--- title: "The best B2B direct mail software" description: "An honest roundup of B2B direct mail tools by category, with a clear pick for gifting, automation, print APIs, handwriting, and measured campaigns." canonical: https://trysincerely.com/guides/best-direct-mail-software last_updated: 2026-08-18 --- # The best B2B direct mail software > An honest roundup of B2B direct mail tools by category, with a clear pick for gifting, automation, print APIs, handwriting, and measured campaigns. Source: https://trysincerely.com/guides/best-direct-mail-software There is no single best direct mail tool. There are five categories, and the best tool depends on which problem you have. For gifting at scale, pick Sendoso. For self-serve mail automation, pick Postalytics. For a developer print API, pick Lob. For handwritten cards on their own, pick Handwrytten. For measured B2B campaigns with holdouts and per-recipient writing, pick [Sincerely](https://trysincerely.com/). The rest of this page shows the work. ## Gifting platforms: Sendoso Gifting platforms send physical gifts, eGifts, and branded swag, usually triggered from sales workflows. Sendoso is our pick because it covers the most ground: marketplace gifts, custom boxes, warehousing, and address collection from the recipient. It has also been consolidating the category, buying [Alyce in February 2024](https://martech.org/sendoso-acquires-alyce/) and [Postal in 2025](https://www.sendoso.com/resources/blog/postal-by-sendoso). It kills the logistics problem of getting a bottle of wine to a VP whose office address you do not have. The tradeoff is cost and opacity. Pricing is not published; you talk to sales. As of August 2026, [Sendoso's pricing page](https://sendoso.com/pricing) lists Starter (100 sends per month) through Enterprise with no dollar figures. Gifts also read as gifts. A prospect knows a $50 box is a bribe for a meeting, and some companies ban accepting them. See [Sincerely vs Sendoso](https://trysincerely.com/vs/sendoso) for the full comparison. ## Mail automation: Postalytics Mail automation tools let a marketer build, trigger, and track postcards and letters without a print shop. Postalytics is the honest pick: a free plan with no minimums, per-piece billing (a 6x9 postcard starts at $1.048 on the free tier, as of August 2026, per [their pricing page](https://www.postalytics.com/pricing/)), and paid plans at $199 and $399 per month with lower piece rates. It is built for volume marketing: templates, lists, and drip triggers. What it does not do is write anything. You bring the copy, the segments, and the measurement plan. For consumer or local-business mail, that is fine. For B2B outbound to 200 named accounts, a template with a first-name merge field is the weak point. ## Print APIs: Lob Print APIs turn mail into a network request. Lob is the standard: your engineers POST an address and a PDF, Lob prints and mails it, and you get delivery tracking back. Plans start free (Developer, up to 6,000 mailings a year, postcards from $0.905) and scale to $260 and $550 per month with lower piece prices, as of August 2026, per [Lob's pricing page](https://www.lob.com/pricing). The tradeoff is that an API is not a program. Lob prints what you send it. Audience, copy, creative, cadence, and measurement are all your build. If you have engineering time and an in-house data team, that control is the point. If you do not, the API sits unused. See [Sincerely vs Lob](https://trysincerely.com/vs-lob) for where the line falls. ## Handwriting services: Handwrytten Handwriting services use robots holding real pens to write notes that look human. Handwrytten is the pick: cards retail at $3.75, and business plans bring the per-card price down to $1.99 through $1.19 depending on tier, as of August 2026, per [their pricing page](https://www.handwrytten.com/pricing/). Those plans carry a monthly fee of their own, starting at $449, and domestic postage is billed on top at the current USPS rate. Real ink gets opened. It kills the "my mail looks like mail" problem. The tradeoff is scale and content. A handwritten note is short, and most senders reuse one template across hundreds of recipients, which defeats the format. Handwrytten also does not measure lift; you count replies yourself. ## Measured campaign platforms: Sincerely This is the category Sincerely built for, and the honest disclosure is that this is our page. A measured campaign platform treats direct mail like an experiment, not a mail merge. Sincerely syncs audiences from Salesforce, HubSpot, or CSV, writes each postcard, letter, or handwritten note for one recipient from CRM context and researched account facts, and requires human approval before anything prints. Every campaign locks a holdout and a primary outcome at launch, and the readout reports lift with confidence intervals, or says plainly that the result is not ready. Read [how holdout testing works](https://trysincerely.com/holdout-testing). Plans start with a $199 one-time pilot for 100 pieces, then $250 to $3,500 per month by volume; full details are on the [pricing page](https://trysincerely.com/pricing). Formats today are postcards and letters printed through Lob, plus handwritten notes to US addresses that Handwrytten fulfills, priced per card on your plan. So the handwriting pick above and this one are the same ink bought two ways: direct is cheaper if you only want cards, and Sincerely is the choice if you want the campaign and the holdout around them. Sincerely does not do gifts, so if that is the need, use the picks above. ## Which is better for your team - You send gifts and swag to booked meetings and customers: Sendoso. - You mail thousands of templated postcards on triggers, cheaply: Postalytics. - You have engineers and want mail as infrastructure: Lob. - You send a handful of short personal notes per rep per week, with no campaign around them: Handwrytten, bought direct. - You run outbound to named accounts and your CFO asks what the mail actually caused: Sincerely. - You send fewer than 20 pieces a month total: no software. Buy stamps and write them yourself. Most teams need one category, not five. Pick the tool that kills your actual problem: proof beats postage. --- Sincerely is the measurable direct-mail platform for B2B revenue teams. One workflow. One invoice. One report.
