Why do you need this?

You need this to know what's happening with your emails. Similar to Google Analytics which you use, to analyse website traffic, you need this tool to analyse 'email traffic'. If you're not analyzing any email traffic, you're missing out. So whether it's a newsletter email, a transactional email such as a WooCommerce order email/new sign up, or an email relay to your Gmail inbox, it's important that you log this data so you can always troubleshoot/analyse this data. Every website need this, similar to Google Analytics. Try for free and see for yourself.

Will I have my own SMTP username and password?

Yes, after signing up, verifying your domain, your own SMTP username and password will be ready for you to use. All of your emails will be logged and easily viewed in your own email dashboard.
