Expected Behavior
MailChimp usually makes a single request within seconds of a URL being shared, without crawling further. Traffic rises and falls with sharing activity, so a widely circulated link can produce a sharp burst of fetches.

Frequently Asked Questions
Should I Block MailChimp?
Usually not. Blocking MailChimp may leave shared links without a title or image, making them less inviting to click. If it begins fetching at unexpected volume, try rate limiting before blocking it outright. Almost none of the top websites we track currently have robots.txt rules for MailChimp.
Does MailChimp Follow Robots.txt Rules?
No. MailChimp is not expected to follow robots.txt directives, so a disallow rule only communicates your preference. Enforce the block with firewall or server rules, then use Agent Analytics to verify that its requests stop.
Does MailChimp Access Private Content?
No. MailChimp has no credentials and should access only the public URL and assets needed for a preview. It does not continue through the rest of your site.
Why Is MailChimp Visiting My Website?
Someone shared a link to your page. MailChimp fetched it to build a preview card, and each new share may trigger another request. A spike often means your content is circulating more widely.
How Can I Tell if MailChimp Is Visiting My Website?
Agent Analytics tracks MailChimp visits in real time alongside every other known AI agent, crawler, and scraper. You can also check your server logs for requests whose user-agent string contains "MailChimp". Look for a page and its preview assets being requested without follow-up navigation. Because MailChimp does not publish a verification method, any client can claim its identity and a log match is only a clue.
