2026 BCG Black Friday Study: Are Discounts in Promotional Emails Trustworthy?

What the study measures

BCG’s year-end sales research reports consumers’ views on Black Friday discounts and promotion fatigue. Those are attitude measures: they tell us what respondents said or felt under the study’s stated questions and method. They do not independently inspect every retailer’s advertised prices or verify the emails shoppers receive.

That distinction matters when a headline or social post turns a survey finding into a universal verdict. A reported level of trust belongs to the respondents and question wording described by BCG. It should not be restated as “American shoppers know Black Friday deals are fake,” nor as proof that every promotion is misleading. The BCG research page is the authority for the study’s scope and method. Use its market, respondent, and question definitions whenever quoting a percentage. If those qualifiers are missing from a shortened summary, do not fill the gaps with assumptions.

A survey result can still be useful. If shoppers report skepticism or fatigue, that is a signal to be selective about subscriptions and to verify offers rather than accepting a discount label at face value. It is not a substitute for checking the offer itself.

Discount trust and price verification

The phrase “trust in Black Friday discounts” sounds like a statement about prices. In a consumer study, however, it describes respondents’ attitudes unless the research separately audits products and price histories. A trust percentage is not a count of verified deals.

This is the key boundary for anyone reading about Black Friday promotional emails:

A shopper may distrust discount claims while a particular offer remains valid. Another shopper may trust a familiar store while missing a condition such as a minimum spend, excluded product, membership requirement, or limited delivery region. Neither case can be resolved by an attitude survey.

For a specific purchase, start from the retailer’s official website or app. Find the current offer page rather than relying on a forwarded message. Read the eligibility rules, exclusions, and end conditions. Add the item to your cart and inspect the final total before paying. The FTC’s online shopping guidance also recommends checking the seller and understanding the terms before purchase.

A discount label is a claim to verify, not proof of savings.

Offer evidence and email evidence

There are two separate questions: whether an offer is worthwhile and whether a message is safe to act on. A correct discount can appear in a deceptive email copied from a real promotion. A legitimate marketing email can also advertise an offer with conditions that make it irrelevant to your cart.

For an offer, check the current retailer page and checkout. For a message, avoid opening unexpected links or attachments. Navigate to the retailer independently if the email asks you to sign in, resolve a delivery problem, or claim a refund. The FTC’s phishing guidance explains warning signs and safer ways to respond.

This separation prevents a common reasoning error: “The survey says consumers distrust discounts, so this email must be false,” or the reverse, “The email uses a familiar store logo, so the discount must be real.” Neither follows. The study describes consumer sentiment; the retailer’s current terms and the message’s origin are separate evidence.

Promotion subscriptions and inbox value

The 2026 Black Friday promotional emails you receive are useful only if the offers match your shopping habits and you can manage the volume. A survey’s finding about trust does not mean you should subscribe to more stores to compensate, or unsubscribe from every store before checking whether its messages help you.

Consider one shopper who buys household supplies from the same retailer several times a year. A promotional subscription may help them notice a relevant sale. Another shopper is signing up once for a discount at a store they may never revisit. Sending every future campaign to a primary inbox may cost more attention than the one-time offer is worth.

Use this decision list:

• If you regularly compare offers from a retailer and review its emails, keep the subscription, but route marketing mail away from order and account messages.
• If you want one sign-up offer and do not expect to shop there again, use a separate promotional address only if you can access it for the offer and any follow-up you need.
• If the retailer account will store order history, returns, warranties, or payment details, use a durable address or verified long-term forwarding instead of an address you may lose.
• If you no longer read the campaigns, unsubscribe or create a mail rule. Do not keep a subscription merely because a discount might appear someday.
• If a message asks for sensitive details or urgent account action, do not use its link; go to the retailer independently and check your account there.

The FTC says covered commercial email must provide an opt-out method and that senders must honor opt-out requests within 10 business days. Its CAN-SPAM compliance guide also says the opt-out mechanism must remain available for at least 30 days after the message is sent. Those are compliance rules, not a guarantee that every unwanted message will stop immediately. If mail continues, use your email provider’s spam controls and avoid engaging with suspicious messages; the FTC explains ways to get less spam.

Mail continuity and account risk

A marketing subscription is not the same thing as a shopping account. The promotional address can be treated as an inbox-management choice. The account address may be needed for password resets, order tracking, returns, refunds, warranty claims, or proof of purchase.

That difference changes the cost of losing access. If a temporary address expires or becomes unavailable, a store may still send an order update there. You could also be unable to receive a recovery link later. A separate address helps sort messages; it does not prove a retailer will keep your information private, prevent a data breach, or protect you from phishing.

For important shopping accounts, choose an address you can access for the life of the account. An email alias or forwarding address can help separate retailers while keeping a route to your primary inbox, but only if the forwarding service is reliable and you understand how to maintain it. Our guide to disposable addresses versus aliases explains the difference. If you already use a short-lived inbox, review how mailbox lifespan affects access before relying on it for an account you may need again.

Reading the evidence without overclaiming

The BCG consumer study is relevant to the question “How do respondents view Black Friday discounts?” It is not a rating of individual retailers, and it does not certify the price in a 2026 Black Friday promotional email. Keep those claims separate when discussing the research with other shoppers.

When a report gives a percentage, carry its denominator and wording with it. “Among respondents who answered this question” is not interchangeable with “all American consumers.” If the study covers a particular market or respondent group, keep that qualification attached. Do not infer an unreported sample size, fieldwork window, or survey method from the publication date.

For consumers, the next step is simpler than trying to turn a sentiment finding into a price prediction. Decide which stores deserve an inbox slot. Check each offer against the retailer’s current page and the final checkout amount. Keep messages needed for transactions and account recovery on an address you will continue to access.

FAQ

What the BCG trust finding means

BCG’s finding concerns surveyed consumers’ stated views on Black Friday discount trust. Its meaning depends on the exact question, respondent group, market, and methodology stated in the official research. It does not say that every shopper distrusts every deal. It also does not independently test retailer prices or authenticate marketing emails.

What a trust result says about prices

A trust result is not a price-history audit. It cannot show whether an item’s earlier price was higher, whether the advertised discount is accurate, or whether the offer applies to a particular cart. Check current retailer terms and the checkout total. Treat the survey as context for consumer attitudes, not as product-level evidence.

Whether a study can authenticate a promotion email

No. A consumer survey cannot confirm the sender, the legitimacy of a link, or whether a coupon will work. If a message is unexpected or asks you to act urgently, avoid its links and open the retailer’s official site independently. Verify the offer there, then compare its terms with what appears at checkout.

Separating marketing from order messages

Route promotional subscriptions to a separate inbox, folder, or address you can continue to access while you want those offers. Keep shopping accounts, receipts, delivery updates, returns, refunds, and recovery messages on a durable address or verified long-term forwarding route. A separate address organizes mail; it does not guarantee privacy or security.

If you are choosing an address for a one-off promotion, first decide whether you need only marketing messages or also need future access to an account, order, or return. Our guide to choosing an address for sign-ups can help you compare those needs. Use a short-lived option only for mail that does not need to remain reachable; keep order and recovery messages on an address you can retain.
