Express delivery timeline
Express delivery is typically 1-3 business days after USPS accepts the letter. Processing usually begins within 1 business day. Express mailings use delivery confirmation, and you can require a signature at delivery when needed. You see the estimated delivery window at checkout before paying.
Top reasons to use Express
Deadlines
Court dates, government responses, or compliance notices that must arrive by a specific date.
Time-sensitive documents
Insurance packets, employment paperwork, or records requests when timing is critical.
Last-minute corrections
If a form is missing a signature or attachment and you need to send a corrected packet quickly.
Peace of mind
When you would rather pay for speed than risk standard delivery delays.
When Express is not necessary
If your deadline is a week or more away, First Class is usually sufficient. Use Express when the arrival date matters more than cost.
Express is an upgrade shown at checkout. If you need a delivery signature, you can select that during checkout as well. The total includes printing, envelopes, USPS postage, and any selected signature service. You see the exact price before you place your order.
