Need help with Regex
Hi team,
I want to include a set of users to an existing segment. This segment will be used for exclusions in all promotional campaigns. Let's call that segment as Level 3. The set of users are subscribers for a specific product. I know that I can't create a segment only for these set of users and include that segment in Level 3 as Level 3 is used in all marketing campaigns and Braze doesn't alllow me to do that. Therefore, one way to bell this cat is to use a "match regex" filter condition in Level 3 to identify that cohort that I want to exclude. The regex can target a custom attribute called "Active_Accounts". The "Active_Accounts" is a string and lists all the active account numbers for the user. The account numbers are comma separated and the product that I am targeting ( for the set of users) appears as the first value in "Active_Accounts". The account number for the set of users will follow this pattern : oabc-32HABHCPUV {10} or odefg-12AAAAAB {8} etc. But the account number always starts with a 'o' (lower caps). Need help to create a regex that I can match from the "Active_Accounts" so I can include this set of users in Level 3 using the match regex filter
