37 days to go from $0 to $100 million

How Mailbox Became a $100 Million Acquisition in Just 37 Days

In January 2013, Gentry Underwood launched Mailbox, a revolutionary email app designed to tackle a problem many of us face: an overwhelming number of unread emails. In just 37 days, Mailbox went from being an unknown startup to being acquired by Dropbox for an estimated $100 million.

How did this happen? The Mailbox team executed a brilliant strategy that combined a clear problem-solving approach, viral marketing, and innovative user acquisition tactics.


The Problem: Email Overload

At the time, email inboxes were chaotic and overwhelming for most users. Despite many email apps on the market, none provided a simple, effective solution for managing unread messages.

Mailbox’s Solution:
They introduced an elegant feature set that allowed users to:

  1. Swipe to archive or delete emails.
  2. Snooze emails for later, keeping the inbox clean without losing track of important messages.

The app’s simple, intuitive design immediately stood out in a crowded market.


The Strategy: Build Anticipation with the “Referral Reservation System”

To generate buzz and exclusivity around the launch, Mailbox implemented a referral-based reservation system that was both automated and gamified:

  1. Users Signed Up for Notifications: Interested users registered to receive an alert when the app became available to them.
  2. A Queue Displayed Progress: Users could see their position in the queue and how many people were ahead of them.
  3. Encouraged Friend Referrals: The system incentivized users to invite friends. The more friends they referred, the faster they moved up the queue to gain access to the app.

This system created a sense of urgency, exclusivity, and viral growth as users competed to get early access.


The Viral Catalyst: A Video That Captured the Problem

Mailbox produced a simple, elegant video showcasing the problem of email overload and their beautiful solution. The video resonated deeply with viewers because:

  • The problem was urgent and relatable.
  • The solution was clean, innovative, and easy to understand.

The video quickly went viral, spreading like wildfire across social media and among tech enthusiasts. You can watch it here.

The buzz generated by the press further amplified the viral growth already fueled by the referral reservation system.
