3 things nobody tells you about ecommerce email marketing case studies

What to take away

Ecommerce email marketing case studies usually get written as success stories. The three lessons below come from the other direction: public FTC enforcement records. The records name Publishers Clearing House, Vonage, Amazon, Adobe and Age of Learning. Each lesson is a thing the case study format tends to leave out.

Lesson 1: the Publishers Clearing House record is an allegation, not a finding

The FTC's announcement about Publishers Clearing House marketing practices describes a proposed order following allegations about misleading sweepstakes flows, surprise fees, data-policy statements, and deceptive emails.

The agency described messages that implied a final step was required and routed people back into sales flows. Under the June 2023 settlement, PCH agreed to pay $18 million to consumers.

A proposed order is not a proven finding. A case study that flattens the two teaches the wrong lesson. Copy the procedural label exactly: complaint, proposed order, final order or consent order.

Test the subject line, preview text, sender, body, and buttons as one unit. Also test the destination, checkout, terms, and follow-up as one unit.

A technically accurate sentence can still mislead when hierarchy or repetition pushes a different meaning. A full ecommerce email marketing checklist covers each test point and why it belongs there.

Lesson 2: Vonage, Amazon and Adobe put cancellation friction in your reminder flow

The FTC's announcement of its Vonage settlement describes allegations about a dark-pattern cancellation process, unexpected fees, and continued charges. The November 2022 settlement was $100 million. Vonage is a communications provider, not a retailer, which is exactly why the lesson travels.

The FTC sued Amazon in June 2023 over Prime enrollment and cancellation. That case settled in September 2025 for $2.5 billion: a $1 billion civil penalty and $1.5 billion in customer refunds.

The FTC sued Adobe in June 2024 over early termination fees and a cancellation path that took more steps than signup. Age of Learning, the company behind ABCmouse, paid $10 million in 2020 to settle charges about enrollment and cancellation.

The FTC's own click to cancel rule, finalized in October 2024, was vacated by the Eighth Circuit in 2025. Section 5 case law on unfair or deceptive practices still does the work.

Subscription reminder emails sit upstream of the cancellation page. If a reminder misstates the plan or the date, the customer arrives at cancellation already misled.

For each case review, record the source date and procedural language. Also record the affected journey, claimed harm, and remedy. Then record the comparable store process and existing control. Finally, record these remaining items:

Legal counsel reviews actual requirements and risk. Marketing owns the operational evidence it can test.

Lesson 3: your own case study claims need a substantiation file

The FTC advertising substantiation policy requires a reasonable basis before objective advertising claims go out. That applies to the performance numbers in your own case studies, as well as to vendor claims you quote.

The FTC guidance for marketers using reviews warns about fake feedback, selective requests, conditioned incentives, hidden relationships, and paid rankings. The FTC's review rule took effect on October 21, 2024. Each violation carries a civil penalty that was set at $51,744 when the rule took effect.

Separate provider claims, customer statements, measured records, and independent findings. Record selection criteria, commercial relationships, product version, and study population. Record method and missing evidence.

Reproduce one material claim with local data before recommending a provider. If the method is unavailable, label the item a lead for testing rather than a verified result.

Keep that evidence record beside the decision, so a reviewer can reproduce the reasoning without relying on memory. More common ecommerce email marketing questions come up at this stage than at any other.

Common questions

Are these cases proof that our program is unlawful?

No. They are public examples that surface questions and control gaps. Qualified counsel must analyze your store's facts against current law. The FTC's own procedural wording is the only reliable description of each case's status.

Which enforcement actions should an ecommerce email team track?

Publishers Clearing House, Vonage, Amazon, Adobe and Age of Learning all turned on enrollment, billing, cancellation or claim language that also shows up in email. Read the FTC press releases and the underlying orders, not the blog summaries.

What should a case study cite?

Cite the specific complaint, order, court record, or agency page, and preserve its procedural wording exactly. A case study that cites a blog summary of an order instead of the order itself cannot be audited later.

How often should cases be reviewed?

Review relevant developments on a defined cadence, and again whenever the store changes subscriptions, promotions, cancellation, or lifecycle messaging. Those changes are what move a store toward or away from the patterns above.
