best tool for creating mass emails account?

it does't matter if is on yahoo, gmail, hotmail

I would love to know this as well, but from what I'm aware the decent ones will cost abit.

Yes, I would like any info on this as well. Specifically, which ones do the best job?

You woun't find a tool for creating mass gmail account. Th everification process makes it impossible. However you can use one gmail account several times. Hotmail yes. Do a search on this forum and you will find a couple. Yahoo, I wouldn't bother. Yahoo deletes auto created accounts faster than you can create them.
