Where the letter goesMailing address

Ultimapeak614 North Dupont HighwayDover, DE 19901

Ultimapeak takes its post at this Delaware address (ZIP 19901).

How to address the envelope

  1. Copy it exactly onto the envelope

    One address block, copied whole: 614 North Dupont Highway, Dover, DE 19901. If any line differs from the card above, start the envelope again.

  2. Add the return address

    Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.

  3. Ask for certified mail

    Take the letter to a post office counter and ask for certified mail: you get a postmarked receipt and a delivery record. Keep the tracking number and check it until it shows delivered.

  4. Keep the proof together

    Keep your copy of the letter, the receipt and the delivery record in one place. The delivery date is the one to quote if the account is billed again.

The letter, written out

Copy the letter below onto one page, fill in the name and email on the account and, if you have one, an account or customer number, and it is ready for the envelope. Our template builds the same letter on screen.
