Does the "STOP" function work on messages sent abroad ?
The STOP SMS function only works on messages sent to France (regardless of whether they are French or foreign numbers). To allow the unsubscription of contacts located abroad, it is necessary to use an unsubscribe link inserted with the variable as below :
SMS sent from the same campaign contain a different STOP number, is this normal ?
Yes, this behavior is normal because the number changes depending on the router used for SMS delivery. On the same campaign, several routers send the messages to ensure that everything will be delivered as quickly as possible. When a message is sent to a router, the STOP number changes to allow them to collect the unsubscribe request and forward it to Splio.
The customization of the SMS sender name does not work on messages sent to France, why?
The personalization of the SMS sender name (Sender ID) works if and only if the message contains a mention and STOP number. In practice, the customization of the messages sent on the French network is possible only if the message contains:
- a "STOP" mention
- an unsubscribe number
In case of problems please check the presence and conformity of these elements. They must appear in the format "STOP 36XXX". All these rules are not valid on SMS sent abroad (Spain, Italy, etc.).
Can I send an SMS campaign to contacts with blacklisted EMAIL?
By default, email and SMS blacklists are not synchronized. A contact with blacklisted email can be targeted normally by an SMS campaign if it is not in the SMS blacklist.
