Often times when you’re dealing with WordPress and the way that it emails out, especially when you’re using things like Gravity forms and all that. Sometimes you just don’t get the notifications and you’re like, “What happened here? Did it not go out? Did it hit my spam? Did Gmail not like me? What’s going on here?”
This plugin is called WP Email Logs, and whenever you send any kind of email at any time, this plugin will store the details to a database table and then you can check out those logs. So the site admin can see a full list of every email that’s been sent out and you can really pinpoint if you’re having email problems as far as sends from your WordPress installation exactly what’s going on.
So it sends the From and To, user IDs, it logs the email address, the subject, the content, what type of email, the send, date, time — all that kind of stuff. So this is the most prolific plugin that I’ve seen regarding email handling within WordPress and I rated it a perfect 10.
