We all know good names are registered in multiple tld's and variations. Moving away from parking, I'm use lading pages to collect leads. Other domains I've setup product specific websites or gateway websites for vendors. As an experiment, I created catch-all email accounts on a recently purchased domain and another I've had for years as I developed websites on each. The recent purchase was the correct spelling of a "brandable" name. The other is taken in multiple TLD's and variations including dashes, extra words, geo abbreviations, etc. All email received by mistake was permanently deleted and the sender notified to update their contact information. The results after several weeks: 99.9% of email received was from vendors, including loan approval and rejection notices. I received no private information, no passwords or customer correspondence. Vendors updated quickly, responding with a thank-you. Only one call was required to a vendor that used a "do not reply" address. Results were better than I expected. I think people are cautious about what they send by email and customers us web-forms, the phone or social media to initiate contact.
