How to remind a Dropbox Sign signer and fix an expired link

If a signature request is still pending, you can send a reminder from Dropbox Sign’s Documents page. The reminder gives the selected signer a new link. After a newer reminder is sent, only its link works. Dropbox Sign reminder instructions

Before sending anything, find the request in Documents using search or filters and check the status beside its title. That helps you avoid following up on a request that has already expired or been cancelled. How to check a signature request’s status

Check whose turn it is

A signer who has not received an invitation may simply be waiting in an ordered request. Dropbox Sign waits for one person to finish before notifying the next; the request details show each signer’s position. For an ordered request, a reminder goes to the current signer. Dropbox Sign course on sending signature requests

Suppose the fictional request “October design approval” lists Avery first and Morgan second. The sender’s own records show that Avery signed, so Morgan is now the person to remind. If Avery were still outstanding, Morgan’s wait would be expected; a reminder would not skip Avery.

If several requests have similar titles, use the request date and recipient address to distinguish them in your own records. A reply saying “I signed it” might refer to last month’s approval. Ask which document they completed before following up on the October request.

Send the reminder

For a pending request:

1. Go to app.sign.dropbox.com and open Documents.
2. Select the more options menu next to the intended request.
3. Select Email reminder.
4. Check the intended signer or signers.
5. Select Email reminder again to send it.

Review the recipient checkboxes before the second Email reminder action. How to send a reminder

If you cannot find Email reminder, first confirm that you have the intended request and check its status. The official steps do not explain every cause of a missing control. Record the request status before contacting support.

For the Avery and Morgan example, the follow-up belongs with Morgan once Avery’s step is complete. Someone copied into your ordinary email conversation may be helping coordinate the work without being a signer on this request. Use the recipients attached to the transaction when choosing the reminder recipient.

Fix an expired reminder link

Ask the signer to open the newest reminder email, especially if you have sent more than one. Dropbox Sign says older reminder links lead to an expired-link page once a newer reminder link exists. How reminder links work

Here is an illustrative timeline, not a record of delivered mail or a product test:

• Tuesday, 9:00 a.m.: The original request is sent.
• Wednesday, 10:15 a.m.: A reminder is sent.
• Wednesday, 10:20 a.m.: Another reminder is sent.
• Wednesday, 10:23 a.m.: The signer opens the 10:15 reminder link and sees the expired-link page.

In that example, point the signer to the 10:20 reminder email. Ask them to expand the individual message if their inbox groups emails into a conversation. When people are in different regions, include the timezone so “the 10:20 email” identifies the same message for everyone. If the newest link still fails, ask for the exact error and the timestamp of the email they opened. Do not ask them to forward a signing URL.

An expired link from an older reminder is different from an expired request. Once the request itself expires, its link stops working and it cannot be completed; if a signature is still needed, resend the request. A cancelled request’s links stop working immediately. Check the request’s status before telling the signer which email to use. Dropbox Sign course on sending signature requests

If the invitation never arrived

Confirm the intended address privately and ask the signer to check spam. Dropbox Sign’s guidance says invalid invitation links can involve email security settings; an administrator can review approval of app.sign.dropbox.com and mail.hellosign.com. It also suggests adding noreply@mail.hellosign.com as a contact. Use the current official guidance for any administrator changes.

Keep this separate from sender completion notifications. Dropbox Sign says a sender’s notification preferences or an account mismatch can affect completion mail, and mail from noreply@mail.hellosign.com may bounce or land in spam. A missing completion notice to the sender does not, by itself, tell you whether the signer received an invitation. Dropbox Sign email troubleshooting

If Morgan says “nothing arrived,” ask whether that means no invitation or no completed copy. Those are separate messages and may require different checks. Compare the recipient address with the one you intended to use, without asking Morgan to post their address or document in a group chat.

Follow-up emails you can adapt

These are draft messages to send through your usual email channel. They are not text entered into the Dropbox Sign reminder flow.

Ask for the signature with a clear deadline

Subject: Signature needed for [document title]

Hi [name], please review the Dropbox Sign request for [document title] by [date, time, and timezone]. We need it for [specific next step]. If that deadline does not work, please suggest a time you can review it. If the invitation has not arrived, reply privately so I can check the address I used.

Thanks,
[your name]

Use a deadline you have actually agreed on. Explaining which next step is waiting gives the signer more information than labeling every reminder urgent.

Help someone who opened an expired link

Subject: Newest link for [document title]

Hi [name], I sent another Dropbox Sign reminder for [document title] at [date, time, and timezone]. Please open the most recent reminder email and use its link; an earlier reminder link may show an expired-link page. If the newest one also fails, tell me the email’s date, time, and timezone and the exact error you see.

Thanks,
[your name]

Send the preceding wording after you have actually sent the reminder. If you have not sent it yet, first ask which message the recipient opened. Describing a nonexistent new email would add another delivery problem.

Confirm a missing or mistyped address

Subject: Checking delivery for [document title]

Hi [name], I’m checking whether the signature request for [document title] reached the right address. Please reply privately with the address you want me to verify, or tell me if you found the invitation in spam. You do not need to send me a signing link or a confidential attachment.

Thanks,
[your name]

If the address or document needs correction, resolve that before sending more reminders to the existing request. Editing and resending after someone has signed requires those signatures again and counts as a new request; completed requests cannot be edited. Dropbox’s request editing guidance

Leave a note for the next follow-up

For your own records, a working note might read: “October design approval, [request date]; intended recipient: Morgan; known current position: second, after Avery; reminder sent: [date and time, timezone]; next agreed check: [date].” This is a suggested note for your own records, not a Dropbox Sign export or dashboard field. It gives a colleague taking over the request enough context to follow up without immediately sending another reminder.
