Built for Ad & Social Media Agencies

The Reason Your Clients' Leads
Aren't Converting
Has Nothing To Do
With Your Ads

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.

InsideSales.com and MIT studied lead response across thousands of businesses. The finding was simple: speed of response, not lead quality, is what separates a booked job from a lost one.

The average SME service business — the kind your agency runs paid ads for — contacts new leads 43 hours after they enquire. Your data ends at the inbox. You can prove the campaign worked. You can't prove what happened after the lead arrived.

So when conversion underperforms, your client hears "it wasn't us." Which is accurate. But accuracy isn't proof.

Your agency isn't bad at its job. The campaigns are performing. The leads are genuine.

The gap sits entirely between the click and the callback — in the 43 hours most service businesses take to respond, while a lead that's contacted within five minutes is 21 times more likely to qualify than one contacted after thirty.

Your client blames the ads. The ads were never the problem.

The Problem

Why Your Agency Takes the Blame for a Problem It Didn't Cause

You have complete visibility over everything you control: the campaign, the creative, the targeting, the cost per lead, the landing page conversion rate.

You have zero visibility over what happens after the lead arrives. Response time, follow-up frequency, contact channel — all of that lives in your 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.

Sentinel Closes the Gap. Automatically. Without Your Client Changing Anything.

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

Every Lead Tracked, Every Outcome Visible. 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. Every contact and every outcome is recorded, 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 Response Every client enquiry hears back before the prospect dials the next business on Google
Full Lead Visibility Every contact attempt and outcome logged, so the "bad leads" objection has no purchase
Done For You MangoTeq builds it and runs it. Nothing for your team or your client's team to manage
Automatic Follow-Up If 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

How Sentinel Protects Your Agency's Revenue

The benefit goes beyond better client outcomes. The measurable benefit is retention: when leads are followed up properly and the client can see exactly what happened to each one, the "bad leads" conversation stops happening.

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

Your agency didn't create the gap. You're the one who closes it now.

Questions Agencies Ask Before They Commit

Straight answers to what agency owners ask us most.

Account managers do real work during business hours. The 43-hour average isn't built in the hours they're covering. It's built in the hours nobody is. Sentinel responds within minutes, on every channel, around the clock, without adding to anyone's workload.
The process doesn't change whether it's one client or thirty. One short questionnaire per client, passed through your account manager, handled entirely by us from there. You get a weekly report, or a live dashboard, across every active account. Nothing added to your team's workload.
No. Every message goes out in your client's name, written the way that business actually talks. The lead never sees MangoTeq. Not once.
A notification tells someone a lead arrived. It doesn't contact the lead, follow it up, or keep going until it books or opts out. That's the part most CRMs leave to whoever happens to be free, and it's the part Sentinel operates instead.
That's worth checking before assuming it's true. Ryan Unrau proved the point with a £40 million roofing company: 2,000 leads written off as dead, £48,000 booked once someone actually followed up. Same leads. The only thing that changed was follow-up.
Pricing and terms are agreed on the call, after we've reviewed that client's lead volume and pipeline. And if we don't deliver the agreed minimum of qualified conversations within 60–90 days of go-live... we keep working. No extra cost. Until we do.
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.
