How to "Test" your campaigns are working as expected

Hi there! 

I generally test campaigns entirely within Customer.io. Methods that I find helpful include:

• Having a test segment setup for segment driven campaigns that contains only my testing profiles. Or manually sending (and resending) in events for event driven campaigns so that I don’t have to continually ask engineering to fire events from the backend. 
• Adding time delays into my workflows. They’ll show when a person hits the delay (you can see how many people are waiting in the delay), so I can ensure that profiles are taking the expected path as they progress. Delays are easy to delete/update before the campaign goes live.
• I also personally like putting in Slack notifications along the way. I just pipe them to my private channel with liquid attributes and copy to explain why I’m getting the notification. If it’s a rather low volume campaign, I might even leave those live in the campaign so I can keep tabs on the first live profiles that take the journey.
• Keeping messages in draft (except for those Slack notys 😉) is also super helpful while you test. That way I can see exactly what a profile would have/is about to get sent before it hits their inbox or mobile device. Once I’m happy, I can set the messages to send automatically in the future, send off any existing drafts, or delete them if they were really just tests.
