Sincerely is measured B2B direct mail. Here is how to pick between gifts with influenced pipeline and mail with holdout-proven lift. 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 mail campaigns, in postcards, letters, or handwritten notes, where every piece is written for one recipient and results are measured against a holdout. 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, prints through Lob, mails handwritten notes through Handwrytten, and reports lift with confidence intervals. ## Quick comparison | Dimension | Sendoso | Sincerely | | ------------- | --------------------------------------------------- | ---------------------------------------------------- | | Core product | Gifts, e-gifts, swag, event kits | Handwritten notes, postcards, and letters | | Physical mail | One channel among many | The whole product | | 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, from $199 one-time | | Buyer | Enterprise marketing and sales ops | B2B teams running outbound and ABM | | Logistics | Global warehousing, inventory, address confirmation | USPS-verified addresses, 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 marketplace, international fulfillment, and address confirmation flows built for gifting. Sincerely cannot mail gifts today. Gifts exist in the product but have no live fulfillment, so a gift campaign will not launch. - **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 kills two problems Sendoso does not try to solve: generic mail and unprovable results. **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 postcard, letter, or handwritten note from CRM context and researched account facts, and a human approves everything before it prints. A letter that references the recipient's actual situation outperforms a template with a first-name merge field. Read more about [how the writing works](https://trysincerely.com/writing). **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.** Every address is resolved, scored, and USPS-verified before printing. 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 everything on the [pricing page](https://trysincerely.com/pricing). A Pilot is $199 one-time for 100 pieces, all included. Core is $250/month with 150 pieces included. Starter is $500/month with 350 included. Growth is $1,500/month with 1,300 included. Per-piece prices include print and postage: a 4x6 postcard runs $1.75 on Core down to $1.00 on Scale. Handwritten notes are priced per card on your plan, with the rate falling at every plan step and the exact number shown in the app. Address verification is included on every plan, unused pieces roll over up to one extra month, and there is no per-seat pricing. The practical difference: with Sendoso you cannot price the program until a quote arrives. Sincerely lets you test the channel for $199 and prove lift before you scale. ## 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 postcard, a letter, or a handwritten note that has to earn a reply, and you need proof it moved pipeline, use Sincerely. Some teams run both: Sendoso for late-stage and customer gifting, Sincerely for measured outbound mail.
