# Do Client Gifts Actually Work? What the Research Says, and What It Doesn't

Client gifts work in the sense researchers can test: randomized field experiments show small, unexpected gifts raise tips and donations. No published randomized study we found tests whether a small firm's holiday gifts raise its revenue; client-gift figures are surveys of what recipients say.

*We sell a $35 logo mug gift box, printed, packed and shipped to each person's address, so we have a stake in this answer. This page grades each study by the strength of its evidence, names who ran each survey, and says what the research doesn't show.*

**Key facts**
- **+17% and +75%:** how much more often people donated when a charity letter held a small or a large gift, in a randomized mailing of about 10,000 letters ([Falk, 2007](https://ideas.repec.org/a/ecm/emetrp/v75y2007i5p1501-1511.html), *Econometrica*).
- **17.8% vs 15.1%:** the mean tip when a server gave each diner a piece of chocolate with the check, against none, across 92 dining parties ([Strohmetz et al., 2002](https://ecommons.cornell.edu/entities/publication/49ee9efd-b182-49af-8346-a3c63391a552), Experiment 1).
- **46%** of gift recipients in an online poll of 1,547 professionals said year-end gifts from vendors made them "more likely to continue working together", and companies with fewer than 100 employees were "the most likely to be influenced" ([business.com](https://www.business.com/customers/corporate-gift-study), an online poll, October 2022).
- **Price isn't the lever:** givers expect pricier gifts to be appreciated more; recipients report no link between price and appreciation ([Flynn & Adams, 2009](https://www.gsb.stanford.edu/faculty-research/publications/money-cant-buy-love-asymmetric-beliefs-about-link-between-gift-price)).

## The Evidence Ladder: What Each Kind of Study Can Prove

A randomized experiment can show that a gift caused a change. A survey shows what people say. Here is every study on this page, the strongest kind of evidence first.

| Kind of evidence | Study | Design and sample | What it found | What it can't tell you |
|---|---|---|---|---|
| Randomized field experiment | [Falk (2007)](https://ideas.repec.org/a/ecm/emetrp/v75y2007i5p1501-1511.html), *Econometrica* | About 10,000 charity solicitation letters; a third each with no gift, a small gift or a large gift, assigned at random | Donations came 17% more often with the small gift and 75% more often with the large one | Donors to a charity, not clients |
| Randomized field experiment | [Strohmetz, Rind, Fisher & Lynn (2002)](https://ecommons.cornell.edu/entities/publication/49ee9efd-b182-49af-8346-a3c63391a552) | Restaurant tables: 92 dining parties in Experiment 1, 80 in Experiment 2 (20 per condition) | Candy with the check raised tips, and how it was offered mattered | Tips on one bill, not repeat business |
| Longitudinal field experiment with spending data | [Marchand, Paul, Hennig-Thurau & Puchner (2017)](https://doi.org/10.1177/1094670516682091), *Journal of Service Research* | 1,950 airline customers, four gift designs, matched to the airline's own customer records | The gifts' effect on spending ran entirely through customers' sense of the airline's investment in them and their intention to buy again | A large airline, not a small firm |
| Controlled field experiment, then a replication with sales | [Beltramini (1992)](https://doi.org/10.1007/BF02723479); [Beltramini (2000)](https://doi.org/10.1080/00913367.2000.10673610) | A company's customers got a more expensive gift, a less expensive gift or none; surveyed before and after, with actual sales tracked in 2000 | Business gifts were "an effective part of a marketer's overall marketing communications strategy" | The effect sizes aren't in the abstracts |
| Lab experiment plus a field survey | [Palmatier, Jarvis, Bechkoff & Kardes (2009)](https://doi.org/10.1509/jmkg.73.5.1), *Journal of Marketing* | A laboratory experiment and a dyadic longitudinal field survey | Gratitude helps explain how relationship investments raise "purchase intentions, sales growth, and share of wallet" | Relationship investments in general, not gifts alone |
| Experiments on gift price | [Flynn & Adams (2009)](https://www.gsb.stanford.edu/faculty-research/publications/money-cant-buy-love-asymmetric-beliefs-about-link-between-gift-price) | Three studies; price and roles manipulated or measured in the field | Givers expected pricier gifts to be appreciated more; recipients reported no such link | Feelings of appreciation, not business results |
| Scenario study | [Wafa, Jantan & Chow (1999)](https://e-journal.uum.edu.my/index.php/mmj/article/view/8735) | 143 purchasing executives reading gift scenarios | Indebtedness and perceived manipulation affected their intention to reciprocate | Imagined gifts, not real ones |
| Surveys, mostly by gift sellers | business.com, Ready Set Gift, Sendoso, Snappy (table below) | Surveys of 501 to 1,547 people | Recipients say gifts make them more loyal or closer to the sender | Self-reported; none measured sales |

## What the Field Experiments Found

**Charity letters: a gift raised giving, and a bigger gift raised it more.** Armin Falk's team sent roughly 10,000 solicitation letters for a charity. One third held no gift, one third a small gift, one third a large gift, and "Treatment assignment was random." Compared with no gift, "the relative frequency of donations increased by 17 percent if a small gift was included and by 75 percent for a large gift" ([Falk, 2007](https://ideas.repec.org/a/ecm/emetrp/v75y2007i5p1501-1511.html)). This is the cleanest evidence that an unasked-for gift changes behavior. It is also a reminder that, in this study, the larger gift did more.

**Restaurant candy: the way it's given matters.** In Experiment 1, across 92 dining parties, the mean tip was 17.8% when each diner got a piece of chocolate with the check and 15.1% with none. The servers used "a fancy, foil wrapped piece of chocolate", chosen "to differentiate this token gift from the inexpensive wrapped mints that are often provided by restaurants." Experiment 2 (80 parties, 20 per condition) varied the candy and the delivery:

| Condition (Experiment 2) | Mean tip |
|---|---|
| No candy | 18.95% |
| One piece each | 19.59% |
| Two pieces each, handed over together | 21.62% |
| One piece, then a second offered as the server turned to leave | 22.99% |

The same two pieces did best when the second came as an extra, unexpected gesture. The authors argue "that reciprocity is a stronger explanation for these findings than either impression management or the good mood effect" ([Strohmetz et al., 2002](https://ecommons.cornell.edu/entities/publication/49ee9efd-b182-49af-8346-a3c63391a552)). Their conclusion on practical value: "Inexpensive and personalized gestures of gratitude such as giving one's customers candy at the end of a meal could mean millions of dollars of extra income annually for the nearly two million servers in the U.S."

**Airline customers: gifts moved spending through the relationship.** Marchand and colleagues combined "a longitudinal field experiment with internal customer database information" for 1,950 airline customers and tested four gift designs. They found "the impact of gifts on customer spending is fully mediated by customer perceptions of perceived relationship investment and repurchase intention" ([Journal of Service Research](https://doi.org/10.1177/1094670516682091)).

**Business customers: a controlled test, then a replication with sales.** Richard Beltramini's 1992 study is titled "A Controlled Field Experiment". His 2000 replication surveyed a company's customers before and after "being sent a more expensive gift, a less expensive gift, or no gift at all", tracked their actual sales, and concluded that "business gift-giving represents an effective part of a marketer's overall marketing communications strategy" ([Journal of Advertising](https://doi.org/10.1080/00913367.2000.10673610)). The abstract gives no effect sizes, so we quote none.

## Why Gifts Work: Reciprocity and Gratitude

**Reciprocity.** People feel a pull to return a favor. The restaurant study's authors chose it over two rival explanations, wanting to look generous and simply being in a good mood.

**Gratitude.** Palmatier and colleagues found, in a lab experiment and a two-sided field survey, that "relationship marketing investments generate short-term feelings of gratitude that drive long-lasting performance benefits" ([Journal of Marketing](https://doi.org/10.1509/jmkg.73.5.1)). A client gift is one kind of relationship investment.

Both can backfire if the gift looks like a lever. In a study of 143 purchasing executives, "the buyers' perceptions of the level of manipulation associated with the gift" affected whether they intended to reciprocate ([Wafa, Jantan & Chow, 1999](https://e-journal.uum.edu.my/index.php/mmj/article/view/8735)). A thank-you with no ask attached avoids that.

## What Client-Gift Surveys Say, and Who Ran Them

These client-gift numbers are surveys: what recipients say. Three of the four come from companies that sell gifts or gifting software.

| Survey | Who ran it | Sample | What respondents said |
|---|---|---|---|
| [business.com Corporate Gift Study](https://www.business.com/customers/corporate-gift-study), Oct 2022 | business.com, a publisher; online poll | 1,547 professionals | 46% of gift recipients said year-end vendor gifts made them "more likely to continue working together"; companies with fewer than 100 employees were the most influenced; 54% had thrown a gift away without using it |
| [Ready Set Gift survey](https://www.taylor.com/research/workplace-gift-giving), published by Taylor, Apr 2, 2025 | Ready Set Gift, a gift company | 501 respondents; 12.6% had received a gift as a client and 23.6% in both roles | 79% "felt more loyal to the business from which they received a client gift"; 83% "are more inclined to do business with the gifter in the future" |
| [Sendoso survey](https://www.martech360.com/news/media-growth/sendoso-gifting-survey-finds-majority-of-recipients-want-gifts-from-small-businesses-local-merchants-and-minority-owned-businesses), Nov 2022 | Sendoso, a gifting platform | "more than 1200 respondents" | 83% of those who got a corporate gift in the past two years said it "made them feel closer to the company who sent it" |
| [Snappy 2023 Holiday Gifting Report](https://www.snappy.com/press-releases/new-study-reveals-75-of-employees-hope-to-receive-a-gift-from-their-company-this-holiday) | Snappy, a gifting platform; fielded by Propeller Insights, Sept 2023 | 1,527 US adults, online | 55% "reflect fondly" on the giver when using a gift; 63% "would rather receive no gift than a poorly chosen one" |

**How to read this table.** Every figure is self-reported, and none of these surveys measured whether a gift changed what anyone bought. The business.com poll is the only one not run by a gift seller, and it is also the most mixed: the poll in which 46% said vendor gifts made them "more likely to continue working together" also found 54% had thrown a gift away unused.

## What the Research Doesn't Show

- **That client gifts raise a small firm's revenue.** We found no published randomized study of it. The closest designs are an airline's 1,950 customers and Beltramini's single company, whose effect sizes aren't in the abstracts.
- **That smaller is always better.** Falk's large gift outperformed the small one on donations. Flynn and Adams found recipients' appreciation wasn't linked to price. Both are true: they measured different things, giving money back versus feeling thanked.
- **That a tip, a donation and a client relationship work the same way.** The strongest experiments are in restaurants and charities. The mechanism, reciprocity, is the same; the size of the effect on a client relationship is unknown.
- **That recipients do what they say.** "More likely to continue working together" is an answer to a poll, not a renewal.

## What the Evidence Suggests for a Client Gift (Our Reading)

Not a finding, our reading of the studies above:
- **Unexpected beats expected.** The extra candy offered on the way out did best in the restaurant study.
- **Personal beats expensive.** Recipients' appreciation wasn't linked to price ([Flynn & Adams, 2009](https://www.gsb.stanford.edu/faculty-research/publications/money-cant-buy-love-asymmetric-beliefs-about-link-between-gift-price)), and a specific thank-you lands better than writers expect (Kumar & Epley, 2018).
- **Useful beats impressive.** Givers lean toward desirable gifts while "receivers prefer to receive more practical gifts" ([Baskin et al., 2014, via Yale Insights](https://insights.som.yale.edu/insights/study-explains-pitfalls-in-gift-giving)).
- **No strings.** Perceived manipulation weakens reciprocity, and business.com's respondents said "prominently branded items felt more like ads than tokens of appreciation". How to keep a logo small: [logo or no logo](https://personalizedgiftsdelivered.com/why-gifts-work/logo-on-client-gifts).

## How to Test Whether Your Client Gifts Work

Beltramini's design compared customers who got a gift with customers who didn't. You can copy that on a small scale without leaving anyone out, by sending the same gift at two times (our suggestion, not a study):
1. Pick one tier of clients you'd gift anyway.
2. Split the list at random into a "now" half and a "90 days later" half.
3. Send the "now" half their gift. Note replies and thank-yous within two weeks, then referrals, renewals and reviews within 90 days, for both halves.
4. Compare the halves, then send the second half the same gift.

With 20 or 40 clients, chance alone can swing the result, so read it as a hint.

## What to Know Before You Order

- **No promised return.** We claim no sales return for any gift, ours included. What we state is what the box holds and what it costs, below.
- **Gift limits.** Each box is $35, delivered. Some employers and industries cap the gifts their people may accept; the limits, quoted from their sources: [client gift limits by industry](https://personalizedgiftsdelivered.com/gift-rules/client-gift-limits-by-industry).
- **The treats.** LINDOR truffles contain milk, soy and barley malt (gluten); read the labels.
- **Where we ship.** The lower 48 states and Washington, DC, except Texas for now. No Alaska, Hawaii, Puerto Rico, other US territories, APO/FPO or international. The order page flags any row we can't ship to, so you can fix it or take it out.

## Where Personalized Gifts Delivered Fits: A Useful Object, a Treat and a Note, in One Box

Our reading of these studies points to a useful object, a treat and a personal note, with no ad attached. Each Personalized Gifts Delivered box holds all of them:
- **A useful object.** An 11 oz white ceramic mug with your logo printed small (Small, up to 1½ in wide, is the default). In ASI's 2026 Ad Impressions Study, a promotional-products industry survey, 87% of end-users said they would keep a branded drinkware item "because of its usefulness" ([ASI](https://members.asicentral.com/news/strategy/june-2026/asi-s-2026-ad-impressions-study-drinkware/)).
- **A treat for now.** Ghirardelli premium hot cocoa and 4 Lindt LINDOR milk chocolate truffles, packed inside the mug.
- **A note in your words.** Your message, printed on a textured card that greets each person by first name, in an envelope closed with a gold wax-seal sticker, lying on the lid so it's read before the box opens. In three experiments, people who wrote letters of gratitude "underestimated how positive recipients would feel" ([Kumar & Epley, 2018](https://doi.org/10.1177/0956797618772506)).
- **No ad.** Your logo is on the mug only; the box, the tissue and the card carry none.

You add your logo (or type your website), write one message, add your address list and check the preview of the mug and every card before you pay. We print, pack and ship each box to its own address, at $35 per box, delivered, with no minimum: [a logo mug gift box with Ghirardelli cocoa, Lindt truffles and a personal card](https://personalizedgiftsdelivered.com/custom-logo-mug-gift-box).

## Frequently asked questions

### Do client gifts lead to referrals or repeat business?

Client gifts can affect repeat spending: in a field experiment with 1,950 airline customers, the gifts' effect on spending ran through customers' intention to buy again (Marchand et al., 2017). In business.com's 2022 poll, 46% of gift recipients said vendor gifts made them "more likely to continue working together." We found no study that measures client gifts and referrals.

### Are client gifts worth it for a small business?

For a small business, a client gift is worth it as a modest, personal thank-you more than as a sales tool: recipients' appreciation isn't linked to price (Flynn & Adams, 2009), and no randomized study we found measures a small firm's revenue. Field experiments do show that small, unexpected gifts change what people do.

### Is there research showing that small gifts change people's behavior?

Yes: in a randomized field experiment with about 10,000 charity letters, people donated 17% more often when the letter held a small gift and 75% more often with a large one (Falk, 2007). Randomized field experiments like this are the strongest kind of evidence that a gift caused the change.

### Are corporate gifting statistics reliable?

Many corporate gifting statistics are surveys, and several are run by companies that sell gifts or gifting software, so read them as what recipients say, not proof that gifts raise sales. Check who ran each one, its sample and its year before you quote it.

### How can I tell whether my client gifts worked?

Our suggestion: split one client tier at random, send half the gift now and the other half 90 days later, and compare replies, renewals and referrals between the halves in between. With a small list, treat the result as a hint, not proof.

### Who ships a logo mug gift box with a personal card to each client's address?

Personalized Gifts Delivered ships a $35 logo mug gift box to each client's own address from one list, with no minimum: an 11 oz mug with your logo printed small, Ghirardelli cocoa, 4 Lindt LINDOR milk chocolate truffles and a printed card that greets each person by first name.
