Opt-in consent is required from handset users. It is also suggested that handset users must also be provided with a free, readily accessible process for opting-out of future messages.

Best practices for delivery:

1. Warm-up Campaign
   - Send test messages to legitimate and active numbers.
   
   - Make sure these tests messages will be opened.
   
   - Click on the link and navigate to the website.
   
   - These steps will help validate the reputation of your url.
   
   
2. Shortened URLs
   - It is important to avoid using public shortened domains (like bit.ly, tinyurl, etc)
   
   - Best recommendation is to use private shortened domains, to reduce your blocking/spam risks.
   
   
3. Domain Randomization
   - For high-volume campaigns, it is advised to randomize domains in URLs used within the same campaign. 
   
   
4. Message Content
   - Avoid aggressive content/language and false promises of unrealistic percentage-based earnings. 
   
   - We advise to use the ID of the Gambling company in the beginning of the message.
   
   
5. Volume Testing
   - Avoid sending large testing volumes to the very same number.
   
   Note: Once the traffic classified as SPAM, it is very difficult to improve the short code reputation again.
