Address cleaning

Successful mailings begin with quality mailing lists.

Asendia offers a host of international and domestic data processing services to help our customers maintain the quality of their mailing lists, reducing waste and costs, and improving delivery times and response rates.




Quality personalisation and print management.

Whether you’re mailing direct mail, business mail, or publications, you need your addressing and messaging to be clear and formatted appropriately for the postal system. Asendia provides you with both laser printing and inkjet personalisation options. Our pre-press services can set up both simple mail merges or complex requirements using data and images from your database.

Additionally we get trade rates for digital printing and litho printing, so why not see if our print management service could help you save money.




Some very well-known publications are polywrapped and mailed by Asendia.

With high-speed Sitma packaging systems, we can polywrap almost any mailing, from large catalogue runs to niche magazines. Jobs range from 500 magazines to 500,000 catalogues.

Hand packing

Not every mailing can be automated, especially if you have something really creative in mind.

That's why we have a team of handworkers who can quickly fulfill all manner of mailings. Over the years we've handled lots of mailings that are unusually shaped, are going in a carton or jiffy bag, or need hand finishing.

We really know post! Our parent companies are La Poste and Swiss Post, and we work very closely with Royal Mail and other domestic postal partners in 200 countries.

We will process your mailing lists and sort your mail to maximise postage discounts, whether using our postal solution or your own account with Royal Mail etc.

Once ready, your UK mail is collected, and international mail is exported from our distribution centre at Heathrow, imported into each country and handed over to the local postal service for final mail delivery.



How could you benefit?

Asendia gives you peace of mind that your mailings will run to schedule and budget, providing deeply discounted postage and help you meet your environmental goals.
