  • Your message has been identified as having to the undesirable messaging category by the Twilio message screening system as spam or another type of unwanted communication.

So, you should follow the answer given below. If the problem still happens, check the list of error messages to find out how to fix it.

How to prevent the Twilio error code 30007 from happening in the future?

Consent and opting-in

  • Send communications solely to mobile users who have given consent.
  • Identify who sent the message and how to unsubscribe. You must provide opt-out instructions monthly if you contact the same receivers multiple times.
  • Your opt-out phrase must include a commonly used keyword. Reply STOP to unsubscribe in the US and Canada. “Text 2 to opt out” is not compliant and will be filtered.
  • If you send messages to users over a lengthy period, check in with them every 18 months to be sure they still want them. The mobile number you’re sending to may have changed hands, or the recipient may not recall approving.
  • Daily deactivation file processing. You no longer have permission to send to a deactivated phone number.
  • Watch for an increase in opt-outs and consumer concerns. This means your consent or opt-out methods require fixing. As phone numbers receive complaints/high opt-out rates, carriers will filter or prevent traffic.

Aim and Choosing a Sender

Twilio error code 30007
  • Twilio’s SMS guidelines vary by country. Twilio updates these pages with country-specific best practices.
  • Before sending SMS or MMS to the US or Canada, ensure your use case isn’t banned.
  • Use only the Twilio phone numbers your business needs. Twilio’s Messaging Policy prohibits sending messages across multiple phone numbers to avoid message filtering. Multiple business locations or geographic areas are viable reasons to use various Twilio numbers.
  • All application-to-person traffic must be sent from a short code or a pre-registered Alphanumeric Sender ID, if available. These are two ways carriers can assess your messaging use case and improve delivery. Some nations like France restrict using local numbers for Application to Person transmission. Alpha Sender ID, if available, or a foreign number can be used for 1-way Application to Person communications. Check the country’s SMS Guidelines if unsure.

Message contents

  • Do not submit links truncated with TinyUrl or Bitly. US carrier laws discourage the use of public URL shorteners and require that yours be proprietary and branded details here. Other countries may not ban URL shorteners, although it’s not recommended. Use a dedicated short domain to shorten URLs in your communications. 
  • Send URLs/links from domains you control, if possible. Similar to abbreviated URLs, use a business-specific URL when sending links. If you own the domain mybusiness.net, you can be sure that no one else is using it to send inappropriate URLs. URLs used by other services/people are allowed and do not guarantee to filter. Another user of the URL domain could submit spam or offensive content, flagging the domain. Obfuscated URLs in spoofing/Fraud efforts will be screened.
  • Avoid emojis, extraneous special characters, and misspellings. These messages are usually constructed to elude detection. Thus they will be filtered.
  • Send no illegal or carrier-banned content. For more information, see Forbidden SMS and MMS categories in the US and Canada.

Don’t let someone else take over your account.

If your Twilio Account SID and Auth Token fall into the wrong hands, your account could send spam. To prevent account takeovers, keep your Twilio password safe.

  • See Store Your Twilio Credentials Securely for details (Twilio Docs).
  • See Proactive Steps for Customers Suspecting Account Takeover if you feel your account has been compromised.
