How to switch from iPostal1 to your own virtual mailbox brand

From the customer's side, the move is mostly a change of login. Mail still arrives at your street address, the PMB number on their business cards still works, and the person handing over a package is still your staff. What moves is the account: the portal they log into, the sender on their notifications, and the name on the card charge.

The one piece of work that lands on the customer is Form 1583. The form a customer signed through the network sits in the network's system; a new form signed directly with your store, naming your store, puts the record in your hands. Innbocks sends the invitation under your name, prefills the form from the customer's ID, and connects them to an online notary from their phone.

• Same street address and PMB number
• New login on your domain, with notifications from your store's name
• A new Form 1583, signed from their phone with an online notary
• The Innbocks app connected to your store for scans and requests on the go

The order below keeps the counter uneventful. List sizes vary, but the sequence does not.

1. 1

   Week 1: export and import

   Export the boxholder list, clean up emails and phone numbers, and bring it to your migration call. Innbocks imports the list and sets up number pools so existing PMB numbers carry over. Nothing goes to customers yet.

2. 2

   Weeks 2 to 4: re-sign Form 1583

   Send the announcement email, then invitations in batches so your staff can answer questions as they come. Each customer uploads two IDs, reviews the prefilled form, and completes the online notary session. You approve from the dashboard as forms land.

3. 3

   Week 4: cut over

   Once most forms are approved, pick a morning. From that point, log every arrival in Innbocks. Customers still finishing their form keep receiving mail at the counter until you approve them.

Customers do not care which software runs the portal. They care that their address still works and that the new step is short. Say both in the first two sentences.

• Their address and PMB number do not change
• Where they log in changes, and notifications now come from your store
• USPS needs a new Form 1583 naming your store, signed online from their phone with two IDs
• The date by which you need it done, and what happens after that date

The email above is written to paste. Swap the placeholders, keep the deadline realistic, and put the invitation link in the same message so nobody has to hunt for it. Send a second, shorter reminder a week before the deadline to anyone who has not started.

Network partner agreements commonly carry a notice period, a defined process for closing customer accounts, and rules about how customer contact details may be used after the relationship ends. We do not summarize iPostal1's terms here because they are set per agreement and can change. The copy you signed is the one that applies.

Give notice in writing, keep a copy, and set your cut-over date after the notice period ends. If the agreement is unclear on anything, ask the network in writing and keep the answer with your migration file.

• Your street address, and the PMB numbers your customers already use
• Your CMRA registration: PS Form 1583-A stays on file with your postmaster under your business name
• How mail arrives and how the counter works: PostalMate and ShipRite keep feeding Innbocks through email intake
• Your responsibility for quarterly certification, which Innbocks now tracks for you with reminders and a task list

The Post Office does not care which portal a customer logs into. It cares that every addressee has a current Form 1583 with two IDs on file and that termination dates are recorded.
