A couple of notes on new developments:

After waiting entirely too long for one company to get their act together on payment processing, we just decided to ditch them and go elsewhere. Within 24 hours, the paid plan was live. All current subscribers received an e-mail outlining the differences between paid and free, and we’re extending [...]

Some folks may have noticed that Mailmanagr is now offering a paid option.  Well, sort of.  Mailmanagr is trying to offer a paid option, but we’re still waiting on final setup from our payment processor.  Here’s the low-down:

We’re happy to [...]

We’ve put in an attachment limit of 25 MB at the server for file attachments (that means that if you send a message with a larger than 25 MB attachment, the [...]

37signals supports OpenID, now we do too.  If you’d rather use OpenID for your Mailmanagr account, rather than a username and password, you now have the option.  We’ve tested this out with quite a few publicly available providers, but if you run into trouble with your OpenID, please get in touch.
