- Avoid using public URL shorteners like bit.ly, goo.gl, and tinyurl. Public URL shorteners are used by many spammers and thus they are mostly blocked on toll-free numbers. It is recommended that you create a custom URL shortener that is only used by your brand and should ensure that you include this detail in your submittal when you send your campaign information to Sinch.
- Ensure you have a valid opt-in from your user base. Opt-in is essential when messaging any of your consumers.
- Consider having a double opt-in process whereby you are ensuring your customers are completing the necessary steps to opt-in to your campaign.
- Support HELP and STOP commands. Just like when using a short code, ensure customers receive information when they text in HELP, and ensure they’re opted-out of your campaigns when they send in STOP to your TFN.
- Use one TFN for your messaging. Do not use several different TFN’s to message your consumers. This is a bad practice and will most likely get you shut down at the carriers. Use one TFN and if you use it correctly, you should never have a problem.
- Set expectations with your customer on the frequency of messaging. Sending too many will result in higher than average opt-out rates. Set the expectation with the consumer and stick to it.
