What to build
Now let's walk through how to use Kinetic at every stage of your customer's journey.
WELCOME
Match customers to their stack before the first bottle ships.
Most supplement brands send a welcome email with a discount code and a "shop all" link. That tells you nothing about the customer. They could care about sleep, energy, immunity, or weight loss — you have no idea. So every email after that is a guess.
Four questions fix that:
What are your top wellness goals? (Multi-select, max 3: Energy / Sleep / Immunity / Stress relief / Fitness / Beauty & skin / Weight management / Digestion)
Any dietary restrictions? (Multi-select: Vegan / Gluten-free / Dairy-free / Nut allergy / None)
What format do you prefer? (Single select: Capsules / Gummies / Powder / Liquid / No preference)
How experienced are you with supplements? (Single select: New to supplements / I take a few / I have a full daily routine)
Here's where the real value starts.
The quiz gives you a customer profile. What matters is what you do with it.
Email 2 (day 2): "Your personalized stack is ready."
3-4 supplements matched to their goals, in their preferred format, filtered for their dietary restrictions. Not "top sellers" — their specific recommendations.
Email 3 (day 4): "Why we recommended [product] for [their #1 goal]."
A "sleep" customer gets education about magnesium and L-theanine. An "immunity" customer gets a breakdown of zinc, vitamin C, and elderberry. Same template, completely different content.
Email 4 (day 7): "How to take your supplements for the best results."
Timing and dosage guide personalized to their stack. Morning vs. evening. With food vs. empty stomach. Specific to what they were recommended.
The lighter version: Gate your welcome discount.
A full quiz isn't always the right move for day one. If you already offer a welcome discount, stop giving it away for nothing. Put 1-2 questions in front of it.
"Tell us your #1 goal, get 15% off your first order."
What's your primary wellness goal? (Energy / Sleep / Immunity / Stress / Fitness / Digestion)
What format do you prefer? (Capsules / Gummies / Powder)
Two questions. That's all you need. The "sleep + gummy" customer sees gummy sleep products. The "energy + capsule" customer sees capsule energy products. You traded a free discount for two Klaviyo properties that make your entire email program smarter.
Even lighter: One question to segment your entire list.
Drop this into any mail of your welcome flow:
One tap. The answer flows to Klaviyo. Now your next email shows sleep products to the sleep segment and energy products to the energy segment. One question. Six personalized streams.
POST-PURCHASE
Catch the dropout before it happens.
Supplement churn peaks between day 30 and day 60. Customers decide "this isn't working" — even though most supplements need 4-8 weeks to show results. By the time they stop reordering, it's too late to change their mind.
A single question at the right moment changes that.
Add single-page forms at 3 points:
Day 7: "Have you started?"
Day 14 & 21: "How are you feeling?"
What happens next — based on their answers:
"Forget sometimes" →
Habit-building email: "Set a phone alarm for 8am. Take them with breakfast. 21 days to build a habit — you're on day 7."
"Noticing a difference" →
Cross-sell at the peak of trust: "Since [goal] is improving, you might be ready to add [complementary product]."
"Not feeling anything" →
Expectation-setting email: "Most people notice changes with [ingredient] between week 4 and week 6. Here's what to look for."
"Had a negative reaction" →
Immediate support email. Pause promotional sends. Suggest an alternative that avoids the ingredient that caused the issue — or offer a full refund. This response alone can save a customer relationship.
Personalized replenishment emails get 41% higher CTR than generic reorder reminders.
WINBACK
Their goals changed. Your emails didn't.
Someone who bought an energy supplement in March might care about immunity by October. Or sleep by December. A generic "we miss you" email with 20% off doesn't acknowledge any of that. A re-profiling form does.
The questions:
Goals change. What matters most to you now? (Multi-select, max 2)
What stopped working for you? (Didn't feel results / Too expensive / Forgot to take them / Changed routine / Found something else)
Anything new we should know? (New dietary restriction / Different format / Changed budget / Nothing new)
What happens next:
Their updated goals from question 1 replace the old profile in Klaviyo. Someone who originally said "energy" but now says "sleep + immunity" gets a completely different product recommendation in the follow-up email. That's the point — the re-profiling resets the relationship.
Then branch on why they left:
"Didn't feel results" →
Alternative product for their updated goal. "Magnesium didn't help your sleep? L-theanine works differently — here's why."
"Too expensive" →
Smaller bundle or single-product recommendation at a lower price point. Show them they don't need a full stack to get started again.
"Forgot to take them" →
Subscription with auto-delivery so they don't have to remember. Suggest switching formats — gummies are easier to stick with than capsules for most people.
"Changed my routine" →
Fresh recommendation based on their new goals. No callbacks to what they bought before — treat it like a new relationship.
"Found something else" →
Respect it. Send one email with their updated recommendation based on new goals. If they don't engage, move to a low-frequency nurture. Don't beg.
If question 3 flagged a new dietary restriction or format change, those filter into Klaviyo too — so the recommendation email automatically excludes what doesn't fit anymore.
SEASONAL
Every quarter, your customers' priorities shift.
Immunity products spike 40% between October and February. Resolution-related supplements jump 78% in January. The brands that align their messaging to these shifts — and personalize within them — capture demand their competitors miss.
Q1: January – March
Resolutions
Form: Coupon-gated → "What's your #1 wellness goal for this year?" + 15% off
Follow-up: Goal-specific starter stack with a 12-week plan to stay on track.
Q2: April – June
Summer Prep
Form: Single-page → "Getting ready for summer — what's your focus?"
Follow-up: "Summer energy" gets B-vitamin + CoQ10. "Skin & beauty" gets collagen + biotin.
Q3: July – September
Travel & Maintenance
Form: Single-page → "What's your wellness priority on the go?"
Follow-up: Travel-size bundles by priority. Gut health gets probiotics + digestive enzymes.
Immunity & Gifting
Form: Multi-page → "Winter wellness check" + gift guide interest
Follow-up: Immune stack for no-routine customers. Stress bundle for high-stress. Gift guide for gifters.
PREFERENCES
Let them pick what they want to hear about.
Someone focused on sleep doesn't want emails about pre-workout powder. Someone who prefers gummies doesn't want capsule promotions. Without a preference center, they get everything — and eventually unsubscribe.
Goal-based content preferences
"What topics do you want to hear about?"
Email frequency
"How often do you want to hear from us?"
Works best in the welcome flow, after a big product launch or seasonal shift. New product line? Ask who's interested before you blast everyone.
LEVERAGING THE DATA
Collecting goals feels productive. Using them is what makes money.
Here's where most supplement brands stop: they run a quiz on their website, collect goals, and never use the data in email. The quiz felt like a win. But the customer who said "sleep" is still getting emails about pre-workout powder.
The other half - the half that actually drives subscriptions - is what happens in the emails after the form. When your welcome flow recommends a sleep stack because they told you that's their goal. When your post-purchase email adjusts based on their 2-week check-in. When your winback email acknowledges that their priorities shifted from energy to immunity.
How it works in klaviyo
Your sleep stack is ready
Based on your goal of better sleep, here's what we recommend:
Your energy stack is ready
Based on your goal of more energy, here's what we recommend:
The form is only half the story.
A product quiz or form that collects goals and dies in a spreadsheet wastes half of its potential. The big value isn't in the data itself, but in what your emails do with it.
Before Kinetic:
Subject: Our Best-Selling Supplements
"Shop our top picks for health and wellness. Browse vitamins, minerals, and more."
1.1% click rate. Everyone sees the same products.
After Kinetic:
Subject: Your sleep stack is missing one thing, Jamie
"You told us sleep is your #1 goal, and you've been taking magnesium for 3 weeks. Most customers who pair it with L-theanine report better results within 2 weeks. It comes in the gummy format you prefer."
3.2% click rate. The right product for the right goal.
WHERE TO START
If you build one thing from this playbook, make it this.
Add a coupon-gated form to your welcome email. Two questions: wellness goal and format preference. The discount you were already giving away now comes with two Klaviyo properties that personalize every email after it. Sleep customers get sleep products. Gummy customers see gummies.
