Dead Leads, Live Pipeline: How an AI Agent Reactivated 3,000+ Lost DHL Leads
DHL Express Singapore had a pool of lost, inactive and non-responsive leads sitting untouched — and a sales team already stretched thin running an unsustainable mix of calls, voicemails and emails. Rather than hire more reps, DHL partnered with SalesboxAI to build an AI Avatar that could re-engage every contact, consistently and persistently, at scale.
The company
DHL Express is a division of Deutsche Post DHL, the world's largest logistics company, providing international courier, parcel and express mail services. Across DHL Express, DHL Parcel, DHL eCommerce, DHL Global Forwarding and Supply Chain, the group employs more than 350,000 people and operates in over 220 countries and territories. For this programme, DHL Express Singapore partnered with SalesboxAI to re-engage its lost, inactive and non-responsive lead base — without expanding its sales team.
The challenge: too many dead leads, not enough hands
- Thousands of lost and inactive leads sat untouched — too large for reps to work manually with any consistency.
- DHL's existing playbook asked every rep to make multiple calls, leave voicemails and send multiple differently-worded emails per lead — impractical to implement and manage, and too time-consuming to sustain.
- DHL had already tried predictive analytics and email automation tools with underwhelming lift, and wanted proof before committing further.
- The mandate was to re-engage every contact without hiring additional sales reps.
The solution: an always-on teammate, not another tool
SalesboxAI answered with an AI Avatar built specifically for DHL Singapore — Amy Leung — designed to do what no rep roster could sustain: persistent, personalized, always-on engagement across thousands of dormant leads.
A dedicated AI Avatar
Created 'Amy Leung', an AI Avatar with unlimited bandwidth, giving DHL a tireless, always-on presence across its entire lost and inactive lead base.
A 9-step email cadence
Amy engaged every lead with a series of 9 scheduled email messages, set to specific dates and time frames, gauging attention and consistently staying top of mind.
Persistent, human-feeling outreach
Amy proactively asked leads simple, direct questions about why they'd stopped using DHL — outreach DHL's own sales team came to see as another reliable team member's work.
Seamless human handoff
The moment a lead responded and re-engaged, Amy introduced DHL's sales rep at exactly the right moment — turning a warmed-up conversation into a live sales opportunity.
How it ran
- 1Agreed a 90-day 'Pilot Project Campaign' as a low-cost, low-risk way to test the approach.
- 2Built 'Amy Leung', an AI Avatar with unlimited bandwidth, specifically for DHL Singapore.
- 3Set up a 9-email cadence per lead, scheduled to specific dates and time frames.
- 4Ran the cadence continuously across DHL's lost and inactive lead base for three months.
- 5Surfaced hot leads out of the dead-lead pool as soon as a contact responded.
- 6Introduced DHL's sales rep the moment a lead re-engaged, converting warm conversations into opportunities.
The results
"DHL has experimented with predictive analytics tools and other email automation tools. But frankly, the amount of lift we got from all of those technologies combined was not as great as we are getting from SalesboxAI."
"Thank you very much, Amy, for contacting me. Yes, I want to be associated with DHL for all my Logistics needs."
Why it worked
Re-engaging a dead lead usually means picking up where a rep left off — except reps don't have unlimited bandwidth, and dead leads don't wait. Amy did what no headcount increase could: showed up consistently, asked a simple human question, and stepped aside for a real sales rep the moment someone said yes.
