Background
The Indianapolis Colts, known as the Colts, protect their blue-and-white brand everywhere it shows up. Founded in 1953 and now one of the NFL's most recognized franchises, the Colts had a branded email signature in place, but keeping it current depended on every employee updating it themselves. Adoption was mixed: some staff added the latest campaign banner or logo, while others didn't.
When the team's IT department began migrating its email system from on-premises Exchange to Microsoft 365, they needed a way to apply email signatures across both platforms at once, without pausing brand consistency until the migration finished.
Before & after
Before
Manual email signature updates left to individual employees
Inconsistent adoption of new logos and campaign banners
No way to target banners to specific departments
A hybrid Exchange-to-Microsoft 365 migration with no unified way to manage email signatures across both
After
Centralized email signature deployment across the whole organization
Consistent, branded signatures on every employee's email
Dedicated campaign banners for departments like Mascot and Ticket Sales
One email signature setup running across the hybrid environment throughout the migration
The Colts' challenge
The Colts needed every email signature to be uniform and on-brand across the organization, without relying on individual staff to apply updates correctly.
No way to enforce compliance: IT could ask employees to update their own email signatures, but had no way to guarantee they would, or catch it when they didn't.
A hybrid IT environment mid-migration: The Colts were partway through moving from on-premises Exchange to Microsoft 365, so any email signature solution needed to work across both systems at once.
Limited campaign flexibility: Departments like Mascot and Ticket Sales had no way to run their own dedicated banner campaigns.
The results
100%
email signature uniformity across the organization
Zero
manual updates needed after rollout
100%
brand coverage maintained through the entire migration
How Exclaimer helped
Exclaimer's support team worked directly with the Colts through remote sessions to deploy email signatures across their hybrid environment, so consistent branding didn't have to wait for the migration to finish. Exclaimer's design team also rebuilt the Colts' existing signature templates from scratch, matching the originals.
The Colts tested the new setup with a small group of IT staff first. Once that proof of concept held up, management gave the go-ahead to roll it out company-wide.
With Exclaimer, the Colts can:
Enforce email signature uniformity automatically, without relying on individual employees to apply updates.
Deploy email signatures across a hybrid environment, covering both Microsoft 365 and on-premises Exchange during the migration.
Run dedicated campaign banners by department, giving teams like Mascot and Ticket Sales their own branded content.
Rely on Exclaimer's design team to replicate existing email signature designs exactly, with no need to rebuild templates in-house.
