9 Best Direct Mail Software of 2026

Postalytics is built around the idea that a postcard should go out the same way an email does: when a contact hits a stage in your CRM. Triggered Drip campaigns listen for that event in a connected CRM or marketing automation tool and mail a piece to the triggered contact, while Smart Send campaigns mail a list you import or upload. The free plan is unusually complete, with unlimited campaigns, templates and lists, the editor and proofer, IMB tracking, personalized QR codes and pURLs, and the Direct Mail API, all priced per piece with print and postage included. Marketer at $199 per month adds suppression lists, enhanced dashboards, every integration except Salesforce and lower per-piece rates. Pro & Agency at $399 per month adds Flows for multi-touch sequences, a Response Center, unlimited users, Salesforce, webhooks and a white-label option for agencies. The catch is that Salesforce users must budget for the top tier, and the free plan stops at one login.

Thanks.io stands out for price transparency: the pricing page lists every product and every plan rate, and postage is included. A 4x6 postcard costs $1.18 on pay as you go, $0.77 on the $49 Business plan and $0.64 on the $199 Professional plan, and the same table covers 6x9 and 6x11 postcards, windowed and windowless letters, notecards and magnetic Magnacards. Business and Professional add Standard Mail, gift card sends and CRM automations, and every tier includes the full API and an MCP Server. Newer extras include a Canva integration, AI design tools, a 24/7 AI Receptionist number printed on mailers and a Lead Feed of intent leads at $0.10 each. Limits to note: pay as you go is First Class only, gift cards need a paid plan and dedicated success management starts at Professional. For teams that mainly need postcards and notes at a predictable cost, it is the easiest platform here to budget for.

Lob is the infrastructure pick on this list: an API-first platform for postcards, letters and checks that also offers a no-code design suite and address verification. Plans are sized by annual mail volume. Developer is free for up to 6,000 mailings and 1 user, Startup costs from $260 per month for up to 75,000 mailings and 3 users, Growth from $550 per month for up to 150,000 mailings and 5 users, and Enterprise is custom for larger programs. Print and postage are billed on top, starting at $0.905 per postcard on Developer and $0.615 on Growth. Every plan includes in-transit tracking and an analytics dashboard, while no-code integrations start at Startup and custom envelopes, specialty formats and HIPAA support are Enterprise only. Marketers who do not have engineering help will find Postalytics or Thanks.io quicker to start with, but teams sending tens of thousands of pieces a month get volume pricing and tooling few rivals match.

Poplar targets online brands that want mail to behave like a performance channel. The free plan already covers CSV uploads, audience management, real-time attribution, delivery tracking, lookalike modeling and email-to-address retargeting, so a store can test mail without a subscription. Lite at $249 per month adds a dedicated account manager, site visitor retargeting, dynamic creative and lower piece prices, and Pro at $499 per month adds strategic support and custom data sourcing. Per-piece prices are published for each tier: a 4x6 postcard is $0.73 on Free, $0.66 on Lite and $0.55 on Pro, with letters, bifolds and trifolds listed too. Integrations focus on the ecommerce and lifecycle stack, including Klaviyo, Shopify, Braze, Iterable and Segment, and the company cites SOC 2 Type II compliance. B2B teams that live in a sales CRM will find fewer native hooks than Postalytics offers.

LettrLabs mixes printed postcards with robot-handwritten mail, and it leans into triggers that matter to local businesses. The free Starter tier covers delivery tracking, handwritten mail merge, address and delivery verification, CSV upload and open API access, with a 4x6 postcard at $0.76 and a handwritten card and envelope at $2.86. Premium at $399 per month adds real-time automations, native integrations and webhooks, real-time attribution, multi-touch and storm-triggered campaigns, on-demand list building, multiple users and the MailGPT copy and design agent, and its rates fall as low as $0.54 per postcard with a spend commitment. Enterprise adds holdout and A/B testing and a done-for-you service. Shopify and Klaviyo appear on the integrations page. The trade-off is that automation, the core reason to buy, sits behind the Premium fee, and the best handwritten rates need committed spend.

PostGrid is an API-first service for teams that send letters, postcards and checks programmatically, whether invoices, statements or marketing mail. The Starter plan costs $0 per month and covers up to 500 mailings and 50 checks a month for 1 user and 10 templates, with published per-piece prices that include printing and postage: $0.902 for a 4x6 First Class postcard, $1.059 for a B&W First Class letter and $1.18 for a check. Certified Mail, return receipts and USPS Priority Mail express delivery are priced on the same page. Integration pages cover Salesforce, HubSpot, Zapier, Marketo, QuickBooks, Klaviyo, ActiveCampaign, Customer.io and Stripe, and PostGrid also sells address verification. Enterprise unlocks unlimited users, HIPAA compliant mailing, NCOA, custom envelopes and SSO at a custom price. Marketers without developers will find the workflow less guided than Postalytics, and anything beyond 500 pieces a month means talking to sales.

Sendoso is a gifting and sending platform rather than a postcard printer, and it fits teams that want to put a physical gift in front of a target account. Two entry plans split the use cases: Start with Merch for sourcing and shipping branded swag, and Start with Gifting for marketplace gifts and global eGifts, each with 5 licenses. Core, with 10 licenses, adds unlimited and bulk sending, storage and fulfillment in one region, event fulfillment, Campaign Studio projects and the SmartSend and SmartMessage tools. Advanced, with 50 licenses, adds a second region, unlimited Campaign Studio, kitting, the Oso AI agent and unlimited integrations, and Enterprise adds governance features such as a policy center, SCIM and anti-bribery controls. The integrations directory covers Salesforce, HubSpot, Salesloft, Marketo and 6sense. The drawback is cost visibility: Sendoso quotes each plan, and the cheaper tiers restrict sends and integrations.

Handwrytten does one thing: it writes notes with robots holding real pens and mails them, so a thank-you or birthday card looks handwritten. Single cards retail at $3.75 plus postage. Consumer plans start at $100 per month for 24 cards with a 10% discount and roll over unused credits. Business plans billed annually run from Pro at $374 per month with cards at $1.99, through Enterprise at $540 with $1.49 cards, Elite at $707 with $1.29 cards and Agency at $2,082 with $1.19 cards. Every business plan includes QR code tracking, automated birthdays and anniversaries, multistep campaigns, unlimited custom card designs and API access, and Pro adds Salesforce, HubSpot, Shopify and Blackbaud support. The limits are cost and scope: postage is extra on every card, the platform fee is high for occasional senders and there are no postcards or letters at volume.

Reachdesk is a gifting platform for B2B revenue teams that want to send gifts, eGifts and swag across regions and tie them to pipeline. Unlike most gifting vendors it publishes a floor price: plans start at $20,000 per year, with Core, Plus and Premium packages that include 5, 10 or 15 users and access to one, two or three gifting territories across the Americas, EMEA and APAC. Fulfillment centers sit in the US, Canada, UK, EU and Australia, and each package includes Amazon Marketplace access, an eGift card store, unlimited Reachdesk-sourced SKUs, unlimited GTM integrations and in-app landing pages, plus a dedicated CSM, onboarding manager and solutions engineer. Reachdesk also offers a 5x pipeline ROI guarantee for the first year, subject to its terms. The downsides are the entry price, caps on externally sourced SKUs and a focus on gifts rather than printed mail, so postcard programs belong elsewhere.
