What types of data can be used to create a tailored audience?

To create a tailored audience in Twitter Ads, you can use the following types of data:

1. Email addresses: You can upload a list of email addresses that you have collected from your customers, leads, or website visitors. Twitter will match the email addresses with their corresponding Twitter accounts.
2. Twitter usernames: You can upload a list of Twitter usernames that you want to target. Twitter will match the usernames with their corresponding Twitter accounts.
3. Mobile advertising IDs (MAIDs): You can upload a list of MAIDs that you have collected from your mobile app users. Twitter will match the MAIDs with their corresponding Twitter accounts.

It's important to note that the data you use to create a tailored audience must be collected in a lawful and transparent manner, and must comply with Twitter's policies and guidelines. You should also ensure that you have obtained the necessary consents and permissions from your customers or users before using their data for advertising purposes.

Additionally, Twitter has strict rules around the use of sensitive data, such as racial or ethnic origin, political opinions, religious or philosophical beliefs, trade union membership, health information, sexual orientation, or criminal history. You should not use sensitive data to create a tailored audience or target your ads.
