How to Check Links Before Sending an Email Campaign

A broken or misdirected link can derail an otherwise polished email campaign. Use this pre-send checklist to verify where important links go, confirm the destination pages load, and catch issues that only appear in an email preview or test send.

Key Takeaways

• Check every link’s intended destination, not just whether it opens.
• Confirm the final page loads over HTTPS and works as expected.
• Give calls to action, preference pages, and unsubscribe links extra attention.
• A URL status check is a useful signal, not proof that every subscriber can access a page.
• Test the email itself on mobile and in the email preview or a test send.

A Repeatable Pre-Send Link Checklist

Work through these checks for every campaign. Keep a simple link inventory—a spreadsheet or review document is enough—with the link text, intended destination, and check status.

1. Confirm each link goes to the right place

For each linked button, phrase, image, or footer item:

• Compare the destination with the campaign brief or approved page.
• Open the link and confirm the page matches the link text and surrounding copy.
• Check that product, offer, location, and other campaign details are correct.
• Review tracking parameters, such as campaign tags, if you use them. Make sure they have not changed the destination or introduced a typo.
• Check redirects. A link may pass through a tracking or redirect URL before reaching its final page; verify the final destination is the one you intended.

Do not treat a familiar-looking domain or a successful click as sufficient. A URL can load perfectly and still point to the wrong page.

2. Check HTTPS and page availability

Make sure the destination uses https:// when the site is expected to support it. Open the page in a browser and check for certificate warnings, errors, or an unexpected redirect. Then confirm that the page content loads and is usable—not merely that a server responds.

A URL status checker can help identify response codes and obvious availability problems. However, its result is only one check:

• A 200 response does not prove that the page contains the right content, works in a browser, or has no broken elements.
• A redirect response may be expected, but you should inspect where it leads.
• A timeout, error, or blocked response might be caused by access restrictions, bot protection, authentication, regional rules, or temporary server behavior. A checker may not access a page the same way a subscriber’s browser can.
• Some pages rely on browser-side scripts or a logged-in session, which a basic status check may not evaluate.

If the checker and browser disagree, investigate rather than assuming either result tells the whole story. Test with the access level your intended recipients will have.

3. Prioritize links that can affect the campaign most

Check every link, but review these especially carefully:

• Primary calls to action: Confirm each button reaches the intended product, offer, signup form, or article. Check that the page still reflects the email’s message.
• Preference pages: Open the page and confirm subscribers can reach the expected options. If it uses a subscriber-specific link, test with an appropriate test profile.
• Unsubscribe links: Confirm the link is present and reaches the intended unsubscribe experience. Use a test contact or test environment so you do not accidentally unsubscribe a real subscriber or yourself from a live list.
• Secondary links: Check linked images, navigation items, social links, and any URLs in the footer. A linked image should lead to the same relevant destination as its accompanying call to action when that is the intended design.

4. Test the complete email, not just the URLs

A destination can be correct while the email still makes the link difficult to use. Send a test email or open the campaign in your email platform’s preview, then check the rendered message on desktop and mobile.

In the actual email experience, verify that:

• Buttons and linked text are visible, readable, and easy to tap.
• Links are attached to the correct words, buttons, and images.
• The email has not rearranged content in a way that makes a link misleading.
• Tracking or redirect links work from the email, not only when copied into a browser.
• The destination behaves as expected after opening it from a mobile device.

Where possible, test in the email clients and devices your audience commonly uses. A preview is helpful, but a real test send can reveal behavior that a URL-only check cannot.

A Simple Pre-Send Review

Use this sequence for each campaign:

1. Inventory: List every linked element, including buttons, images, and footer links.
2. Verify intent: Compare each link with its label and the approved destination.
3. Check the destination: Open it, confirm HTTPS where applicable, follow redirects, and review the final page.
4. Check availability: Use a status check as a signal, then investigate errors or results that conflict with a browser test.
5. Review critical links: Give calls to action, preference pages, and unsubscribe links a separate check.
6. Test the email: Send a test or use the email preview; inspect desktop and mobile layouts and click through from the message.
7. Record completion: Mark each link as checked and note any issue that needs fixing before scheduling.

If a page is intentionally unavailable to the public—for example, a gated or subscriber-specific page—record how it was tested and use an appropriate test account. Do not treat an access-denied response from a public checker as automatic proof that the link is broken.

Common Mistakes

• Checking only whether a link returns a response. A response code cannot confirm that the destination is correct or that its content works.
• Ignoring redirects. A short or tracked URL may land somewhere unexpected. Check the final page.
• Testing only desktop. Small tap targets, crowded layouts, or mobile-specific page issues can be missed.
• Forgetting image links and footer links. Review linked elements throughout the email, not only the main button.
• Testing a live unsubscribe with a real subscriber record. Use a suitable test contact or environment to avoid changing a real subscription.
• Assuming the preview validates every email client. Preview tools help, but a test send and representative device checks provide additional coverage.

Best Practices

• Keep a reusable checklist and link inventory for each campaign.
• Have someone else review high-priority destinations when practical; a second reader may spot a mismatch between the copy and the landing page.
• Recheck links after editing or replacing campaign content. A final change can introduce a typo or leave a button pointing to an old page.
• Treat status-check results as diagnostic clues, not guarantees about subscriber access.
• Confirm that the landing page delivers the information or action promised in the email.

Conclusion

Checking links before sending an email campaign means verifying both the destination and the experience subscribers will have. Confirm the important pages load and match the message, then test the actual email on desktop and mobile before scheduling it.
