In my project, when a user creates an account they get the mail. But after making an order neither the customer nor the admin gets the mail. I found many solutions but that's all for Magento 1.9 or below. I am using Magento 2. I need a solution with or without using cron job. Can anyone help?
You might not able to send any email from local, because you have not configure SMTP on local server (Wamp/Xampp). You can used below free extension & input your gmail smtp details.
This will resolve your problem.
