Mixvoip has a mail to sms option that operates by sending an e-mail to destination@smsu.eu. The message to be send is taken from the e-mail body, and if no message is found inside the e-mail body, the subject of the e-mail will be used as SMS message.

Create a new mail where the recipient is the mobile number followed by the domain @smsu.eu, paste your FAX key provided by Mixvoip in the subject and write your message in the body message.

Recipient: (+XXX)NUMBER@smsu.eu
Body Message: Your Message

Authentication in the destination header

If you can not change the e-mail body, then you have the option to put your fax key into the destination header (To:) of your email. Just take the fax key and add it after the recipient’s phone number but do not forget to strip the “:”.

Example: +352691234567fk15805-0938efc33d@smsu.eu

The message body

We try to guess or extract the message out of your e-mail by applying some filter rules.

  • We cut of the message after “–” because that is normally the start of the e-mail signature
  • We do not filter after the “<html>” tag
  • To make sure that no extremely long messages are sent, we cut the e-mail body at 300 characters
  • If the message inside the e-mail body is empty, we use the subject as message text
