The Four Types of Letterbox Marketing

There are four flavours of letterbox marketing. Some are better for acquiring new customers while others are better for retention or reactivation. All are excellent for targeting and some require little or no work to ensure GDPR compliance.

Along with door drop, direct mail is the backbone of letterbox marketing. It’s a fantastic, uncluttered channel that allows your brand and messaging to achieve amazing cut-through and ROI.

Data to fuel your Campaigns

Sustainable mail

As a B-Corp, our goal is to become the UK’s most sustainable marketing agency. That’s why developed our own climate positive postage brand – Enviromail – to offset double the CO2e that’s created during distribution (for free!). Not only do we use carbon neutral printers alongside carbon balanced papers, inks and printing processes to ensure your direct mail campaigns are as green as possible. We’ve also developed our own carbon calculators to ensure all your letterbox marketing campaigns have a net zero impact from start to finish.

No other marketing agency offers Webmart’s level of sustainability.

Cost reduction

One of the great things about coming to Webmart is that we have our own in-house procurement team, here to find the best direct mail suppliers in the UK. That means not only can we show you the latest innovations and ensure your productions run without a hitch, but it also means we’ll find the best-fit suppliers for your project and reduce your costs.

Mail as part of your integrated marketing

Mail is incredibly effective as a standalone channel – according to Marketreach it has an average engagement rate of 95% – but it works even harder as part of a multichannel campaign. Webmart’s consultants are experts in advising on your channel mix and ensuring a consistent omnichannel experience.

Design and Creative

Not only do we advise, consult and deliver your direct mail, but Webmart also specialises in designing superb direct mail pieces. Our in-house team has worked with some amazing brands to carefully enhance their brand and produce direct mail that really delivers.

Marketing Portal

Webmart’s online portal gives you real control and insight of your ongoing mail campaigns. It’s free to all our customers and lets you to specify, price, order and see the progress of your letterbox campaigns as they’re produced. We also provide a suite of reports along with Mailmark reporting of your campaigns as they’re delivered to your customers.

Don’t just take our word for it

The team have been fantastic and a pleasure to work with, a real credit to Webmart. Nothing has fazed them; they totally understand our service offering and buy into our purpose (which I believe is key). Added to this is clear communications, expectation setting and on time delivery.

CEO, Thyme

I liaise with Webmart from the moment I log on to the moment I log off and it feels like a collaboration rather than a client vs. supplier relationship. He’s super friendly, efficient and knowledgeable which makes my working day that much better. I know if there’s any issues, I can call him any time of day and he’ll do everything he can to help, and vice versa! I have nothing but good things to say and have never had a bad experience.


Thank you so much for all your work on the latest mailing. We were saying how great it is to work with Webmart as we have faith that you will get things done – you do things when you say you’re going to – it’s quite refreshing (unfortunately). Thank you!
