Agency, platform, or DIY: three ways to run direct mail and who fits each

The short answer to direct mail agency vs software goes like this. Buy software when mail is a repeating program tied to your CRM, with sends fired by deal stages, events, or account lists. Hire an agency when you need one big creative campaign, or when nobody inside the company owns the channel. Do it yourself, with a designer, a printer, and a spreadsheet, when you mail a few hundred pieces a few times a year. Plenty of B2B teams belong in the first group and shop as if they belonged in the second.

Each option charges for something different. DIY costs your hours plus retail print and postage. A platform charges a subscription or a per-piece price and handles printing, address checks, postage, triggers, and tracking on every send. An agency charges for strategy, creative, and management, and usually buys print and postage for you. USPS sets postage by mail class and sort level, so nobody has a secret rate. The real differences are which rate your mailing qualifies for and how many of your own team's hours it takes to get there.

Direct mail agency vs software, with DIY in the mix

DIY fits occasional sends and tiny budgets

DIY means a designer or Canva, a printer, and a list in a spreadsheet. It's the right call more often than vendors admit. A founder mailing 80 letters to target accounts before a trade show doesn't need a subscription. Neither does an accounting firm sending a holiday card to 300 clients once a year.

Online printers make the mechanics easy. Vistaprint's postcard mailing service lets you upload your own list, and the quoted price bundles the card, a list fee, and USPS postage. Read its terms first. Vistaprint limits its responsibility to preparing the mailing and handing it to USPS. Everything after the handoff is between you and the post office.

Postage is where DIY gets expensive. The USPS price list effective October 4, 2026 has a Forever stamp at 82 cents. Marketing Mail costs far less per piece, with automation letters at the 5-digit sort level listed at 39.5 cents. But the Domestic Mail Manual requires a mailing of at least 200 pieces or 50 pounds, and you have to pay USPS an annual mailing fee and hand over presorted, barcoded mail to get those prices. A local printer with its own permit and presort software can get you there. That's the best argument for using one over an afternoon of envelopes and stamps. Rates move, often twice a year, so check Notice 123 before you set a budget.

DIY breaks on repetition. The first campaign is fun. By the third, the list in someone's downloads folder has drifted, nobody has run it against change-of-address data, and there's no way to tell which meetings came from the mailer and which would have happened anyway. If you stay DIY, clean the list before every drop. This guide to address verification covers what that involves.

Platforms fit programs that need triggers, tracking, and repeats

A platform earns its fee once mail becomes a process instead of an event. A postcard goes out when an account crosses a lead score. A handwritten note follows a closed deal. A gift lands when a champion starts a new job. Those sends go out one or five at a time, every week, and doing them by hand falls apart within a month. If that's the plan, read up on triggered direct mail from your CRM before you shortlist anyone.

Vendors in this category differ in what they send and in how technical the buyer has to be. Lob is a print-and-mail API aimed at developers and high volume, and it posts its pricing. When I checked in October 2026, the Developer plan cost $0 a month with postcards from about 91 cents each, and the $260-a-month Startup plan brought postcards down to about 65 cents. PFL pairs an automation platform that connects to Salesforce and Marketo with its own print operation, and it has been part of The Vomela Companies since July 2025. For gifts, Sendoso bought Postal in May 2025. Handwrytten writes notes with robots holding real pens and integrates with Salesforce and HubSpot.

Sincerely runs postcards, first-class letters, robot-written handwritten notes, and gifts from one workflow, with sends triggered from Salesforce, HubSpot, or a CSV and personalization pulled from account data in the CRM. It publishes plan prices, starting with a $199 one-time pilot for 100 pieces and running up to $4,500 a month for 3,700 pieces, as listed on August 29, 2026.

Published pricing is the exception. Most vendors here quote on request, so ask every one for an all-in cost per piece at your expected volume, including print, postage, address correction, and any overage rate. Then compare those numbers, not the plan names.

Here's what a platform won't do. It won't write your offer. The failure I'd watch for is a team that connects HubSpot, launches one decent postcard, and mails it unchanged for a year while response quietly sags. Someone inside still owns the copy, the list rules, and the testing calendar. If you can't name that person for next quarter, wait on the subscription. Our checklist for choosing a direct mail platform goes deeper on evaluation.

Agencies fit big creative campaigns and teams without an owner

An agency is the right buy when the creative is the hard part. Think a product launch with a dimensional box to 400 named accounts, custom packaging, copy that has to survive legal review, and sales follow-up timed to delivery. Or an enterprise in a regulated industry where every piece needs compliance sign-off and the data handling has to pass a security review. Or a company where marketing is two people who are already underwater.

Full-service shops like Amsive and Anderson Direct & Digital put strategy, creative, data, and printing under one roof. Plenty of direct mail agencies built their business on consumer mail, so ask any agency for B2B samples specifically, and ask whether they print in-house or subcontract.

Fees are murky. I couldn't find a credible published benchmark for direct mail agency retainers, and the retainer figures that circulate online mostly come from email or media-buying agencies. The structures, at least, are familiar: a project fee for creative, a monthly retainer for ongoing management, and a management fee layered on the printing and mailing services the agency buys at trade rates. Lob's cost guide puts agency or custom design at $2,000 and up, and that's for design alone. Ask for production and postage itemized at cost with the agency's fee shown separately. Otherwise you can't compare quotes, and you can't build a campaign cost estimate you trust.

Agencies struggle with small, frequent sends. Their work runs on briefs, rounds, and approvals, and a single note to a single champion who changed jobs doesn't fit that rhythm. They also tend to hold the list and the response file. Put it in the contract that you receive native design files and the final mailed list after every drop. If you part ways in year two, you keep your history.

Hybrid setups that hold up

Programs that last a few years tend to end up mixed. The version I'd try first has an agency build the creative system once: a few postcard templates, a letter, and a voice for gift notes. A platform then runs it every day. You pay agency rates for a few weeks instead of every month.

Another mix keeps triggered mail on a platform and sends the once-a-year oddity through a local printer. If the conference mailer is an oversized pop-up piece no platform prints, that's fine. One weird drop doesn't justify changing your whole stack.

The third version is an agency that runs a platform on your behalf. Some vendors sell to agencies directly; Postalytics, for one, has an agency edition with white-labeled client accounts. That can work well. Just ask whose account the data sits in, because "the agency's" is the wrong answer if you ever plan to leave.

Frequently asked questions

Is it cheaper to run direct mail yourself than to use a service?

For one small send, usually yes. Past a few hundred pieces, the math tilts, mostly on postage. Stamped First-Class is 82 cents at current rates, while presorted Marketing Mail letters can come in under 40 cents once you clear the 200-piece minimum, and that's assuming your own hours cost nothing. They don't. I'd drop DIY the moment the same mailing needs to happen every month.

What does a direct mail agency actually do?

Strategy, creative, list sourcing, production management, and reporting, in some combination. Some own presses. Some own nothing and coordinate printers and lettershops. Ask which kind you're talking to.

Do I need direct mail software if I already use HubSpot or Salesforce?

If you want mail to fire from CRM events, yes. The CRM holds the data and the trigger. Something connected to it still has to verify the address, merge the copy, print, and mail. For a once-a-year send, though, an export and a printer are enough.

Can I use an agency and a platform together?

You can, and it's often the strongest setup. Have the agency design templates and the platform run them. Get the contract terms on data ownership settled before the first piece mails.
