What should I do if my website is on a Fastly IP range listed on Spamhaus but I don't send email from that IP?
Summary
What email marketers say8Marketer opinions

Email marketer from Quora shares that Check if your website is also listed in other blacklists. Implement security measures like a WAF (Web Application Firewall) to prevent malicious activity that might affect your website's reputation.
Email marketer from EmailService.com explains that if you use a third-party email provider, ensure they are aware of the Spamhaus listing and are taking steps to mitigate its impact. While it shouldn't directly affect you if you're not sending email from that IP, it could potentially affect your email provider's overall deliverability.
Email marketer from Cloudflare Community shares that using a CDN like Cloudflare or Fastly means sharing IPs. If one user abuses the service, it can affect the reputation of the entire IP range. If you aren't sending mail, focus on ensuring your website content is clean and doesn't trigger other blacklists.
Email marketer from Reddit shares that CDN IP blacklisting is a common issue. If you're not sending email, it shouldn't directly impact email deliverability. However, it could affect website loading speeds or accessibility for some users. Monitor these metrics and consider a different CDN provider if the impact is significant.
Email marketer from Web Hosting Talk forum responds that Shared hosting environments often face blacklisting issues due to other users' activities. If you're only hosting a website and not sending email, the direct impact is on website accessibility. Recommend contacting your hosting provider and asking them to investigate and potentially migrate you to a different IP address.
Email marketer from Gmass Blog shares that since email deliverability is separate from static content delivery, the CDN spamhaus listing will affect the ability of other websites and services being served from the same CDN but should not directly affect email sending. Check if your email is affected using deliverability tools.
Email marketer from StackExchange responds that if you're not sending email from the affected IP, the primary concern is website accessibility. Monitor your website traffic and consider alternative CDNs or hosting if the listing significantly impacts user access. Contact Spamhaus to understand the specific listing reason and if there's anything you can do to help resolve it.
What the experts say6Expert opinions
Expert from Email Geeks questions if the hard bounces are indeed due to the Spamhaus listing, noting that the listing has been active for almost a month and the IP in the bounce message is different, indicating it could be a separate issue.
Experts from Email Geeks confirm there is nothing to do regarding the Fastly+Spamhaus listing of the /24 the site is on.

Expert from Email Geeks explains that the listed IP address belongs to a Fastly range used for malware distribution, and Fastly is ignoring reports. He suggests that since the user isn't sending mail or doing outbound traffic from that IP, the listing shouldn't affect them much.
Expert from Spamresource.com explains that if you're on a shared IP range that's listed, and you're not sending email, the issue isn't *your* email, but your website. Some networks may block access to websites hosted on those IPs. Contact your hosting provider and consider moving to a different IP range.
Expert from Word to the Wise responds that if you’re on a shared IP space with email being sent from the IP you can’t necessarily get it removed if you don’t have control over that mail. The first step is to figure out what the listing is and who's responsible, then reach out to them to have them remedy the listing. If there are deliverability issues, you can isolate your account with a dedicated IP.
