Email Logs and Sent History
We are storing a log of outgoing emails from our system with your SMTP status. Whether the email sent to the receiver, or failed to send, both will be recorded here along with if any SMTP error during the time of sending emails.
There is a clear button for the logs. You can clear them when you think its overloaded.
To view Email Logs and Sent History, goto Setup > E-Mail & SMTP > Email Log
