Mail Club Shipping, Explained: 2026 Postage Rates and Real Stamps
Part of How to Start, Run, and Grow a Mail Club
Most mail clubs ship the simplest way the Postal Service offers: a flat First-Class envelope with one beautiful stamp. $0.82, anywhere in the country, no software, no labels, no tracking numbers to babysit.
The whole rate picture, checked July 2026:
| What you’re mailing | Weight | Price |
|---|---|---|
| Standard envelope (letter) | 1 oz | $0.82 |
| Letter, each additional ounce | up to 3.5 oz | + $0.29 (2 oz = $1.11, 3 oz = $1.40) |
| Nonmachinable letter (rigid, lumpy, wax-sealed) | any | + $0.49 surcharge |
| Large envelope (flat) | 1 oz | $1.69 |
| Flat, each additional ounce | up to 13 oz | + $0.29 (2 oz = $1.98, 3 oz = $2.27) |
| International letter (Global Forever) | 1 oz | $1.75 |
| Postcard | one side of a postcard! | $0.65 |
Rates come from the USPS price list and change roughly once a year. Now the parts that decide which row your club lives in.
Letter, flat, or package: what your envelope actually is
The Postal Service prices by shape first and weight second, and the lines between shapes are exact:
- A letter is up to 6-1/8” tall, 11-1/2” long, and 1/4” thick, up to 3.5 ounces. This is the $0.82 world, and most mail clubs live here happily.
- A flat (large envelope) is anything bigger, up to 12” by 15” and 3/4” thick, up to 13 ounces. Art prints that can’t fold ship as flats: $1.69 for the first ounce.
- A package is anything thicker, rigid, or heavier, and it plays by different rules entirely. More on that at the end, briefly, because most clubs never need it.
The design lesson hiding in those numbers: an envelope that stays under 1/4” thick and one ounce costs less than half of one that doesn’t. Your postage line is decided at the design table, long before anyone licks a stamp.
Stamps, chosen on purpose
A printed postage label does one job: it gets the envelope there. A real stamp does two: it gets the envelope there, and it is the first beautiful thing your member sees. For a club selling the experience of real mail, the stamp is not a cost line. It is packaging, branding, and delight, priced at exactly what the boring option costs.
Practical stamp craft:
- Buy by the sheet or coil at any post office or usps.com. The catalog rotates constantly; there is a stamp for nearly any club theme.
- Mix denominations for odd totals. A two-ounce envelope wants $1.11: one Forever stamp plus one additional-ounce stamp ($0.29), or any pretty combination that reaches it. Two Forever stamps work too; they just overpay by 53 cents, fifty times a month.
- Forever means forever. Forever stamps bought at any old price still cover a one-ounce letter after every rate rise. When a price change is announced, stocking up is free money.
What quietly raises your postage
Four things move an envelope out of the $0.82 row, and every one of them is a design choice:
- The second ounce. $0.29 more, every envelope, every month. Weigh before you fall in love with cardstock.
- Rigid inserts. A backing board or an inflexible print can make a letter “nonmachinable”: add $0.49.
- Lumps. Wax seals, buttons, pressed flowers, anything that keeps the envelope from bending smoothly through the sorting machines: add $0.49, and sometimes a chewed-up envelope besides. If the lump is the point, design for it knowingly.
- Size. Square envelopes and oversized shapes charge the nonmachinable surcharge too, and past the letter limits you’re in flat territory at double the postage.
All of these are choices with price tags, and the club that knows the price tags picks its delights on purpose.
What your inserts actually weigh
You can guess your row before you ever touch a scale. A letter gets 3.5 ounces before it stops being a letter, the first ounce is $0.82, and every insert spends part of that budget. Here is what the usual mail club contents weigh, so you can add them up in your head:
| What’s going in the envelope | Ballpark weight |
|---|---|
| Sheet of standard printer paper (letter size) | ~0.16 oz |
| Sheet of nicer writing or stationery paper | ~0.25 oz |
| Cardstock postcard (4×6) | ~0.15 oz |
| Art print on cardstock (5×7) | ~0.2 oz (an 8×10 is closer to 0.5 oz) |
| Sticker sheet, kiss-cut | ~0.15 oz (4×6), ~0.3 oz (full letter size) |
| Single die-cut vinyl sticker | ~0.07 oz |
| Trading card or business card | ~0.05 oz each |
| The outer envelope itself | ~0.2 oz (a 5×7 invitation envelope ~0.25 oz) |
The row people forget is the last one: the envelope counts too. A cover note on nice paper, one art print, a sticker sheet, and the envelope holding them lands right around a single ounce, which is the exact edge where the second ounce ($0.29) decides whether to show up. That is why you weigh the finished thing instead of trusting any table, including this one. Paper weights swing by brand, and every size you pick nudges the number. Choosing what goes in your first mailing is really choosing your postage row: pick the contents, then weigh them.
A few more regulars, for when an edition gets fancy:
- Bookmark (cardstock): ~0.07 oz
- Wax seal: ~0.1 oz, and it turns the envelope nonmachinable (+$0.49)
- Teabag or single seed packet: ~0.1 to 0.2 oz, and it is no longer paper, so an international copy now needs customs forms, plus it’s nonmachinable
- Pressed flower, confetti, or a sprig of something: almost no weight, all lump, straight into the +$0.49 nonmachinable surcharge
Mailing internationally
One Global Forever stamp ($1.75) sends a one-ounce letter to any country on earth, which is a genuinely good deal. The math: an international member costs 93 cents more per month than a domestic one, which is why most clubs either charge a $2 to $3 international surcharge or fold it into a single worldwide price.
The honest complexity line: paper is easy; things are not. A letter, a print, a sticker sheet travels with no paperwork. The moment the envelope carries anything that isn’t paper (a trinket, a teabag, a seed packet), customs forms enter the picture, and that is its own afternoon of reading. Many clubs solve it by keeping international editions paper-only.
When a package happens
Some clubs mail a box once a year (an anniversary edition, a holiday extra), and that is the one moment labels and tracking exist: packages ship with printed postage, get tracking automatically, and cost several times a letter. Treat it as an event with its own price, not the club’s rhythm. For the everyday envelope, the stamp remains unbeatable.
Mail club shipping: quick answers
Does First-Class letter mail have tracking? No, and it never has: letters and flats travel without tracking, which is part of why they’re cheap. Mail club members know how mail works. The rare package edition can carry tracking when it matters.
How do I know what my envelope weighs? Build one real, complete envelope (contents, seal, stamp placement and all) and weigh it: a kitchen scale at home or the counter scale at any post office. Do it before you price your club, and again any time the contents change.
What is the cheapest way to mail fifty envelopes? Fifty Forever stamps: $41, no account, no software, no minimums. Commercial discounts only start mattering for packages; for flat one-ounce envelopes, the stamp IS the good rate.
Do stamps expire? Forever stamps never do, and they survive every price increase at full value. Buy the designs you love when you see them.
Weigh one envelope, then relax
Shipping is the part of a mail club that scares people first and costs surprises last, because one habit tames it completely: make the real envelope, weigh it, and design inside the row you can afford.
After that, postage is just stamps, and stamps are the fun part.
