Alert notifications from Mackerel can be sent via email.
The notification will include a link to the alert, the service or role to which the offending host belongs, and any associated graphs.
Adding email alert notifications
To add a new Email notification channel, click on “Monitors,” then “Channel Settings,” then “New Channel”. Choose Email notification from the list of integrations and give the new notification channel a name. (e.g. "email to team")
You can select individual email addresses or users belonging to an organization as recipients of emails.
When emails are not delivered (About the bounce list)
If a delivery failure occurs for recipients in an email notification channel, those email addresses may be added to a bounce list. Once added to the bounce list, emails will no longer be sent to those addresses.
Notifications for bounce list registration
When an email address is added to the bounce list, a notification email will be sent to the organization owner.
Subject: [Mackerel] Failed to send to some users belonging to "Organization Name" organization
