Integration details
Description
VerticalResponse helps users search contacts, inspect contact details, manage contact lists, sample random contacts, export sanitized contact data, create and update draft email campaigns, send test emails, launch or schedule campaigns with explicit confirmation, and review email campaign performance from ChatGPT. The app supports a deterministic OAuth review demo account, uses explicit validated inputs for contact and campaign fields, never exposes credentials or raw API responses, and does not implement delete tools for campaigns, contacts, or lists.
