These will be the first we've sent! We've been planning a single follow-up email a week or so after any event you attend highlighting coverage for a while now, so we're using SXSW as an excuse to build the feature.
Sounds great. A key section to this email could be showcasing the sessions I actually attend (which is often quite different than what I RSVP for!). Will there be any check-inesque functionality for sessions?
