You can access a database of over 275 million contacts to find your ideal prospects and use built-in engagement tools to reach out to them directly.

The platform also provides AI-powered insights to help you prioritize high-value leads and improve your conversion rates. Whether you are a solo founder or part of a large enterprise sales team, you can use these tools to build a predictable pipeline and hit your revenue targets faster.
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.
