Slack alerts for
SSL, DNS & uptime monitoring
Monitoring alerts in the Slack channel your team already watches.
How it works
How Merlonix delivers to Slack
Merlonix posts to Slack through an Incoming Webhook URL you create for a specific channel. Paste the webhook into a Merlonix notification channel, run the one-click test, and every matching alert arrives as a formatted message in that channel — no bot install, no OAuth app to approve.
Route different clients, asset groups, or severities to different Slack channels by adding more than one webhook channel.
Each alert message names the asset, the check that fired, and the before/after — so responders triage from the message, not a link.
A one-click test confirms the channel works before an incident, not during one.
Setup
Set up Slack in three steps
Step 1
In Slack, create an Incoming Webhook for the channel you want alerts in.
Step 2
In Merlonix, add a Slack notification channel and paste the webhook URL.
Step 3
Send the one-click test, then attach the channel to the assets or alert rules you want it to cover.
What fires an alert
The delivery channel changes; the monitoring doesn’t
Every alert carries the same context regardless of destination: which client asset changed, which check fired (SSL-certificate expiry or change, DNS-record drift, domain registration/expiry, uptime, DNSSEC, security headers, blocklist status, and more), and what specifically changed. Alerts fire on real state changes between definitive checks — not on a transient blip.
- SSL / TLS monitoring
- DNS & DNSSEC monitoring
- Domain-hijack & registrar-lock monitoring
- Security-header monitoring
Slack is one of ten delivery destinations, and Merlonix also runs on-call rotations and escalation policies so the right person is paged. See alerting & on-call →

Common questions
Frequently asked questions
Which Merlonix plan includes Slack alerts?
Slack alert delivery is available on Starter and above. You can start on the free plan and add Slack when you are on the qualifying tier.
What do Slack alerts actually contain?
Every alert carries the same context regardless of destination: which client asset changed, which check fired (SSL-certificate expiry or change, DNS-record drift, domain registration/expiry, uptime, DNSSEC, security headers, blocklist status, and more), and what specifically changed. Alerts fire on real state changes between definitive checks — not on a transient blip. The Slack message carries that same context, so a responder can triage from the alert itself.
Can I use Slack alongside other channels?
Yes. A single asset can send to Slack and other destinations at once — for example email plus a chat channel plus an on-call channel — so no alert rides on one delivery path. Merlonix supports email, Slack, Microsoft Teams, Discord, Telegram, Google Chat, a generic webhook, SMS, PagerDuty, and Opsgenie.
Do I need access to my clients’ servers to monitor them?
No. Merlonix probes each domain from the outside in — its public SSL certificate, DNS records, registration data, and HTTP responses — the same way a browser or resolver would. You add an asset by hostname; the Slack channel just decides where the resulting alert is delivered.
