At one point in time believe Paul had problems sending out the Daily'ish e-mail to many many people. Believe he was blacklisted from places and was given the tsk tsk tsk, should have known better attitude, when his e-mails were marked as spam/junk/trash/no good/whatever.
Sooo, I know someone who is developing an app to let consumers know (they subscribe to farm(s) and/or product(s)) when new item(s)are available at a specific farm stand.
The software is moving along fine, but the stumbling block they are having is finding a suitable e-mail service.
There are several companies providing a service where the company manages lists themselves and organizations create e-mails to send to the targeted lists. This won't do.
In this case the software actually needs to generate and send e-mails itself to the individuals. Is it simple as putting an address in the bottom (like the daily e-mail has now), or getting put on an exclusion list? The software could potentially generate several e-mails per person / per day depending on their subscriptions and how often notification should occur.
