Six tests to run in a pilot, and which platforms fit which program. Source: https://trysincerely.com/guides/enterprise-direct-mail-platform A direct mail platform is ready for enterprise scale when it can prove what happened to every piece and stop the pieces that should not go. That means duplicate requests that cannot print twice, spending limits enforced before anything prints, suppression that reaches every team, a record nobody can edit, and a security review that clears. Template libraries and format catalogs are less important than vendor demos make them seem. Most large programs fail because of weak controls, not weak creative, so test controls first. ## Why enterprise mail fails differently A team of three mailing 200 accounts catches its own mistakes. Someone notices the CSV has the same VP twice, or that a customer who asked to stop is still on the list. At enterprise scale, five teams mail the same accounts from different tools, sequences fire from CRM rules nobody owns anymore, and a retry after a timeout quietly prints a second batch of 8,000 letters. Paper makes those failures expensive and public. An email sent twice is an annoyance. A gift sent twice to a government buyer is a compliance incident, and a letter sent after an opt-out is a complaint with your logo on it. Those are the failures to test for. ## Six tests to run in a pilot Ask for a sandbox or a small paid pilot, and run these yourself rather than accepting a slide. 1. **Send the same request twice.** Submit an identical send, or let your integration retry after a timeout. One piece should exist afterwards. Ask how the platform keys a piece, and whether that key reaches the printer, because a platform that deduplicates internally can still send a second job if its printer call is retried. 2. **Suppress someone mid-campaign.** Add a contact to the suppression list after their piece is queued but before it prints. The queued piece should cancel, and every other team's campaign should skip that person too. A suppression list scoped to one campaign or one user is not a suppression list. 3. **Exceed a budget.** Set a campaign cap below what the audience would cost. The platform should stop before the piece that would cross the cap prints, not send an invoice afterwards. 4. **Let a junior user try something expensive.** A rep should be able to send what their role allows and nothing more. Check whether a large launch needs a second person, and whether someone can approve their own request. 5. **Ask for the record.** Pick one piece and ask who approved it, which design version printed, what address was used, and when the printer accepted it. Then ask whether anyone, including an admin, can edit that record. 6. **Break a printer.** Ask what happens when the print partner is down or rejects a job. Some platforms route around an outage across a print network. Others queue and wait. Both can be fine. Find out which one you are buying before the first outage. ## The security review Security teams ask for the same documents everywhere: a SOC 2 Type 2 report, SAML single sign-on, a data processing agreement, and an answer about where customer data lives and who can reach it. Healthcare adds a HIPAA business associate agreement. Collect these before the pilot. A platform that cannot clear your review will not get past procurement, however well the pilot goes. Ask how one customer's data is kept from another's. "Separate accounts" is an answer about the login screen. Row-level security in the database, or separate databases, is an answer about the data. ## Decide what scale means for your program "Enterprise scale" means different things for different programs. Write down which of these you need before you compare vendors: - **Volume.** A statement run of 50,000 letters a month and an ABM program of 400 researched letters a month are both enterprise programs. They need different tools. - **Countries.** A platform built for the United States and Canada will not work for a team that mails to Germany, Japan, or Brazil. - **Formats.** Postcards and letters are standard. Branded kits, dimensional mailers, and warehoused swag need a fulfillment operation behind the software. - **Integrations.** Decide where triggers live: the CRM, a marketing automation platform such as Marketo, a customer data platform, or your own code. - **Proof of effect.** Decide whether finance will accept influenced pipeline or wants a randomized holdout. That choice changes which platforms qualify. ## Which platforms fit which shape | Shape of program | Better fit | | -------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | High-volume mail generated by your own software | [Lob](https://www.lob.com/pricing), which lists HIPAA-compliant mailing support on its Enterprise plan, or [PostGrid](https://www.postgrid.com/pricing-print-mail/), which lists single sign-on and Certified Mail on Enterprise | | Branded kits and complex print formats triggered from a marketing cloud | [PFL](https://trysincerely.com/vs/pfl) | | Gifts and swag across many countries | [Reachdesk](https://trysincerely.com/vs/reachdesk), with warehouses for delivery to 180+ countries, or [Sendoso](https://trysincerely.com/vs/sendoso) | | Consumer acquisition mail at high volume | [Postie](https://trysincerely.com/vs/postie) | | Researched letters and handwritten notes to named B2B accounts, measured with holdouts | Sincerely, within the limits below | Sincerely is a paying customer of Lob and PostGrid, so read this comparison with that in mind. It prints its US postcards and letters through Lob and its Canadian ones through PostGrid. ## How Sincerely does on the six tests Sincerely does well on the control tests and falls short on parts of the security review. Each piece is unique on the account's enrollment and the campaign step, and the same key goes to Lob or PostGrid as an idempotency key, so a retry cannot print a second piece. Suppression is global across the workspace and cancels queued pieces that a printer has not accepted. A default cap of three pieces per contact per 30 days applies across every campaign, and the [two-teams guide](https://trysincerely.com/guides/stop-two-teams-mailing-the-same-account) explains which campaign wins when they collide. Campaigns stop before a piece would exceed their credit envelope. Workspaces have owner, admin, approver, and member roles. Owners and admins can block a member from sending, set a monthly spending limit per member, and grant campaign management to someone who is not an admin. A launch whose estimated gift cost is over $1,000 needs approval, as does a launch that would take someone past their monthly limit, and nobody can approve their own launch request. A campaign that runs on CRM or API events needs an approval before it activates. The audit log is append-only at the database level, and it can be filtered and downloaded as CSV from Settings. Tenancy is enforced with row-level security in Postgres. Some enterprise buyers will hit these gaps. Sincerely does not offer SAML single sign-on or publish a SOC 2 report today. It mails to the United States and Canada only. Each route uses one fulfillment path, so an outage delays pieces rather than moving them elsewhere. Only standard US pieces sent through Lob return automatic postal delivery events. Gifts carry carrier tracking and can receive delivery confirmation from the fulfillment team; handwritten mail has no delivery confirmation and Canadian printed mail reports an estimate. Its workspace REST API has three endpoints, limited to 60 requests a minute per key, and it sends no webhooks to customer systems. Its published plan caps, prepaid balances, and handwriting capacity determine the volume it can fulfill. Review those limits against the program's size before choosing a plan. If your security review requires SSO or a SOC 2 report, choose a different platform. If your program is a few hundred named accounts a month and finance wants a holdout, the [best direct mail software guide](https://trysincerely.com/guides/best-direct-mail-software) explains where Sincerely fits among the other nine. ## Related questions - [The best direct mail software in 2026, by use case](https://trysincerely.com/guides/best-direct-mail-software): Ten direct mail platforms compared by use case, with each one's real strength, real shortcoming, and pricing model.
