Important information

New platform, new domain – Affecting email addressing and API calls


Service Window: Friday May 5 19:00 (CET +1) – Monday May 8, 8:00


The migration will generally cause no service interruptions, you will be able to send SMS and use other services as usual.

Why the service window?
We are migrating to a new platform, therefore we will start using a new domain which will be used as the originator for e-mail from us to you as well as in the API calls. Overall, everything will work the same way it has before.


Possible service interruptions during the window
Some of our services might be subject to shorter interruptions – these are the ones connected to ebox.nu, such as link-SMS, secure messages, electronic signing and payment request.

! ALSO AVOID updating distribution lists within the service window, such changes might be lost in the process.


To do prior to the service window
For those who have developed applications built around emails from us(such as receipt handling, incoming SMS and incoming fax), actions must be taken prior to the service window – prepare your application for receiving emails from the domain @tellustalk-eu.appspotmail.com.

For the customers whom are aware that email usually gets stuck in their spam filter, also make sure to whitelist emails from the domain @tellustalk-eu.appspotmail.com.


To do post-service window
No immediate actions are needed, we will return with instructions once the service window has been closed.

In short, the following will (in time) be required:
For API-users: Change the URLs you are using from tellus-talk.appspot.com/xxxxx to tellustalk-eu.appspotmail.com
This also applies to the ones who use Outlook’s integrated SMS service.
For the ones who use shortcuts: replace them.

For the ones whom have also made their own manuals for their users, update them. 

If you would like to stay updated about our migration:

– Send the word Start in the subject field or as a text in your email to the email address group=4672080|eu@esms.nu
(it might look fishy but it really works!)
