How a bank launched a new service with Callo

A regional financial services provider, that decided to stay anonymous, had just rolled out a new premium debit card with cashback and travel perks. They sent out thousands of emails to existing customers — but open rates were disappointing, and only a fraction of clients learned about the offer.

A faster way to spread the word

Instead of waiting for customers to «maybe read the email», the bank turned to Callo. The voice agent was loaded with a simple script to tell clients about the new card in a friendly, personal tone:
— Hi, this is [bankname]. We’re excited to let you know about our new premium debit card that gives you cashback on everyday purchases. Would you like to hear the details?
Customers could press 1 to connect to a manager, or press 2 to get more info by email/SMS.

The campaign results

In the first week of the campaign:

  • 15 000 clients contacted automatically
  • 4984 clients (30%) requested more info
  • 2571 signed up for the new card
  • Launch coverage achieved in days, not months

How spotting shifting customer sentiment helped

Apex bank, a mid-sized regional bank, had solid client retention. But leadership felt uneasy. Competitors were rolling out flashy mobile features, and rumors suggested younger clients were considering switching. The bank’s standard quarterly surveys didn’t reveal much — customers mostly ticked “satisfied” and left no comments.

When five stars aren’t enough

A hotel chain was getting plenty of star ratings, but no real explanation. Email surveys returned low reply rates and online reviews only showed extremes. The team needed detailed, on-the-record insights across locations — the kind of feedback you can act on — but traditional surveys weren’t cutting it.

Keep loosing members? Just ask why

FitZone Gym noticed a worrying trend: more and more members were canceling their subscriptions after just a few months. Exit surveys sent by email went mostly unanswered, and front desk staff rarely asked people leaving for their real reasons. The management team was left guessing — was it pricing, equipment, or maybe poor class scheduling? Without clear answers, they couldn’t stop the churn.

A clinic wanted honest feedback & stopped handing out paper forms

For years, BrightSmile Dental relied on paper surveys left at the reception desk. Most patients were in a hurry to leave, and only a handful bothered to fill them out. Even those who did were often polite rather than honest. The clinic had no real way to know what patients truly thought — or why some never booked a follow-up

How SproutBox validates new ideas in a day

When you sell meal kits, trends move fast. SproutBox’s marketing team had plenty of ideas—new recipes, bundle offers, a “family night” plan—but email polls took weeks and social votes were noisy. By the time answers arrived, the moment (and the budget) had moved on.

A robot that never says “I don’t know”

Fixit Garage never missed a call again

Fixit Garage was busy all day — repairing cars, handling paperwork, juggling customer questions. But the real problem started after 6 PM, when the phones went silent in the shop — but not for customers. Drivers stuck on the roadside or clients trying to book a morning appointment were left with voicemail. By the time staff called back the next day, many had already gone to a competitor.

NetLink kept customers calm during a sudden outage

NetLink, a regional internet provider, had built a loyal subscriber base — until unexpected outages started to cause trouble. Every time a server crashed, hundreds of clients picked up the phone at once. Lines were jammed, support agents scrambled, and the same “What’s going on?” question was answered again and again.

How a small bistro stopped missing orders — and started growing

Most callers wanted the same things — today’s menu, delivery time, and “extra sauce, please” — but with just two operators on duty, calls piled up fast. By the time someone picked up, some customers had already moved to competitors with faster response times.
