Mixvoip has a mail to sms option that operates by sending an email to destination@smsu.eu. The message to be sent is taken from the email body, and if no message is found inside the email body, the subject of the email 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 email 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 of your email by applying some filter rules.

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