Almost every wedding postage disaster traces back to the same omission: nobody weighed a finished invitation before buying 300 stamps.
The whole process below is built around fixing that one thing early.
Know the three rates
Forever stamps are $0.78 and hold until July 2026. Beyond that, two figures matter:
- Additional ounce: $0.29 — for heavier suites
- Non-machinable: $1.27 — for squares, wax seals, ribbons, rigid inserts
These are not interchangeable. A heavy rectangular suite needs the first; a light square one needs the second; a heavy square one needs both accounted for.
Build the sample first
Assemble one complete invitation — outer envelope, inserts, ribbon, seal, everything — and take it to the counter. Ask three questions:
- Is this machinable?
- Does it need a surcharge?
- What is the total postage?
One trip now prevents reprinting envelopes later. Everything after this step depends on the answers.
Best deals on Forever stamps
Match the stamp to the suite
| Theme | Stamp style |
|---|---|
| Modern minimalist | Clean lines, restrained palette |
| Classic elegance | Roses, gold accents, calligraphic forms |
| Rustic or boho | Wildflowers, vintage illustration |
| Beach or destination | Shells, watercolour blues |
Test the chosen stamp on an actual envelope before committing. Colours that read beautifully on screen can disappear entirely against dark or heavily textured paper.
Count with a buffer
Total invitations + 10% = stamps to buy. The buffer absorbs address changes, envelope errors, and the copies you keep for yourself. Five spare is a nuisance; five short the night before mailing is a problem.
Buy from somewhere accountable
| Source | Discount | Why it is safe |
|---|---|---|
| Post office counter | None | Certain, and they will weigh your sample |
| Official online store | None | Full design catalogue, official source |
| Verified surplus dealer | ~10–15% | Traceable stock; check credentials once |
| Established retailers | 0–5% | Face value, easy returns |
| Marketplace sellers | Varies | Only with a long trading record |
Real stamps do not go on clearance. A site offering 50% off is not a discount channel — postage does not work that way, and USPS equipment will not honour what it sells.
Address them so machines can read them
Clear fonts, standard abbreviations, high-contrast ink, non-glossy envelopes. Calligraphy is lovely and frequently unreadable to sorting equipment — a good compromise is printed addresses with hand-lettered names.
Place the stamp in the top-right corner. This is one of the few places where being creative costs money.
Time the mailing
6–8 weeks before a domestic spring or summer wedding; 10–12 weeks for a destination wedding. Add a buffer week if the mailing falls near a major holiday, when volumes surge and your RSVP window is what absorbs the delay.
Send a pilot batch
Mail 10–20 invitations first and ask those recipients to confirm arrival and condition. If they arrive intact and on time, send the rest.
It costs a few days and catches the problems that only appear in transit — smudging, damage, unexpected postage due — while they are still fixable across twenty envelopes rather than three hundred.

The short version
Assemble one, weigh it, then buy. Add 10%, test the design on real paper, address for the machine, and pilot twenty before you commit three hundred.
