the recipient's junk or spam folder.

Tips for writing an effective follow-up email subject line

When writing a follow-up subject line, try to gain the receiver's attention while coming across as easygoing. Here are some tips you can use to write a professional follow-up email subject line:

  • Use a natural and conversational tone. A conversational tone conveys to the reader that you're sincere and easygoing. Writing in this manner may make it easier for the receiver to respond to your email.

  • Make the subject line brief. A short and straightforward subject line can help the reader quickly understand the message. You may use six to 10 words to convey your message.

  • Make the subject line personal. When sending a follow-up email to the recipient, including their name or mentioning a shared experience can help you personalize the message. Doing this may inspire the reader to reply.

  • Optimize the snippet. The snippet is the short amount of text that appears near the subject line. It gives the receiver a preview of your message. To optimize the snippet, include the recipient's name, ask a meaningful question, or recount a shared memory.

  • Build a sense of curiosity. Create follow-up subject lines that don't disclose the full details of your email. A leading subject line can induce curiosity and inspire the recipient to respond.

  • Create subject lines that relate to the body of your email. Match the body of your email to the follow-up subject line. This correlation allows the recipient to respond to the email quickly and efficiently.
