# 404 Not Found using Sendgrid API

 * I have a ticket with sendgrid but wanted to see if Mailpoet was aware of this
   issue. Getting 404 Not Found error when clicking on a link in an email sent using
   Mailpoet 2.7. Tested it several times and depending on the email address like
   Gmail or AOL the link may or may not work. At first I thought it was related 
   to the tracking in Sendgrid so I deactivated all link tracking and the issue 
   still remains.
 * The link in the email template is a basic URL [http://www.domain.com](http://www.domain.com)
   but you can see that the link changes when in the received email. Somehow this
   is causing an error when opening the link in a browser window.
 * Anyone know what the cause could be? Do I need to consider another SMTP vendor?

 * I did another test! I created an account with Elastic Email as per your guidelines
   and sent the same email template using Elatic Email SMTP.
    The same issue is 
   still happening. So that can only mean that somehow your plugin when using a 
   thridparty SMTP is creating an error in the link causing the 404 Not Found.
 * Here is a response from Sendgrid when I sent them the link that was in the email
   after receiving it through their SMTP system.
