Asking to click a link in an email is unreasonable in this context. The email list is the official channel and project participants are expected to use it. They are not expected to have a web browser. The popularity of the linked site is irrelevant. Part of filing good bug reports is understanding a project’s communication style. A link to supplementary information is fine. But like a Stack Overflow answer the email should stand on its own.
