title: How to subscribe to Amazon SNS topic with e-mail endpoint via e-mail?
body: <p>I'm using Amazon SNS to send simple messages to users. I'm using several topic with different endpoints including E-Mail.</p>
  
  <p>Right now subscribtion to topics is handled by the Java back-end via AWS Java SDK. I get user's address and create a subscription via <code>AmazonSNSClient</code>. The user has to confirm his subscription. Later or he can unsubscribe just by clicking a link in the mail sent my Amazon SNS.</p>
  
  <p><strong>What I was wondering - isn't is possible to let users subscribe via e-mail?</strong><br>
  Like sending an e-mail to <code>subscribe@....amazonaws.com</code> with the ARN of the topic as subject - or similar?</p>
  
  <p>I could then just display a <code>mailto:</code> link as a subscription link in my application which has a few advantages in my case.</p>
