Why do I need SendGrid integration with ExplaraBiz Email Marketing?

The email marketing tool in ExplaraBiz is useful to create beautiful, customizable templates; however, sending it to the contact list needs an email service provider such as AWS SES or SendGrid or Mandrill. 

If you wish to send emails in multiple of 1000s per day, it is always advisable to use AWS SES or Mandrill or Sendgrid.
