SMS SMTP Interface

Send SMS through E-Mail even without programming skills.

Usage notes

Email formatting

Messages to the SMTP interface MUST contain ASCII-Plaintext. Special characters MUST be encoded using ISO-8859-1 standard. HTML or any other encoding will be rejected. E-mail- and webmail-clients, sending HTML-encoded e-mails are not suitable for testing purposes (e.g. GMail etc.).

Valid destination addresses


    Sends a plain text message to an SMS recipient. The subject line must contain at least the userkey, the password and the recipient number.


    Optionally, the SMS originator can be specified in the subject line. Use: Originator=MYORIGINATOR

    In case the subject line doesn't accept the necessary number of characters, you can just use the first letter to adress the keyword:
    Userkey = U, Password = P, Recipient = R, Originator = O.


    Delivery status notifications for SMS
    The optional subject line parameter "Notify" can be set to the following values:

    1. Notify=ALWAYS
      Email notifications are sent for the statuses "Delivered","Buffered" and "Failed".

    2. Notify=NONE
      No Email notifications will be sent.

    3. Notify=FAILED
      Email notifications are sent for the status "Failed" but not for the statuses "Delivered" and "Buffered".

    4. <Empty>
      Email notifications are sent for the statuses "Delivered" and "Failed" but not for the status "Buffered".

  2. <Recipient>

    Sends a plain text message to an SMS recipient. Usage:

    From: <SMTP Originator Client>
    To: <Recipient>
    Subject: Originator=<Originator>
    Body: <MessageText>

    Important: SMS recipient numbers must start with 00. The plus character is not accepted by the SMTP interface.


    Subject: Originator=+41760000000
    Body: Hello world!

    The following applies:
    The SMTP interface only processes ASCII Plain Text. Special characters must be encoded in ISO-8859-1 standard. HTML or other code are rejected. E-Mail and webmail clients that send HTML-encoded e-mails are unsuitable for testing (eg GMail etc.).

    The subject is optional. If no originator is defined, the ASPSMS system sets the Originator 'SMS' or uses a predefined default Originator (eg +417912345678).

    Authentication is based on the sender's e-mail address (SMTP Originator)*. This e-mail address should be different from the ASPSMS account e-mail address. Before SMS can be delivered to <Recipient>, the used e-mail sender address must be authorized.

    (* This implicit authentication by SMTP Originator means that the sender email address is the "secret" and not the usually used combination of Userkey and password. You therefore should choose an e-mail address which is different from the account e-mail address. It should not be self-explanatory and you have to keep this e-mail address secret, similar to your combination of Userkey and password.)

    Sends an XML formatted message to the ASPSMS system. For further information on the required XML format see:

    Any XML reply from the system will be routed back to the sender's address of the request E-Mail. If there is no sender address, the XML reply will be silently discarded.

    The subject line has no meaning for this destination address, and can be left empty.

Outgoing mail server

To send emails to the SMTP interface, you can use your own outgoing mail server, the outgoing mail server of your Internet service provider or the ASPSMS outgoing mail server. Using STARTTLS on port 25 or port 587, the delivery of SMS jobs to the ASPSMS system using the SMTP interface is encrypted end-to-end. For this reason, we recommend using the ASPSMS outgoing mail server via port 587.

Authorized SMTP Originators

In order to use the SMTP interface for sending to recipient addresses according to the pattern, the used sender e-mail address must first be authorized as SMTP originator. This implicit authentication by SMTP originator means that not the combination of userkey and password is the &quo;secret&quo;, but the used sender e-mail address. It is therefore important not to select the e-mail address used in a self-explanatory way and to keep it secret just as carefully as the combination of user key and password. For each authorized SMTP originator a standard SMS originator can be defined. This is used if no SMS originator has been set explicitly.
