Email integration
Some tools can only send email. The Email integration gives you a unique inbound address: every email sent to it opens an alert, and a follow-up email saying the problem recovered resolves it. No webhook is needed.
Set it up
Create the integration
In EvoHub, go to On-Call → Integrations → + Add Integration, choose Email, pick an Escalation Policy and click Create Integration.
Copy the inbound address
EvoHub shows "Integration created! Send alert emails to this address:" with the address. You can copy it again later from the integration's Inbound email address field.
Each email integration has its own address, so you can create one per tool and route each to a different escalation policy.
What EvoHub reads
| EvoHub alert | Taken from |
|---|---|
| Title | The email subject (or "Email alert" if empty). |
| Description | The plain-text body. For HTML-only emails, the text with the HTML tags removed. |
| Severity | Always high. Email carries no reliable severity, so EvoHub does not guess one. |
| Fingerprint | The subject in lower case, with status words (such as DOWN, UP, ALERT, RESOLVED, CRITICAL, IS, BACK) and brackets, parentheses, colons and hyphens removed. Status words are removed only as whole words, so "Backup" and "this" stay as they are. Each email integration keeps its own fingerprints. |
Auto-resolve
An email is treated as a recovery when its subject or body contains any of these phrases as whole words (case does not matter):
resolved, recovered, is up, back up, is back, cleared, has recovered, up again, ok again, and no longer followed by down, failing, firing, alerting, critical, in alarm, unhealthy or degraded
Whole words only: "unresolved", "this backend" or "is upgraded" do not count, and neither does a plain "no longer responding".
A recovery email does not open an alert. It resolves the open alert of the same integration whose fingerprint matches — so [DOWN] api.acme.example is resolved by [UP] api.acme.example is back up, because both subjects reduce to the same fingerprint.
Warning
The recovery check looks at the body as well as the subject. If your tool's problem emails contain one of those phrases in their body (for example a footer such as "This alert will be resolved automatically"), they are read as recoveries and no alert opens. Remove the phrase from the tool's email template, or use a webhook integration for that tool.
Deduplication
While an alert is open, more emails to the same integration with the same subject (after status words are removed) are recorded as Retriggered on that alert instead of opening new ones. The same subject sent to two different email integrations opens two separate alerts. Within one integration, different monitors should have different subjects, for example by including the monitor or host name.
Security
- The address contains a random token and is not guessable. EvoHub does not check the sender, so anyone who knows the address can open alerts. Share it only with the tools that need it.
- To stop accepting email, Disable the integration. To retire an address, Delete the integration and create a new one.
- Emails to an address that does not belong to an enabled integration are ignored.
