Why do text messages occasionally not send to my members?
Every text message that's delivered across any mobile carrier (e.g., AT&T or Verizon) is evaluated by each company in real-time, and is either rejected as spam or accepted and delivered to the mobile user.
Some guidelines to keep in mind that, though not 100% as carriers use machine learning to constantly change what's approved and what's not, will help with message delivery rates:
- Keep the messages short and meaningful
- Shorten URLs (using a service like bit.ly or the like)
- Do not send only a URL as a response; instead, start the message with a short piece of text and then use the shortened URL
- Use standard sentence structure and capitalization; avoid using all-caps
Bottom line, each message that's delivered to carriers is evaluated in real-time as to whether the message is spam, and is either accepted or rejected immediately. Carriers constantly evolve and change their opinions on what does - and does not - constitute a "spammy" text message.
By following the guidelines above, your delivery rates will be as high as possible across the various carriers!
