@bix I chose to know because I'm always testing and mucking about with things so didn't want to accidentally send half a dozen "test" emails to anyone who signed up. I may remove the ability to know in future and test against a non-live list but that will take a little more work.
@colinwalker What are you using to code the Daily Emails?
@MitchWagner It's all automated within WordPress. The Today template re-writes a value to the database each time it is loaded (to ensure it's current) of the content of all posts for the day. Then I have a separate page which takes that value, adds a little extra text and sends it to the subscriber list (again held in the database) - that page is loaded at 5 past midnight each day via a cron job. Entirely self designed and a lot simpler than I imagined it would be.
@colinwalker I'm going to want to look into that if I ever go back to Wordpress.
I use MailChimp to automatically compile a daily digest from RSS. Got about 40 subscribers. Who knows how many actually look at it?
