Language Support for Contacts

SlickText allows you to capture and store the preferred language of your contacts. You can enter a contact’s preferred language manually or upload it as part of a bulk import of contacts. Click here to learn more about adding contacts in SlickText.


To view or change a contact’s preferred language:

  1. Expand Audience on the left navigation bar, then choose Contacts.
  2. Click on a contact or click the three dots to the right of the contact and choose edit.
  3. Scroll down on the contact form until you see Language. 
  4. Make any necessary changes. Click Save.

SlickText also uses AI to auto-detect a contact’s preferred language. If the contact’s current language is set to “None,” SlickText’s AI will read each message sent from a contact, attempt to determine the message’s language, and then update the language field on the contact record. If a contact clicks on a link you sent from SlickText, SlickText will attempt to determine a language preference by reading the preference set on the contact’s browser. SlickText will only update the field if it is currently set to “None.”


You can create a segment based on a contact’s language preference. Use the segment to send different messages based on a contact’s language.
