A letter sits on the desk all week. Every vendor is running sequences into your target accounts' inboxes, and the inbox absorbs them without noticing. A good piece of mail gets opened, read, and left on the desk, which is exactly where your rep's call finds it. Physical isn't nostalgic. It's the one channel your competitors aren't in. - 77% of 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. ## 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. ### 01 · Writing: [Personalized writing at scale](https://trysincerely.com/writing) You make the template. AI personalizes every outgoing piece from the account's signals: the round they raised, the roles they opened, the product they shipped. Every fact carries its source. ### 02 · Formats: [Two formats live, one workflow](https://trysincerely.com/formats) Postcards and letters at published per-piece prices. Handwritten notes and gifts are built and not yet mailable. You contract with no print vendor. Postcard · Letter · Handwritten, soon · Gift, soon every provider · one interface · one invoice ### 03 · Orchestration: [Multi-step campaigns, fired by signals](https://trysincerely.com/campaigns) Sequences trigger on what your CRM already knows: a funding round, a renewal window, a deal gone quiet. They run to a cadence, and eight campaign types cover the funnel. - signal · Funding round - day 00 · Letter - day 06 · Postcard - delivery · Rep task a sequence for every tier ### 04 · Measurement: [Measured against a holdout](https://trysincerely.com/measurement) QR scans catch direct response, matchback ties meetings to mailed accounts, and account-level holdouts measure lift. Evidence and inference, labeled. The page illustrates this with a worked example, 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: [Plugs into your revenue stack](https://trysincerely.com/integrations) Salesforce, HubSpot, a CSV, or a description of your ideal customer in. Rep follow-up tasks come out, timed to delivery confirmation, not to a send button. sync in: Salesforce · HubSpot · CSV ### 06 · Operations: [Operations handled end to end](https://trysincerely.com/operations) - **Address resolution** (scored): A waterfall across data sources and your CRM. Every address carries a confidence score and provenance. - **Mailability** (pre-flight): Verification before postage. Low confidence goes to a review queue, never to the mailbox. - **Approvals** (human): Nothing prints without a human sign-off, and every edit is versioned. - **Budgets** (enforced): Spend limits set once, enforced on every campaign before a piece is queued. - **Fulfillment** (one invoice): Print, postage, and providers managed behind one invoice, with the markup disclosed. - **Tracking** (per-piece): Every piece tracked to the mailbox. Delivery timing drives the follow-up. ## 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.
