The technology behind Ubivox


Historically reliable foundation

Ubivox builds upon 9 years of experience with newsletters, as well as 15 years of experience with programming and daily operation of advanced systems, having solved most of the technical challenges one can encounter.

Ubivox is primarily programmed in the language Python, which is also used amongst others by Google, Yahoo, and NASA.

  • Over 9 years of experience with development and operation of software for newsletter delivery.
  • Profesionally developed software, hosted on reliable solutions in Denmark.
  • Architecture that gives flexibility and minimizes the risk for crashes.

We are building this on a reliable platform delivered by one of the largest hosting providers in Denmark, and an architecture which allows us to add and remove resources within minutes.

The entire platform is replicated between to physical systems, which minimizes the risk for long lasting downtimes.


Millions of mails requires reliability

Behind the userfriendly interface we are constantly working on making sure our software is secure and reliable and that your e-mails reaches your recipients.

It may sound simple to send an e-mail, but the premise changes if you suddenly need to deliver 10,000 e-mails, 100,000 e-mails of several millions of e-mails which we does every day.


Monitoring is key

We monitor our ongoing deliverability through a set of tools delivered by the largest providers. Furthermore we use SPF/Sender ID, DomainKeys/DKIM, automatic bounce handling, separation of recipients clicking the Junk button, and much more.

This work improves the possiblity that your newsletter escapes the spam folder and instead appears in the middle of the inbox where the likelyhood of it getting read is best.
