Blue Donkey cover

About Blue Donkey

Blue Donkey is a UK telemarketing agency that works only on outbound business-to-business calling. Rather than following scripts in a call-centre style, its callers hold unscripted conversations on behalf of client brands, with the aim of opening new sales opportunities and finding qualified buyers.

What Blue Donkey does

  • B2B telemarketing: outbound calling campaigns run in the client's name, built around informed conversation instead of a fixed script.
  • Lead generation: prospecting calls that identify and qualify potential buyers so sales teams can follow up.
  • Customer service calling: telephone contact with existing customers for corporate organisations.
  • Reporting and MI: detailed, customised campaign reports and management information for each client.
  • Data and databases: work on the contact data that campaigns depend on.

Who it works with

The agency serves corporate organisations and large B2B brands, and says some of its clients have stayed with it for around 25 years. It stresses long-term relationships over one-off transactions.
