Three of them publicly recommend holdout testing. None of them run the holdout for you. What we checked, what we found, and where they are the better choice. Source: https://trysincerely.com/vs-gifting-platforms ## They will all tell you to run a holdout. None of them will run it for you. Sendoso, Reachdesk, Postal and PFL are real products with real strengths, and if what you need is gifting at scale, several of them are better at it than we are. This page is about one thing only: what happens when someone asks whether the spend actually caused anything. Vendor pages reviewed 25 July 2026. These are live sites and they change; if something here is out of date, write to us and we will correct it. ## First, fairly What each one is genuinely good at. A comparison that only lists gaps is a sales document, not a comparison. These are strong products and they are not trying to be what we are. | Vendor | What they are genuinely good at | Strength | | --------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ------------ | | Sendoso | The widest product range in the category, gifting, swag, eGifts, virtual experiences, direct mail, on company-owned fulfilment infrastructure, with the largest verified integration ecosystem: Salesforce, HubSpot, Outreach, Salesloft, Marketo, 6sense and Gong. | breadth | | Reachdesk | The widest international claim of anyone here, at 180+ countries, and the only vendor in this group that publishes a price floor rather than routing everything to sales. | global reach | | Postal | Consistently praised for usability, with a strong People Ops and employee-engagement lean that the others treat as secondary. | ease of use | | PFL | Deep print production heritage and mature enterprise integrations across Salesforce, Marketo, Eloqua, Iterable and Braze. Reviewers actively praise its attribution reporting. | print depth | ## What their measurement pages say Every one of these is a credit-assignment claim. Quoted from each vendor's own site. Read them closely and the same word keeps appearing: _influenced_. Influenced pipeline counts deals that moved after a send. It does not distinguish the ones that would have moved anyway, which is the entire question a CFO is asking. | Vendor | What their page says | Source | | --------- | ---------------------------------------------------------------------------------------------------------------------------------------- | ----------------------------------------------------------- | | Sendoso | "$4K in influenced pipeline for every dollar spent" | [homepage](https://www.sendoso.com/) | | Reachdesk | "attributed ROI and campaign influence data" | [reporting page](https://www.reachdesk.com/reporting) | | Postal | "View pipeline, opps, and closed/won revenue influenced by Postal" | [reporting page](https://www.postal.com/platform/reporting) | | PFL | "PFL logs each mail send and delivery as an activity, giving attribution tools the data they need to assign credit in your chosen model" | [FAQ](https://www.pfl.com/) | PFL's is the most candid of the four, and worth reading twice: it describes itself as the thing that feeds _your_ attribution tool, in whichever model you have chosen. That is an honest description of what every product on this page does. ## The gap Three of them publish advice on running holdouts. This is the part we found genuinely surprising. The category understands incrementality perfectly well. It writes about it, accurately, in public. It just does not ship it. ### Sendoso > "A holdout group is a randomly selected portion of the target list that does not receive a gift, used as a control to isolate the effect of gifting from other variables." From their own blog, May 2026. The same page separately names Sendoso's measurement features. Holdout creation is not among them; the advice sits in the advisory section. ### Postalytics > "Build true holdout groups: a segment that receives no mail, so you can measure incremental lift." April 2026. Their split-testing documentation covers creative against creative. A holdout is not documented as a product feature. ### PFL > "you're using matchback for directional data, holdout for incrementality, and multitouch to understand the multichannel context." Their own VP of Customer Success, September 2025. Exactly right, and exactly the thing the product leaves to you. ## What that costs you Seven months. Weekly spreadsheet pulls. The clearest description of this gap is not ours. It is in PFL's own featured customer story, describing how PODS measured their program. A team that wanted a real answer built the experiment by hand, ran it for the better part of a year, and moved the data every week themselves. That is what rigour costs when the platform does not provide it, and note who did the work. The case study ends by calling automation a future goal. ### From PFL's PODS case study "The team designed a true control-versus-test A/B experiment, splitting a carefully curated audience fifty-fifty and running the test for a long period of time to ensure statistical significance. They ran that test for about seven months." | Item | Value | | ----------------- | --------------- | | experiment design | by the customer | | duration | ~7 months | | data movement | weekly, manual | | automation | "a future goal" | Quoted from [pfl.com](https://www.pfl.com/). Reviewed 25 July 2026. ## What we actually checked The evidence behind everything above. We sell measurement, so it would be strange to make competitive claims without showing our method. Here is exactly what was examined, and where our evidence is weaker than we would like. | Vendor | What was examined | Depth | | --------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ---------- | | PFL | Every page on the public site was retrieved and searched. Across 438 pages: one mention of "holdout", one of "incrementality", two of "control group", and none of "incremental lift", "randomized", or "test and control". | exhaustive | | Reachdesk | Their reporting page and FAQ were retrieved in full. Neither mentions holdout groups, control groups, incrementality, or incremental lift. Those are the two pages a buyer would consult on measurement. | page-level | | Sendoso | Homepage, pricing, integrations and global sending retrieved; a search of their support knowledge base surfaced no article documenting a holdout or control-group feature. | page-level | | Postal | Reporting page retrieved. No holdout, control-group or incrementality language. Single page checked. | page-level | The honest limitation: only PFL was crawled exhaustively. For the other three we can say their measurement pages make no mention of holdouts, not that the word appears nowhere on their sites. If any of these vendors ships holdout testing and we have missed it, tell us and this page changes the same week. ## The category Three of the five are no longer independent. Worth knowing if you are signing a multi-year agreement, and worth stating without spin: every acquired product still operates under its own brand, and two of the three deals had undisclosed terms. | Product | What happened | Date | | ------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------- | | Alyce | Acquired by Sendoso in February 2024 and operating as "Alyce by Sendoso". As of 25 July 2026, alyce.com does not resolve to a live website, though the domain remains registered. | Feb 2024 | | Postal | Acquired by Sendoso, announced May 2025, terms undisclosed. Their own site carries the banner "Postal is now part of the Sendoso family", and the product continues to operate separately. | May 2025 | | PFL | Acquired in July 2025 by The Vomela Companies, a private-equity-backed print group roughly ten times its size. The platform continues; the site's navigation shifted from "Platform" to "Direct Mail Products" shortly afterwards. | Jul 2025 | ## The honest part When you should pick one of them. We are narrower than these platforms on purpose. If you recognise yourself here, they are the better buy and we would rather you knew now. | If this is you | Why they are the better buy | | ------------------------------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | You want gifting first | Swag stores, virtual experiences, employee gifting, recipient-choice flows, physical inventory in warehouses. Sendoso and Reachdesk built exactly that and we have not. | | You need broad international coverage today | Reachdesk claims 180+ countries. We print domestically in the United States and Canada, and have the UK and EU on the roadmap rather than in production. | | Nobody is going to ask what it caused | If mail and gifts are a relationship gesture rather than a funded channel with a number attached, the measurement layer is the most expensive part of us and you would be paying for it unused. | | People Ops is the main use case | Onboarding kits, work anniversaries, employee recognition. Postal in particular is strong here and we are not built for it at all. | What is left is the case we are built for: a revenue team running mail as a funded channel that has to report a number someone will interrogate. The [holdout testing guide](https://trysincerely.com/holdout-testing) covers how that number is produced, and the [measurement page](https://trysincerely.com/measurement) shows what the report looks like. --- Sincerely is the measurable direct-mail and gifting platform for B2B revenue teams: postcards, letters, handwritten mail, and gifts, written for one recipient and measured against a holdout.
