Build, preview and price your mailing

Nothing leaves your browser in this prototype. In production, your list is uploaded over HTTPS, verified, and only mailed after you pay and we review the order.

Postcards cost less and get read. Letters fit more words.

Format

Mail class

Marketing Mail (USPS) is cheaper but slower (about 7–21 business days), has no postcard 4×6, and needs at least 200 pieces. First-Class is faster; USPS gives no delivery guarantee for either class.

4Your message

Merge fields fill in from each row of your list. Business fields fill in from step 2.

Front headline Message (back of postcard / letter body)

Required disclosure / offer terms (small print) Front artwork (optional PNG or JPG — preview only; final art must be 300 DPI at exact size)

Remove duplicate addresses (you are billed once per address)

Format check only here. In production we also run USPS-standard address verification (and move-update) on the server; undeliverable addresses are removed before you pay and you are never billed for them.

6Approve proof & confirm

Review the preview on the right (use ‹ › to check other recipients, and Front/Back).

I reviewed the proof, including the address block, return address and every merge field. I own this list or have the legal right to mail every address on it, and I will honor opt-out requests. My content is truthful and contains no prohibited content (see the Content Policy): no guaranteed returns, no deceptive financing or "we buy houses" claims, nothing unlawful. I am responsible for legal review of my copy and offer, and for any licenses or disclosures my business or state requires. PostDirect US does not give legal advice.
