Keyword Rules & Limitations

To ensure your SMS Keyword Opt-in works correctly and remains compliant, keywords must follow these rules:

  • Keywords must be between 3 and 20 characters long, can be one word or more. 

  • Only letters (A–Z) and numbers (0–9) are supported. Special characters, spaces, or symbols (such as ! @ # $ % _ - /) are not allowed.

  • Keywords are not case-sensitive, meaning “SALE”, “sale”, and “Sale” will all trigger the same opt-in.

  • Each keyword must be unique and can only be connected to one opt-in tool at a time.

  • Reserved system keywords such as STOP, HELP, UNSTOP, and UNSUBSCRIBE cannot be used, as they are required for compliance and opt-out handling.

Please note:

  • Once a keyword is created, it cannot be edited or renamed. If you need to change the keyword text, you’ll need to create a new Keyword Opt-in Tool.

  • Keywords will only collect subscribers if both the Keyword Opt-in Tool and the connected Welcome Message are active. If either is inactive, new subscribers will not be added.

Keywords sent with special characters such as ?, !, -, etc will be recognized and will subscribe the user to your list.

On the same page, you will be able to track how many people subscribed to your list via the keyword opt-in tool in the Subscriptions column.

If you click on the keyword you can modify the attached welcome message, on the other hand, you will not be able to modify the keyword’s name. You will also find our recommendations about sharing your keyword on this page.

Stay compliant when advertising your Keywords

Text marketing legal requirements apply to keyword-type opt-in tools as well!

Make sure you add the compliance language that informs your audience they are opting-in to text messages from your store disclaimer on every channel you advertise your keywords, including online and offline.

Copy the below text and replace [STORE NAME] with your brand’s name.

By texting, you agree to receive recurring automated promotional and personalized marketing text messages (e.g. cart reminders) from [STORE NAME] at the cell number used when signing up. Consent is not a condition of any purchase. Reply HELP for help and STOP to cancel. Msg frequency varies. Std Msg & data rates may apply. View our Privacy Policy and Terms of Service.

Please note that in case you can not link your Privacy Policy and Terms of Service, you are supposed to add the URLs that direct to these documents.

Some examples of a compliant keyword opt-in advertisement👇

  • Website banners or email newsletter banners

  • Social media, posts, cover pictures, stories

  • Printed flyers, posters, business cards


👉 Pro tip: Create separate keywords and welcome messages for each platform or campaign where you collect subscribers with this type of tool. Only this way you will have accurate statistics! In case your keywords are advertised on multiple platforms, we will not be able to display statistics separately.

 

Using Keywords for Targeting

Subscribers who join through a keyword can be segmented and targeted based on that opt-in source. This allows you to send more relevant, personalized campaigns to specific groups of subscribers.
