I'm building a website that allows users to post comments. When they do, they can check a box that indicates if they want an email notification when someone else posts a comment under the same topic. (Similar to this web site.)This means when a comment is posted, the code has to send an email to all the subscribed users.My concern is about what happens when many users are subscribed to a topic. There is a short delay when sending an email. Sending dozens or potentially even hundreds could really cause a delay.Right now, I just loop through each user and send the emails one by one. Does anyone know if that's the best way?Thanks!
