Guest: Joseph Siegel, Boring Ecom

Topic: Retention systems for DTC, supplements, consumables, subscriptions, lifecycle, customer experience, customer research, and AI-enabled execution

Recorded: May 9, 2026

Executive Summary

Joseph’s biggest point is that retention is not email marketing.

Email is one lever, but real retention is the full post-purchase operating system: product, packaging, inserts, onboarding, transactional emails, upcoming order flows, subscription portal UX, cancel flows, customer service, gifts, customer research, campaigns, product education, and AI-enabled execution speed.

For supplements and consumables, retention is not about reminding people to buy again. It is about making sure they use the product correctly, understand what benefits to expect, build a habit, and stay emotionally connected long enough for the product to prove itself.

The best retention programs answer four questions:

1. Does the customer know exactly how to use the product?

2. Does the customer know when to expect benefits?

3. Does the brand create memorable moments after purchase?

4. Does the brand intervene intelligently before churn happens?

Joseph’s framework treats retention like CRO. You build hypotheses, run tests, track cohort-level outcomes, and compound improvements across the customer journey.

1. Joseph’s Background

Joseph’s last full-time role was at Feastables, where he was one of the first e-commerce hires. He joined as Head of Retention, then became Director of E-commerce Growth and Retention.

After Feastables, he started a fractional retention business and worked with major brands including:

His work is focused on building retention systems from the ground up, especially for brands where repeat purchase, subscription, product education, and LTV matter.

2. Retention Is Bigger Than Email

Most brands talk about retention as if it means email and SMS. Joseph argues that is too narrow.

Retention includes:

A useful definition:

Retention is everything that happens after acquisition that increases the odds a customer uses the product successfully, remembers the brand, and buys again.

Nik’s framing was that good retention makes the brand a top-five thought in someone’s mind, or something they bring up at the dinner table. Joseph agreed and pointed to brands like Grüns, where growth only works because backend LTV and retention are strong.

3. Active Subscribers Are Not Prospects

Joseph’s first practical warning: do not email active subscribers like they are prospects.

For supplements and consumables, active subscribers already have product or are about to receive product. If you blast them with generic “shop now” emails, you can create too much product on hand. Too much product leads to skips, pauses, and churn.

What active subscribers should receive

Active subscribers should get fewer, better messages. The message should be additive, not extractive.

Good subscriber emails:

Bad subscriber emails:

Joseph’s default view: most weekly campaigns should go to non-customers, prospects, or one-time purchasers. Active subscribers should only get a handful of emails per month when the content genuinely helps them.

4. Upcoming Order Emails Are a Major Retention Lever

Most subscription brands treat upcoming order emails as transactional warnings:

“You have an order coming in three days. You will be charged $200.”

That message reminds the customer of the cost. It often triggers cancellation.

Joseph’s recommendation is to flip the script. The upcoming order email should remind the customer of progress, not payment.

Weak version

Strong version

Segment by order cycle

A major mistake: sending the same upcoming order email to every subscriber.

Recommended segmentation:

Order 1 → Order 2

Goal: reduce early churn and reinforce consistency.

Message themes:

Order 2 → Order 3

Goal: connect continued usage to emerging benefits.

Message themes:

Order 3 → Order 4

Goal: deepen the routine and identity.

Message themes:

Order 4+

Goal: treat as loyalist, not generic subscriber.

Message themes:

5. Transactional Shipping Emails Are Underused Retention Real Estate

Joseph believes transactional emails are one of the most overlooked retention assets.

These include:

These are among the highest-opened emails a brand sends, but many brands leave them inside Shopify. That limits data, design, and strategic control.

Move these emails into Klaviyo or another lifecycle platform using tools such as:

What to do differently

Do not make the email purely about shipping.

Use the high-attention moment to teach:

Push the tracking/order details lower in the email. The customer should still get the transactional information, but the top of the email should increase excitement and confidence.

By the time the product arrives, the customer should already know how to use it and why it matters.

6. The First 14–30 Days Are Critical

For consumables and supplements, the early window determines whether the customer forms a habit or churns.

Customers churn early because:

The first month should be designed like onboarding, not like a generic post-purchase sequence.

First-month onboarding should answer

7. Product Inserts Should Be a Measurable Retention Channel

Joseph is critical of generic inserts. Many brands treat inserts as a throw-in: a founder note, thank-you card, generic discount code, or vague brand story.

The issue is not that inserts are bad. The issue is that most inserts have no retention job.

Bad insert

Good insert

A good insert helps the customer use the product better and stay longer.

It can include:

Education plus emotional outcome

Nik asked whether inserts should focus on education or product/emotional outcome. Joseph’s answer: ideally both.

The insert should explain what drives the benefit, but it should also paint the picture of what the customer may experience if they use the product correctly.

Example:

“Take daily for 12 weeks. In consumer studies, users reported X, Y, and Z benefits.”

That gives the customer a blueprint. It tells them what to do and why to keep going.

8. Examples of Strong Product Inserts

Ultra

Ultra uses the insert to explain different levels of product usage. If a customer wants to feel it more, they can take more pouches. If they want the maximum effect, they can take three.

This teaches the customer how to tune the experience.

Alice Mushrooms

Alice sells functional chocolates. Joseph mentions an insert that explains two different use cases:

This connects product usage to emotional outcome.

Mars Men

Joseph calls Mars Men one of the best product insert examples he has seen.

They include a physical habit tracker, likely over 30/60/90 days. Customers are prompted to complete it daily, take a photo when finished, and submit it to receive a free month.

Why it works:

This is the key idea:

The insert is not a piece of paper. It is a retention mechanic.

9. Packaging and Unboxing Matter

Joseph believes premium unboxing helps retention because it creates a more memorable brand, even though it is hard to A/B test.

His example: IM8.

The IM8 unboxing experience includes:

Why packaging helps

Packaging can:

Packaging as advertising

Nik and Joseph also discuss packaging as a physical billboard.

In cities and apartment buildings, branded boxes and mailers are seen by many people. Examples mentioned:

A branded mailer may be worth the incremental cost because it functions as both unboxing experience and passive advertising.

10. Gifts Should Improve the Customer Experience

Gift strategy comes up often in Joseph’s work.

His main rule:

A gift should be additive to the customer experience based on the product they bought.

Bad gifts feel cheap, generic, or disconnected. If a brand hypes a “mystery gift” and sends something obviously low-value, it can backfire.

Good gift criteria

A good gift:

Grey Matter example

Grey Matter gives customers a frother or shaker bottle.

For powdered products, especially in cold water, clumping can hurt the product experience. A shaker bottle makes the product easier and better to consume.

That gift directly improves retention because it helps the customer get a better experience from the core product.

Gift cost rule

Joseph’s guideline:

If the gift costs too much, the retention lift has to be large enough to justify it.

11. Delayed Gifts Can Pull Customers Forward

Nik highlights gifts on a delay, and Joseph agrees they can be powerful.

Delayed gifts work because they give the customer something to stay for.

Examples:

The strategic value is that the reward comes after the behavior the brand wants: continued use, repeat orders, and habit formation.

12. Digital Gifts and AI-Native Bonuses

Nik shares examples from Hint, where gifts-with-purchase worked well without extra discounting.

Examples:

The logic: the partner sees the recipient as an acquisition opportunity, so the brand can offer high perceived value at low direct cost.

Joseph believes brands can now build their own versions with AI.

Possible AI-native retention gifts:

This can replace expensive partnerships with proprietary digital value.

13. Masterclasses and Interactive Onboarding

Joseph is exploring masterclass-style onboarding through tools like Typeform.

Email has limited attention. Many customers only read the hero section. A Typeform-style experience can make the customer actively click through education.

What an onboarding masterclass can teach

Why it works

14. The Most Important Retention Flows

Nik asks which flows brands need for higher retention.

Joseph does not default to “welcome series.” Welcome flows matter, but most of the retention opportunity happens after purchase.

Priority flows

1. Transactional shipping flows

High open rates. High attention. Perfect for education and expectation-setting.

2. Post-purchase onboarding

Especially first 14–30 days. Teach usage, timeline, and habit.

3. Upcoming order flow

Segment by order cycle. Make it about progress, not payment.

4. Cancel prevention flow

Collect cancellation reason, offer relevant treatment, and route customers through self-serve save paths.

5. Subscription winback

Recover customers after churn with more than generic discounts.

6. VIP/top-customer winback

Do not send your best customers into the same generic winback flow. Invite them into a more personal feedback loop.

Example:

“You’ve been with us for four months and you’ve been one of our best customers. We’d love to understand what changed.”

The goal is to learn before selling.

15. Customer Interviews Are a Retention Data Layer

Joseph uses customer interviews to understand behavior, churn, and language.

Process

1. Send invite email

2. Use a mini-survey to qualify candidates

3. Confirm they consent to being recorded

4. Record the call

5. Store transcript in Fireflies, Otter, or similar

6. Match transcripts with Outer Signal data

7. Add customer review data

8. Build ICP segments and messaging insights

Joseph likes Fireflies because it integrates with Claude through MCP.

Key insight from interviews

Customers often cancel not because they dislike the product, but because they have too much product.

Some customers give product to friends and family. From the dashboard, it looks like churn. In reality, they may still love the product.

That changes the retention response. The issue is not always persuasion. Sometimes it is cadence, dosage, quantity, or subscription flexibility.

How to use interview data

Use customer language in:

Joseph specifically extracts customer quotes and uses them across ads, website, and emails so the brand speaks in the customer’s language.

16. Campaigns Can Lower CAC

Joseph does not manage campaigns directly, but he helps brands analyze their impact.

He has found that campaign sends to non-customers can correlate with lower CAC on those days.

Across several brands, campaign days showed roughly a 10–11% CAC drop. He frames this as anecdotal, but worth testing.

Analysis method

Build a sheet with:

Analyze at least 90 days.

Look for:

Strategic takeaway

Campaigns are not just an email revenue channel. They can support paid media by warming demand and improving conversion efficiency.

17. The Best Brands Send Campaigns

Joseph says strong brands send campaigns. Brands that do not are usually constrained by bandwidth or weak email teams.

A non-customer list that never receives campaigns becomes dormant. Once dormant, it becomes harder to reactivate.

Zombie CRM risk

Nik asks about a brand with:

Joseph says that is a tough spot. The brand should not have let the list go cold.

An email list is an asset only if it is kept alive. If ignored, it depreciates.

How to prevent it

18. Metrics That Matter

Joseph does not focus heavily on email open rates because modern tracking is distorted.

His retention metrics are business-level metrics.

North Star: order retention

Joseph distinguishes:

He sees order retention as the North Star.

A core question:

Of customers who ordered this month, what percent order again next month?

This matters for payback and LTV.

LTV windows

Track:

Investors care about 12- and 24-month retention because they indicate brand and product quality.

Churn metrics

Track churn by:

Churn by order cycle

Early order cycles have the highest churn.

Typical pattern:

This tells you where to focus: early subscribers need the most intervention.

Cancel-flow metrics

Track:

Even if skippers do not perfectly retain, a 60% reorder rate among would-be cancelers can still be a win.

Email metrics

Open rate is increasingly a vanity metric. Click rate still matters but is imperfect. Joseph says a “strong-ish” click rate may be around 0.5% to 1%, though many brands are seeing lower.

19. Promo Tab Avoidance

Joseph mentions tools like:

He says these tools can add hidden text-like content to the HTML of emails that users do not see but inbox providers may read. The goal is to make the email appear more transactional, such as a privacy policy update, and increase the odds of landing in the primary inbox.

Important caution

This is a tactic Joseph describes. Brands should evaluate platform rules, compliance, and deliverability risk before using hidden-text tactics. The safer strategic lesson is that deliverability is now an active optimization area, not a passive one.

20. Customer Service Is a Retention Lever

At the end, Joseph emphasizes that customer service can be a huge lever or a huge detriment.

Example: a subscriber writes in and says they want to cancel.

A weak customer service response:

“Okay, you’re canceled.”

That creates unnecessary churn.

Better approach

1. Respond with empathy

2. Ask or identify the cancellation reason

3. Offer a relevant treatment

4. If they still want to cancel, send them to self-serve portal

5. Let the cancel-prevention flow attempt to save them

This creates multiple chances to save the customer without being shady.

Why self-serve matters

If support cancels immediately, the customer bypasses:

Joseph recommends that, when appropriate, customer service should route users to the self-serve cancellation portal after trying to help.

Track churn by admin/support agent

Subscription platforms can show churn by admin or user. Brands should inspect whether cancellations are mostly happening through self-serve users or through customer service agents.

If support agents are canceling too quickly, that can compound into meaningful churn.

21. Product Quality Sets the Retention Ceiling

Joseph is clear that retention cannot fully overcome product issues.

At Feastables, retention was poor when he joined. The key learning was that only about 3% of the audience cared about “better-for-you chocolate.”

That insight helped lead to a reformulation and rebrand, shifting more toward milk chocolate instead of dark chocolate.

After the product and brand changes, retention cohorts improved significantly, with more than 100% improvement across early months after initial order.

Key lesson

Retention strategy cannot compensate forever for a product that does not match what customers want.

Product matters. Category matters. Use case matters.

A chocolate brand will usually not have the same retention ceiling as AG1 or IM8 because chocolate is not necessarily a daily supplement habit.

The goal is to reach the top of the retention ceiling for your category, not blindly compare yourself to a different category.

22. Avoid Shady Rebill Tactics

Joseph warns against forcing customers into second orders through shady tactics.

You may improve month-two retention on paper, but often you see a large drop from month two to month three because customers feel tricked or overloaded.

Bad retention:

Good retention:

23. Patterns of the Best Brands

Nik asks what Joseph sees among the fastest-growing, fastest-moving brands.

Joseph’s answer:

1. Speed of execution

2. Very high quality bar

3. High testing velocity

4. Willingness to push boundaries

5. Serious AI usage

The best brands approach retention like CRO:

Do not blindly copy winners

Joseph cautions that e-commerce brands copy each other too much.

Example: Grüns’ buy box may work for Grüns, but Joseph has tested similar approaches across other brands where it did not work.

Take inspiration, but test against your own audience.

24. AI Usage Separates Fast Brands From Slow Brands

Joseph says top brands are pushing teams to use AI more aggressively.

The mindset:

Whatever you think your output speed is, you are not using AI enough.

Someone who is 70% as strong as you but 100x better at AI can beat you.

AI use cases mentioned

Joseph uses:

Use cases:

Nik shares examples:

Key AI insight

The real power is not asking AI isolated questions. It is giving AI context from the business and connecting it to data sources.

The best AI systems know:

Then they can suggest stronger tests and execute faster.

25. Generative Email

Nik asks about generative emails.

Joseph has seen tools in the market but has not seen a one-click platform that reliably creates perfect brand emails.

However, he is already using AI as the first step in email creation.

Practical current workflow

1. Use AI to create email skeletons

2. Batch-generate concepts and structures

3. Pass to designers and copywriters

4. Fill in brand-specific gaps

5. Send to large lists

Joseph says teams can now create 50 solid email skeletons in around 30 minutes, dramatically reducing production time.

26. Voice AI and Customer Interviews

Nik brings up new OpenAI voice models that can hold instant, emotionally expressive conversations.

Joseph believes customers eventually will not care if the interviewer is AI, especially if they get something valuable at the end.

Implication

Brands may soon be able to conduct scaled customer interviews through AI voice agents.

Use cases:

This could make customer research much cheaper and more continuous.

28. The Big Strategic Takeaways

1. Retention is a system, not a channel

Email matters, but retention touches every part of the post-purchase experience.

2. The customer must know how to succeed

For supplements, consistency and expectations are everything. If customers do not know how to use the product, they churn before the product has a chance to work.

3. Upcoming order emails should sell progress, not warn about charges

The worst version reminds people they are about to spend money. The best version reminds them why they started.

4. Inserts and packaging are underused

A product insert can be a retention mechanic. Packaging can be a memory device and a billboard.

5. Gifts should remove friction

The best gifts make the product easier or better to use.

6. Customer interviews reveal what dashboards miss

A cancellation may mean “I have too much product,” not “I hate the product.” That distinction changes the response.

7. Campaigns can support paid efficiency

Email campaigns to non-customers may lower CAC by warming demand.

8. Order retention is the metric

Subscriber retention alone is not enough. Measure whether customers actually order again.

9. Product sets the ceiling

Retention work compounds a good product. It cannot permanently save a product that misses the customer’s desired use case.

10. Speed wins

The best brands test faster, execute better, and use AI more deeply.
