How to Set Up Email Notifications in Coolify with Reloop SMTP
Coolify can email you when a deployment fails, a backup breaks, or a server goes offline — but only after you give it a way to send mail. This guide walks through connecting Coolify’s email notifications to Reloop’s SMTP relay. It takes about ten minutes, and the free tier covers everything a Coolify instance will ever send. By the end you will have a working Notifications > Email channel, a test…
To configure email notifications in Coolify using Reloop SMTP, follow these steps. Begin by ensuring your Coolify instance is running and you have admin access to the team you wish to configure. Next, obtain a Reloop account with a free tier (3,000 emails/month) and a domain you control to add DNS records for sending emails.
First, verify your domain in Reloop and create an API key. In the Reloop dashboard, navigate to Domains, add your domain, and complete the required SPF, DKIM, and DMARC DNS records. This domain verification process may take a few minutes to an hour. Once verified, create an API key in Reloop for later use as the SMTP password.
Next, go to your Coolify instance's Notifications page and select Email. Under Email service, choose Use team email settings. Enter a From name and From address on the domain you verified in Reloop. Ensure both fields are filled, as they are required, or SMTP will fail to enable.
In step three (optional), if you have multiple teams, configure a single SMTP provider for all teams by going to Settings Email as an instance admin. Enter the same sender and SMTP values, enable SMTP, and save. Then, for each team, set Email service in Notifications to Use system-wide settings.
In the Notifications Email section, scroll to Notification settings and choose events to receive notifications for. A recommended starting set includes Deployments: failed, Backups: failed, Scheduled tasks: failed, and Server: unreachable, disk usage threshold. After selecting events, send a test email by selecting Send test at the top of the page and entering an address to check. The message should arrive within seconds. If it lands in spam initially, mark it as not spam, and subsequent messages will appear in the inbox.
Finally, verify the delivered email in the Reloop dashboard under Logs, where you can see the delivery status and raw headers for troubleshooting.
