The document is done. Getting it mailed is our job.

Which mail type fits the job?

Invoices, notices, and campaigns still have to arrive on paper. Upload a PDF or import a Word file, pick a First-Class letter, Certified Mail, or a postcard, and we print it and hand it to USPS. A one-page First-Class letter is $2.05, all-in.

An honest comparison

What each mail type is for

What each one is for, when to choose it, and what you get. Letters, Certified Mail, postcards, and recurring sends go out through Postmarkr; EDDM is here so you can weigh it against mailing your own list.

First-Class letters

Send a letter Mail a list How First-Class works

Certified Mail

USPS mailing receipt · tracking number · delivery record

Best for: Legal notices, demand letters, lease terminations, and disputes — mail you may have to prove you sent.
Use it when: A statute, lease, or contract names Certified Mail, or you want USPS's own record of delivery. It travels like ordinary First-Class mail, so it isn't faster. You pay for the record.
You get: Your letter printed and mailed Certified, from the same upload and address check
A USPS mailing receipt and a tracking number for the letter
USPS scans in your dashboard, through delivery or a delivery attempt
A delivery record USPS keeps, with the recipient's signature

Send Certified Mail When Certified is required What Certified costs

Postcards

4×6, 6×9, and 6×11 inches · no envelope · front and back

Best for: Appointment reminders, sale dates, event invitations, and thank-yous.
Use it when: The message is short, isn't private, and works at a glance. With no envelope, it's read the moment it's picked up. Anything personal or financial belongs in a sealed letter.
You get: A one-page PDF for the front and one for the back
The same card to one address or your whole customer list
The same address check and print proof as a letter

EDDM & neighborhood campaigns

Every mailbox on a postal route · no address list needed

Best for: Grand openings, menus, seasonal offers — anything meant for a whole neighborhood.
Use it when: You want every home on a route, not a list of names. EDDM puts a flat piece in every mailbox on the carrier routes you choose, addressed to "Local Postal Customer".
What to know: A retail EDDM mailing needs at least 200 pieces per ZIP Code per day, and every piece must be a flat. You plan the routes in USPS's EDDM tool. Already have customer addresses? A letter or postcard to that list reaches only the people you choose.

Scheduled & recurring mail

Saved templates · scheduled sends · recurring schedules

Best for: Monthly statements, renewal reminders, rent notices, and quarterly updates.
Use it when: The same letter goes out every month or quarter, or has to go out on a set date. Save it once, pick the send date, and set it to repeat.
You get: Saved templates with merge fields, filled in for each recipient
A send date you choose, or a schedule that repeats

Six familiar mailing jobs, each matched to the mail type that fits. Wondering why these still go on paper? Read why physical mail still works.

Accounts receivable

Invoices & payment reminders

A paper copy gets the attention an inbox lost. Send one past-due notice, or the whole month's run from a CSV. Put the monthly run on a schedule so it goes out without you.

Sent as: First-Class letter

Send an invoice letter

Legal & professional

Demand letters & formal notices

When you may have to prove you sent it, send it Certified: you get a USPS mailing receipt and tracking number, and USPS keeps a signed delivery record. For everyday correspondence, a First-Class letter is enough.

Sent as: Certified Mail or First-Class

See the legal workflow

HOA boards & landlords

Owner & tenant notices

Meeting notices, dues letters and building notices to one unit or every owner on a list. Where your documents or lease name Certified Mail, send that notice from the post office.

Sent as: First-Class letters

See HOA mailing

Batch send

Mail merge & bulk lists

Upload a CSV and send policy changes or statements to everyone at once: up to 100 recipients and $1,000 per batch, each letter at the same price. Merge fields put each person's name and details in their copy.

Sent as: First-Class letters

Bigger documents

Contracts & multi-page packets

Up to 50 pages. Letters of seven printed sheets or more go flat in a large envelope for $2.50 more. Same upload, same checks.

Built for efficiency

What happens after you upload

Four steps between your file and the mailbox. You check the first two before you pay and follow the last two in your dashboard.

Step A: We check your file
Upload a PDF, or import a Word document into the letter editor. We check the page count, file size, and print quality, and warn you before you pay if something may print poorly. If your PDF is A4, we offer to fit it to US Letter.
Step B: We add the address page
Every letter gets its own address page, so your first page prints exactly as you designed it, letterhead and all. You see the finished proof, address page included, before checkout.
Step C: We print and mail it — one letter or a list
Send one letter, or upload a CSV and send up to 100 recipients and $1,000 per batch. Printed the next business day after payment. Your letter enters the mailstream by the next business day.
Step D: You follow its progress
Your dashboard shows each processing milestone after you pay, plus USPS scan updates when available.

Before your first send

Straight answers before you choose

Can I mail a letter without a printer or stamps?

Yes. Upload a PDF or import a Word file, add the recipient, and pay per piece. Postmarkr prints the letter, seals it, applies postage, and hands it to USPS. There's nothing to buy, stock, or drop off. See how it works.

How soon is my letter mailed after I pay?

Printed the next business day after payment. Your letter enters the mailstream by the next business day. From there, USPS estimates 1–5 days for USPS First-Class delivery. You'll see processing milestones and USPS scan updates in your dashboard when available.

What does a one-page letter cost?

$2.05 all-in for a one-page black-and-white letter — printing, envelope, address page, postage, and processing included — plus $0.20 per extra page. Price a bigger job with the mail cost calculator.

Do regular letters get tracking?

First-Class letters don't carry a tracking number the way packages do, but Postmarkr shows USPS processing scans in your dashboard when available, so you can see the letter moving. When you need a tracking number and a delivery record, send it as Certified Mail.

When do I actually need Certified instead of First-Class?

First-Class delivers the letter; Certified adds a USPS mailing receipt, a tracking number, and a delivery record, and it isn't faster — you pay for evidence, not speed. If a statute, lease, or contract names Certified Mail, send it Certified. Postmarkr sends both from the same upload. The Certified Mail guide covers when it's legally required.

Should I use EDDM or addressed mail for local marketing?

EDDM blankets every mailbox on a postal route without an address list — good for offers everyone nearby might use. Addressed letters and postcards go only to people you choose — better when you have a customer list. The EDDM guide has the decision rules and postage math.

When is a postcard better than a letter?

When the message is short, public, and useful at a glance: an appointment reminder, a sale date, a thank-you. Postmarkr prints postcards in 4×6, 6×9, and 6×11 inches from your own artwork. Invoices, notices, and anything private still go in a sealed letter. See current postcard postage on USPS rates.

Can I schedule a letter or set up a recurring send?

Both. In Postmarkr, save the letter as a template, pick the date it should go out, and set it to repeat for monthly statements or reminders. Scheduled batches follow the same limits: up to 100 recipients and $1,000 per batch. See batch sending.
