I caught a domain about 4 weeks ago, and have now developed a site on it. When I develop a site, I set the email as a catch all, as I find it easier to work that way. In the past few weeks, I've had a few emails intended for the old owners, which have just been deleted. However, at the weekend I received loads for the old owners. This includes: Personal and business Facebook notifications. Twitter account emails (multiple accounts). Pinterest stuff. PayPal notifications (both received and sent) eBay notifications (both sold and purchased) Notifications from various WP blogs that they also own. Updates, stats and notifications from various affiliate companies. I just deleted them all. But what would you do? Would you try to contact the previous owner, and explain that they need to change their emails, or just delete them as they come through? Maybe something else?
