Certified Mail is a $5.55 fee added to whatever postage the piece already needs, and a return receipt costs $4.65 on paper or $2.91 electronically on top of that. A one-ounce stamped letter sent certified therefore comes to $6.37, or $11.02 with the paper receipt card. We do not sell it and cannot print it: SMKlog is a guest checkout for domestic parcel labels, with no letter services, no mailbox rentals and nothing that leaves the country.
Certified is never the whole price. It rides on the postage the piece needed anyway.
Every certified price is built from the same three parts: the postage the piece would have cost anyway, the certified fee, and an optional return receipt. Below are the combinations that cover most of what goes out of a small office, added up in full.
| What you are sending | Base postage | Certified fee | Return receipt | Total |
|---|---|---|---|---|
| 1 oz letter, certified only | $0.82 | $5.55 | None | $6.37 |
| 1 oz letter, certified plus electronic return receipt | $0.82 | $5.55 | $2.91 | $9.28 |
| 1 oz letter, certified plus paper return receipt | $0.82 | $5.55 | $4.65 | $11.02 |
| 3 oz letter, certified plus paper return receipt | $1.40 | $5.55 | $4.65 | $11.60 |
| 1 oz large envelope, certified only | $1.69 | $5.55 | None | $7.24 |
The electronic return receipt is the line worth pausing on. It costs $2.91 against $4.65 for the card that comes back in the post, and the saving of $1.74 per piece is real money across a run of notices. The paper card still wins where somebody downstream wants a physical signature card in a file, which is a legal habit rather than a postal requirement.
Certified Mail records that a piece was mailed and records its delivery. That record is the product. Three things it is not worth confusing it with.
A great many people searching for certified mail are trying to send a thing and want proof it arrived. For that job the parcel equivalent is a tracked label with a signature service attached, and both halves are priced below. The signature fees are USPS list prices, and the rates underneath are live quotes from our own checkout.

| Signature Confirmation, electronic | $4.15 |
| Adult Signature Required | $9.70 |

Read the two tables together and the choice gets easy. A document that needs a mailing record goes certified for $6.37 and up. An object that needs to arrive and be signed for goes on a parcel label, which on quote day started at $9.91 for a one pound book on that lane and carries scan-by-scan tracking as standard. Our page on USPS signature confirmation covers what a signature actually proves and when it is worth the fee.
Landlord notices, contract terminations and some regulatory filings specify certified mail by name, and in those cases nothing else will do. Where a rule only asks for proof of delivery, a tracked parcel with a signature usually satisfies it for a similar amount of money.
The physical form carries an article number and gets round-dated by a retail employee when you hand the piece over. That step is why certified mail cannot be finished at a kitchen table, and it is the reason we cannot offer it at checkout.
One certified letter is cheap enough not to think about. Fifty of them at $11.02 with paper receipts is $551, and switching that run to electronic receipts saves $87. Work out the per-piece total before committing to a mailing pattern.
The certified fee is $5.55, added to whatever postage the piece needs. USPS Notice 123, effective July 12, 2026, prices a return receipt at $4.65 on paper and $2.91 electronically. A one-ounce stamped letter sent certified comes to $6.37, or $11.02 with the paper card.
The paper receipt is PS Form 3811, the green card that comes back through the post with a signature on it, and it costs $4.65. The electronic version costs $2.91 and arrives as a record rather than a card. The saving is $1.74 per piece, and the card only earns its keep when somebody insists on paper for a file.
Not completely. The certified form carries an article number and has to be round-dated by a retail employee when the piece is handed over, so the process ends at a counter. That is also why SMKlog cannot produce certified mail: our checkout prints parcel labels, and nothing we sell substitutes for that counter step.
No. The fee buys a record of mailing and of delivery, and nothing else. Protection against loss or damage on a shipment is a separate service with its own price ladder, and for an object rather than a document a tracked parcel label with a signature service is usually the better structure.
