A letter sits on the desk all week. AI made outbound email free, and the inbox absorbed it. The mailbox went the other way: emptier every year, with less to compete against. A good piece gets read and left on the desk, right where your rep's call finds it. It's the one channel your competitors are leaving. - 77% of physical mail gets read or looked at - 120+ a day: emails landing in that same buyer's inbox, the pitches among them mostly deleted unread Industry figures: JICMAIL Q4 2024 · USPS Household Diary Study · email volume research. Averages, not promises, and consumer averages at that. [We went looking for the real B2B evidence.](https://trysincerely.com/does-direct-mail-work) ## The platform The channel, end to end. Sending mail is the easy part. Sincerely runs the rest: the writing, the orchestration, the operations, and the number at the end. Each entry below is one line on the page over a single visual. The detail lives on the linked page. The interactive product demo is further down, under "Inside the product". ### 01 · Writing: [Personalized writing from the account's own signals, every fact sourced](https://trysincerely.com/writing) Shown as a sample letter to Maya, with each claim highlighted and its source named on hover. ### 02 · Formats: [Four formats, one workflow, and no print vendor to contract](https://trysincerely.com/formats) Postcard · Letter · Handwritten · Gift every provider · one interface · one invoice Postcards, letters, and handwritten notes are mailable today. See [/formats](https://trysincerely.com/formats) for what each costs and what is not yet live. ### 03 · Orchestration: [Multi-step campaigns, fired by what your CRM already knows](https://trysincerely.com/campaigns) - signal · Funding round - day 00 · Postcard - day 06 · Letter - delivery · Phone follow-up a sequence for every tier ### 04 · Measurement: [Lift, measured against a holdout, not a send button](https://trysincerely.com/measurement) The worked example is an illustration, not a reported result: a +27% lift, from an 8.9% opportunity rate in the mailed arm against 7.0% in the holdout. Your number comes from your own holdout. ### 05 · Integrations: [Salesforce, HubSpot, or a CSV in. Rep follow-up tasks out.](https://trysincerely.com/integrations) sync in: Salesforce · HubSpot · CSV Out comes a rep task, triggered by delivery confirmation rather than by a send button. ### 06 · Operations: [Operations handled end to end, from the address to the mailbox](https://trysincerely.com/operations) Address resolution (scored) · Mailability (pre-flight) · Approvals (human) · Budgets (enforced) · Fulfillment (one invoice) · Tracking (per-piece) What each one guarantees is on [/operations](https://trysincerely.com/operations). ## Inside the product This is the product. Click around. The interface, live, with sample data. Every tab in the sidebar works: the approval queue, the campaigns, the pieces in motion, and the report at the end. The page embeds an interactive replica of the product interface, driven by sample data, that a reader can click through in the browser. [Start free](https://trysincerely.com/setup) ## After the first deal The channel that opens accounts keeps them, too. Customers stop reading your email long before they stop being customers. The same triggers, pieces, and follow-up tasks run the moments after closed-won, from the onboarding welcome to the renewal letter. [Direct mail for customer relationships](https://trysincerely.com/customer-relationships) ## Agents Your agent does the work. You keep the last word. Sincerely speaks the Model Context Protocol, so the agent you already work with can build the audience, write the pieces, and prepare the campaign here. Anything that prints or spends money stops and shows you a card first, and no setting removes it.
