What to do when the sign-in code, a team invitation or an alert email doesn't show up.

## The sign-in code [#the-sign-in-code]

The email's subject is "Your QRdx sign-in code". The code has 6 digits and works for 5 minutes.

If it doesn't arrive:

1. **Check your spam, junk or promotions folder.** Search your inbox for "QRdx sign-in code".
2. **Check the address.** Click **Use a different email** if you made a typo.
3. **Wait 30 seconds, then click Resend.** Each new code replaces the old one, so use the newest email.
4. **Use Google or GitHub** instead, if your QRdx account uses the same email address.

If you see "Too many codes requested", wait a minute. An address can request 5 codes every 15 minutes and 30 a day.

### Work email [#work-email]

Some company mail filters hold emails from new senders. Ask your IT team to let QRdx emails through, or sign in with another method.

## A team invitation [#a-team-invitation]

Ask the person who invited you to copy the invite link from the **Team** page and send it to you directly. Links expire after 48 hours. See [Create a team and invite people](https://qrdx.dev/docs/help/teams/create-and-invite).

## Alerts and the weekly digest [#alerts-and-the-weekly-digest]

- Email alerts and the digest are on Pro and Business.
- They're all off until you turn them on in **Settings** → **Notifications**. Turn them off there to stop them.
- The weekly digest goes out on Mondays at 09:00 UTC. It's skipped when there were no scans in the last two weeks and no form responses.
