Emails or Certificates Not Sending

IMPORTANT: If you just recently purchased/setup a G Suite domain for use with Certify'em, read this article first.

Why won't emails and/or certificates send to exam-takers?

There are a few simple reasons why some certificates why exam-takers may not receive an email:

  • Certification is not currently turned "ON" in your exam (check the Certify'em controls).

    • Note: This is not relevant if you are only Resending / Reprocessing responses. Certification only needs to be "ON" to automatically process new responses.

  • You have not specified the passing percentage you intended.

  • The user may have entered an invalid or misspelled email address.

  • The email is being sent, but is being rejected, or marked as SPAM, by the recipient's email service. To see if this may be the case:

      • Check your Gmail "Sent" mail folder to see if you can find a copy of an email to that user.

      • Check your exam's Certificate Records spreadsheet to see if you can find a record of the exam taker's submission(s).


If none of these simple reasons applies, consider these less frequent but still common issues and resolutions:

  • If many emails are being rejected or bounced back to you, or simply never arrive, you may need to adjust your email content, or possibly settings related to how mail is configured for your domain. See this support article for help.

  • You have exceeded a daily quota. In this case you should have received an email about this beforehand. Your quotas are set by Google, and will reset after approximately after 24 hours. Read this article for more on daily quotas.

      • Note: The higher quota of 1500 emails / day for G Suite users can take several billing cycles (i.e. months) to take effect for new G Suite domains with less than 6 users. So even if you're using Certify'em with G Suite, it's possible your quota is still 100 emails / day if you only recently signed-up for G Suite. See this article for more about Certify'em and G Suite.

  • You need to turn certification OFF and then ON again to see if that resolves the issue. Be sure you're logged in with the correct account when you do this (i.e. if you have both a G Suite and a personal Google account, you'll want to turn certification ON while logged in with your G Suite account to ensure you take advantage of its higher email quota).

  • If you have a large number of exam-takers responding all at once (i.e. a class of hundreds of students all submitting the Google Form/Quiz within a few minutes of one another), it's possible Certify'em could be overwhelmed and thus fail to process some of the responses. If this happens, you can reprocess these affected responses later via the Resend Certificates feature.

  • You have other Google Forms Add-ons installed and enabled which may be interfering with Certify'em (such as FormLimiter). Disable or uninstall them. For instructions on how to disable or uninstall Add-ons, see here.


If none of these common issues seem to be the cause, you should also check:

  • Do you still have "Owner" or "Edit" permissions on the Google Form/Quiz where you installed Certify'em? If not, certificates cannot be sent. If this was unintentional, have the person who now owns the Quiz add you back with 'Edit' access, or as the Owner. If that is not possible, then have that person uninstall and then re-install the Certify'em Add-on themselves.

  • Is the Certificate Records sheet shared with the same account that was last used to turn ON certification in your Form/Quiz? It's possible for these to get out of sync if you're using multiple Google accounts (i.e. work/school & personal) and have turned certification OFF and ON again. The result may be that certificates get emailed out, but are unable to be recorded in the Records sheet.

    • Example: Certification was first turned ON while logged-in with person@company.com, causing the Records sheet to be created and accessible by that same account. Certification was later turned OFF and then ON again while logged-in with person@gmail.com. When someone next makes a submission, a certificate may be emailed out, but a record of it won't be written because person@gmail.com doesn't have access to the Records sheet (only person@company.com does).

  • Has the Google Form/Quiz been moved into a "Shared Drive" (formerly called "Team Drive"). If so, Certify'em cannot operate there, as it needs to be owned by the individual who installed and authorized it. Move the Form/Quiz from the Shared Drive back to your own account's Google Drive and if needed, uninstall and reinstall it.

  • Check the Certificate Records spreadsheet for a sheet called "Errors", which may point to some other problem.

Can I Resend Missing Certificates?

Yes. If a certificate did not send for some reason (see previous section), don't fret. You can have Certify'em reprocess the original Google Form/Quiz response. Note that any issues which prevented the original certificate from being sent will still apply (i.e. incorrect passing percent specified). See these instructions for more details.
