With the Access Logs feature, you can easily check who accessed your email accounts and when it happened exactly. Not only that - each Access Log provides you with a status, so you know if the connection was successful.
You can open it by navigating to any of your Hostinger Email Accounts and choosing Email Logs on the side menu:

Right on top, you will see an ability to choose which period would you like to analyze: last hour, last 24 hours, last 7 days, last 14 days, or even last 30 days.
As well as choose which email accounts to filter:

Below you will see these five sections:

Time - exact time your email account was accessed
Email account - email account in question
IP or hostname - who accessed your email account
Status - action status to see if it succeeded or not
Protocol - shows the protocol used (it will be either SMTP, IMAP, or POP3)
In case you see Status as an Incorrect password - we highly recommend double-checking your password and changing it if needed.
