Overview
GMass
GMass turns your regular Gmail or Google Workspace account into a full-featured email marketing platform. You can send mass emails, create complex mail merges using Google Sheets data, and schedule automated follow-up sequences that stop once a recipient replies. It lives entirely inside your Gmail interface, so you don't have to learn a new dashboard or export your contacts to external software.
You can use it to bypass Gmail's sending limits by connecting to external SMTP services or stay within standard limits for smaller outreach. It solves the problem of low engagement by making every mass email look like a personal, one-on-one message. Whether you are a recruiter, salesperson, or non-profit organizer, you can manage your entire outreach strategy without ever leaving your inbox.
Wunderkind
Wunderkind helps you unlock hidden revenue by identifying the anonymous traffic hitting your website. Instead of losing touch with visitors who don't sign up, you can recognize them across devices and trigger high-performing, personalized messages. You can scale your reach by sending automated emails and texts based on specific user behaviors like cart abandonment or category browsing, ensuring your marketing hits the right person at the right moment.
The platform integrates directly with your existing tech stack to supercharge your performance marketing. By focusing on first-party data and identity resolution, you can decrease your reliance on third-party cookies and expensive retargeting ads. It is primarily designed for mid-market and enterprise e-commerce brands looking to maximize their owned-channel conversions and build long-term customer relationships.
