E-mail marketing to consumers

The consent of the addressee is required before you can send an e-mail to a consumer address. Such consent is normally obtained using a double opt-in (DOI), meaning that the recipient has to confirm his consent by e-mail a second time. After this, nevertheless, the recipient may only be contacted by the business that obtained the consent. This means that you cannot buy e-mail addresses with opt-in and then write to them yourself.

We will assist you in attracting new customers by e-mail, both legally and with an eye to costs. Our network of mailing partners is at your disposal for this purpose; they can provide a wide range of different e-mail mailing lists. Depending on the mailing list in question, the e-mail addresses can be classified into segments using different criteria (e.g., according to gender, regional criteria or fields of interest), thus reducing your wastage.

We will also help you reach your target group in another way: small ads in one of the numerous newsletters for specific fields of interest enable you to reach individuals who have very special interests.

We would be happy to look into whether you can achieve your marketing objectives with e-mail marketing and which mailing lists offer you the greatest benefits. Get in touch with us now!
