Sincerely is built for B2B revenue teams. Here is how to pick between them, with honest pricing for both. Source: https://trysincerely.com/vs/postie Pick by audience, not by feature list. [Postie](https://www.postie.com) sends direct mail to consumers: it builds lookalike audiences from your customer file, retargets website visitors at their home address, and measures ROAS on high-volume drops. Sincerely sends direct mail to business buyers: it pulls accounts from Salesforce or HubSpot, writes each piece for one recipient, and measures lift against a holdout. If your mail goes to households, use Postie. If it goes to named people at target accounts, use Sincerely. ## Quick comparison | Dimension | Postie | Sincerely | | --------------------- | --------------------------------------------------------- | ----------------------------------------------------------- | | Who receives the mail | Consumers at home | Business buyers at work | | Core motion | Acquisition and retargeting at scale | Outbound and ABM to target accounts | | Audience building | Lookalikes, ML segments, site-visitor identity resolution | CRM sync, CSV, or account discovery from an ICP description | | Copy | One creative per segment | Written per recipient from CRM context, human approved | | Measurement | ROAS, CPA, CVR dashboards | Lift vs account-level holdouts, with confidence intervals | | Typical volume | Tens of thousands of pieces and up | Hundreds to low thousands of pieces | | Pricing | Not published; you talk to sales | Public on [pricing](https://trysincerely.com/pricing) | ## Where Postie is the better choice Postie wins whenever the recipient is a consumer and the math runs on volume. - **You sell direct to consumers.** DTC brands, subscription boxes, local services, healthcare consumer plays. Postie's whole model, from lookalikes to identity resolution, assumes a household address. Sincerely resolves business addresses and will be the wrong tool. - **You want prospecting audiences you do not have.** Postie builds lookalike models from your customer file and finds new households that resemble it. Sincerely finds businesses that match an ideal customer profile, which is a different problem. - **You retarget anonymous website traffic.** Postie matches site visitors to home addresses and triggers mail programmatically. Sincerely has no consumer identity graph and does not do this. - **Your volume is large.** If a good month means 50,000 pieces, you need a platform priced and tooled for that scale. Sincerely's [largest published plan](https://trysincerely.com/pricing) includes about 4,000 US postcards a month, and its per-recipient writing model is aimed well below consumer-scale drops. If you are a B2C marketer who landed here, stop reading and go talk to Postie. That is the honest answer. ## Where Sincerely wins Sincerely wins when the recipient is a specific person at a specific company and each piece has to earn a reply. - **Per-recipient copy.** Every piece is written for one person from CRM context and researched account facts, then approved by a human before it prints. A segment-level creative cannot mention the recipient's funding round or the deal that went dark. See [how the writing works](https://trysincerely.com/personalization). - **CRM-native audiences.** Accounts and contacts sync from [Salesforce](https://trysincerely.com/integrations/salesforce) or [HubSpot](https://trysincerely.com/integrations/hubspot), or import by CSV. Suppression is immediate and global. Business addresses are resolved and checked for mailability before anything prints. - **Honest measurement at B2B volume.** ROAS dashboards need consumer-scale conversion counts to mean anything. At 500 pieces, you need an experiment. Sincerely locks a design at launch, holds out accounts, and reports lift with confidence intervals. When a result is not statistically ready, the readout says so. Read [how measurement works](https://trysincerely.com/measurement). - **The page behind the piece.** Postie's mail points at your site. 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. At 500 pieces nobody can staff a page per contact, and you do not have to. See [landing pages](https://trysincerely.com/landing-pages). - **Agent access.** Sincerely runs as an MCP server, so an agent like Claude Code can build audiences and prepare campaigns. A human confirms anything that prints or spends money, and no setting removes that gate. Sincerely publishes the package and format terms active for the current deployment on the [pricing page](https://trysincerely.com/pricing). Formats live today are standard 4x6 and 6x9 postcards, letters, and 46 curated gifts, 28 of them shipping to Canada. Handwritten 4x6 postcards and letters are genuinely written by hand and photographed before they mail. Current format charges are on [pricing](https://trysincerely.com/pricing). ## Pricing reality Postie does not publish pricing. As of August 2026, [postie.com](https://www.postie.com) has no pricing page and no self-service tiers, and the site sends you to a contact form for a quote. Quotes depend on volume, so budget for a contract, not a card swipe. Sincerely publishes the package and format terms active for the current deployment on the [pricing page](https://trysincerely.com/pricing). ## The decision rule Ask one question: whose mailbox does this land in? A household mailbox at scale means Postie, with lookalikes, retargeting, and ROAS math built for consumers. A named buyer's desk at a target account means Sincerely, with per-recipient copy, CRM sync, and holdout-measured lift. Volume confirms the call: tens of thousands of identical pieces is Postie territory, hundreds of individually written ones is Sincerely's. Postie mails audiences. Sincerely mails people you can name. ## Related questions - [Postie vs Poplar for programmatic direct mail](https://trysincerely.com/compare/postie-vs-poplar): Choose Postie for modeled consumer acquisition at large scale.
