This plugin is awesome! I love it!
I'm currently using it for a website that's still in development. Basically we send html mails out with information about a custom post. The subscriber filters the mail they want to receive by filling in their preferences (quite a lot of checkboxes). Subscription is double opt in and people can unsubscribe easily with just two clicks.
What I'm worried about, though, is whether the plugin will be able to cope with a large amount of email going through (large being, say, 200 emails in one go, but this only happens less than once a day).
I now call wp_mail with a foreach statement. Should I spread recipients in bcc headers? Or should I delay the foreach? Or will it just work fine now?
Thanks a lot!
