Since we work in cooperation with Deutsche Post and its DIALOGPOST product, there is a minimum volume of recipients for the mailing. With optilyz, you can send mailings throughout Germany and Europe with a minimum of 500 recipients, but there may be differences in some countries. In France, for example, the minimum volume is 1,000 recipients.

Please read this article to learn more about formats and shipping to our core markets.

Interesting for you: There is a lower postage threshold for mailings within Germany starting at 5,000 recipients. Then the postage per recipient drops drastically.

Calculation examples:

(A4 in envelope)
(DIN Lang without envelope)
(DIN Lang / Maxi)
< 5,000 recipients0,47 € / recipient0,43 € / recipient 0,47 € / recipient
> 5,000 recipients0,32 € / recipient 0,28 € / recipient 0,32 € / recipient 

You see: This might be profitable!

In general our customers send between 20,000 and 30,000 mailings for individual send-outs, and 5,000 mailings for automations. 

Basically, the higher the volume, the lower the costs per mailing and the more accurate the results of your campaign. This makes it easier for you to evaluate how well your use case performed and to adjust and expand your direct mail activities based on your results.

Warning on Noto Emoji 14.0 Important: In some countries, e.g. Germany, it is possible to include several use cases in one mailing, making it easier to reach a number of recipients of more than 5,000. Some things have to be taken into account, e.g. format consistency, same personalization elements, etc.
Attention: In Austria, this is not allowed - here, the content must be completely identical in relation to the use cases. Designs may differ, but the focus must remain on the same target group, i.e. texts must not differ too much from each other.
