Error: Maximum Columns Limit Reached in Database Setup

I'm receiving the same error as mentioned here: You have reached the maximum number of columns allowed (100 total columns, 40 action columns). Please delete some columns before adding new ones.

To resolve the "maximum number of columns allowed" error, you need to delete some existing columns before adding new ones. Column limits by plan: ** Standard tables: 70 total columns, with up to 30 action columns ** With waterfall: up to 40 action columns ** Enterprise plan: up to 40 action columns per table *Solution: Delete completed enrichment columns after retrieving their data to free up space for new action columns. This allows you to add new enrichment columns while staying within limits. For unlimited rows and higher column limits, consider upgrading to Enterprise plan.

Hi there, Thank you for reaching out to the support team. I just tried adding a phone number waterfall and it worked perfectly. Can you show me via a screenshot or quick loom how you're adding the waterfall and the error you're receiving? I look forward to your response!

In the meantime I created new tables where it does work

When I choose for global phone numbers instead of US and Canada it does work though

Okay thanks for the additional context! To clarify, you're only seeing the error when you use the US and Canada phone number waterfall? Any other context would be useful as I troubleshoot this internally. I look forward to your response.

I get exactly the same problem. My columns in this table are way under my plan limits. I add US and Canada phone enrichment and I get the error.

Hi there, Based on your table it seems that you are hitting the 40 action column plan limit. If you add another waterfall to this table then it takes you over the 40 action column limit. An action column is any column in your Clay table that: * Performs data enrichment • Executes integrations with external tools (like Salesforce, HubSpot, Close) • Runs automations or workflows • Processes data through APIs or webhooks Let me know if you have any further questions.
