I think Sanebox deserves it's own thread. I've mentioned using unenroll.me and Sanebox services to filter through my emails. I have an old yahoo email account that I just did not want to part with despite getting tons of emails from subscriptions I've enrolled in over the years. I still want the emails so that why I couldn't unsubscribe or create a new email account.

I tried Unenroll.Me which is a completely free service. Sanebox is the paid version but is so worth it. Sanebox works with Yahoo, Gmail and other email providers.

Cost is $4 a month for the cheapest plan if you buy 2 years at a time. Otherwise it's $5-7 a month.

Oh, they offer a free 2 week trial. If you get too many emails or just have trouble getting through your mail, but don't want to lose the emails you get, you should try it!!

Here's a review of it.
