Very interesting. This could be a simple low-tech alternative to Facebook groups and such, given that not everybody has a Facebook account.

Conversely not everyone has a Gmail account either. Do people who join a zeromailer mailing list need to sign up to Google to use the service? That would make it less useful.

No, anyone with an email address can be on a ZeroMailer list. For now, we're requiring a Google sign-in to create lists, in large part to curtail spam.

How does that curtail spam? It's not a lower barrier than a Captcha. Although it takes longer to set up a throwaway login, many spammers have lots of throwaway accounts on hand.

That sounds reasonable, thanks for the reply.

Nice idea, one thing I'd like to mention is you really should state somewhere that you're not storing people's contacts (I do hope that you're actually not), otherwise the perceived security of Google authentication drastically reduces. But overall great design, I hope it takes off!

Hi. ZeroMailer founder here - We're in fact not storing any contacts. We should make that more clear in the FAQ.

Been using Zeromailer for some random groups of friends and it's been super useful and easy to use. Lowers the barrier for communication significantly when you don't have to remember 10 emails or find an old email to copy paste the to: field from.

Long established alternative ran by a friend that doesn't have limits and doesn't require a Google account/sign-in either: http://www.freelists.org/

Really, really simple to use. 2000 emails a month will be plenty for me for right now.
