DocuPost

Overview

DocuPost turns uploaded or online-composed documents into mailed letters, postcards, and checks, with web and API access. It is strongest for people who need flexible mail formats and options ranging from occasional sends to bulk campaigns. Its mix of per-piece charges and subscriptions can suit different workloads, but check the add-on costs and account limits before settling on a plan.

Key features

Letters, postcards, and checks

Letters support individual or bulk sending, black-and-white or color printing, single- or double-sided layouts, and mail-merge tokens. A 500-page document limit is generous for substantial packets, while the choice of USPS First Class, Standard Class, international, Certified Mail, return receipts, and Priority Mail Express gives senders control over cost and delivery needs. Priority Mail Express is stated to take as little as 1–2 days. Tracking options include USPS Tracking, Certified Mail, Priority Mail, and return receipts.

Postcards add a simpler, lower-cost format for outreach: full color and glossy, UV-resistant stock are included, with 4x6 included and a 6x9 upgrade for 15¢. Checks are also supported, including secure check stock and logo customization, though mailing checks requires Premium. Address verification is offered, and variable personalization helps tailor documents to recipients.

API, integrations, and safeguards

API access and developer documentation for generating an API token make DocuPost a plausible fit for teams that want to connect mailing to their own workflows. Listed integrations include Zapier, Clio, FileVine, HubSpot, QuickBooks Online, Xero, and Google Docs. The letter service is described as HIPAA-compliant with a signed BAA, a meaningful option for eligible business workflows. That should be weighed alongside the privacy policy's caveat that commercially reasonable safeguards cannot guarantee personal information's security.

Pricing

The Free plan costs $0/mo and provides one user, letters and postcards, and no send limits, but each mailpiece is paid separately. It retains documents for 90 days and places DocuPost branding on cover letters. That makes it useful for low-commitment or variable-volume sending, but not for users who need unbranded mail, longer retention controls, or included postage.

The per-piece plans keep the entry cost low, with important charges beyond the base rate:

• Letters: from 95¢ per mailpiece, plus 30¢ per black-and-white page or 40¢ per color page. First Class is a 23¢ upgrade, Certified Mail is $10, Priority Mail is $19, and international mail adds $2.10. This is the clearest fit for occasional letters, though options can make the final cost much higher than the starting price.
• Postcards: from 99¢ per mailpiece, with glossy full-color UV-resistant stock and 4x6 included. A 6x9 postcard adds 15¢ and international mail adds $2.10. The simple base package suits compact visual outreach.
• Checks: from $2 per mailpiece, plus 50¢ per attachment page. Logo customization and secure check stock are included, but the plan requires DocuPost Premium, so it is not a standalone low-cost choice.

Premium costs $9.95/mo for up to 25 users, U.S. business check mailing, a custom envelope logo, removal of DocuPost branding, document retention controls, and priority support ticket access. It is the practical upgrade for small teams that need those controls or checks. Enterprise costs $99.95/mo for up to 50 users, expedited fulfillment, an activity audit log, granular permissions, and dedicated customer support; its higher cost is justified only when those administrative and service features matter. Neither subscription removes the per-mailpiece charges described for the send plans.

Platforms

DocuPost is offered on the web and through an API. That combination favors browser-based operators and businesses integrating postal sends into software workflows, rather than anyone looking for a dedicated mobile app.

Who it's for

DocuPost suits freelancers, small businesses, and larger organizations that need a way to send physical documents without a minimum volume commitment. The no-send-limit Free plan can accommodate fluctuating volume, while Premium and Enterprise add branding, retention, user, and support controls as teams grow. It is less compelling for a solo sender who needs checks but does not want a monthly subscription, or for buyers who need a predictable all-in mailing cost: page, delivery, and international surcharges add up.

Pros and cons

• Pros: Letters, postcards, and checks cover several common mailing jobs in one service; bulk sending, mail-merge tokens, and API access support personalized or automated workflows.
• Pros: A 500-page letter limit and multiple USPS services, tracking, and return-receipt options suit both routine and more formal correspondence.
• Cons: Base prices are not the whole cost: pages, delivery upgrades, international fees, and check attachments are charged separately.
• Cons: Check mailing requires Premium, and the Free plan's 90-day retention and branded cover letter may be restrictive for some users.

Alternatives

Compare Direct Mail Automation Software if you want to review the category broadly. MailStream is another freemium web-and-API option with a free plan. Choose thanks.io if its no-monthly-subscription Pay as you go plan, which includes full API access, better fits your budget; gift cards require Business, Professional, or Enterprise. Direct Mail Manager may suit teams that need its Pro plan's 300 API calls per minute and unlimited address verifications, with a $199 /mo plan recommended for more than 1,000 mailers monthly. Postalytics is worth considering for campaign-oriented work: its free plan includes unlimited campaigns, templates, and lists for one user, with mail charged per piece.

PostGrid Address Verification is a more focused choice when address lookups are the priority; its Standard Essential plan is $18.00 per month billed yearly for 2,000 U.S. and Canada lookups, then $0.02 per additional lookup. PostPilot offers a free entry point with platform access and analytics reports, charging only for postcards and postage. Stannp may fit users who value a free plan with one user, one template, 50,000 contacts, and 20 virtual printer items monthly. Lob Address Verification is another freemium web-and-API option for address verification.

Verdict

Choose DocuPost if you need one service for letters, postcards, and checks, especially when variable or bulk volume, delivery choices, and API connections matter. The main reason to look elsewhere is cost predictability: per-page and delivery add-ons can raise the price, and checks require Premium. For teams that need its broader mail formats and controls, the flexible entry points make it a strong candidate; for narrowly focused address validation or the lowest possible per-send cost, compare alternatives first.
