I've worked with many systems like this and know that notifications are too easy for individuals to ignore. Your primary action should be to open an issue in a bug tracking system, and let that system trigger the email/instant notification. This helps teams get a better picture of bug volume/impact/area over time, allows for prioritization of work and ensures issues don't get lost during major bug storms. Also, being able to link a bug conclusively to a changeset, build or a deployment ID would be very valuable. Rather than building lots of deep CI integrations, you could do this by allow users to configure your monitor to look for version numbers in server hints (headers, hidden fields, status pages, etc).
