I installed Magento 2 on Ubuntu/Apache/Sendmail and setup email configuration on Store -> Configuration -> Advanced System -> Mail Sending Settings & Sales -> Sales Email Settings.
I configured cron via cli too.
Now, whenever an action takes place (example: Newaccount creation, new order or etc), the system is not sending email.
Please help me.

If you are on live server you need to enable sending emails and if you are on local server then you can achieve it by installing some Magento 2 extensions which are working perfectly.
Some of the tested extensions for custom SMTP are listed below:

First you need to send testing mail if it will work then you can go further and if this will not work then you need to debug like store id and area etc do let me know if you are facing the issue.
