Hummingbird or Hub: Email frequency

The Uptime pings the site every 2 minutes, if the site is down is pings every 1 minutes. Every time my site is shown as down I get an email notification. Most of the downtime errors are "Socket timeout..", and I've received 6 emails in the last 40 minutes. Would you please consider to add an option to the Hub or into Hummingbird settings to manage how frequently the Hub can send a "site down" email notification?
