Our amazing customers

Learn how our customers use Standard & Premium

Quick and easy communication with customers

NEMADVOKAT (translates to: EASYLAWYER) labels itself as Denmark’s digital law firm. Their concept is to digitize as much of their legal counsel as possible, so everything from meetings, documents and signing of documents are handled digitally through their platform.

NEMADVOKAT has opted for the Standard Message Class to welcome new customers, send passwords and to notify customers when documents are ready to be signed.

Today NEMADVOKAT has communicated with several thousands customers as well as companies in relation to the purchase and sale of properties, start-up of companies, defence counsel, trademarks and so forth.

How the Danish Red Cross handles SMS donations

The Danish Red Cross uses GatewayAPI to broadcast SMS campaigns and handle SMS donations in Denmark.

For donations, the Danish Red Cross uses the Premium Message Class as well as their own short code (1290) with a variety of keywords related to different campaigns connected to it.

When a mobile user sends an SMS to the Danish Red Cross with a specific keyword, a fixed amount is automatically deducted from the user's mobile account.

Additionally, donations from mobile users are used for lead generation, which can later be turned into permanent supporters.

How Realkreditkonsulenterne uses Premium Message Class

Realkreditkonsulenterne is a Danish online-service that helps customers with their mortgage loans. After you have entered your address, Realkreditkonsulenterne will tell you whether you should restructure your loans, change bank, or negotiate a lower interest rate.

Martin Riedel, owner of Realkreditkonsulenterne, explains: "It was important for us that the SMS API we chose was secure since our messages contain sensitive information. The anonymized flows in Premium Message Class suited our needs perfectly on this part.

Additionally, we don’t need to spend resources on marketing an app to new and existing customers. Instead, when people have signed up to our service, they can opt-in to receiving SMS messages from us. There is something really powerful about SMS messages: Most people read SMS messages instantly and are more likely to act after reading an SMS than after reading an email."
