So I have an email address and I'm trying to find out the domain(s) associated with it. The problem is, the domaintools site most of you will send me to shows that there are 16 domains. That's great, but it only shows the first letter of them. It's going to cost me $140 to get the report. Does anybody either know a site that through free trials, free usage, or anything will allow me to get at least 1 of the 16 domains in its entirety? How about a site that will give me 1 of 16 for like $20? I'm in a partnership and I think my partner is "cheating" on me in the venture so I'm hoping to figure it out without paying $140 or falsely accusing him. Anything helps.
