The Text Message Deliverability Recommendations section is a built-in tool within the text message editor that helps you gauge how likely your text message is to pass carrier spam systems.
RecommendedA carrier violation effectively means that the carriers (AT&T, Verizon, etc.) flagged your message as SPAM and are actively blocking message delivery.
DailyStory maintains a list of over 1,500 words and phrases known to impact carrier deliverability. For example, a low-impact phrase may be "get 15% off," whereas a higher-impact word or phrase uses terms that may cause carrier violations.
WarningOur tool may not include every restricted term or phrase — particularly around product categories, product names, or attempts to misspell words — but the carriers do scan for and block based on these.
Including URLs in your text message does impact deliverability. The content of the page at that URL can also affect delivery, since some carriers follow links in text messages and inspect what is on the other end.
DailyStory's deliverability tool examines your destination page's content and may display a warning if potentially troublesome content is found.
We strongly recommend shortening your own URLs using a domain that is unique to your company. Public URL shorteners such as bit.ly are known to cause issues and should be avoided.
Shared shortener domains like bit.ly and goo.gl are used industry-wide for messaging of every kind — including spam and unwanted content — which is why carriers actively filter them.
DailyStory has a built-in shortener (txts4.me) that is used automatically when "Track Clicks" is enabled. However, if the content of the destination page is flagged by carriers, you will be required to use a password-protected link. For high-volume senders, we recommend setting up a custom SMS URL shortener on a subdomain you own.
You also cannot use a DailyStory Tracking Link in a text message.
Short codes are held to a higher trust standard than 10DLC long codes by carriers, which means URL filtering is more aggressive on short code traffic. A URL that delivers without issue from a 10DLC number may be filtered when the same content is sent from a short code.
Carrier filtering on short codes is often silent. The message will appear as Sent in your delivery report but never reach a Delivered status. If you are sending a URL from a short code and not seeing delivery confirmations, check the delivery report — a Sent-but-not-Delivered pattern is the typical signature of carrier-side URL filtering rather than a sending failure.
WarningShort codes are registered with carriers for a specific use case (the campaign brief). URLs that do not match the registered use case — for example, a promotional landing page sent from a short code registered for appointment reminders — can be filtered without any error returned to DailyStory.
For these reasons, a custom URL shortener on a subdomain of your own domain is especially important when sending from a short code. The shortener domain is one of the strongest trust signals carriers evaluate, and shared shorteners (including DailyStory's built-in txts4.me) inherit the deliverability history of every customer who has used them.
