Question 1

What is Postmarkr?

Accepted Answer

Postmarkr is an online service that lets you send physical mail without leaving your desk. Upload a PDF, enter an address, pay online, and we print and mail your letter via USPS.

Question 2

How do I create an account?

Accepted Answer

Create a free account with your email address. You can start sending mail as soon as you verify your email.

Question 3

Do I need to download any software?

Accepted Answer

No. Postmarkr is entirely web-based. Just use any modern browser to sign in and send mail.

Question 4

What does your delivery guarantee mean?

Accepted Answer

If something doesn't arrive, we'll refund you or resend it for free. Every address is verified against the USPS database before we print, and every letter gets a tracking number so you can follow it from print to mailbox.

Question 5

Is Postmarkr right for large-scale direct mail campaigns?

Accepted Answer

We're built for small-to-medium volume — think individual invoices, legal notices, and one-off letters. If you need to send thousands of identical pieces, a service like Lob might be a better fit right now. We're working on bulk features.

Question 6

What types of documents can I send?

Accepted Answer

We support PDF documents for letters (up to 50 pages). We print on standard 8.5x11 letter paper.

Question 7

Can I send postcards?

Accepted Answer

Postcards are coming soon! Planned launch pricing: 4x6 ($1.00), 6x9 ($1.25), and 6x11 ($1.50) via USPS.

Question 8

Can I send mail outside the United States?

Accepted Answer

Not currently. We only support domestic U.S. addresses at this time. International mail is on our roadmap.

Question 9

Can I schedule mail to send later?

Accepted Answer

Not yet, but this feature is planned. Currently, mail is processed the same business day after payment.

Question 10

What happens if the address is wrong?

Accepted Answer

We verify addresses with USPS before mailing. If there's an issue, you'll see a warning and can fix it before checkout. If mail is returned as undeliverable, contact support to request a refund or resend.

Question 11

Can I send Certified Mail?

Accepted Answer

Certified Mail with return receipt and signature tracking is coming soon. Currently we support standard USPS First-Class Mail with delivery tracking for all letters.

Question 12

How much does it cost to send a letter?

Accepted Answer

A single-page letter starts at $1.50 (B&W) or $1.75 (color). Additional pages are $0.20 each (B&W) or $0.40 each (color). Plus a 2.9% + $0.30 processing fee.

Question 13

Are there any subscription fees?

Accepted Answer

No. There are no monthly fees or subscriptions. You only pay for the mail you send.

Question 14

What payment methods do you accept?

Accepted Answer

We accept all major credit cards (Visa, Mastercard, American Express, Discover) through our secure Stripe checkout.

Question 15

Can I get a refund?

Accepted Answer

If we haven't printed your mail yet, you can cancel for a full refund. After printing, refunds are only available if there's a quality issue or the mail is returned.

Question 16

What file format do I need?

Accepted Answer

We accept PDF files only. Your document must be an unencrypted, non-password-protected PDF.

Question 17

What are the size and page limits?

Accepted Answer

Maximum file size is 5 MB and maximum length is 50 pages. Documents are printed on standard 8.5x11 letter paper.

Question 18

What resolution should my PDF be?

Accepted Answer

We recommend 300 DPI or higher for the best print quality. Lower-resolution images may appear blurry, but text and vector graphics will print fine at any resolution.

Question 19

What is the difference between pages and sheets?

Accepted Answer

A page is one side of a PDF (what you upload). A sheet is one piece of physical paper. With single-sided printing, 1 page = 1 sheet. With double-sided printing, 2 pages = 1 sheet. You are billed per page, but the envelope type is determined by sheet count.

Question 20

When does a flat envelope apply?

Accepted Answer

If your letter requires 7 or more sheets of paper, it is automatically mailed in a flat 9x12 envelope instead of a standard #10 envelope. This adds a $2.50 surcharge.

Question 21

Are there address length limits?

Accepted Answer

Yes. The combined length of address line 1 and line 2 must be 50 characters or fewer. If your address is too long, try abbreviating (e.g., Street to St, Avenue to Ave, Apartment to Apt).

Question 22

How long does delivery take?

Accepted Answer

We process orders the same day, print the next business day, and mail the day after. USPS typically delivers within 1–5 business days (not guaranteed).

Question 23

Can I track my mail?

Accepted Answer

Yes. Every piece of mail includes tracking. You'll see status updates from processing through delivery in your dashboard.

Question 24

What if my mail is lost or never delivered?

Accepted Answer

Contact our support team. We'll investigate with USPS. If something doesn't arrive, we'll refund you or resend it for free.

Question 25

What does the delivery timeline look like?

Accepted Answer

After payment, your order is processed the same business day. It is printed the next business day and mailed the day after that. USPS First-Class delivery typically arrives in 1-5 business days after mailing (not guaranteed).

Question 26

What do the tracking statuses mean?

Accepted Answer

DRAFT: You're still working on it. PENDING_PAYMENT: Awaiting payment. SUBMITTED: Sent to our print partner. PROCESSING: Being printed. IN_TRANSIT: On its way. OUT FOR DELIVERY: In your local area. DELIVERED: Confirmed delivered. RETURNED: Sent back as undeliverable. Tracking updates begin when USPS scans your mail in transit.

Question 27

What if my mail shows as returned?

Accepted Answer

A returned status means USPS could not deliver the letter and sent it back. This usually happens because of an incorrect or incomplete address. If mail is returned as undeliverable, contact support to request a refund or resend.

Question 28

Can I cancel after paying?

Accepted Answer

Yes, as long as the letter has not yet been printed. Once the status moves to PROCESSING, it cannot be cancelled. You will receive a full refund for any cancelled order.

Question 29

Can I send the same letter to a list of people at once?

Accepted Answer

Not yet through the web interface, but it's on our roadmap. Right now, you'd send each letter individually. For bulk needs, reach out to us at hello@postmarkr.com and we can help.

Question 30

Do you offer discounts for sending a lot of mail?

Accepted Answer

Not at this time. Every letter is priced the same regardless of volume. Volume pricing is on our roadmap.

Question 31

Can I import addresses from a CSV file?

Accepted Answer

CSV import is planned but not yet available. For now, you can manually add addresses to your address book and reuse them.
