Envelope Inserting

Our envelope inserting service includes low cost high speed options for direct mail or business mailings, as well as intelligent inserting options for transactional mailings. We also have a team of hand-workers for mailings that cannot be automated.

Our service does not start or end with envelope inserting either, we offer the full range of mail fulfilment services including data, printing, and postage. Our envelope inserting services are available at our ISO 9001 accredited mailing houses in Bedford and Southampton.

Envelope enclosing by hand

We have a team of people that work on envelope inserting jobs not suitable for machines.

They work to ISO 9001 standards and provide an excellent option for:

  • Low volume jobs
  • Jobs using non-machinable envelopes
  • Mailings that are not uniform
  • Mailings that are 'bumpy‘ i.e. contain merchandise

We can handle jobs that need to be posted or palletised ready to be bulk shipped.
