Either you need to install https://github.com/mageplaza/magento-2-smtp or http://blog.techwheels.net/send-email-from-localhost-wamp-server-using-sendmail/

Hope it will help you.

You need to install one of the best-known extension for GMail SMTP from github and after installing that extension your site doesn't come to any errors.

https://github.com/magepal/magento2-gmail-smtp-app

let me know if you have any issue.

Hello @shweta_singh1

Seems like you installed the module into app folder, please remove from it, add module using composer 

Run below command from Magento root directory

composer require mageplaza/module-smtp

if you want to still install into app/code folder, then downlod core module from below link and install it

https://github.com/mageplaza/module-core

Hope it will help you.

If works then mark as a solution or give kudos.
