LETTERS & COMBINATIONS

Letters are the best choice for building trust. Since they are less promotional and are sent in an envelope, the open rate is particularly high here. 


From numerous applications, we know that DIN A4 and a grammage of 90g is the optimal choice for advertising mail. Lower grammage becomes "translucent" and higher grammage, while more valuable, significantly increases costs.

COMBINATION WITH FLYER AS SUPPLEMENT

Combine your sales letter with eye-catching flyers as a supplement. For example, you can add attractive product suggestions to your cover letter. Flyers behave in a similar way to postcards, but are not addressed and are therefore considered as inserts in the envelope. These can be personalized - which of course increases costs and should only be used if personalization on the letter is inadequate.


You can add different types of flyers, but in Germany only DIN Lang flyers make sense. Because these use a DIN Lang shipping envelope ideal. Abroad, DIN A5 is often used.


Formats
 
 
DIN A6
DIN A5

The optimal grammages for flyer supplements are 135g or 170g.

ENVELOPES
Envelopes are used for letters and complex mailings with multiple components. But they are also used very often to send postcards that look less like advertising at first glance. If you choose an envelope without a window, it must be personalized. In most cases, however, a window is used.


The most common envelope format is DIN Lang dar. DIN C5 and DIN C4 are also possible, but make sense only in special cases (since the postage cost increases).

SELF MAILERS
Self-mailers give you maximum space for your advertising message. Use this format to give customers up to 10 pages of exciting insights into your products. Complete your self-mailers with response elements such as perforated coupon cards to 

give additional purchase incentives. With optilyz you send your self-mailers and mini-catalogs optimized for postage.


Attention: A selfmailer can be a very complex product with many layout requirements to follow. That is why such requests should be always consulted with your customer success manager first.

A tangible example for its complexity: a fashion customer used a self-mailer with a printed “flap” equally matching the graphic underneath on the front - in this case the customer’s graphics team has to make sure to include 2mm (because of the selfmailer's width) more content of the graphic on the flap to match the overlap exacetly to the graphic below.


This format makes sense especially for slightly higher volumes and less time-critical applications, since the production and setup costs are higher.

You can choose from the envelope formats Maxi Selfmailer and DIN Lang.


Formats
 
Maxi Selfmailer
DIN Lang


The grammage of the self-mailer decreases with increasing number of pages, so that you send your self-mailers always optimized for postage.


Grammage

For self-mailers, we strongly recommend using matte print paper.

You can design your self-mailer with up to 10 pages.

SELF MAILER WITH MINI CATALOG

Combine your self-mailer with a mini-catalog to serve customers up to 4 + 24 pages, e.g. to present comprehensive impressions from a new collection.  In this case, the surrounding self-mailer is also called envelope. In addition to the mini catalog, you can also easily add a perforated reply card to increase customer dialogue.


The grammage for the envelope starts at 130g. With a higher page count we use a weight of 115g to ensure the postage-saving shipping.

The grammage of the mini catalog also decreases as the number of pages increases, so that you can always send your self-mailers and mini catalogs at postage-saving rates.

Starting from 16 pages we use the lighter LWC paper to keep the postage costs to a minimum.
