Sincerely is measured B2B direct mail. How to pick between influenced pipeline and account-level holdouts. Source: https://trysincerely.com/vs/sendoso Pick Sendoso if you want to send gifts, swag, and e-gift cards at enterprise scale. Pick Sincerely if you want to run standard postcard or letter campaigns where every piece is written for one recipient and results are measured against a holdout. Handwritten 4x6 postcards and letters are genuinely written by hand. These are different products that happen to share a mailbox. Sendoso is a sending platform: a marketplace of gifts, warehousing for your swag, and Amazon-style logistics for getting a bottle of wine to a VP. Sincerely is a direct mail platform: it builds the audience, writes each piece from CRM context, routes each format through its production layer, and reports lift with confidence intervals. ## Quick comparison | Dimension | Sendoso | Sincerely | | ------------- | --------------------------------------------------- | ---------------------------------------------------------- | | Core product | Gifts, e-gifts, swag, event kits | Personalized mail and curated physical gifts | | Physical mail | One channel among many | Postcards, letters, handwritten mail, and gift notes | | Writing | Templates, sender picks a message | Written per recipient from CRM and account research | | Measurement | Influenced pipeline, touch attribution | Lift vs account-level holdouts, confidence intervals | | Pricing | Not published; talk to sales | Published on [pricing](https://trysincerely.com/pricing) | | Buyer | Enterprise marketing and sales ops | B2B teams running outbound and ABM | | Logistics | Global warehousing, inventory, address confirmation | US and Canadian address checks, print and postage included | ## Where Sendoso is the better choice Be honest about what Sendoso does well. If your problem is one of these, buy Sendoso, not Sincerely. - **Gifts and e-gift cards.** Sendoso has a broad marketplace, e-gifts, international fulfillment, and recipient address confirmation. Sincerely has 46 curated physical and branded gifts in the United States and Canada. Sendoso wins on breadth and global scale; Sincerely keeps a narrow gift in the same approval and measurement workflow as mail. - **Swag logistics.** If you have branded merchandise sitting in a warehouse and need it kitted and shipped worldwide, that is Sendoso's core business. - **Event amplification.** Pre-event boxes, booth giveaways, and post-event thank-you gifts are a Sendoso strength. They handle the inventory and the shipping mess. - **Enterprise sending programs.** Budgets per team, approval chains across regions, integrations into large sales-engagement stacks. Sendoso is built for a global org with a gifting line item. If gifting is a small part of what you need and mail is the main event, keep reading. ## Where Sincerely wins Sincerely combines researched mail writing with account-level experiments. A holdout estimates the effect of a campaign; it does not guarantee a positive or conclusive result. **Every piece is written for its recipient.** Sendoso sends are a chosen item plus a note the sender types or picks from a template. Sincerely drafts each live standard postcard or letter from CRM context and researched account facts, and a human approves everything before it prints. This lets a draft explain why the message is relevant to that account. Whether it earns more replies than a template is something to test. Read more about [how the writing works](https://trysincerely.com/personalization). **The piece has a page behind it.** A gift arrives with a note and a claim step. Each printed postcard and letter can carry a QR code and short link that opens a page Sincerely hosts for the intended recipient, or redirects to your site once Sincerely records the visit. See [landing pages](https://trysincerely.com/landing-pages). **One campaign, one budget, one holdout.** Printed postcards and letters and the 46-gift catalog, 28 gifts of which ship to Canada, share one audience, one suppression list, one budget, and one holdout. Handwritten pieces are genuinely written by hand and photographed before they mail. **Measurement is an experiment, not a report.** This is the sharpest difference. Sendoso reports influenced pipeline: deals that a send touched. Influenced pipeline cannot tell you whether the deal would have closed anyway. Sincerely locks an experiment design at launch: primary outcome, window, and holdout percentage. Readouts show lift against account-level holdouts with confidence intervals, and say plainly when a result is not statistically ready. QR scans and CRM matchback are labeled as evidence or inference, honestly. The [holdout testing guide](https://trysincerely.com/holdout-testing) explains the method. **You can start without a sales call.** New workspaces begin on a free audit plan. Connect Salesforce or HubSpot, audit your mailability, and draft pieces before you pay anything. Nothing mails until you choose a plan. **Address quality is built in.** Addresses are resolved and checked for mailability before printing. US addresses use USPS delivery-point checks; Canadian addresses use Canada Post verification. Neither establishes that the intended person works there. Suppression is immediate and global. ## Pricing reality **Sendoso** does not publish prices. As of August 2026, their [pricing page](https://sendoso.com/pricing) lists Starter, Core, Advanced, and Enterprise tiers, and every one routes to a sales conversation. The page names no platform fee, and no gift or shipping rates, so ask for both lines in the sales call. Budget a procurement cycle, not a credit card. Sincerely publishes the package and format terms active for the current deployment on the [pricing page](https://trysincerely.com/pricing). The practical difference: with Sendoso you cannot price the program until a quote arrives. Sincerely offers a $199 pilot capped at 100 pieces to test the workflow and collect response evidence. That small pilot does not establish incremental lift on its own. Use the [holdout size calculator](https://trysincerely.com/tools/holdout-size) before planning a causal test, and read the [small-audience guide](https://trysincerely.com/guides/direct-mail-small-audiences) if the required sample is out of reach. ## The decision rule Ask one question: is the thing in the envelope a gift or a message? If it is a gift, a kit, or a gift card, and you need enterprise logistics behind it, buy Sendoso. If it is a standard postcard or letter that has to earn a reply, and you need evidence about whether it moved pipeline, use Sincerely. Some teams run both: Sendoso for late-stage and customer gifting, Sincerely for measured outbound mail. See the broader [gifting platform comparison](https://trysincerely.com/vs-gifting-platforms) if you are weighing the whole category. Delivery tracking shows where a shipment went. Sincerely estimates incremental outcomes with account-level holdouts and uncertainty intervals when the sample supports a readout. Those are different questions, and neither guarantees that mail created pipeline. ## Related questions - [Sendoso vs Alyce after the acquisition](https://trysincerely.com/compare/sendoso-vs-alyce): Alyce is now part of Sendoso.
