Built for teams running outbound at scale on Apollo.io, not just enrichment. Exposes 27 tools covering the full operational surface: sequence management, campaign health digests, mailbox warmup monitoring, programmatic template editing, contact enrollment, and daily send cap adjustments. Includes audit logging for destructive writes so you can diff and reverse template changes. Requires a master API key for access to the emailer campaign and analytics endpoints. Start with apollo_campaign_health for a daily digest across sequences and mailboxes, then use apollo_sequence_add_contacts and apollo_template_update to manage campaigns without touching the Apollo UI. Handles rate limits and Cloudflare fingerprinting transparently.
