proof of service by email
Keep the message behind your sending record.
Proof of service by email — Keep the message alongside the evidence that it was sent. Dating a saved copy does not establish that it was sent. Sending, delivery and an agreed service address remain separate checks.
Sending, delivery and a saved copy are separate.
A file timestamp does not establish sending, delivery, reading or an agreed address for service. Keep the raw message and transport records. For postal mail, use the proof of mailing checklist and postal evidence.
Your photos and files stay on your device, so keep them.

Now keep it safe: three things
- Keep your photos and files unedited. The receipt only matches the originals. Put them in an album such as “My records”.
- Save this receipt to your camera roll.
Keep the receipt file too. The image is a handy copy; checking needs the file.
- Email it to yourself.Email it to myself
Your mail app opens a draft. Attach your receipt image and receipt file. Don’t attach your photos or documents. Timevolt does not send it or know whether it was sent.

How to keep notes that hold up
Write notes as soon as you can. Keep the original account rather than replacing it later; the venue decides what weight it gets.
- Write it down straight away, on paper or in the box on a step.
- Put the date, time and place at the top, and who you spoke to.
- Use their words where you can; separate what you saw from what you were told.
- Sign or initial a paper note, photograph it and add the photo.
- Never edit an old note. Add a new dated entry when something changes. A device save time is not independent time evidence or proof of event order.

Back mailing claims with records of the process
A sender relied on a lawyer's sworn statement that a notice was posted. A case report says the court needed proof of a regular mailing process and its use. It set aside the sender's early win.

Keep delivery proof with a sent email copy

Check agreement to receive court papers by email
Lawyers emailed court papers on the deadline, but the other side had not clearly agreed to receive them by email. They had not asked about email limits either. A report says the court refused to treat that as valid delivery.

Positions below refer to the cited rule or record type, not endorsement of Timevolt. This service is not represented as an eIDAS qualified timestamp provider. A non-qualified timestamp does not receive the qualified timestamp presumption.
Federal civil courts
FRCP 5(b)(2)(E) and 5(d)(1)(B)
Electronic service via the court e-filing system is allowed; other electronic means need the recipient's written consent. Service is not effective if the sender learns it did not reach the person. A certificate of service is required for non-e-filing methods. Says nothing about independent timestamps.

Email service since 1 March 2021; forms RTB-34, RTB-50, RTB-44, RTB-51
RTB-34 allows service 'by email or fax to an address or number provided as an address for service'. For email it asks for proof the address was provided for service, such as a copy of RTB-51 or other written proof the party agreed. The form does not mention a copy of the sent email, screenshots or delivery receipts. The 1 March 2021 start date is not confirmed from this source.

Proves / Doesn’t prove
Proves
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.
Doesn’t prove
It does not prove the message was actually sent, delivered, opened or read, who sent it, or that an email address was agreed for service; those need delivery records, headers and the recipient's agreement.
A saved file cannot establish sending, delivery, opening, reading or an agreed address for service.
These are the bounds of a completed proof. The local tester does not establish any time. The chosen court, scheme or regulator decides what to accept.
Questions, answered plainly.
Your file stays on your device. During normal receipt creation, your device sends a randomized code made from its fingerprint, plus encrypted recovery data. It doesn't send the plain fingerprint or the random value that opens the code. Keep the original file and the complete receipt for checking. Privacy Policy.
Does a time receipt prove my email was delivered?
A completed time receipt shows that the exact selected file existed by the independently witnessed time. You can check whether a later copy has the same bytes. It does not establish creation time, authorship, identity, event order, location or the truth of the contents.

Context for this answerCan I just screenshot the email?
You can, but screenshots and headers are easy to question as edited. Saving the original .eml and getting an independent date on it makes the copy harder to dispute.

Context for this answerIs email even a valid way to give notice?
Often only if the other side agreed to it, such as an address for service in the lease or a signed form. Check the rule for your venue first.

Context for this answerWhat should I keep along with the notice itself?

Context for this answerIs this the same as a certificate of mailing?
No. A USPS certificate of mailing is an official receipt for physical mail and must be requested before mailing. Timevolt dates your saved files, it is not a postal or registered-mail service.
