Mailgun was developed by teams operating under the RackSpace Corporations. It enables stress free email transfers to all entrepreneurs and developers worldwide. Mailgun not only provides email deliveries to prescribed customers, but also ensures the authenticity of the email addresses of the customers to which they are delivered. It also enables its users to create sectional compartments for the different domains that are to be added and thereby assures easy managing of personal and official mails. Mailgun offers an official login to WordPress as well.
