Sender ID guidelines: Alphanumeric sender IDs are not supported and may be changed to a short code or local number to ensure delivery. Numeric Sender IDs are not allowed unless offered as part of a two-way service. Generic sender IDs such as INFO, SMS, NOTICE, etc. are prohibited.
Use cases and content: Before sending marketing messages, consent from recipients is required. It is also recommended that recipients are offered a free and easily accessible option to unsubscribe from future messages. For gaming-related content, the content must be registered and follow specific guidelines. Consent from recipients is also needed here.
Best practice for delivery: It is recommended to conduct a warm-up campaign by sending test messages to legitimate and active numbers. It is important that these test messages are opened and that links in the messages work properly to validate the URL's reputation. Avoid using public shortened domains and it is best to use private shortened domains to reduce the risk of blocking and spam. For high-volume campaigns, it is recommended to randomize domains in URLs within the same campaign.
