Source: https://trysincerely.com/vs/in-house If you mail hundreds of thousands of identical pieces a year, run it in-house: negotiated print rates and full creative control win at that scale. If you send hundreds or a few thousand personalized B2B pieces a quarter, Sincerely wins, because the real cost of in-house mail is not printing. It is the five hidden jobs around it. ## What "in-house" actually means In-house direct mail is not one tool. It is a stack of people and vendors you assemble yourself: - A designer for every format and every revision. - A print vendor or lettershop, with quotes, proofs, and minimum runs. - A spreadsheet of names and addresses, cleaned by hand or not at all. - Someone who writes the copy, once, for everyone. - Someone who tries to measure results afterward, usually by asking sales. Each piece of that stack is fine. The cost is the glue: the emails, the handoffs, the waiting, and the errors between them. ## Quick comparison | Dimension | In-house stack | Sincerely | | ----------------------------- | ---------------------------------------------- | ------------------------------------------------------------------------ | | Per-piece cost at high volume | Wins with negotiated print rates | Fixed [per-piece prices](https://trysincerely.com/pricing), $1.00 to $2.00 | | Cost at 100 to 2,000 pieces | Minimum runs and setup fees hurt | Included pieces from $199 | | Personalization | One message for everyone, or manual mail merge | Every piece written for one recipient from CRM context | | Address hygiene | Manual, or skipped | Resolved, scored, USPS-verified before print | | Creative control | Total: any format, stock, or die cut | Postcards (4x6, 6x9), letters, and handwritten notes | | Measurement | Spreadsheets and anecdotes | Locked [holdout experiments](https://trysincerely.com/holdout-testing) with confidence intervals | | Speed to first send | Weeks: quotes, proofs, list prep | Days: sync CRM, approve drafts, launch | | Vendor management | You, ongoing | None | ## Where in-house is the better choice Be honest about scale. In-house wins in three cases: **Massive, stable volume.** If you mail the same catalog or statement to a large list every month, per-piece cost dominates everything. A direct relationship with a printer, negotiated marketing-mail postage, and a lettershop that knows your file will beat any platform's per-piece price. Sincerely's plans top out at 25,000 pieces a month. Above that, a platform markup buys you nothing you cannot staff. **Full creative control.** Sincerely mails 4x6 and 6x9 postcards, letters, and handwritten notes. If your campaign needs a die-cut mailer, a specialty stock, dimensional packaging, or a booklet, you need a print vendor. No platform format list should stop the right creative idea. **You already have the team.** A working relationship with a designer and a lettershop, a clean list, and a process that ships on time is an asset. Do not replace something that works to chase a tool. If your case is one of these, keep your stack. Use the free [break-even calculator](https://trysincerely.com/tools) to check the math before you change anything. ## Where Sincerely wins Everywhere below that line, the hidden jobs decide it. Here is what in-house actually asks of you, piece by piece: **Address hygiene.** B2B lists rot fast. People change jobs, offices move, suites close. In-house, someone verifies addresses by hand or eats the returned mail. Sincerely resolves, scores, and USPS-verifies every address before anything prints, and can find verified business addresses from a description of your ideal customer. See [address verification explained](https://trysincerely.com/guides/address-verification-explained). **Per-recipient writing.** In-house mail is one message duplicated. That is fine for a catalog and weak for outbound, where the point is relevance. Sincerely writes each piece for one recipient from CRM context and researched account facts. A human approves every piece before it prints. **Approvals.** In-house approval is a PDF proof in an email thread. Miss one reply and the run ships wrong. In Sincerely, drafts sit in a queue, a human signs off, and nothing prints or spends money without that gate. **Vendor management.** Quotes, proofs, minimums, file specs, delivery windows: this is a part-time job that lands on whoever sent the last campaign. Sincerely prints through Lob, and the per-piece price includes print and postage. There is no vendor to manage. **Measurement.** The in-house answer to "did it work" is usually a spreadsheet and a feeling. Sincerely locks an experiment design at launch: primary outcome, window, holdout percentage. Readouts show lift against account-level holdouts with confidence intervals, and say plainly when a result is not statistically ready. See [measurement](https://trysincerely.com/measurement). ## Pricing reality In-house has no price tag, which is exactly the problem. The visible costs are print and postage. The invisible costs are design hours, list cleanup, vendor back-and-forth, and the campaigns that never ship because the process is heavy. At small volumes, minimum print runs and setup fees push the true per-piece cost well above what the quote says. At large stable volumes, the math flips and in-house wins clearly. Sincerely's [pricing](https://trysincerely.com/pricing) is published. Pilot is $199 one-time for 100 pieces, all included. Monthly plans run from Core at $250/month (150 pieces included) to Scale at $3,500/month (3,700 included). Past included pieces, 4x6 postcards run $1.75 down to $1.00 by tier, and letters $2.00 down to $1.25. Print, postage, and address verification are included, and there is no per-seat pricing. You can start free: connect a CRM, audit your list's mailability, and draft pieces without a card. ## The decision rule Count your monthly volume and check your format. Above roughly 25,000 identical pieces a month, or if the creative needs formats beyond postcards, letters, and handwritten notes, build or keep the in-house stack. Below that, sending personalized mail to named accounts, use Sincerely and skip the five hidden jobs entirely. The printer was never the hard part of direct mail. The other five jobs were, and those are the ones worth outsourcing. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow. One invoice. One report.
