Apollo.io vs Instantly.ai (2026)

Apollo.io

by Apollo

Instantly.ai

by Instantly

Pros

• ✓240M+ verified contacts and 30M+ companies with the most complete filter set in the category: funding stage, technographics, hiring signals, intent data, job change alerts, and AI-powered Lookalikes (BETA). All accessible without a separate data provider.
• ✓Autonomous sequence execution runs outreach end-to-end once configured: Apollo sends, waits, follows up, and logs to CRM without per-step human approval. AI Assistant (introductory free on paid plans) provides conversational access to prospecting data and campaign analysis.
• ✓Publishes a first-party remote MCP server at mcp.apollo.io with OAuth and prebuilt connectors for Claude, ChatGPT, and Perplexity, available on every plan including the free one, plus action-level CRM writes to Salesforce and HubSpot.

Limitations

• ⚠Credit-based pricing creates budget unpredictability. Credits are granted upfront on annual plans and additional credits cost extra, with a verified email costing 1 credit, a phone number 8 credits, data enrichment 1 to 8 credits per record, and US dialing 2 credits per minute.
• ⚠API access is gated behind Professional ($79/user/mo) or the sales-gated Custom plan, so teams on Basic cannot build automated workflows or agent integrations, making the $49 entry price misleading for technical buyers who need programmatic access.
• ⚠Organization requires a minimum of 3 seats at $119/user/mo. Downgrades take effect immediately with no mid-term refunds, so teams that shrink pay for the remainder of their billing cycle on unused capacity.
• ⚠Apollo's AI policy states that Apollo may use Customer Data as an input to train its own internal models, and publishes no customer opt-out. The only opt-out offered is profile suppression for individuals in Apollo's contributor database, which is a data-subject right rather than a customer control.

Pros

• ✓Deliverability infrastructure is the strongest in the category. Unlimited accounts on every plan, automated warmup, and SISR dedicated IP rotation keep mail out of spam at volume.
• ✓The AI Reply Agent classifies inbound replies by intent and triggers the correct follow-up automatically, so high-volume outbound runs without a human triaging every reply.
• ✓Publishes an official first-party MCP server at mcp.instantly.ai alongside a full REST API v2 with OAuth, so campaign management can be driven from Claude or from custom tooling.

Limitations

• ⚠Modular pricing understates the real cost. Outreach and Credits are separate subscriptions, so sending plus lead sourcing starts at $94/month, or $75.20 billed annually, not the advertised $47.
• ⚠CRM sync is one-way. Instantly states that its HubSpot and Salesforce connectors push activity and reply logs out of Instantly but do not sync back. Two-way sync into CRM objects needs OutboundSync, a paid partner tool, or a hand-built Zapier or Make flow.
• ⚠No public SOC 2 Type II certificate. Instantly states this itself and directs buyers needing certification to request attestation reports under NDA. GDPR and CCPA are covered by a published DPA.
• ⚠New sending accounts are not usable immediately. Instantly advises keeping them to about 10 warmup emails per day, configuring MX, SPF, DKIM and DMARC, and waiting at least two weeks before running campaigns on them.
