1. Emotions are important

Looking back at the emails that you receive, think about the emotions that they awake in you. If you’re having trouble figuring out what emotions they bring, it’s because not many businesses understand the art of psychology in emails.

It’s obvious why subject lines such as “let us know what you think” do not gather the attention of the subscriber. The reason for this is because some of your customers are impulsive buyers. Hence, they’ve purchased based on the emotion they have felt right in that moment rather than logic.

Furthermore, it’s crucial to create a sense of urgency as it will encourage the recipient to take immediate action. You should use the following examples:

• “Urgent: Has your problem been solved?”

• “Few hours remaining to inspire us?”

• “Are we up to your standards?”

This will not only encourage the subscriber to open the email but to also respond to the survey.

2. Incentives always help

You can reference the incentive in the survey email subject lines. This will not only bring attention to your email, but it will also encourage the recipient to open it. Nonetheless, you have to remember that it will also bring unwanted attention to it. For example, some will answer just for the incentive.

• “Share your thoughts and get purchase credits.”

• “We get the feedback; you get the discount code. Deal?”

•  “We want to hear your thoughts.”

4. Humor helps

It’s not every day that you see humor being used in subject lines. Therefore, if you want to stay ahead of your competitors, you should use it. Of course, this is another risky decision to make as too much can do more damage than good. In addition to this, you also have to be careful about not offending any subscribers.

The beauty of humor is that you can be creative with it. Here are some excellent tips:

• “Our heads hurt and we still can’t figure it out. Help us?”

• “It’s obvious, but we still can’t find it. Help!”

• Use emojis

When it comes to emojis, you have to remember that not all of your subscribers will own the same mobile device. Therefore, you should use them with caution.

5. Make it clear

If you don’t want to go over the top, you should tell the subscriber the purpose of the email in the subject line. On the other hand, making it clear, goes beyond than just the message of the campaign.

A classic mistake that numerous businesses make is to influence the respond of the recipient. Even though you should indeed encourage them to respond, you should encourage them on how to reply. Thus, you should stay away from phrases such as:

• “Tell us what’s awesome with us.”

• “We need feedback.”

• “Aren’t we great?”

In doing so, you risk getting reported and sent to the spam folder. A good example of word choice would be “Share your experience.” This gives out a clear message, and it’s short and straightforward.


By nature, surveys aren’t a thing that will make the subscribers jump out of their seats. It’s not exciting, but you can make it engaging. When it comes to survey email subject lines, you should use creativity to get you beyond the hurdle. Also, every audience is different, so it will take trial and error to find the best formula for your business.
