To include a contact in an SMS campaign, ensure that a mobile phone number is included in their contact information within Sendinblue in the SMS attribute field (including the + sign and the country code).
There are currently three ways to add a phone number to the SMS attribute.
- Manually fill in the SMS attribute for an existing or new contact. Learn more in Add a single contact to Sendinblue.
