ITV is successfully navigating the changing landscape of television through creating and distributing high-quality content via the largest family of commercial channels in the UK and on-demand via its ITV Hub.

Authenticating communications to give viewers confidence in ITV’s digital services

As a modern broadcaster, ITV has gradually increased its digital presence over the past decade to the point where it now has multiple points of email interaction with viewers, sending over 15 million emails in just 90 days, for example. Emails could be to confirm login details for a viewer’s ITV Hub account, acknowledge competition entries or for ITV Hub subscribers, making sure payment details are securely taken and processed.

Robust email authentication security needed

ITV needed to have robust email authentication security in place so both viewers and employees could rest assured that when an email said it came from ITV, it truly did. ITV quickly identified that OnDMARC could help them achieve this by protecting all their domains against impersonation.

  1. Insight into where to start

    When Business Analyst Grant Currie set out to tackle ITV’s DMARC project with OnDMARC the hardest part was knowing where to start. Initial estimates put the number of subdomains ITV owned at somewhere between 800 and 1,000, due to a mixture of parked domains, production houses and regional instances. With OnDMARC’s guidance, 1018 domains are now in reject.

  2. Building a futureproof email architecture

    Once implementation was underway a unique OnDMARC feature, Dynamic SPF, quickly came to the fore. Enabling Grant and the team to get on with configuration changes without coding Dynamic SPF not only sped up configuration but enabled them to overcome the 10 SPF lookup limit that plagues traditional solutions.

  3. Pathfinding with APIs

    OnDMARC’s Open API meant ITV could integrate with existing business systems. After pulling the stats for 1,000+ domains into Google Sheets, insight revealed that traffic only flowed to 200 of those domains. “We could start with the lower hanging fruit and work our way up to the bigger, more complex domains finishing on itself,” said Grant, ITV’s Business Analyst.
