What Postmarkr handles that manual mailing leaves on your desk.
Postmarkr includes printing, postage, and the envelope. Manual mailing requires paper, ink, an envelope, and a stamp.
Postmarkr takes a few minutes online. Manual mailing requires printing, folding, addressing, stamping, and drop-off.
Postmarkr verifies addresses before payment. Manual mailing depends on what you type or write.
Postmarkr shows mail status in the app. Manual First-Class letters usually have no app record.
Postmarkr works for one letter now and more later. Manual mailing gets slower with each piece.
Use Postmarkr when the paper copy matters but managing paper does not. Keep the source document in your workflow, then send a physical letter only when the situation calls for mail.
Upload a PDF, confirm the address, and let Postmarkr handle the physical mail.
