Instantly.ai

Instantly.ai is a cold email infrastructure platform for agencies and sales teams running high-volume outbound. Its core technical focus is deliverability at scale. Every plan includes unlimited email accounts and automated warmup, and the Light Speed plan adds SISR (Server and IP Sharding and Rotation), which assigns dedicated IP blocks per sending domain and swaps flagged IPs to protect sender reputation. Sending across many client domains without hand-managing deliverability is the primary use case. The agentic layer is the AI Reply Agent and sequence automation. Once prospects are enrolled, Instantly sends, waits, and follows up on no-reply behavior, and routes every inbound reply through the AI Reply Agent, which classifies by intent and triggers the matching follow-up automatically. Interested replies can be flagged, routed to a priority Unibox inbox, or fire a CRM task. No per-reply human approval is required once campaigns are running. AI Workflows handle lead routing, tagging, and campaign triggers. Integration depth is solid, with one caveat. Native connectors cover HubSpot, Pipedrive, Clay, Calendly, HighLevel, and RB2B, alongside Slack webhooks and a full REST API v2 with OAuth and scoped keys. Salesforce is supported through OutboundSync rather than a native connector. Zapier, Make.com, n8n, and Pabbly cover the long tail. Instantly publishes an official MCP server at mcp.instantly.ai, documented with connection steps for Claude Desktop, Cursor, n8n, and any MCP-compatible client, so campaigns, leads and analytics can be driven in natural language. The caveat is that Instantly states its HubSpot and Salesforce sync is one-way: its July 2026 integration note describes logging sent emails, replies, and lead status changes from Instantly into the CRM, not reading back from it. Governed two-way sync requires OutboundSync, a paid partner tool, or a hand-built Zapier or Make.com flow. Pricing is modular, with separate subscriptions for Outreach (sending infrastructure) and Instantly Credits (the 450M+ lead database). Outreach: Growth $47/month, Hypergrowth $97/month, Light Speed $358/month, or $37.60, $77.60, and $286.30 billed annually. Credits: Growth $47/month, Supersonic $97/month, Hyper Credits from $197/month, or $37.60, $87.30, and $177.30 billed annually. Enterprise is quote-only on both, and a VIP managed services tier is custom priced. Buyers who need lead sourcing as well as sending run both subscriptions together, an entry of $94/month, or $75.20 billed annually, which is also what the AI Sales Agent requires. The $47 headline covers sending only. On Growth the Unibox reply inbox is preview-only and webhooks start at Hypergrowth, and once a plan's included volume is used, buyers move up a tier rather than paying an overage charge. Credits are consumed as well as subscribed to, which is the part modular pricing hides. The AI Sales Agent draws 5 Instantly Credits per lead, against a Growth allowance of 1,500 to 2,000 credits per month, so the entry tier funds a fixed volume of sourcing rather than unlimited use. The AI Reply Agent draws the same 5 credits for every reply it writes, and unused credits expire two months after purchase on monthly plans, or a year on annual ones. A smaller Nano credits plan at $9 per month carries 150 credits. Plan for warmup before the first campaign goes out. Instantly's own guidance is to keep new accounts to roughly 10 warmup emails per day, to configure MX, SPF, DKIM and DMARC first, and to wait at least two weeks before using an account for campaigns. Accounts can be connected and a campaign built in minutes, but sender reputation is the gating factor on when it should actually send. Instantly also sells pre-warmed Google accounts at $10 a month, ready to send from day one, alongside done-for-you accounts from $4 a month and domains at $15 a year. On security, Instantly publishes a Data Processing Addendum covering GDPR and CCPA, names EDPO as its EU representative under the GDPR, and carries a dedicated CCPA privacy notice, but it holds no public SOC 2 Type II certificate. Instantly says so itself, writing that SOC 2 and ISO 27001 are not publicly claimed, and points buyers who require certification to request attestation reports under NDA. There is no security or trust page on the site and no trust portal on any subdomain. Instantly is built around cold email. Teams that want LinkedIn, calling, SMS and WhatsApp steps in one sequence builder can compare lemlist ($55/mo billed annually). Apollo.io ($49/mo billed annually) bundles a contact database, sequencing, dialer, and CRM into a single subscription. Clay ($54/mo billed annually) suits teams that want to control enrichment waterfalls and personalization prompts directly. Current state Q3 2026: the Instantly MCP Server is live and documented at mcp.instantly.ai. AI Workflows, the Web Researcher Agent, the AI Email Writer Agent, bring-your-own-key access to five major LLMs, and a VIP managed services tier are all shipped. The AI Sales Agent runs on the combined Outreach and Instantly Credits subscriptions, an entry of $94/month, or $75.20 billed annually, and Instantly also documents combined Scale and Agency bundles. Outreach carries a 14-day trial with no card required. Instantly holds no public SOC 2 Type II certificate as of its own published statement, and its Data Processing Addendum was last updated September 2026.
