Before the publication of the paper, both parties should reach an agreement on the way and time of notification. If you don't receive the notification before publishing, you should first check whether there is any problem with the agreed notification method, such as whether the correct contact information is provided or whether there may be communication problems. If the confirmation notice did not arrive, it is suggested to take the following steps to solve the problem:
1. Check email or other communication channels: confirm whether you may have missed the notification, and check email, SMS, telephone information and other communication channels, including spam and missed calls.
2. Contact the periodical editor or relevant personnel: If you don't receive the notice, contact the periodical editor or relevant personnel in time to explain the situation and request to resend the notice or provide other solutions.
3. Check the publication status of the paper: check the journal website or other relevant channels to confirm whether the paper has been officially published. Sometimes, even if you haven't received the notice, the paper may have been published and sent. At this time, you can ask the publishing house or periodical editor for the specific information of mailing.
4. Seek help: If the above steps can't solve the problem, you can consult academic tutors, peers or relevant professional institutions for their advice and help.
