Hi,

We have a custom output slack plugin which post some alert messages to a slack channel. I would like to prefix the alert message with a "@userid" so that the slack sends an email to the user that he is mentioned in the post. But as of now, if I prefix it with, say "@bharath_meka" , it is not resolving at the slack end as a "mention" but is posted as a static text.

Is there something to do at slack end or can I handle this in my plugin?

Regards,  
Bharath

I suppose you'll have to adhere to the [Slack API's conventions for linking to users](https://api.slack.com/docs/formatting#linking_to_channels_and_users), i.e. say something like `<@6AF9884E8|some-user>` instead of `@some-user`.
