Sincerely writes each piece for one recipient and measures lift with holdouts. Here is how to pick. Source: https://trysincerely.com/vs/postalytics Postalytics is for marketers who want to automate template-based direct mail from HubSpot or Salesforce at self-serve prices. Sincerely is for B2B teams who want each piece written for one specific recipient, and who want proof of lift from holdout tests rather than delivery reports. These two tools are closer than most pairs on our [vs page](https://trysincerely.com/vs). Both are self-serve. Both sync from HubSpot and Salesforce. Both print postcards and letters with postage included. The split is what a "piece" is. In Postalytics, a piece is a template with merge fields. In Sincerely, a piece is written from scratch for one person, using CRM context and researched account facts, then approved by a human before it prints. ## Quick comparison | Dimension | Postalytics | Sincerely | | --------------- | ---------------------------------------------- | ----------------------------------------------- | | Core model | Templates plus merge fields | Per-recipient written pieces | | Trigger style | Automated flows from CRM events | Campaigns with human approval before print | | Integrations | HubSpot, Salesforce, Zapier, Marketo, and more | Salesforce, HubSpot, CSV, MCP agents | | Formats | Postcards, letters, flyers | Notes, 4x6 and 6x9 postcards, letters | | Measurement | Delivery tracking, QR codes, pURLs | Holdout-measured lift with confidence intervals | | Entry price | Free plan, pay per piece | $199 one-time pilot, 100 pieces included | | Best volume fit | Hundreds to tens of thousands, templated | Tens to thousands, targeted accounts | ## Where Postalytics is the better choice Postalytics has real strengths, and for some jobs it is simply the right tool. - **Automated triggered mail at volume.** Postalytics Flows can fire a postcard from a CRM event with no human in the loop. If you want a mailer to go out automatically when a deal stage changes, that is their core product. Note the tier: as of August 2026, their [pricing page](https://www.postalytics.com/pricing/) lists Flows multi-touch campaign automation only on the $399/month Pro and Agency plans, not on Free or Marketer. Sincerely requires human approval before anything prints, on purpose. - **Lower per-piece cost for templated mail.** As of August 2026, their [pricing page](https://www.postalytics.com/pricing/) lists a 6x9 postcard on Marketing Mail postage at $1.048 on the free plan, $0.928 on Marketer, and $0.838 on Pro and Agency, at volumes under 2,500. First-Class costs more. A template with merge fields costs less to produce than a researched, written piece. If the message is the same for everyone, pay template prices. - **A true free tier.** Postalytics has a $0/month plan where you only pay per piece. You can test a campaign for the cost of the mail itself. - **Broader integration surface.** Zapier, Marketo, ActiveCampaign, Klaviyo, Zoho, and more. Sincerely's native integrations are Salesforce, HubSpot, CSV, and an MCP server, nothing else today. - **Consumer and local-business mail.** Real estate farming, home services, retail promos. High volume, one message, one geography. That is templated mail, and Postalytics is built for it. ## Where Sincerely wins - **The piece itself.** Sincerely writes each piece for one recipient from CRM context and researched account facts. A VP who just raised a Series B gets a letter about that raise, not a template with her first name merged in. For B2B outbound to named accounts, [what the piece says](https://trysincerely.com/writing) is most of the result. - **Proof, not delivery reports.** Postalytics tells you a piece was delivered and whether a QR code was scanned. Sincerely locks an experiment design at launch: primary outcome, window, holdout percentage. Readouts show [lift against account-level holdouts](https://trysincerely.com/holdout-testing) with confidence intervals, and say plainly when a result is not statistically ready. QR scans and CRM matchback are labeled as evidence or inference, honestly. If your CFO asks "did the mail work," a delivery report is not an answer. A holdout readout is. - **Audience building aimed at accounts.** Postalytics is not list-less: as of August 2026 its plans include a mailing list audience builder and the option to buy targeted consumer, B2B, and new-mover lists. The difference is the target. Sincerely finds specific businesses and verified work addresses from a description of your ideal customer, and keeps them in step with your CRM, rather than selling you a list to load. - **Agent access.** Sincerely runs as an [MCP server](https://trysincerely.com/integrations/mcp-agents), so Claude Code, Cursor, or any MCP agent can build audiences and draft campaigns. Anything that spends money still shows a human a confirmation card first. - **Address quality by default.** Every address is resolved, scored, and USPS-verified before print, on every plan, and suppression is immediate and global. ## Pricing reality Postalytics, as of August 2026: Free at $0/month with per-piece billing, Marketer at $199/month, Pro and Agency at $399/month. On the Marketer plan under 2,500 pieces, a 6x9 postcard runs $0.928 and a duplex letter $1.004 on Marketing Mail postage, or $0.981 and $1.251 on First-Class. Volume discounts start above 2,500 pieces. Details are on their [pricing page](https://www.postalytics.com/pricing/). Sincerely: a $199 one-time pilot with 100 pieces included, then Core at $250/month (150 pieces included), Starter at $500/month (350 included), Growth at $1,500/month (1,300 included), and Scale at $3,500/month (3,700 included). Past the included pieces, 6x9 postcards run $1.95 down to $1.20 and letters $2.00 down to $1.25 by tier. Print and postage are included, unused pieces roll over one month, and there is no per-seat pricing. Full detail on [pricing](https://trysincerely.com/pricing). New workspaces start on a free audit plan: connect a CRM, check mailability, and draft pieces before paying anything. The honest read: per piece, Postalytics is cheaper, often by half. You are paying Sincerely for the writing and the measurement, not the postage. ## The decision rule Send the same message to many people on a trigger, and want the lowest cost per piece: use Postalytics. Send a researched, individually written piece to accounts that matter, and need to prove lift with a holdout: use Sincerely. If you are unsure, run the numbers in the [break-even calculator](https://trysincerely.com/tools) with your deal size. Buy Postalytics to automate mail. Buy Sincerely to prove mail works. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow. One invoice. One report.
