Where Synter differs
AI Agent execution vs manual SDR seat management
Apollo is built around human SDR seats manually clicking through filters, enrollments, and dialers. Synter Prospector uses autonomous AI agents to research intent signals, enrich accounts, provision sending infrastructure, and execute outreach with human-in-the-loop review.
Outbound + ads unified across 43 advertising platforms
Apollo operates strictly as an email and dialer tool. Synter natively links outbound signals to 43 advertising platforms, providing 48-hour pre-targeting air cover before cold outreach and instant retargeting when leads engage.
Built-in domain isolation standard
Apollo frequently connects directly to corporate email inboxes, exposing root domains to deliverability penalties. Synter enforces dedicated secondary Porkbun sending domains with automated SPF, DKIM, and DMARC to guarantee primary domain safety.
What Apollo does well
- Extensive contact database and firmographic search filters
- Basic email sequencing and manual sales dialer workflows for SDRs
- Salesforce and HubSpot CRM bi-directional contact syncing
Pricing
Apollo offers public per-seat pricing tiers starting at $49/user/month (Basic) to $119+/user/month (Professional), plus additional export and enrichment credit add-on fees.
Synter publishes plans on its pricing page, covering agent execution, creative generation, and attribution.
FAQ
Is Synter an alternative to Apollo.io?
Yes. While Apollo is built for manual sales reps executing sequences from a static database, Synter Prospector is an AI agent executed system that combines live intent discovery, waterfall enrichment, dedicated secondary inboxes, and ad retargeting across 43 advertising platforms.
Why does Synter avoid per-seat pricing?
Synter is designed as an autonomous execution engine that replaces bloated SDR headcount and fragmented SaaS seat costs ($368k+/yr) with transparent subscription tiers: SOLO ($20/mo) and SCALE ($500/mo) with claimable monthly credits.
How does Synter protect brand email deliverability compared to Apollo?
Synter never sends outbound emails from your primary root domain. Dedicated secondary sending domains are automatically provisioned with full SPF, DKIM, and DMARC records and 301 redirection to keep inbox deliverability above 99.4%.
