You are driving traffic to sites
you cannot guarantee are working.
An SSL expiry during a paid campaign turns every click into a browser warning. A DNS change for email setup breaks SPF and drops deliverability. A Mailchimp outage fires during your biggest send window. Merlonix catches all three before the campaign budget is spent.

Where digital marketing agencies take on silent risk
Campaign success depends on infrastructure you do not own.
You own the creative. You own the targeting. You do not own the domain, the hosting, the DNS provider, or the email platform. When any of those fail during a campaign, the outcome hits your performance report regardless of who caused it.
Campaign timing mismatch
SSL expires during a live campaign
Google Ads and Meta continue serving impressions to a landing page that shows a browser SSL warning. Every click is wasted ad spend. The ping monitor shows 200 OK — a valid HTTP response from a server with an expired cert — until someone opens the URL in an actual browser.
Email campaign setup risk
DNS changes for email break the site
Adding SPF records, DKIM selectors, and DMARC policies for a new email campaign means touching DNS. Every DNS edit is a chance to drop an A record, misplace a CNAME, or introduce a typo that resolves wrong on one of three major DNS resolvers. Merlonix diffs expected records against live resolution and flags discrepancies before the campaign goes live.
Send window collision
Marketing platform outages during campaigns
HubSpot, Mailchimp, and ActiveCampaign all have partial outages. When one happens during your client's scheduled campaign send, sequences stall, automation triggers drop, and the campaign window closes with half the sends queued. Merlonix monitors marketing platform status and alerts you before you start the send.
How it works
Infrastructure coverage for agencies that live by campaign results.
Merlonix watches the infrastructure layer beneath your campaigns — SSL, DNS, and vendor status — so you can verify the environment before committing budget and get alerted if it changes during the campaign window.
01
Attest each client domain
Verify monitoring authorization with a DNS TXT record or .well-known file — one per domain. Covers the primary domain and any subdomains you add. Takes under two minutes per client.
02
SSL and DNS checked continuously
SSL certificates are validated end-to-end on every check — not just expiry date but chain completeness and issuer. DNS records are confirmed against three independent resolvers so a change that resolves correctly on one but not others doesn't go undetected.
03
Marketing vendor status monitored
HubSpot, Mailchimp, ActiveCampaign, Stripe, Klaviyo, and six other common marketing platforms are polled on a continuous schedule. When a vendor incident opens, you get a notification before you start a send that depends on it.
04
Alerts arrive where your team works
Email or Slack — whichever your campaign ops team already monitors. Alerts include the domain, the check type, and the current state. No dashboard to log into. No context switching mid-campaign.
What the coverage means for marketing campaigns
Pre-campaign checks and live campaign protection.
Digital marketing agencies use Merlonix in two ways: a pre-launch verification pass before major campaign spend, and continuous background monitoring that alerts during active campaign windows. Both use the same account, the same domains, the same alert flow.
