If you're on the enterprise plan, you should have auto delete feature but I don't know if it works for deleting the webhook data table - such an interesting problem - let me know if you could solve it please John T.
i wouldn't use your CTO's email address as it will impact its deliverability for normal use cases- you can purchase some mailboxes from providers like zapmail etc and then import into clay
I used Chrome extension - it's the easiest probably - and then you can import this into Clay for further enrichment.
And no worries, have a great one 🙌
