Good to know
Do I see it before it is mailed?
Yes. You review the mailing proof and total price before approving. Nothing is printed or charged until a person approves.
When does my mail go out?
Approve by 10:00 PM CT for the next business-day mail date. USPS holidays are not business days, and delivery time after handoff depends on USPS.
What if an address is wrong?
You supply every address, and the AI never proposes one. We flag addresses that do not match USPS records so you can correct them before you approve.
Can I change my mind after I approve?
Yes. An approved job can be unapproved until its mail date, and unapproving puts the money back on your meter.
Is USMail.ai part of USPS?
No. USMail.ai is not USPS and not a virtual mailbox. We print your mail and hand it to USPS for delivery.
When does my letter go to USPS?
By default, letters you approve before 10 p.m. CT are handed to USPS the next business day (Monday to Friday). USPS delivery times vary. USPS handles delivery from there. There are no contracts, subscriptions or setup fees.
