Whistl and JICMAIL: From Industry Founding Member to Platinum Accreditation

As champions of the mail channel we're always looking at the ways we use data to make campaigns more effective.

Whistl has been at the forefront of helping clients understand, measure and improve the effectiveness of advertising mail for decades. Through our involvement with JICMAIL, the industry's audience measurement standard for mail, we have helped businesses use data-driven insights to plan, optimise and evaluate their campaigns.

So we are delighted to announce both Whistl Mail and Whistl Doordrop Media ​​​​​​have achieved JICMAIL Platinum Partner accreditation, recognising our expertise in applying JICMAIL data across planning, sales, customer engagement and campaign measurement.

What is JICMAIL?

JICMAIL (Joint Industry Committee for Mail) provides industry-standard audience measurement data for:

• Direct Mail 
• Partially Addressed Mail 
• Doordrop Media 
• Business Mail

As an organisation JICMAIL delivers the same type of audience metrics available across major media channels, allowing marketers to measure reach, engagement, frequency and campaign performance.

Advertising mail remains one of the UK's most effective marketing channels and JICMAIL provides independent data to support media planning and investment decisions.

Whistl Role in the Launch of JICMAIL

Whistl was one of the organisations supporting the launch of JICMAIL in 2018.

The initiative brought together major industry bodies and mail operators to establish the UK's first independent measurement currency for mail, providing advertisers with a consistent way to compare mail against other media channels.

The launch demonstrated the industry's commitment to making mail a fully accountable marketing channel, supported by robust audience data and research.
