About project:
Our client is a UK-based advertising company helping brands reach targeted audiences through outdoor and digital advertising solutions. As the business expanded, so did the need to reach new advertisers and decision-makers at scale. Their outreach process was entirely manual, inconsistent, and impossible to grow without adding headcount.
Prospecting was time-consuming, follow-up was fragmented, and there was no reliable system for turning cold contacts into qualified conversations. Growth had hit a ceiling.
Lumio built and deployed a fully automated prospecting and outreach infrastructure from the ground up. A targeted advertiser database, personalized email sequences, LinkedIn outreach workflows, and a fully integrated CRM pipeline replaced the manual process entirely, creating a predictable, scalable engine that ran without operational drag.
What we did:
Building the Database
We built a targeted database reaching over 300,000 advertisers and marketing decision-makers, segmented by industry, company size, and advertising spend profile. Rather than working a flat list, we prioritised outreach toward accounts showing active signals of budget availability and campaign activity, ensuring effort was concentrated where conversion was most likely.
Standing Up the Infrastructure
We built a dedicated sending infrastructure completely isolated from T4Media's primary domain. SPF, DKIM, and DMARC were enforced across every sending domain, with automated mailbox warmup running before a single email went out. Inbox rotation across the mailbox pool held placement above 90% and kept bounce rates under 2%, protecting our clients' brand domain throughout.
Launching Multi-Channel Outreach
Every prospect entered a coordinated sequence spanning email and LinkedIn. Over 25,000 emails went out with personalized openers referencing each prospect's specific industry and advertising context, achieving a 64% average open rate. LinkedIn connection requests ran in parallel, and follow-up touches delivered relevant proof points at timed intervals. Every sequence closed with a direct booking link, removing friction from the path to a conversation.
Tracking the Pipeline
Every email opened, reply received, and LinkedIn connection accepted was logged automatically into the CRM with no manual entry. With over 16,000 emails opened and a 290% increase in lead flow, Our client had full visibility into campaign performance in real time, with warm prospects surfaced and assigned the moment intent was signaled.
