Broken links destroy trust, kill conversions, and signal low-quality email to spam filters. Campaign Cleaner checks every URL before your campaign goes out.
Campaign Cleaner extracts every URL from your email HTML, validates each one with a live HTTP request, checks destination domains against spam blocklists, and delivers a complete link health report before you send.
Quick Overview of Features
Every link in your email represents a conversion opportunity - a path from the recipient's inbox to the action you want them to take. When that link is broken, the path disappears. The recipient clicks with intent, arrives at an error page, and the moment is gone. Unlike a website where a user might navigate around a broken link, an email recipient has no fallback path. If the button or product image they clicked leads nowhere, they leave - and they do not come back.
Broken links discovered after a campaign goes out cannot be fixed retroactively. The email is already in millions of inboxes. Every hour the campaign remains active with broken links is another hour of missed conversions, wasted ad spend, and eroded trust. The only reliable protection is a comprehensive link check before the send - validating every URL, not just the ones that seem most important.
Spam filters do not just analyze email content - many also follow links to evaluate the destination. A URL that resolves to a 404 error, a parking page, or a known spam domain can contribute penalty points to your spam score, even if the rest of your email is clean. Phishing emails frequently contain links to spoofed pages, so filters have become adept at evaluating destination quality as part of their scoring process.
Domain reputation is evaluated at the link level. If your email contains a link to a domain that appears on a spam or phishing blocklist - even a secondary link to a third-party resource, a social media icon, or a legacy tracking domain - that link can affect your spam score. Senders who accumulate these signals over multiple campaigns see gradual degradation in inbox placement rates, which is difficult to diagnose without link-level analysis.
The most frequent cause of broken links is simple human error during template assembly. URLs are typed incorrectly, copied with trailing spaces, or pasted with missing protocol prefixes. In team workflows where multiple people contribute to a campaign, the risk multiplies. A link added in one version of the template may reference a staging environment URL that does not exist in production. A product page URL may be correct at build time but then removed after the item sells out before the send date.
URL shorteners are a particularly unreliable source of links in email. Third-party shortener services can expire links, shut down, or get their domains added to blocklists - none of which you have any control over after the link is added to your template. Tracking parameters appended incorrectly to URLs can create malformed links that appear valid in the HTML but return errors when followed. Link-level validation catches all of these issues before recipients ever see them.
A thorough broken link checker evaluates multiple dimensions of each URL. HTTP status codes identify hard failures: 404 means the page does not exist, 4xx errors indicate client errors, and 5xx responses indicate server problems. Redirect chains are analyzed to detect loops or excessive hops that slow page load for recipients. Timeout responses - where the server does not respond within a set period - indicate unreachable destinations. Malformed URLs with syntax errors are caught before they even reach the HTTP layer.
Beyond technical validity, link checkers also evaluate the domain of each destination against spam and phishing reputation databases. A URL can be technically valid - it resolves to a real page with a 200 OK response - but still be harmful if the domain is associated with malicious activity. This domain reputation check catches risks that a simple HTTP validation would miss, providing a more complete picture of link quality before the send.
Campaign Cleaner extracts every URL from your email HTML - from anchor tags wrapping text, images, buttons, and logos, as well as image source URLs and any URLs in tracking attributes. Each URL is sent an HTTP request to validate its response. Status codes are recorded and any non-200 response is flagged. Redirect chains are traced to their final destination and evaluated for chain length. Domains are checked against reputation databases.
The results are compiled into a pre-send report that lists every problematic link, its status code or issue type, and the exact location in your HTML where it appears - element type, anchor text, and surrounding context. This makes it fast to locate the problem in your template and fix it before the campaign goes out. Running the check takes seconds. Fixing a broken link in a live campaign takes days of damage control that could have been entirely avoided.
