What is Apollo?

Apollo is an AI-driven sales platform that empowers teams to master the art and science of email warmup. By combining industry-leading sales intelligence with a suite of engagement tools, Apollo helps you gradually build sender reputation, improve deliverability rates, and ensure your messages land in the inbox. Whether you’re launching a new domain or scaling high-volume campaigns, the platform’s intelligent automation and data-driven insights streamline your warmup process and keep your outreach on track.

Email warmup refers to the practice of gradually increasing your outbound email volume while monitoring engagement signals like opens, clicks, and replies. This method trains mailbox providers—Gmail, Outlook, Yahoo—to recognize your domain as trustworthy. A consistent warmup schedule reduces spam flags, bolsters sender reputation, and maximizes inbox placement. With Apollo’s unified go-to-market platform, you can orchestrate this process alongside data enrichment, sequence automation, and performance analytics.

What began as a simple prospecting database has evolved into an end-to-end command center for sales execution, including built-in email warmup capabilities.

Today, Apollo serves over 35,000 customers worldwide—from bootstrapped startups to Fortune 500 enterprises—processing more than 200 million monthly email interactions. The platform’s continual innovation earned accolades for best-in-class data accuracy and workflow automation, positioning Apollo as a trusted partner for growth-focused teams.
