LetterAgent, DocuPost, Stamps.com, and Pitney Bowes all move paper mail for you, but they serve different people. LetterAgent is AI-assistant native with per-letter quote-approve-pay and no account or subscription; DocuPost is the cheapest advertised per-letter option for US businesses; Stamps.com suits high-volume shippers with their own printers; Pitney Bowes fits enterprise mailrooms. Here's an honest breakdown.
| LetterAgent | DocuPost | Stamps.com | Pitney Bowes | |
|---|---|---|---|---|
| Best for | Individuals who want to mail a letter by asking ChatGPT or Claude | US small businesses mailing letters, postcards, and checks | High-volume shippers who print their own postage | Enterprise mailrooms |
| How you send | Describe the letter in chat; the assistant drafts, previews, quotes, and you approve and pay per letter | Upload or compose on their site or API; they print and mail it | Print postage from your own printer onto your own envelopes and packages | Postage meters and mailroom systems installed on site |
| Pricing model | Quoted up front per letter: no account, subscription, or top-ups | Pay as you go, no subscription or minimum; letters advertised from 95¢ (as shown on docupost.com) | Monthly subscription; postage on top of that | Enterprise contracts, leased meter hardware |
| What it mails | Letters only (US Certified / Canada Registered option for tracking) | Letters, postcards, and checks; certified, priority, and international options | Letters and packages: anything you can stick printed postage on | High-volume metered business mail |
| Canada support | Yes: Canadian recipients, billed in CAD with provincial sales tax added at checkout | US-focused | US-focused | Global enterprise, not per-letter consumer use |
DocuPost wins on per-letter price and business features. Their site advertises letters from 95¢ with no subscription and no minimum: for a US business mailing regularly, that baseline is hard to beat, and they layer on postcards from 99¢, check printing, bulk mail merge, and HIPAA-compliant processing aimed at law firms and healthcare. If you mail volume and want the cheapest advertised per-letter rate with deep business tooling, DocuPost is the honest pick.
Stamps.com wins for shippers who own the hardware. It charges a monthly subscription and expects you to print postage yourself: which only makes sense if you already have a printer, a postage scale, and enough volume for the discounted commercial postage rates to cover the fee. For a warehouse shipping dozens of packages a day, that's the right machine. For mailing three letters a month, you're paying a subscription to use your own printer.
Pitney Bowes wins for enterprise mailrooms. Postage meters, folder-inserters, and mailroom systems are built for companies processing thousands of pieces. Nobody should buy into that world to mail a letter to their landlord.
No account, no subscription, no hardware. There's nothing to sign up for and nothing to buy: no printer, no scale, no meter, no monthly fee. You describe the letter in a chat you already use.
AI-assistant native. The drafting, previewing, quoting, approving, and paying all happen inside a conversation with ChatGPT or Claude via the LetterAgent connector. Competitors make you learn their dashboard; LetterAgent meets you where you already type.
Canada is a first-class citizen. Canadian recipients get letters billed in CAD with the applicable provincial sales tax added as its own line at checkout: not a US service with Canada bolted on.
Quote-approve-pay per letter. Every letter shows its exact price before anything prints, with the page count verified. You approve that price, pay once through Stripe Checkout, and you're done: no balance to top up, no credits expiring.
Fair is fair: LetterAgent is in private testing, not a decade-old platform. It mails letters only: no postcards, no checks, no packages. And a per-letter quoted price that bundles printing, postage, and service will typically run more than DocuPost's advertised 95¢ baseline for a plain US letter. If you mail high volumes of simple US letters and price per piece is all that matters, DocuPost's advertised pricing wins. LetterAgent is for the person who values zero setup and mailing from inside a chat over the lowest per-piece price.
