Sorting the test address list

Once you have downloaded the Mailsort/International Bulk Mail or Walksort/International Bulk Mail Test Address List, you must use your software to sort this list according to one of the following schemes and generate a printable report and electronic file of the Computer Planning Report, Line Listing and the sorted Test Address List for submission to the Mailsort Technical Department for validation.

Please note - you must use the appropriate version of the Mailsort/Walksort database - see the download page for details.

Mailsort Mailing Schemes Walksort Mailing Schemes
Mailsort 1400
Mailsort 700
Mailsort 120
Mailsort 1400 Mixed Weight
Walksort
Walksort Mixed Weight

There is no specific Presstream scheme as, for sortation purposes, there is no distinction between Presstream and Mailsort 1400.

International Bulk Mail may be added to anyone of the above services, or alternatively it may be used purely for an international mailing.

If you plan to submit tests for more than one Mailsort mailing scheme then in the first instance please submit test results for one scheme only - choosing the scheme nearest the top of the above list.

For example, if you plan to send Mailsort 1400, 700 and 120 tests, then in the first instance send in the Mailsort 1400 test only; or if you plan to send Mailsort 1400 standard and mixed weight tests then please send the Mailsort 1400 standard test first.

Epro File

For International Bulk Mail test, as well as submitting the line listing and planning report, please submit an Epro file for testing.

The Epro file must be of a fixed length, all specification details can be found in the International Bulk Mail User Guide, available from the Downloads, Mailsort User Guide section of this website.

International Destination Sort

For details regarding this service, please see the International Destination Sort User Guide, available from the Downloads, Mailsort User Guide section of this website.

Once you have successfully completed the initial test you may submit tests for other schemes, in the above sequence.

Test Parameters

  • Sort each scheme (apart from the Mixed Weight varieties) as 45g letters.
  • Please use the maximum bag weight of 11000g.
  • Although your software may permit user choice of minimum selection size for Mailsort 1400 and 700, please use the standard minimum selection size for letters of 25 items for the tests. For Mailsort 120, the minimum selection size should always be 1.

  • PiP Mixed Weight Schemes

    The Test Address List contains a Weight Indicator for each item. You should use this indicator to determine the item weight for mixed weight schemes as follows:

    Weight IndicatorWeight
    Mailsort 1400
    (Large Letters / A3 Packets)
    Mailsort 1400 (Packets)Walksort
    (Large Letters / A3 Packets)
    148g*48g*48g
    270g70g69g
    3130g150g97g
    4212g220g187g
    5550g700g300g

    *If you plan to submit test for Mailsort 1400 Undersized Directs Mixed Weight schemes, please use item weight of 60g for Weight Indicator 1.

    For furhter details regarding to this, please see the Pricing in Proportion (PiP) Mailsort User Guide, available from the Downloads, Mailsort User Guide section of this website.

    Other Considerations

    The Software Testing Process is designed in part to determine whether or not software is able to allocate correctly selection codes from Postcodes (Mailsort and Walksort) and Post Towns (Mailsort only) in addresses where quality and format of addressing may vary. Therefore, if your software provides address cleaning and Postcoding functions in addition to sortation for Mailsort or Walksort, these additional functions must be disabled for the purposes of the software tests.
