CEO approves first. Then show up at the venue
ServiceNow Knowledge attendee/speaker list, VP/Director only. Tier 1: CEO reviews and sends LinkedIn plus email. Tier 2: same-day AE LinkedIn. Tier 3: on-site iMessage. No send until the CEO approves. Do not spray volume after cold email fails — change context with event presence.
