Simon Chiu @geetfun.com · Dec 1 Building in public... Saturday evening edition. Creating the feature to rate limit outbound emails for sendbroadcast.com. Added a nice little UI here to let users know that their list might require multiple email servers, especially if they set a rate limit too low.

nice - how would this work for daily newsletters - 450k subs, three drops a day - good fit or not so much?
Wait is postmark rate limited to 50 an hour? That seems inconvenient for sending newsletters
For large lists, generally you need to be careful not to blast a whole bunch of emails at once. Otherwise the algo at the larger email providers (eg. Gmail, etc) will probably flag your domain as spam.
