Under construction; many more email samples coming soon.
I worked with the Dropbox Basic PMM to redo 30+ onboarding emails to raise product education and increase user activity. This is one example (of many).
Every year, Atlassian runs at least one April Fool's campaign. In 2013, it was JIRA Jr. — bug tracking software for your children. The video was produced before I came onboard, but I was in charge of creating a followup email for people who'd requested swag that stayed in the voice and tone of the original campaign, even though it was two months after the fact.
