How to Use Question Based Emails to Boost Engagement and Segment Your Klaviyo List

Use question based emails to engage customers and collect data for smarter segmentation.

Question-Based Emails – Simple, Strategic, Effective


Question based emails are a quiet advantage in email marketing.

They draw engagement through simplicity—one question, one action—and in doing so, they build cleaner, more informed customer segments.

What do we mean by a “question based email” exactly?

Instead of sending surveys or forms, you ask a single, focused question inside an email. The sole purpose of that message is to prompt one clear action—either a direct reply from the customer or a simple click that applies a tag to their profile.

Because there’s no friction, no extra pages, and no cognitive overload, response rates tend to be higher and more intentional. Each interaction captures a meaningful signal about what the subscriber wants, needs, or cares about right now.

Over time, these small signals compound. As you gather more insights from your list, you’re able to segment more intelligently and shape communication that feels timely, personal, and genuinely relevant—without ever asking for more than a moment of attention.

Why These Emails Actually Work

The psychology is straightforward. People act when the effort is small and the benefit is clear.

A one-click choice or a short reply feels effortless compared to filling out a form.

That difference in friction is what makes question based emails effective. 

They create a natural interaction in the same environment your customer already trusts—their inbox.

These emails work for all kinds of insights: product preferences, satisfaction feedback, or early signals of buying intent. 

Each response adds depth to your understanding of the customer.

Two Formats That Perform Well

Format #1: Button-Based Question Emails

Button-based emails use clickable responses to update customer profiles automatically.

For example, a clothing brand might ask:

“Which color do you wear most often?”

The buttons could be Black, White, Blue, and Red.

Behind each button is a custom Klaviyo link that assigns a tag to the subscriber, using this coding as the URL:

{% update_property_link ‘PROFILE_PROPERTY’ ‘Profile Property Value’ ‘REDIRECT LINK’ %}

Profile property = This would be the category we want to update on the individual profile of the subscriber, in this case it’s “FavoriteColor”

Profile property value = This is the tag that will be applied to the profile when the user clicks a button. So “FavoriteColor” = Blue

Redirect link = This is the redirect link we’re sending people to (all buttons need a redirect link in order to work), so pick a link on your website that is most relevant to the button. E.g. for a “favorite flavor” themed email, you’d add a link that redirects to the webpage with that flavor.

This is then the finished result:

{% update_property_link ‘FavoriteColor’ ‘Blue’ ‘https://yourwebsite.com/blue-collection’ %}

When a subscriber clicks the “Blue” button, Klaviyo records “FavoriteColor = Blue” on their profile. That single action turns into usable data you can segment with later.

Format #2: Plain Text Question Emails

Plain text versions rely on replies rather than clicks.

They often come from the founder and sound like a real conversation.

Example:

Hey {{ first_name }}!

[FOUNDER NAME] here, I’m the co-founder at [COMPANY NAME]

Today I wanted to ask you a question.

Because I noticed it’s been a LONG time since your last order from us.

So I was wondering… did you like it?

Was there anything we could do to make it better for you? 

Maybe a new flavor or ingredient you want us to try…

I’d love to get your feedback, so if there’s anything we can do to improve I’m all ears!

[FOUNDER NAME]
Founder, [COMPANY NAME]
COMPANY LINK

These messages are direct and disarming. They often bring honest answers that surveys miss. Even a few replies can reveal what people actually think about your product or service.

Setting Up The Custom Property in Klaviyo - For Button Question Based Emails

To keep data structured, create a custom profile property before sending your first question email.

  1. Open any subscriber profile in Klaviyo (preferably your own, or a colleague).
  2. Click Add Custom Profile Property.
  3. Name it clearly (e.g., FavouriteColour) – be aware this is case sensitive.
  4. Add the possible values you plan to use—Blue, Red, Green, etc, you will need to update the same property each time, so start with Blue, then change to Red, then Green.
  5. Create segments for each value so you can view them populate as people click, using the below criteria:
    Properties About Someone:
    FavouriteColour = Red


Repeat for all colours. 

Using the Data

When clicks begin to build segments, you can use them in campaigns such as:

  • Personalized product features – “Our best pieces in your favorite color.”
  • Targeted launches – “New arrivals in blue just dropped.”
  • Tailored recommendations – “Since you liked mint, you might like this flavor too.”

     

The data turns mass emails into one-to-one experiences. Relevance leads to stronger engagement, and engagement compounds into revenue over time.

Make Sure You Follow These Rules

Small details have a big impact:

  • Keep one clear question per email.
  • Limit options to three or four.
  • Test every link and tag before sending.
  • Follow up with campaigns that use the data.

These practices keep your system clean and your segmentation consistent.

A Simple Example

Imagine a chocolate brand sends an email asking:

“Which flavor do you prefer?”

The buttons say: Dark, Milk, Caramel, Hazelnut.

Subscribers click their choice. Klaviyo records it.

When a new dark chocolate launches, the brand sends a campaign only to those tagged Dark Chocolate lovers “because you told us you like it”.

That one adjustment often leads to higher engagement and stronger conversions. It’s the same system—just refined.
