About Chain of Events
Chain of Events runs large international events and uses outbound to reach sponsors and commercial partners.

The challenge
Event sponsorship outreach operates against a hard deadline
Every lost week reduces the time available to reach sponsors, start conversations, and close commercial partnerships before an event.
Chain of Events needed enough outbound scale to contact thousands of potential partners without relying on a small sales team to send every message manually.
The solution
High-volume outreach during short sales windows
Mailscale gave the team the sending capacity to run sponsor outreach across audiences of 10,000-15,000 people, helping reach relevant decision-makers while there was still time to move interested sponsors through the sales process.
A note on the result: This story focuses on direct customer-reported campaign reply rates across audiences of roughly 10,000-15,000 contacts.
The results
Reply rates reached 1.2%-2% at scale
Across audiences of 10,000-15,000 prospects, campaigns produced reply rates ranging from 1.2% to 2%. At that scale, a 2% reply rate can create hundreds of conversations from a single campaign.
“A 1.2%, 1.5%, 2% reply rate across 10,000 to 15,000 people, that is good.
“The reply rate, that one is good. Nothing to add to this.
Why this matters
Meaningful scale within a limited selling window
Mailscale helped Chain of Events combine campaign scale with reply rates the customer considered strong, giving the sales team more sponsor conversations while time still mattered.
“The reply rate, that one is good. Nothing to add to this.
