Alert Email Deliverability
Make sure your critical alerts don't end up in spam.
An alert that lands in spam is useless. Worse, it can make you think everything is fine while an incident is ongoing. The deliverability of your alert emails is crucial.
MoniTao uses quality email sending practices (SPF, DKIM, DMARC), but some configurations on the recipient side can block or filter alerts.
Factors Affecting Deliverability
- Anti-spam filters: Filters may classify alerts as spam if they look too much like automated notifications.
- Corporate quotas: Some corporate mail servers limit emails from external sources.
- Full mailbox: A saturated mailbox rejects new messages.
- Filtering rules: Your own filtering rules may redirect alerts to a rarely checked folder.
Improve Deliverability
- Whitelist: Add our sending domain to your whitelist or approved contacts.
- Filter rule: Create a rule to mark MoniTao emails as important.
- Dedicated address: Use a dedicated email address for alerts, without aggressive filters.
Monitor Deliverability
- Test email: MoniTao allows sending a test email to verify reception.
- Send history: Check the history of alerts sent in your dashboard.
- Backup channels: Configure multiple channels (email + SMS + Slack) to never miss an alert.
