A subject line is more than just a catchy opening…

A subject line is more than just a catchy opening to an email. It often has a specific purpose and differentiates your email from the competition. Whether promoting a product or offering a deal, crafting a subject line that appeals to your audience is essential. A referral email subject line is an important determinant of the number of responses your email elicits.

In this guide, you’ll learn the secrets to crafting a powerful subject line for your referral email.

Why the Subject Line Is Important

The subject line is the first impression your email makes on your contact. It is an opportunity to make your email stand out from the sea of others in the recipient’s inbox.

The subject line influences the recipient’s decision-making process of clicking to see more. It is also a great indicator of whether they’ll take action or ignore it.

Your email subject line should capture attention up-front. It should let the reader know what the email is about and give them a reason to open it. The most effective subject lines have a direct call to action prompting the reader to take necessary steps.

What Is a Referral Email?

Referral emails are used by businesses to find prospective clients through their existing customers. They leverage the current customer’s network to find qualified leads who may have similar pain points or needs. Such emails are sent to the business’ customers with information about its referral programs.

A referral email is a marketing tool that encourages current customers to share a brand with friends, family, or connections. This type of email usually includes incentives or rewards for the recipients. Referral emails are a powerful way to push your influence and attain benefits such as higher ROI and employee referral bonuses.

The best referral emails use clear subject lines. Crafting your subject line will depend on factors like:

  • The goal you want to achieve with the email,
  • The value you’re offering the recipient, and
  • How to make the subject line stand out from other emails.

Features of a Good Referral Email Subject Line

The email subject line can make the difference between landing a new client and losing a dissatisfied one. The most successful referral email subject lines are:

1. Precise and to-the-Point

Your referral email subject line should be enticing enough for recipients to open the email. Clear subject lines will attract more opens and click-throughs than vague ones. People usually want to know why they should open your email – go straight to the point! Your subject line must tell the reader precisely what your email is about and how it will benefit them.

2. Short

Most often, a concise subject line works best. There’s a limit of 60 characters for the subject line on mobile devices before it gets cut off. Keep your subject line between 40-50 characters at best. This way, your subject line will be fully displayed on all devices.

3. Spark Interest

Your email subject line aims to grab the reader’s attention and entice them to open the email. Use emotional-trigger words that pique the recipient’s Interest. Provide them with an offer they cannot resist. Do not make false promises – stick to only real incentives.

4. Personalized

Your email subject line should speak to the recipient directly. This way, they’ll know they’re not receiving a bulk campaign email. Personalizing the subject line will increase the chances of getting the email opened. You can include the client’s name or use pronouns like “You/Your” in the subject line.
