You can add as many email notifications as you want, each with the type of notifications they want to receive.
If you add your JIRA or other service desks' e-mail account to your notifications, you'll automatically have an internal ticket for follow-up.
If you manage websites for several clients, you can add their e-mail addresses to each site too. That way, your clients are automatically informed.

Want notifications via SMS? No problem! We can send SMS alerts via Vonage (formerly Nexmo). You link your Vonage account to Oh Dear and you're all set.

The SMS notifications are a powerful alternative to internet-based services like Slack, Discord or webhooks - they provide an out-of-band method of receiving critical alerts.
