Not receiving mails on my Zohomail account

Not receiving mails on my Zohomail account

My website is made on WordPress and I use the Contact Form 7 plugin to create the contact form on the contact page.

Whenever someone sends an inquiry the form submits successfully but I do not receive any emails,
I have done all the necessary setting, Everything looks good from my Zohomail account,
I installed Easy Wp SMTP , 
This is the error msg i keep on getting 
  SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

Is  there any setting that i  am missing?
