Can MailChannels send webhook notifications to Slack?

At this time, webhook notifications cannot be sent from MailChannels to Slack. 

Slack requires the JSON payload to be sent in a specific format that is incompatible with the MailChannels format. As such, any requests to post to Slack gets rejected. 

A workaround is to use Zapier to consume the webhook and send a message to Slack.
