Can you send Certified Mail online?

Yes, but "Certified Mail online" can mean two different things. USPS Certified Mail is the postal extra service that creates mailing and delivery evidence. PostalForm is an online print-and-mail workflow that lets you upload or create the document, choose Certified Mail when the mailpiece qualifies, pay online, and have the physical letter prepared for USPS.

Yes. PostalForm can send Certified Mail online for qualifying U.S. First Class mail. Upload or create the document, review the PDF, enter sender and recipient addresses, choose Certified Mail when it is available, add Electronic Return Receipt if you need a downloadable signature record, and see the price before payment.

USPS treats Certified Mail as an extra service for eligible mail, not as a standalone document-upload product. USPS says Certified Mail proves you sent the item, shows delivery or attempted-delivery status, and can be combined with Return Receipt for an electronic or physical recipient-signature record. USPS also says Certified Mail is purchased at a Post Office when a postmarked sender's receipt is requested.

That distinction matters. USPS Click-N-Ship helps with postage and shipping labels, but it is not a consumer PDF-to-letter printing service. USPS also says Return Receipt (Electronic) currently cannot be purchased through USPS.com and must be requested at the time of mailing. If you already have the paper letter and envelope, you can use USPS retail forms and Post Office help. If your goal is "upload this PDF, print it, prepare the envelope, pay online, and send it as Certified Mail," PostalForm handles the document-to-mail workflow and hands the eligible mailpiece to USPS.

• Certified Mail records mailing, tracking, and delivery or attempted-delivery events.
• Electronic Return Receipt is the optional add-on that provides a downloadable signature record.
• Use it when you need proof of delivery for legal, business, or compliance notices.
• Certified Mail is an add-on for qualifying U.S. First Class mail, not a same-day courier service.
• USPS Certified Mail forms and online-service options are not the same thing: PS Form 3800 is the Certified Mail receipt/label, PS Form 3811 is the hard-copy Return Receipt, and Electronic Return Receipt is the digital signature record.
• USPS fees and PostalForm checkout prices answer different questions: USPS fees cover postage and extra services, while PostalForm pricing also includes document handling, printing, envelope prep, provider routing, and fulfillment.

When you send Certified Mail with Electronic Return Receipt, USPS creates a record at each step:

1. Mailing receipt — Proof that the letter entered the USPS system on a specific date.
2. Tracking history — A timestamped log of the letter's journey through USPS facilities.
3. Delivery confirmation — Record that the letter reached its destination.
4. Signature — The name of the person who signed for the letter and the date they signed.

This documentation can be used in court, submitted to agencies, or kept for your own records. The Electronic Return Receipt provides the signature digitally—you don't have to wait for a green card in the mail.

Need the form-specific version? See the Certified Mail forms guide for PS Form 3800, PS Form 3811, Electronic Return Receipt, and Certificate of Mailing Form 3817.

With PostalForm, you do not need to fill out PS Form 3800 or PS Form 3811 yourself. The checkout flow shows Certified Mail and Electronic Return Receipt options when the order qualifies.

Return Receipt is separate from Certified Mail. Certified Mail gives mailing and delivery or attempted-delivery evidence. Return Receipt adds a recipient-signature delivery record.

USPS says Electronic Return Receipt must be requested at the time of mailing and is not available for APO/FPO/DPO addresses or certain U.S. territories, possessions, or freely associated states.

People often search for "electronic Certified Mail" when they mean one of two things:

1. Certified Mail sent through an online service: upload or write the document online, pay online, and have the service print and mail it through USPS.
2. Certified Mail with Electronic Return Receipt: a USPS signature proof option that gives a digital delivery record instead of a physical green card.

These are related, but not identical. Certified Mail creates the mailing and delivery/attempt record. Electronic Return Receipt is the optional signature proof record.

Certified Mail is often used when the law or a contract requires "written notice." Here are common situations (rules vary by jurisdiction):

Landlord-tenant disputes — Many states require landlords to provide written notice before eviction proceedings. Certified Mail creates proof the notice was sent and received.

Debt collection and disputes — If you need to send a written dispute, Certified Mail proves your letter was mailed on time.

Contract termination — If a contract requires written notice to cancel or terminate, Certified Mail proves you gave proper notice.

Demand letters — Before filing a lawsuit, attorneys often send demand letters via Certified Mail. The signature proves the recipient can't claim they never received it.

Government correspondence — Responding to IRS notices, state tax agencies, or regulatory bodies often benefits from Certified Mail proof.

Insurance claims — Some policies require written notice of claims or cancellations. Certified Mail creates a paper trail.

When USPS delivers a Certified Mail letter with Electronic Return Receipt, someone must sign for it. This is different from regular mail, which is simply left in the mailbox.

The signature serves two purposes:

1. It confirms a real person received the letter.
2. It establishes the exact date of delivery.

If no one is available to sign, USPS will leave a notice and hold the letter at the post office for pickup. The holding period varies and is often around 15 days before it's returned to sender.

This is important: if someone refuses to accept Certified Mail, that refusal itself can sometimes be used as evidence that delivery was attempted.

PostalForm offers Certified Mail for qualifying U.S. First Class mail:

1. Upload your PDF — From your phone or computer.
2. Enter addresses — We validate them before checkout.
3. Select Certified Mail — Add Electronic Return Receipt when signature proof matters.
4. Pay and USPS handoff — We print the letter, prepare the envelope and postage, and hand it to USPS First Class.

After mailing, you receive your USPS tracking number. If you added Electronic Return Receipt, you can access the signature record showing who signed and when after USPS makes it available.

Certified Mail appears only when the order qualifies for the service. In practice, that means the mailing must be a supported U.S. First Class letter, the sender and recipient details must be valid for the selected route, and the document must be printable as a normal paper mailpiece.

Use regular First Class or Express instead when Certified Mail is not offered at checkout. Use a courier or another service if you need physical enclosures, same-day hand delivery, or a legal-service workflow that requires personal service rather than postal delivery.

Certified Mail is usually chosen because the record matters, so the review step needs to be boring and exact. Before checkout, PostalForm shows the uploaded PDF, the recipient and sender addresses, the First Class Certified Mail option, any Electronic Return Receipt selection, and the total price.

That does not replace legal advice or the specific notice rules for your situation. It does reduce the operational risk that the wrong document, wrong address, or wrong proof option gets mailed.

Production and mailing to USPS usually takes 1-3 business days. After USPS accepts the letter, Certified Mail travels via USPS First Class, which typically takes 3-7 business days.

Certified Mail documents mailing and delivery events, but it does not guarantee a delivery date. After USPS accepts the letter, USPS handles transit and delivery.

Your tracking number becomes active after the letter enters the USPS system. Delivery confirmation and signature records appear once the recipient signs.

Not every letter needs proof of delivery. Regular First Class mail is fine for:

• General correspondence
• Documents where delivery isn't contested
• Situations where the recipient confirms receipt another way

Use Certified Mail when you need proof that something was sent and tracked through delivery or attempted delivery. Add Electronic Return Receipt when the signature record itself matters.
