What is Mocke (YC S22)?
Mocke AI agent mocks running email campaigns. Get back results in 1 min, such as open, reply or unsubscribe. Mocke also reveals why each lead didn't open emails, reported spam or ignored. Unlock insights of campaign failure (or success!) not seen in real life.
Problem
Users need to run actual email campaigns to gauge effectiveness, which takes time and risks spam complaints or unsubscribes. Unable to predict campaign success before launching leads to wasted resources and damaged sender reputation.
Solution
AI-powered email campaign simulation tool. Users can input campaign details and receive metrics like open rates, reply rates, and reasons for failures within 1 minute. Mocke AI agent mimics real-world email interactions, revealing insights like why leads ignored emails or marked them as spam.
Customers
Sales teams, marketers, and entrepreneurs running cold email campaigns. Demographics include B2B professionals aged 25-45, focused on lead generation and conversion optimization. User behavior: Regularly A/B test email copy, prioritize email deliverability, and track campaign ROI.
Unique Features
Instant simulation of full campaign outcomes (including granular failure reasons) without sending real emails. Provides actionable feedback unavailable in real campaigns (e.g., 'Lead ignored due to irrelevant subject line')
