You do not have to stamp 200 letters by hand. Bring the batch to the post office counter and ask for them to be metered: the clerk runs postage for the whole stack in minutes. Nonprofits mailing regularly should look at bulk or presort rates, which need a permit and minimum quantities but cut the per-piece cost substantially.
Bring your sealed, addressed envelopes to the retail counter in a box or bag and ask the clerk to meter them. They run the stack through the postage meter, which prints the postage mark directly on each envelope, and you pay for the total. It takes minutes for a couple of hundred pieces, and there is no permit or appointment involved. One thing to know: metered mail gets a different postmark than stamped mail, with the mailing date printed in the mark, which some people like for deadline-sensitive mail and others dislike for wedding invitations.
| Approach | Best for | What it requires |
|---|---|---|
| Counter metering | One-off batches of tens to hundreds | A trip to the post office; envelopes sealed and addressed |
| Postage meter at home or office | Frequent business mailings | Leased meter from an authorized vendor, refilled postage |
| Presort / bulk rates | Large recurring mailings (nonprofits, campaigns) | Mailing permit, minimum piece counts, presorted and bundled trays |
| Online mailing service | Batches with no printer, stuffer, or post office trip | Upload the letter and recipient list; the service prints and mails |
The discounted nonprofit rate is real money, but it is not a coupon you show at the counter. You need a mailing permit, authorization as a nonprofit mailer, and each mailing has to meet minimum piece counts and be presorted by ZIP code into the trays the post office specifies. First-time nonprofit mailers usually work with a mail house that owns the permits and the sorting equipment: you supply the addresses and the letter, they handle the presort paperwork. If you mail once a year, a mail house costs less than setting up the whole system yourself.
Three common ones. First, mixing weights: if some envelopes hold five pages and others hold one, they need different postage, so sort by weight before you go. Second, bad addresses: one wrong ZIP in a mail-merge of 200 means 200 returned letters, so run the list through address verification before printing. Third, sealing too early: if the clerk needs to confirm contents for a service like certified mail, unsealed envelopes save a reopening. Bring tape and seal at the counter if you are unsure.
Canada Post works the same way in principle: the counter can process a batch, and addressed admail or presort products cover large mailings with their own preparation rules. The product names differ from the USPS ones, so ask at the counter for the current business mailing options rather than assuming US terminology applies. If your 200 letters are going to Canadian addresses, a service that prints and posts from inside Canada avoids the cross-border leg entirely.
LetterAgent prints and mails single-sided 8.5x11 letters to US and Canadian addresses, with each job quoted up front. It is built for individual letters described to your AI assistant, not for uploading a 200-row mail merge: if your batch is really a set of distinct letters, each one goes through as its own job. For a true bulk mailing with presort discounts, a mail house remains the right tool. LetterAgent is currently in private testing.
