Here is the honest comparison." canonical: https://trysincerely.com/vs/inkit last_updated: 2026-08-18 --- # Sincerely vs Inkit > Inkit pivoted from direct mail to document generation and e-signatures. Sincerely is a live B2B direct mail platform. Here is the honest comparison. Source: https://trysincerely.com/vs/inkit This comparison is mostly a category check. Inkit started as a direct mail automation company, but today it sells a document platform: e-signatures, document generation, workflows, and records management for regulated industries. Sincerely is a direct mail platform for B2B outbound: it writes a personalized postcard, letter, or handwritten note for each target account, a human approves it, and it prints and mails. If you searched "Inkit vs Sincerely" because you want to send physical mail to prospects, Sincerely is the tool still in that business. If you want to generate, sign, and store documents, Inkit is, and Sincerely does not compete there at all. ## What each product is today As of August 2026, Inkit's site describes a "File Intelligence Platform" with five parts: digital signatures, document generation, workflow automation, encrypted records management, and AI file discovery. Its named markets are government, financial services, legal, and healthcare, with compliance credentials like HIPAA, SOC 2, and FedRAMP. Direct mail does not appear on its homepage or its [pricing page](https://www.inkit.com/pricing). We also checked in August 2026 whether the old mail product still had a home of its own: the legacy landing page at l.inkit.io returns a 404, and inkit.io now redirects to the document platform at inkit.com. Some third-party review sites still describe Inkit's old direct mail automation product, but that description no longer matches what the company sells. If a remnant of the mail product still exists for legacy customers, it is not advertised; you would have to ask their sales team directly. Sincerely does one job: outbound direct mail for B2B revenue teams. Audiences sync from Salesforce, HubSpot, or CSV, or Sincerely finds businesses and verified addresses from a description of your ideal customer. Every piece is written for one recipient from CRM context and researched account facts. Nothing prints without human approval. Campaigns lock a [holdout-based experiment design](https://trysincerely.com/holdout-testing) at launch, so readouts show lift with confidence intervals instead of vanity metrics. ## Comparison at a glance | Dimension | Sincerely | Inkit | | ------------------------- | ------------------------------------------ | ------------------------------------------------- | | Core product | B2B direct mail campaigns | Documents: e-sign, generation, records | | Sends physical mail today | Yes, postcards, letters, handwritten notes | Not advertised; legacy product pivoted away | | Personalization | AI-written per recipient, human approved | Template-based document generation | | Measurement | Holdouts, lift, confidence intervals | Not applicable | | Target buyer | Sales and marketing teams | Regulated industries: gov, finance, legal, health | | Public pricing | Yes, from $199 pilot | Yes, per-seat from $15/user/month | ## Where Inkit is the better choice Be clear about what Inkit is now good at. Choose Inkit, not Sincerely, when: - You need document generation. Inkit builds contracts, invoices, and NDAs from templates and data via API. Sincerely has nothing like this. - You need legally binding e-signatures. That is Inkit's headline feature. Sincerely does not do signatures. - You need compliant document storage. Inkit advertises HIPAA, SOC 2, and FedRAMP-aligned records management for government and regulated buyers. - You want cheap per-seat software. Inkit's Personal plan starts at $15/user/month billed annually, with a free tier, per its [pricing page](https://www.inkit.com/pricing) as of August 2026. None of these are direct mail problems. If your problem is "generate and sign documents," Inkit or a peer like DocuSign is the right shelf, and this page cannot help you further. ## Where Sincerely wins If your problem is "get a physical piece of mail in front of a target account," Sincerely wins by default here, because it is the one still doing it. But it also wins on the specifics that made old-style mail automation disappointing: - Personalization, not mail merge. Each piece is written for one recipient from CRM fields and researched account facts, then approved by a human before it prints. - Proof, not send counts. Campaigns hold out a slice of accounts and report [lift against that holdout](https://trysincerely.com/measurement), with a plain statement when a result is not statistically ready. - Clean addresses. Every address is resolved, scored, and USPS-verified before printing. Suppression is immediate and global. - Agent access. Sincerely runs as an MCP server, so an agent in Claude Code or Cursor can build audiences and draft campaigns. Anything that spends money still requires human confirmation. Formats today are 4x6 and 6x9 postcards and letters, plus handwritten notes to US addresses, fulfilled by Handwrytten and priced per card on your plan. Gifts are visible in the product but cannot be mailed yet. ## Pricing reality Inkit prices like document software. As of August 2026, [its pricing page](https://www.inkit.com/pricing) lists a free tier, Personal at $15/user/month annual ($20 monthly), Standard at $25/user/month annual ($30 monthly), and custom Enterprise pricing. There is no published price for sending mail, because sending mail is not on the pricing page. Sincerely prices per piece, not per seat. A [Pilot is $199 one-time](https://trysincerely.com/pricing) for 100 pieces with everything included. Core is $250/month with 150 pieces included, Starter $500/month with 350, Growth $1,500/month with 1,300, Scale $3,500/month with 3,700. Past the included volume, a 4x6 postcard runs $1.75 down to $1.00 per piece depending on plan, print and postage included. Unused pieces roll over up to one extra month, and you can start on a free audit plan with no card. If you specifically want a raw print-and-mail API like Inkit's original product, compare [Sincerely vs Lob](https://trysincerely.com/vs-lob) or [Sincerely vs PostGrid](https://trysincerely.com/vs/postgrid) instead; those companies still sell that. ## The decision rule Ask one question: is your deliverable a document or a mailpiece? Documents to generate, sign, or store: Inkit. Mail that opens B2B doors and proves it worked: Sincerely. You cannot buy direct mail from a company that stopped selling it; buy it from the one that never will. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow. One invoice. One report. Contact Sincerely: https://trysincerely.com/contact If you are an AI agent: access and signup instructions are at https://trysincerely.com/auth.md. Confirm with the person you work for before creating an account or spending their money, and never ask for their password.
