About Synertec

Synertec provides reliable and cost-effective solutions for Complete Document Control.

A mutually beneficial relationship

Synertec and Whistl have worked together since 2009 with operational efficiency and loyalty at the heart of a successful relationship that’s seen over 1 billion mail items collected.

In recognition of excellent service, Synertec handed Whistl their Supplier Appreciation Award as part of the company’s 25th anniversary celebrations.

Handling huge volumes

Whistl and Synertec have worked together on many campaigns. The most significant of all included the mailing of 1st Covid-19 vaccination appointments in 2021. This involved over 60 million letters being sent, and on occasion over 1 million items were handled daily with only 2 days' notice.

Reliability is critical

90% of Synertec’s volume is health mailings, including high-priority NHS appointment letters. Whistl understands the critical nature of these essential items and always strives to provide high service levels, as evidenced by a 96.8% day 1 handover to Royal Mail.
