Need longassgermanword, stat

And maybe some day I'll actually get around to starting to use the post tags, so people can easily see all the times I've needed a longassgermanword.

Currently, I wish there were a longassgermanword for:

When you request a quote or information or something on the web, so you give them your spam e-mail address, since you have no idea whether it's a company that's going to start sending you ads every day, but then an actual person e-mails you to start discussing the matter, so now it's fine that the real person has your real e-mail address, but you aren't about to tell some insurance or finance or something person that they should e-mail you at the other address, because that would just be weird.
