You want to improve your business strategy and you are full of energy to make it better. To know which way to go you start sending out survey emails to your clients, but hardly ever receive any response? No wonder because the average survey response rate is about 10%, and only for big world-famous companies this number may reach the 25% point.

In this post, we’ll show proven ways to increase the conversion rate of online survey email invitations and share the best, in our opinion, examples.

And will provide you with some ready-to-use templates.

10 best practices to send better survey invitation emails and increase your survey response rate

A survey email is a questionnaire sent to existing customers. How many questions should they consist of? Depends on you. 

Fortunately, all survey messages have similar features, and similar purposes — to check out customer’s satisfaction, and they all are quite alike. 

1. Offer discounts and coupons

People normally are not really interested in filling surveys out. But you can persuade them to do it by offering a discount. Let it be 15% OFF for the next purchase, or anything like that. Or you can also offer them a coupon.

2. Keep the survey short

Why short? The shorter the questionnaire is, the more chances your clients will respond to it. A good way to keep the survey short is bringing no more than 4 questions. People will love it if you appreciate their time.

If the invitee has recently experienced your products or service, the preferable form here will consist of just one question: Did you enjoy the visit? Or how likely are you to recommend us to your friend?

If the answer is positive, then do not reply to this message. But if the answer is negative, it would be reasonable to send a longer survey with 4-9 questions.

The way it’s done:

• you just insert 10 images with numbers and add respective links to each image;

• users will click the image that corresponds to their opinion;

• your ESP will provide you with a detailed report;

• be sure to send a follow-up email to those who took your survey.

Sometimes you need to create a longer questionnaire with more than 20 questions. When long surveys are a must? For educational programs, like online course platforms, for those who host webinars and conferences, and for those who conduct investigations, like Litmus. In this case…

3. Mention how long the survey might take your customers

If you want people to answer your questions, you need to tell how long it will take them to do so. If the survey is long and may take 20 minutes, be honest. Say it!

Speaking of time, be sure to mention the expiry date. In rare cases, some people postpone filling out the forms and want to do it in the evening or at the weekend when they have some spare time. Consequently, it will be really nice of you to make a note on how long the survey is available.

Especially, if this is a long one.

Please be advised: After the expiration date, the survey link/website page should inform your clients that the survey is over.

4. Be sure to share the results

When people spend their time doing something, or when they vote for some changes, they naturally want to hear the results. Promise them at the beginning of your survey invitation email that you will share the results.

Be sure to share the results once you have promised. Add some testimonials if you like.

5. Add photos of the products you are asking recipients to review

For sure, you are not the only online store people shop with.

By adding photos of recently purchased products, you will remind recipients of what exactly you are talking about.

6. Send a survey invitation reminder

I normally open a survey with the intention to complete it. But quite often I get interrupted and do not complete the survey, and of course, by the end of the day, I forgot I wanted to do it.

(Source: Newsletter email from Growth Marketing)

Always send a reminder if you want to collect as many responses as possible.

7. Show your gratitude

Always thank customers for what they do. First of all, in order to be polite. Second of all, people need to feel appreciated. Because in fact, by completing the survey they did us a favor. Third of all, this way we let them know their vote has been accepted.

8. Embed surveys when that’s possible

In some blog posts of ours, we already shared the results of our test:

AMP forms, embedded in survey invitation emails, worked 5.1 times better than those emails with a link to Google Form.

Try Stripo out

Please refer to our respective blog post where we show how to embed AMP forms.

Important:

In the short run, we will release our new AMP-form block. It will allow you to build forms, use them in survey emails and see users’ responses right away.

9. Explain the purpose of the survey

Let subscribers know you run this survey for them. Of course, it will work only if you really share useful information with your readers.

(Source: Newsletter Email from Neil Patel)

And intros like, “I would like to know” will not do.

10. Work on a survey invitation email subject line

Now that you know for sure what ingredients you added in your emails, you may thoroughly think about the subject line.

It’s a commonly known fact that an email subject line is one of three key factors that determine whether subscribers will open your emails.

Subject lines are to be:

• highly informative — the reason why you are reaching out to customers;

• descriptive — what particular question are you interested in and how long it will last;

• personalized — it is optional.

Examples of survey invitation email subject lines 

1. Maybelline — We want to hear from you!

2. GetResponse — We’d love your help! Fill out the quick survey and help us make GR better.

3. Adweek — [SURVEY] B2B Data-Driven Marketing.

4. ReallyGoodEmails — Survey says… 

5. Hubspot — Take Our Survey on Customer Support and Service Salaries.

6. Slack — Help us improve Slack by taking this survey.

7. Insurify — Thank you + Quick question.

9. Netflix — Netflix values your opinion.

10. The Frye Company — $50 for your thoughts.

11. Thumbtack — Tell us what you think about Thumbtack in 30 seconds.

12. Pinterest — Hanna, got a sec? Give us feedback on…

13. Neil Patel — I need your help.

18.  Mailgun — Questions about Mailgun - can you help?

19. Email on Acid — We need a little help with our New Year’s resolution… 

Important:

Please be advised that you can set subject lines and preheader in Stripo.

How to make a survey invitation email

There are three types of surveys in emails:

1. embedded forms;

2. links to questionnaires;

3. images/icons with links to them.

1. Embedded forms

Benefits of embedded forms:

1. they noticeably increase response rate;

2. you can see the answers right away;

3. AMP form shows who exactly responded to your email and what the rate was.

Stripo allows you to embed Google forms and innovative AMP forms.

AMP forms

AMP forms allow recipients to rate you — your service, your products, etc. — and leave a comment directly in email.

Like we said above, our tests showed that the ability to fill out the form in emails with no extra moves increased our response rate by 5.1 times compared to links to external forms.

How to use an AMP form in emails

Very soon, we will release an AMP form drag-n-drop block. You will just need to pull it into your email and enter your questions — that’s it.

But today, in order to build this form, you may just use our survey email invitation template — it already contains the AMP form.

Use this template

But then you will have to insert an end-point to your server, where all answers and other data will be collected.

With our Mock server, you can create a mock end-point to check if your questionnaire really works.

Then your developers will build a similar but real one for you on your servers — it will take them just a few hours. 

Please, refer to this blog post to find a full guide on how to work with our Mock server.

Important:

AMP forms work in Gmail on desktop and Android — iOS to support it soon, — and in Mail.ru both mobile and desktop devices.

Outlook.com, AOL.com, Yahoo to support these forms soon too.

All users who do not see the AMP form, will see the fallback — the template we previously shared with you already contains the AMP form and a fallback survey invitation button (you will only need to insert a link to your website feedback page, or a Google form).

Get started

Google forms

Google forms are easy to work with. Google already has free templates that you can customize and use. Apply your fonts, add images to the questions, or change the header background. Google even allows inserting videos into the survey. You can add as many questions as you want. Once you have created the survey form, export the email to your ESP. Google forms are free of charge.

How to embed a Google form in emails

• create Google form;

• prior to sending the form to your Inbox, make sure to tick the “include in email” checkbox;

• open the email and with the right-click select “inspect”;

• search for the table align=”center” line, copy it;

• in Stripo, pull the basic HTML block directly in your survey invitation email sample;

• replace the “insert HTML code” with your embed code.

Done!

Get started

Important:

This email survey works well in Gmail, AOL, Yahoo! Mail, and Rambler.ru in Google Chrome, Mozilla Firefox, Safari, Opera. It works on desktops only.

Mobile users and those recipients who use other email clients will see the link to the survey. They might also be directed to the Google Form once they fill out the form and click the "Submit" button (in Mail.ru, Apple Mail).

2. Links to questionnaires

Benefits of these questionnaires:

They are totally web-safe since they are represented as URLs wrapped in CTA buttons.

You may build a questionnaire either with Google form, or SurveyMonkey, or build one on your website, or even your ESP might build one for you and provide you with a link.

How to add these questionnaires in your emails

Just as a regular link you use in buttons.

Make sure the CTA button is noticeable and its CTA copy is clear and convincing enough.

3. Images/icons with links to them

Use icons or images when asking users to rate your services.

Benefits of images/icons with links:

• works in all popular devices and email clients;

• easy to collect data and analyze responses.

This survey request email sample shows how imagery can be used for surveys.

(Source: Newsletter email from HubSpot)

How to add this imagery in your emails

• drag a structure with a necessary number of columns. Please be advised you can add up to 8 of them with Stripo;

• pull the Image block into each column;

• upload images/icons;

• add proper links to each icon;

• be sure to enter Alt texts to all images — if images are blocked in an email client, users will know what specific icon they are clicking on.

Get started

Best time for survey invitation emails

Long questionnaires on products, public events, etc. should be sent in the evening when people are home, relaxing.

If the questionnaire is pretty short and consists of only 2-3 questions, you may send it anytime during the day.

But if your survey is meant to gather info regarding some office programs, please send them during the working hours when people are at work and are ready to answer all your questions to help you improve your apps.

But still, you/your ESP have already analyzed the best time for your newsletters. You may use this time for the survey invitation emails.

5 survey email invitation examples

I find the examples below interesting enough.

Hope you also will find them inspiring and useful.

1. Annual report — Stripo

This email contained an embedded AMP form. Our recipients could share their opinion about us directly in this email.

We ran an A/B testing. And, as we said above, AMP form brought us 5.1 times more responses than the traditional link to Google form.

Get started

2. Take our 2020 Product Management Survey — ProductPlan

This email is simple, the company in its subject line let me know the goal of the survey. And they warned me how long it was going to take me to complete the survey.

3. Take the 2019 State of Email survey — Litmus

I loved the intro — Litmus reminded its audience that we all use their statistics. Pretty convincing reason to take the survey, isn’t it?

4. Survey says... — Really Good Emails

Really Good Emails shared the results of the survey. Loved it because only some companies actually do that.

5. Gift card for your thoughts on Campaign Precheck? — Email on Acid

In fact, when a company improves its service, it does a favor for its users. Nevertheless, it won’t hurt if they offer a coupon or a gift card for a review.

Email on Acid was the first tool to check emails for accessibility. This feature made them extremely useful for all email marketers. However, Email on Acid ran a survey where asked users for their opinion on what they should improve in their testing tool.

Final thoughts

We have analyzed best practices to improve the survey invitation emails and provided the best email survey invitation examples. We are sure that sticking to these rules will help you reach the goal — increase the survey invitation responses.
