The E-magazine Spiltennis.nu, which DTF were inspired by Symbiotisk to try, is a success. That the e-magazine can be read and enjoyed anywhere, and that it adapts to all platforms imaginable, gives a great value and ensures that our message gets through. At the same time, DTF are viewed - thanks to the stylish layout and the digital magazine solution - as innovative amongst other federations and the active members of tennis clubs. This label does not make us unhappy.

Mette held a lecture about ”newsletters that work” at our yearly conference on digital marketing in Holstebro. Mette delivered a fantastic top performance with lots of energy and relevant contents, leaving the participants very satisfied. Mette has a convincing confidence and a vast professional overview which gives the participants new inspiration and concrete ideas that they can take with them and implement. It can't be done any better.

Symbiotisk really know their stuff when it comes to Wordpress. They're solution oriented and flexible, and know all the pitfalls in the process up to a deadline.

I truly opened my eyes to the effects of email marketing after a course with Mette Hertzmann, in which I learnt much more than ’just’ creating good content and setting the mail up correctly. I also got tools to increase the opening rate, split-testing and many other exciting things. Mette was generous with tips and experiences from the expert's toolbox - and today email is the marketing activity that gives by far the most return on investment in my business.

Symbiotisk have been fantastic to work with on our websites. They are fast, good and happy and they have a really good ability to understand what our business is about, what we want to express with our sites and how it can be translated into some beautiful, professional websites. We plan to use them many times again and can warmly recommend them to other companies!

Mette has from day one impressed us with her insight and competence within business communication, marketing and optimizing sales through newsletters. We have with more than seven years of experience a large and more technical insight into newsletters, and have therefore entered into a cooperation with Symbiotisk, since their abilities complement Ubivox's perfectly. Mette is, as a super user of Ubivox, combined with her background, an indispensable input into working optimally with newsletters.
Lasse Johansen Partner & Business Developer, Ubivox -
Symbiotisk have delivered a great piece of work in developing and launching the website for my company. Mette and Tore have been really good at translating my visions and wishes into a concrete website layout where my content has the best possible framework to flourish within. Thank you for a well-executed project.

Mette Hertzmann
Partner
Business development, newsletters and consultancy.
I’m a specialist in business development, and strengthening company core communication with newsletters and online media as a sales and marketing tool.
I’m a Global Business Engineer from Engineering College of Copenhagen, specializing in business and product development.
My education and experience from both “old school” and “new school” business management makes me a strong advisor in the processes around business strategy, communication and marketing across generations and platforms.
It is important for me that the companies are well prepared to be able to use their marketing potentials optimally. Therefore I spend a lot of time teaching and presenting to companies that want to get the most out of their newsletters.
Apart from our customers in Symbiotisk I have throughout the years worked for, and with, IBM, Kræftens Bekæmpelse, Tetra Pak, Arbejdernes Landsbank and many others.

David Tolnem

Websites, integration and consultancy.
I specialize in backend programming and integrations, but also javascript and modern web apps on the frontend.
Since then, it has turned into everything from simple marketing sites to shops where purchases were registered directly into the client’s economy system, and international video solutions with integration to content providers and customer- and payment solitions with presentation of the same content in multiple languages on web, set top box and Smart TV.
Apart from our customers in Symbiotisk, I’ve built solutions at or for Yahoo!, Orange, Canal Digital, Telenor, Disney, Politiken, Jyllandsposten and Ekstrabladet.

Tore Vesterby
Partner
Websites, concept development and consultancy.
I’m a specialist in custom building responsive websites in WordPress, that take into consideration where the net is now and where it is moving towards.
I always keep in mind whether the solution the customer imagines makes sense in terms of where the market is and whether the technical solution can fulfill your digital visions.
Since 1996 I have worked with digital media in one shape or another. Yes, back then when the CD-ROM was the next big thing.
I have an MSc in IT from the IT University of Copenhagen and a BA in Danish from RUC with a focus on PR and strategic communication. The end result is that I always think about how best to communicate to your customers on your website – both technically and linguistically.
Apart from our customers in Symbiotisk, I have worked with and for the Ministry of Foreign Affairs, the Danish National Library for the Blind, Arbejdernes Landsbank and many others.
