I feel like an easier solution to having six different email addresses is to use Gmail aliases - I've caught a few less-than-honest companies either selling my email address, or been breached without disclosing such, simply by using an alias along the lines of '+service_name'. If any alias starts to receive spam you can setup rules to automatically delete everything that comes in with that. You also get the added benefit of significantly easier and more accurate search.
