Hi, 

I've configured the Day Email Server with my Gmail email, which works because I am receiving workflow emails via this Gmail account, so the configuration is correct. 

But I am trying to send a campaign email newsletter and the MessageGatewayService always comes back with null.

In my class I reference the service:

@Reference
    public static MessageGatewayService messageGatewayService;

And then want to retrieve it via:

MessageGateway messageGateway = messageGatewayService.getGateway(HtmlEmail.class);

I found that quite some people have had the same issue but I couldn't find any solutions. 

Anyone have an idea what is going wrong?

Any help is very appreciated!

Thanks, 

Alex
