What Is A Reminder Email?

A reminder email is exactly what it sounds like – an email sent to remind someone to take a specific action.

For example, if someone leaves items in their online shopping cart but doesn’t complete the purchase, you can send them a reminder email encouraging them to come back and checkout. Or if a customer signed up for a free trial but hasn’t become a paying member yet, you can use a reminder email to prompt them to subscribe.

Reminders can also go out for upcoming appointments, webinar registrations, account renewals, events, and more.

The goal is to jog the receiver’s memory to complete a pending task or take advantage of an offer before it expires.

Impact of a Good Subject Line in Reminder Emails

The key element that determines whether a reminder email gets attention or not is the subject line. With inboxes flooded every day, a vague or boring subject will lead to the email being ignored or trashed.

However, catchy and personalized subject lines can significantly improve your reminder email open rates.

Some specific benefits of good subject lines for reminder emails include:

  • Grabs the reader’s attention right away amidst an inbox crammed with emails
  • Clearly conveys in a few words what action the email is reminding them to take
  • Triggers the memory of the reader so they recognize what the email refers to
  • Gets more open, increasing the chance they’ll complete the intended action after reading

In short, carefully crafted subject lines help your reminder emails cut through the noise, reconnect with recipients and ultimately drive more conversions by getting people to take pending or desired actions.

Best Practices In Crafting Reminder Email Subject Lines

Here are some best practices to ensure your reminder email subject lines are engaging and prompt the desired action:

  1. Be Clear and Direct: Your subject line should leave no room for guesswork. It needs to be straightforward, telling the receivers exactly what the email is about. Whether it’s a payment reminder or a nudge to complete a purchase, clarity is key. This approach respects your time and attention, making it more likely that you’ll engage with the email.
  2. Create a Sense of Urgency: Without sounding alarmist, your subject line should convey a sense of timeliness. Phrases like “Last Chance” or “Don’t Miss Out” can be effective. This tactic taps into a natural desire to not miss out on something important or beneficial, encouraging you to open the email and take action.
  3. Personalize When Possible: If you can personalize the subject line, do it. Including your name or a specific reference to an action you took (like adding items to a cart) makes the email feel more relevant to you. Personalization can transform a generic reminder into a message that feels tailor-made for you.
  4. Keep It Short and Sweet: With the majority of emails being opened on mobile devices, it’s crucial to keep subject lines concise. Aim for a length that’s easily readable on a small screen, ensuring that the key message isn’t cut off. A shorter, punchier subject line is often more impactful.
  5. Balance Urgency with Politeness: While it’s important to convey urgency, it’s equally important to maintain a polite and respectful tone. Your subject line should nudge, not push. Phrases that are too aggressive can be off-putting, while a courteous tone is more likely to be well-received.
