30 Best Subject Lines for Your Next Survey Email

If you’re an ecommerce store and want to build trust with your customers, there are many things to consider. In this article, we’ll discuss everything about email subject lines. 

The subject line is one of the crucial elements that impact the success of your email campaigns. In fact, 47% of recipients decide whether to open an email solely based on the subject line. 

This stat alone shows why you should craft the best email subject line for your survey emails.

With that in mind, we’ll show you how to create survey email subject lines that cut through the noise, captivate your target audience, and boost your marketing campaigns’ success.

How to craft engaging survey subject lines

Let’s look at some proven tips to create subject lines for survey emails that engage your audience and drive meaningful interactions through your email campaigns. 

1. Personalize your survey subject lines

Some ways you can personalize your survey email subject lines include: 

• Using the subscriber’s first name — “[first name], do you like our products so far?”
• Addressing the customer directly — “A quick favor?”
• Referencing a product the user bought from you recently — “You bought [product name] from us. How have you found it so far?”

Here’s a brilliant example from Withings:

Survey subject line: Help us help you, Smiles Davis

Withings has personalized its survey email subject line with the recipient’s name, making the subscriber feel singled out (in a good way). 

The company makes it clear it wants the recipient’s opinion so it can develop better products for them. As a result, the chances of the customer responding to the email are much higher. 

2. Ask questions

Another good approach is to ask recipients a question that initiates a conversation with them. 

Here’s an excellent example from J.Crew:

Survey subject line: Thoughts?

This simple email survey subject line makes the message stand out in a crowded inbox. It engages the recipient by making them feel that the company values what they think about its products and that their opinion matters. It also avoids the spammy “take our survey” vibe.

Questions can make perfect survey email subject lines for general surveys about your business and past purchases. You can also schedule automated product survey emails to be sent after customers have had a chance to experience your products.

3. Incentivize your recipients

Incentives can significantly increase survey response rates since they give recipients a compelling reason to participate — the chance to get a discount or win a prize. 

Moreover, it’s pretty hard for someone to ignore a subject line that says they’ll get a free item or a discount.

Here’s an excellent example from Aero: 

Survey subject line: Take our survey to get 10% off your next Aero flight.

The brand incentivizes recipients with a 10% discount on their next flight by simply participating in the survey. As a result, it draws attention and convinces the subscriber to open the email. 

4. A/B test your survey subject lines

A/B testing is sending one variation of an email to a group of your audience and another version to a second subset of the same audience. 

The variation with the most opens, clicks, or conversions will help you understand what your customers want so you can apply those results to future email campaigns.

You can A/B test various elements in your email, including different writing techniques, email design, call-to-action (CTA), and email copy. In this case, you’ll be A/B testing the subject line. 

You can send two different subject line versions with the same email body copy. That way, you can be sure you’re getting results based on the subject lines alone, not other elements in the body copy. 

After running your test, you can determine which subject line performed better and use those results to inform future survey email campaigns.
