Across Your Portfolio, The Average Lead Waits 43 Hours For Your Client To Reply. MangoTeq Sentinel Cuts That to Under Five Minutes, On Every Account.
Researchers measured it across thousands of businesses. Your campaigns aren't the problem. The 43 hours after the click is.
Researchers at MIT and InsideSales.com measured lead response across thousands of businesses. A lead contacted within five minutes of enquiring is 21 times more likely to qualify than one contacted after 30 minutes.
The average service business — the kind your agency runs paid ads for — responds to new leads 43 hours after they arrive. That gap is where your clients' conversion rates go, and where your agency's retention problem begins.
MangoTeq Sentinel closes that gap automatically, without your clients changing anything they do.
Your agency isn't the reason the leads went cold. You can prove the campaign worked. You can't prove what happened after the lead arrived — because that data lives in your client's CRM, not yours.
A lead contacted within five minutes is 21 times more likely to qualify than one contacted after thirty. The average service business takes 43 hours.
That gap is what's costing your agency client retention, not your targeting.

The Problem
Why Agencies Absorb the Blame for a Problem They Didn't Cause
Your agency has complete visibility over everything it controls: campaign performance, cost per lead, landing page conversion, click-through rate. In most cases, that data tells a positive story.
What you cannot see is what happens after the lead arrives. Response time, follow-up frequency, contact channels — all of that exists in the client's CRM. Your data ends at the inbox.
So when a client's leads fail to convert, the conversation is predictable. You show campaign data. Everything is fine. The client hears "it wasn't us." Which is accurate, but accuracy isn't proof.
7:12 PM // Lead arrives via your client's campaign
Enquiry lands in the client's inbox
Nobody on the client's team is free to respond
7:14 PM // 2 minutes later
Prospect calls the next business on Google
Competitor answers on the first ring
7:19 PM // 7 minutes in
Job booked with a competitor
Your campaign generated the lead. Someone else got the job.
Month Four // The review call
Client says: "The leads aren't converting"
You show campaign data. They blame the ads anyway.
One System. It Answers Every Client Lead Within Minutes.
Sentinel is a fully managed lead response and follow-up service. It connects around your client's existing lead sources, CRM, and calendars, and responds to new enquiries within minutes.
The Solution
It Connects Around What Your Clients Already Use. MangoTeq Runs All of It.
It follows up across WhatsApp, SMS, voice, and email until the lead is booked, qualified, or opted out, and sends reminders after bookings to reduce no-shows. It records every contact, every conversation, and every outcome, so your agency can see exactly where every lead went. Your client doesn't manage it. Your agency doesn't manage it. MangoTeq runs all of it.
Sub-5-Minute ResponseEvery client enquiry hears back before the prospect dials the next business on Google
Full Lead VisibilityEvery contact attempt and outcome logged, so the "bad leads" objection has no purchase
Done For YouMangoTeq builds it and runs it. Nothing for your team or your client's team to manage
Automatic Follow-UpIf the first message gets no reply, Sentinel keeps following up across every channel
Sentinel works around your client's existing CRM, calendar, and lead sources. Nothing changes for your client's team, and your agency keeps the relationship at every stage.
How It Works
Three steps. No disruption to your clients.
1
We Diagnose
We review the client's current lead flow and show you exactly where response delays are costing booked revenue.
2
We Deploy
Sentinel is built around the client's existing CRM and calendar. No software for them to install, no process to change.
3
We Protect
Every enquiry gets an instant response. Your agency gets the data. The client's conversion improves.
The Outcome
What That 43-Hour Gap Costs Your Agency in Concrete Terms
Clients who churn from service agencies do so at a consistent point: months three to four. One client at £3,000 a month represents roughly £700 in profit after costs. Losing that client at month four removes £5,600 in future profit, from a problem the agency neither caused nor could see.
Ryan Unrau, a specialist in database reactivation, worked with a £40 million roofing company. 2,000 leads, three years old, written off entirely. Structured follow-up turned them into £48,000 in booked revenue. Same leads. Same prospects. The only thing that changed was follow-up.
Leads contacted and followed up properly, so client conversion improves
Full visibility into every lead, so the "bad leads" objection has no purchase
Results improving month over month, so clients increase ad spend instead of reviewing the agency
The month-four churn call doesn't happen when the client's numbers are improving
The 43-hour gap was never your campaign's fault. Now it's not your client's either.

"Most agencies we work with discover their churn isn't a campaign problem at all. It's how slowly their clients' leads get a reply. The campaigns were never the issue."

Questions Agencies Ask Before They Commit
Straight answers to what agency owners ask us most.
Account managers handle follow-up during business hours. The gap is everything outside those hours. Sentinel covers it, on every channel, without adding to anyone's workload.
The process is the same at one client or thirty: a short questionnaire, passed through your account manager, returned to us. We build it and run it. You receive a weekly report, or a live dashboard, across every account.
No. Every message is written in the client's own voice, before it goes live. The lead does not see MangoTeq.
A notification and a response are different things. The notification tells someone a lead arrived. The response is what Sentinel provides.
Worth checking before assuming it. A lead left too long looks exactly like a bad lead. The two are indistinguishable until someone actually replies.
Pricing and terms are agreed on the call, once we've reviewed that client's lead volume and pipeline. If we don't deliver the agreed minimum of qualified conversations within 60–90 days of go-live, we continue working at no additional cost until that threshold is met.
It depends on the client's lead volume and deal value, so we work it out on the call. Pricing is performance-aligned in most cases. We go through the numbers together before anything is agreed.
