Hey Jaycee, Thanks for the questions! I’m fetching data from a **specific form** only, and I don’t need any additional contact information—just verifying if the email exists in submissions. Currently, the response time is around a minute since I’m dealing with ~2 lakh records, but I’m hoping to bring it down to just a few seconds. I agree that searching the contacts for the email first and then fetching form submissions sounds promising, especially when the email doesn’t exist. However, in cases where the email does exist, this approach would involve two API calls, which might actually increase the response time further. Let me know if you’ve encountered a more efficient workaround! --- _[View the full topic](https://community.hubspot.com/t/api-based-email-validation-in-a-hubspot-form/122787)._
