Why can't i create more columns in my tables.

You're likely hitting one of Clay's column limits. Each table has a maximum of 70 columns total, with specific limits on action/integration columns: ** Up to 30 action or integration columns per table ** This limit increases to 40 if you implement a waterfall If you're on the 50k credits plan and can't add more columns despite being under the overall limit, you might be hitting the 30-column limit for enrichment columns. In this case, you'll need to delete completed enrichment columns after retrieving your data to make room for new ones. This can be especially challenging with setups like email waterfalls, which may use up to 20 enrichments alone.

Hey there do you mind sending the link (url) to the table so we can take a look?

Hey there, thanks for reaching out! We currently limit tables to 50k rows, 70 columns and 30 enrichments per table. We do this to ensure we can continue providing excellent performance across the board. If you've run out of columns, we'd recommend checking to see if there are any columns/enrichments that you aren't currently using. If there's anything else I can assist you with, please let me know! 😊 Have a great Tuesday, Daniel
