Marketers have been using email to conduct customer surveys for years. Despite emerging marketing trends like social media and live chat, it remains the most effective channel to reach customers.

Crafting compelling survey email subject lines is the first step to getting valuable feedback via email. According to Invesp, 69% of email recipients mark emails as spam based on subject lines alone. So, a well-formulated subject line is crucial to getting your emails noticed and opened. Once opened, chances increase that you’ll actually get this valuable feedback you are after.

Let’s have a look at 3 fundamental guidelines for correctly selecting effective survey email subject lines that can boost the open rates. Afterward, we will explore several practical writing tactics that will make your subject lines stand out from the rest, including some examples.

3 Guidelines for Effective Survey Email Subject Lines

1. Set Clear Expectations Based on Actual Survey Design

Before you start writing your subject lines, you need to develop a survey design, ensuring the survey flow and structure are on point. Survey design is the process of creating surveys that provide maximum insight. In other words, it’s about asking the right questions to the right people at the right time.

Developing the right survey design ensures the answers to your questions are relevant and accurate. Your subject lines can help or hinder the feedback collection. Understanding your survey design will help you create subject lines that set clear expectations and don’t mislead customers.

For example, when you know how long the survey takes, you can honestly put ‘A minute (or however long) of your time?’ in the subject line.

2. Choose the Right Keywords and Tone of Voice

Knowing your audience helps you create subject lines they are likely to respond to. For instance, millennials use visuals like GIFs and emojis to communicate, so incorporating emojis in subject lines could be an advantage for that demographic.

The timing is another factor of survey design you can use to write subject lines. Let’s say data security is a trending topic in your industry. Including data privacy keywords is a timely and great way to get people to click on your email surveys.

3. Be Precise About Your Survey’s Purpose

Successful surveys are clear about what they’re asking customers. To use emails effectively for feedback collection, you need to define your survey’s goals, which will inform the wording of your subject lines.

Are you collecting feedback about an event or purchase? Are you measuring customer experience or customer loyalty? Are you looking for innovative ways to stay competitive? Your customers should be able to know what the survey is about from the subject line.

Clarity on survey objectives makes it easier to construct relevant email subject lines.

The subject line ‘‘So… how about our new live chat feature?’ specifies that the survey is about a particular product feature.

From the subject line in the image above - “How did we do?”, the email recipient immediately knows that the email is asking for feedback on a recent experience.

How to Create Catchy Subject Bylines

Writing great survey email subject lines can be tricky, even for the creatives among us. Fortunately, the best practices used in other email marketing communication apply to survey emails.

Here are a few tactics to make your email survey subject lines stand out.

1. Personalization

Out of all the emails customers get, the ones most likely to grab their attention have an element of personalization in the subject line. But email personalization isn’t just inserting subscribers’ names in subject lines.

Tap into your customers’ history to create relevant subject lines and refer to their last purchase or browsing session. Subject lines about products or services customers haven’t bought or used are a marketing red flag. It shows you don’t know or care about your customers.

You can also include locations. For example, the subject line ‘Dallas votes Tikki Pies Best in Town. Agree?’ is sure to attract customers from that city. Be sure to customize for other regions.

2. Ask a Question

Asking questions is a great way to grab subscribers’ attention. Something like ‘Got a minute?’ can be more engaging than merely referencing their website activity.

To improve your open rates, ask questions about their pain points. For example, ‘Are you handling employee retention correctly?’ is sure to pique interest. If they weren’t wondering before, they are now.

3. Use Incentives

Offering incentives is an effective way for your marketing team to get customers to complete in-person and online surveys. Incentives boost survey response rates and let participants know you value their time.

For example, you may mention in the subject line that participants will receive a particular reward upon completing the survey.

While rewards are likely to increase long survey completion rates, you must be strategic with the wording of your subject lines. There are words you should never use if you want to avoid spam filters. These include ‘money back,’ ‘cash’’, ‘gift included,’ ‘limited time,’ dollar signs, and all caps. The list goes on.

4. Use Emojis

You may be concerned with how emojis align with your brand message, but according to a study by Return Path, brands that used emojis in the subject lines enjoy higher read rates than ones using text only.

For example, using the bunny emoji for Easter promotions yielded a 24% read rate compared to a 19% read rate for regular Easter promotion emails. Emojis help your email surveys stand out in crowded inboxes and fit mobile phone formats.

5. Keep It Short

How short should your survey email subject lines be? The screen orientation of mobile phones is vertical compared to the horizontal layout of desktops. That leaves limited character space in the subject line box.

Consider that the preferred business communication channel for 46% of smartphone users is email. If you want mobile users to open your survey emails, your subject lines should be able to fit mobile device formats correctly. Aim for a limit of 50 characters.

When it comes to email survey subject lines, short and personalized is the best way to go. As with other email campaigns, analyze subject lines to see what works for your customers. If you can track the engagement rate of a digital business card, you can track subject line performance.
