Commercial printing, whether you send one letter or a whole list.
Up to 100 recipients per batch. Only sending one letter?

Upload a recipient CSV for either approach. For a shared PDF, you can also select saved addresses or combine them with your CSV. Personalized template fields need their corresponding values in the CSV.

Choose a saved letter template. Match CSV columns to its fields so names, references, or other details change for each recipient.
Uploading a PDF does not personalize the words inside it.
Prepare and review
01 · PREPARE
Your PDF or saved template, recipient addresses, and a return address. For template fields, include the corresponding values in your CSV.
02 · CHECK
Review accepted recipients, duplicates and flagged address issues. Resolve problems before paying. Address checks cannot guarantee delivery.
03 · CONFIRM
Check the letter preview and order summary. A personalized template proof shows a sample recipient’s letter, not every version.
Batches support up to 100 recipients and a $1,000 order total. Prepare a larger mailing as separate batches. Mailing for an executive, a board or a client list? See how Postmarkr works for executive assistants. See the full mailing process.
After payment
Postmarkr handles printing and USPS handoff. Your account shows processing milestones and USPS scan updates when available. Open the batch to review individual letters and any reported problems.
Carrier scans can be delayed or missing. A scan is not proof that the recipient received or read your letter.
Printing, the envelope, USPS First-Class postage, an added address page and the per-letter processing fee. Your actual total follows your document and settings. For postage alone, see USPS rates.
Include recipient names and mailing addresses. Add the values needed by personalized template fields. Use the sample CSV and column mapping in the mailing flow to match your file to its required fields.
A batch uses one shared PDF or one letter template. It does not attach a different uploaded PDF to each recipient. Use a template when details inside the letter need to vary.
Need to stop a letter after paying? Contact support right away and we'll try to catch it before it prints. Once a letter is queued for production it usually cannot be stopped, which is why the preview and total come before payment.
If USPS confirms a letter was lost, we'll resend it for free. If there's a print quality issue, we'll reprint and resend for free. Mail returned as undeliverable because of an incorrect or incomplete address is not eligible for a refund or free resend. Read the refund policy.
Your documents are processed automatically. We never read or review the content of your mail. Documents are encrypted in transit and at rest. Read the privacy policy.
This page covers First-Class letters. Certified Mail and postcards are not available as new orders. Compare mailing options if your requirements differ.
