When you get an email that needs time consuming back-and-forth, just forward it to [email protected]: → “Schedule this week” → “Follow up next month and ask about the raise” → “If she doesn’t respond remind me next week” And Serif takes over as you until the task is done.

No more pretentiously “CC’ing in my EA” or chasing threads to make sure things get done. Simply forward threads to Serif and wake up to meetings scheduled, follow ups sent, and tasks completed. Best part? To the recipient, it looks like you sent every email yourself.

Handoff is only possible because of the comprehensive knowledge base Serif has on you. It knows your voice, your relationships, your schedule, even your priorities. Only with this context, can Serif take over as you. Without it, it’s just another generic agent.

Handoff is available today in research preview to everyone with a Serif assistant ( During the research preview, Handoff is constrained to three use cases that have been rigorously tested in production: scheduling, follow ups, and reminders.

If you’ve gotten this far, I have a small thank you gift. I've compiled a 10+ page playbook that includes the actual cold emails we sent to go from nothing to a waitlist of 10K in one month. Just retweet and comment “handoff” and I’ll send it to you for free.
