Being ‘different’ in today's world is a good thing. Unique shapes and packaging, combined wi­th name and address personalisation will make your mail campaign stand out. In a world oversaturated with marketing, standing out and being seen is half the battle for any campaign.

If you’re not already familiar with the word Custom Mailer it’s the industry term for a One-Piece Postage Item, or "Self-mailer". No outer carrier is required. Secured in such a way that it becomes the envelope, marketing tool and response mechanism all in one. Neat huh? The effective Custom Mailer would replace all three elements from your traditional direct mail pack.

The versatile Custom Mailer lets you start your call to action message immediately, increasing the likelihood of the customer opening your piece to find out more. Whether it is to donate, buy, respond or simply engage.


Further to this, the advantage of a Custom Mailer is the opportunity to design and pre-populate the response mechanism. Imagine how easy subscribing, buying or donating would be if all of your personal details and shipping information were already there? All you had to do was sign and return in the integrated, postage-paid envelope. Mission accomplished!

Mailers, on design alone usually achieve a better open and response rate, but don’t discount the other important elements of personalisation, copy, creative, relevancy and a clear call to action.
