Mail Opt Out, Opt In and Mail Returns

Mail Opt Out and Mail Returns Services

As a responsible organisation we want to make it easy for mailing recipients to opt in or out of mailing databases. We know that your organisation will probably want the same. This is why Sharp Cat is the first Mailing House in the UK to have a dedicated mail opt out and mail returns service. The service is available to all clients to utilise free of charge. enables business people and mail consumers to easily communicate their mail preferences.

Registering with the Sharp Cat Mail Opt Out scheme is one of the single most effective measures that individuals on a database can take to make their mail opt out preferences. This free mail service enables addressees to unsubscribe from the database used to mail them.

Using the mail code printed on the envelope each individual has the choice to opt out from all data lists held by a company or just one that is specific to a type of mail.  Any future mailings carried out by Sharp Cat exclude these addresses.  The opt out takes around 2 weeks before it is fully effective and each addressee remains on the mail opt out list until they opt back in.

Mail Returns Management

All returned mail arriving at Sharp Cat is physically counted and logged. Clients then have the choice of having mail returns data captured for free each month. Data captures includes the reason for return. The data captured is available to clients via secure encryption. The data is also used as a mail opt out suppression file against next mailings.

  • Address Incomplete
  • No Such Address
  • Deceased
  • Mail Opt Out Request - GDPR
  • Address Inaccessible
  • Gone Away

Would you like your postal returns data captured?

If yes – capture is free of charge and you will be supplied with a CSV file so that your central database can be updated.

A Gone Away Gateway Suppression file will also be created. This holds all your returns data so that any future mailings can be checked against it. This file is both encrypted and secure. Benefits of this service include:

  • Postage and material cost savings because gone away records will not be mailed
  • A suppression buffer, giving you time to update your own CRM
  • Retention of a good company reputation
  • Office space that is free from the clutter of returned post waiting for attention
  • Compliance with one part of GDPR
  • Higher postage discounts as % verified levels will rise

A point to note, mailing without permission to anyone registered on a mailing preference service or mail opt out is not data compliant and risks a fine. This is especially important with the tightening of data protection via GDPR.

It’s in every organisations interest to have an effective mail opt out solution plus returns handling. Databases that register Mail Opt Outs increase the per unit value of the recipients left. With the right data processes companies can expect to see more tightly focused mailing that delivers results.
