Hi User,
Sending URLs in Text Messages
Including URLs in text messages is an effective way to share information with your recipients. However, spammers often use links to perpetrate scams, which has prompted major carriers to implement filters to block suspicious messages. Below, we provide guidance on best practices for using links in your text messages to minimize the risk of filtering.
URL Shortening
Do not use shared public URL shorteners, such as TinyURL or free Bitly links, in your messages. U.S. carrier policies strongly discourage their use and require that any URL shortener be proprietary and properly branded to your business. While some countries may not strictly prohibit public URL shorteners, it is generally not advisable to use them. To avoid potential filtering, we recommend using a dedicated short domain specific to your brand.
Blocked URLs
Certain URLs are actively blocked due to abuse by scammers. Here is a list of currently blocked URLs:
- 9qr.de
- alturl.com
- app.link
- bc.vc
- bit.do
- bit.ly
- bitly.com
- bitly.ws
- budurl.com
- clicky.me
- cutt.ly
- is.gd
- lc.chat
- linki.la
- lnkd.in

- rb.gy
- rebrand.ly
- s2r.co
- serveirc.com
- shrtco.de
- soo.gd
- t.ly
- tiny.cc
- tinyurl.com
Using Controlled Domains
When sending URLs, it is best to use domains you control. For example, using a domain like mybusiness.net ensures that only your business can send links with that domain, protecting against the risk of another user linking to inappropriate or spammy content. While it is permissible to use public domains, this practice increases filtering risk as another user could send harmful content and trigger a filter on that shared domain. Additionally, obfuscated URLs are often flagged by carriers as potential phishing attempts and may be filtered.
Following these best practices will help ensure your text messages are delivered successfully and in compliance with carrier regulations.
