Key Features

200M-contact B2B lead database for building targeted prospect lists from Sales Navigator URLs, CSVs, or direct search.

Pre-send spam score checker to surface deliverability issues in draft rather than after sending.

Drag-and-drop sequence builder with up to 26 A–Z subject-line variants and eight conditional branch types for multi-step flows.

Mailbox rotation, smart send pacing, and unified inbox to manage replies and protect sender reputation at scale.

AI agent and API access to generate, verify, and launch campaigns from plain-English prompts or programmatic integrations.

Integrations with Gmail, HubSpot, LinkedIn, Salesforce, and Zapier plus custom tracking domains and analytics to monitor opens, clicks, and replies.
