Direct Mail Method Chooser
The other mailing tools on this site pick up after the class is decided — the cost calculator opens with a class dropdown, the EDDM calculator assumes you already chose EDDM. This one decides it: six inputs, one recommended method, an honest account of what that method will demand of you, and the runner-up worth pricing against it.

Speed, price, and what happens to a bad address. Marketing Mail is cheaper but deferrable — USPS publishes a service standard for it but treats it as a target rather than a commitment, and it requires a permit, at least 200 pieces or 50 pounds, and presorted barcoded addresses. It also cannot carry personal correspondence or a bill, and each piece has to stay under 16 ounces. The detail people miss is that an undeliverable Marketing Mail piece is disposed of unless you print an ancillary service endorsement asking for it back. First-Class costs more per piece but carries the tightest published standard of the two and includes forwarding and return at no extra charge. Neither is a guaranteed delivery date.
It depends on the method. EDDM Retail needs no permit — you pay at the retail counter of the office that delivers your routes. Single-piece First-Class needs nothing at all. Bulk rates, including USPS Marketing Mail and presorted First-Class, require a mailing permit at the office you mail from plus an annual mailing fee, and the mail has to be presorted and barcoded to earn the discount. On campaigns we mail, we handle the postal paperwork and the post office end — tell us the drop you have in mind and we will sort out the permit question on your quote. See mailing services.
No, and this catches people out regularly. Federal tax-exempt status and USPS nonprofit authorization are separate things decided by separate agencies. You apply on PS Form 3624 at the post office you intend to mail from, and USPS runs its own eligibility test covering religious, educational, scientific, philanthropic, agricultural, labor, veterans, and fraternal organizations, plus qualified political committees. The authorization is granted for a specific post office rather than for your organization generally, and approval is not immediate — start it well before your drop date.
CASS is the USPS certification for address-matching software. Running your list through CASS-certified software standardizes each address to USPS format and appends the ZIP+4 and delivery point code that an automation barcode is built from. NCOALink is the USPS change-of-address database, which catches recipients who have moved. USPS calls the obligation Move Update and requires that addresses were processed against change-of-address data within 95 days before the mailing date. You need both to earn automation prices on a bulk mailing — skip them and you lose the discount on the whole job.
Both pay the same postage rate, so the choice is about labor and appearance. A permit imprint prints the indicia right on the piece and pulls postage from an advance-deposit account, which makes it the cheapest to produce at volume. Precanceled stamps have to be affixed to every piece and all carry the same denomination, so they cost more to apply — but the piece reads as a stamped envelope rather than a bulk mailing, which some mailers judge worth the difference on a personal-looking letter.
Then EDDM Retail is usually the answer, because it does not use one. You pick USPS carrier routes and every address on them receives the piece. The tradeoffs are format, quantity, and control: the piece has to qualify as a flat, it carries a simplified address line such as "Local Postal Customer" instead of a name, and the quantity runs from 200 pieces at the floor to 5,000 per ZIP Code per day at the ceiling — a route is all-or-nothing, so the routes set the count rather than you. If your audience is genuinely narrow, buying a list is the honest alternative — EDDM vs. targeted mailing lists compares the two.
Behind the numbers
Everything downstream of this decision — postage, piece size, artwork, schedule — is set by one question you have to answer first: are you mailing to people or to places? Mailing to places is saturation. You choose USPS carrier routes and every mailbox on them gets the piece, with no names involved anywhere. Mailing to people means an addressed list, which you either already have or have to go buy. That fork is why this tool sits ahead of the others: the mailing cost calculator opens with a class dropdown and the EDDM cost calculator assumes you already chose EDDM. Neither one can tell you that you chose wrong.
If you are mailing a list, the real choice is between First-Class Mail and USPS Marketing Mail, and the tradeoff runs deeper than price. Marketing Mail is cheaper and slower: USPS publishes a service standard for it but treats the class as deferrable, so the schedule is a target rather than a commitment and it stretches whenever volume spikes. It also requires at least 200 pieces or 50 pounds, each piece has to stay under 16 ounces, and it cannot carry personal correspondence or a bill. The part that quietly costs real money is what happens to a bad address — an undeliverable Marketing Mail piece is simply disposed of unless you print an ancillary service endorsement asking for it back, so you pay the postage and never learn the address was dead. First-Class costs more per piece and does not start presort discounts until 500 pieces, but it carries the tightest published standard of the three plus forwarding and return at no extra charge. On a list nobody has mailed in a while, that free return is a list-cleaning service you were going to have to pay for anyway. Neither class is a delivery guarantee, so work backwards from a deadline with the mail drop date calculator rather than up to it.
Bulk rates are not something you select at the counter. They require a USPS mailing permit at the office you mail from plus an annual mailing fee, and there are three ways to actually pay the postage. A permit imprint prints the indicia directly on the piece and draws the postage from an advance-deposit account. Precanceled stamps have to be affixed to every piece and all carry the same denomination. A postage meter is the third. The method does not change the rate — it changes the labor and the look, which is the whole argument: permit imprint is cheapest to produce at volume, while precanceled stamps cost more to apply but read as a stamped envelope rather than a bulk mailing. Nonprofit prices are a separate authorization layered on top of all of it. You apply on PS Form 3624 at the post office you intend to mail from, and USPS runs its own eligibility test covering religious, educational, scientific, philanthropic, agricultural, labor, veterans, and fraternal organizations, plus qualified political committees. Federal 501(c)(3) status is not that test and does not by itself qualify you, the authorization is granted for a specific post office rather than for your organization at large, and approval is not immediate. Start that paperwork before you start the artwork.
Whichever class you land on, a list has to be clean before USPS will discount it, and two acronyms do that work. CASS — Coding Accuracy Support System — is the USPS certification for address-matching software; running a list through it standardizes every address into USPS format and appends the ZIP+4 and delivery point code that an automation barcode is built from. NCOALink is the USPS change-of-address database, and running against it catches the households that have moved since anyone last touched the file — the Census Bureau's annual mover rate has run around 8 percent of the population in recent years, which on a three-year-old list is a meaningful share of your postage going to strangers. USPS calls the obligation Move Update and sets the window at 95 days: addresses must have been processed against change-of-address data within 95 days before the mailing date. Skip it and you lose the automation prices on the whole mailing. Once the class and the list are settled, confirm the piece with the mailer size checker and find out whether the campaign can pay for itself in the direct mail break-even calculator.
