If you are not receiving e-mail notifications, it may be due to one of the following reasons.

• Settings required for e-mail notifications are not configured
• You are not receiving notifications on Kintone Portal either
• The E-Mail Notifications feature does not support the notifications in question
• You are not receiving e-mail notifications due to your mail server or mail client settings
• The same e-mail address is being used for multiple users

For the solutions to these issues, see below.

The action you should take depends on whether you are not receiving all or only some e-mail notifications.

Check that e-mail notifications are enabled in Kintone Users & System Administration and Kintone Administration.
If the Administration settings are configured correctly, next open your Personal Settings and check that Do not receive is not selected for E-mail Notifications. For details, refer to the following page.
Setting E-Mail Notifications

If you do not receive some e-mail notifications, check the following settings.

1. Open Kintone Administration.
   Opening the Kintone Administration Screen

2. From the Other category, click Feature Activation.

3. Check the settings in E-mail Notifications.
   You may not receive some e-mail notifications if Send REST API notifications by e-mail is disabled. To receive e-mail notifications also for REST API operations carried out on Kintone, enable this option.
   What Is "Send REST API notifications by e-mail"?

4. Click Save if you have changed any settings.

1. Click the Settings icon (the gear-shaped icon) at the top of Kintone, then select Personal Settings.

2. Check the E-mail Notifications settings.
   If Only "To Me" is selected, you will not receive any notifications other than "To Me" notifications via e-mail. Select All notifications if you want to receive "All" notifications via e-mail.

3. Click Save if you have changed any settings.

E-mail notifications are not sent out for notifications that are not received on Kintone Portal.
When you do not receive notifications

Some notifications, such as notifications for Likes on comments, are not sent via e-mail.
Check whether the notifications in question are supported by the E-mail Notifications feature.
Notifications that are not supported by the feature are listed in the "Note" sections in When and to Whom Notifications Are Sent.
You can also see if a notification is supported or not by triggering the notification and checking if e-mail notifications are sent.

Either of the following is possible.

• The mail server is configured to not receive e-mails with an empty "To" field
  Recipients of e-mail notifications are specified as "Bcc."
  Depending on the mail server you are using, e-mails whose "To" field is empty may be filtered out, and as a result, you may not receive the e-mails.
  Check the settings of the mail server.
• E-mails from the relevant e-mail address are not allowed
  Change your settings so that e-mails from the sender's e-mail address are allowed.

If the recipient e-mail address, date and time at which the e-mail notification is sent, and the body of the e-mail notification are the same, only one e-mail is sent.
Although Kintone notifications are sent to each users separately, e-mail notifications are put together.
Consider setting different e-mail addresses to users who receive e-mail notifications.
