What time do envelopes expire?Envelope expiration and reminder email notifications typically occur based on the day that the envelope was sent. The day is calculated based on the sending accounts time zone. The specific time is not guaranteed, but is expected be "close" to midnight of the day that the envelope was originally sent.
Best practice: Enter a low value for the option Number of days to warn signers before expiration, such as 3 days. Warning signers of a expiring envelope improves the likelihood of getting envelopes to complete, rather than expiring.
