More on limitsLess Several endpoints have stricter limits (emails list 20/min, test email 10/min, OAuth init 75/min/workspace). Our trial calls returned no rate-limit headers on any response, so you cannot read the remaining budget from headers. ## How to get an API key Instantly uses API key. The steps below follow Instantly's own docs. 1. Create a Instantly account. API access starts on the Outreach Growth plan. 2. Settings -> Integrations -> API Keys (Version 2) -> Create API Key: name + scopes (the in-app picker listed 128 scopes, all:\* and per-resource:all/:create/:read/:update/:delete; scopes cannot be changed after creation). Shown once, unrecoverable (GET /api/v2/api-keys returns key: ""). v2 keys differ from v1 keys. 3. Send it with every request: header: Authorization: Bearer . 4. Make a first call: Get campaigns associated with an email, Requires one of the following scopes: `account_campaign_mappings:read`, `account_campaign_mappings:all`, `all:read`, `all:all`. Keep the key in an environment variable, never in the command. ``` curl -X GET "https://api.instantly.ai/api/v2/account-campaign-mappings/{email}" \ -H "Authorization: Bearer $INSTANTLY_API_KEY" ``` ## Where the docs live What Where Documentation [developer.instantly.ai/index.md](https://developer.instantly.ai/index.md) API reference [developer.instantly.ai/api-reference/introduction.md](https://developer.instantly.ai/api-reference/introduction.md) OpenAPI spec [api.instantly.ai/openapi/api\_v2.json](https://api.instantly.ai/openapi/api_v2.json) llms.txt [developer.instantly.ai/llms.txt](https://developer.instantly.ai/llms.txt) Changelog [feedback.instantly.ai/changelog](https://feedback.instantly.ai/changelog) Base URL `https://api.instantly.ai` MCP server `https://mcp.instantly.ai/mcp` SDKs @instantlyai/sdk (TypeScript, beta, Node 22+), @instantlyai/cli (npm, includes local MCP via \`instantly mcp\`) ## Strengths and limits ### Where it fits - Cheapest entry to API-driven cold email: API v2 is on every paid Outreach plan from Growth ($47/mo), and in our test it also worked on the 14-day free trial - Agents and LLM tooling: hosted MCP at mcp.instantly.ai (199 tools in tools/list on 2026-10-25; docs say 'every v2 endpoint'), plus an npm CLI with a local MCP - Least-privilege integrations: per-key scopes (e.g. campaigns:read, leads:all) - Programmatic mailbox provisioning: OAuth connect flows and done-for-you account/domain orders via API ### Where it falls short - Webhook-driven reply capture on the Growth plan: help center and pricing gate webhooks to Hypergrowth ($97/mo) and above (the Webhooks tab still shows 'Add Webhook' on the free trial; creating one was not tested) - Reselling or building data products from enriched/visitor data: the terms ban any 'Data Resale Activity' - Polling the email/inbox list heavily: GET /api/v2/emails is capped at 20 requests/minute ### Worth knowing - API v1 was deprecated on 19 Jan 2026; v2 needs a NEW key, v1 keys do not work on v2. - Help center and pricing say API is on every paid plan but not on the free trial; in our 2026-10-25 trial, API keys and v2 calls worked on plan pid\_free. Webhooks and Slack are gated to Hypergrowth ($97/mo) in the docs. - Rate limit is per WORKSPACE, shared across all keys and across v1+v2, so a Zapier zap on v1 eats your v2 budget. - GET /api/v2/emails (reply/inbox polling) is limited to 20 req/min, far below the 6,000/min headline. - Credits are a SEPARATE subscription from Outreach; unused credits expire after 2 months on monthly plans, 1 year on annual. 10 moreShow fewer - No overage billing: hitting the email or uploaded-contact cap means upgrading or buying the $87 add-on, which only exists on Hypergrowth and above. - Webhooks auto-disable on delivery failures (status -1) with no published retry schedule; watch the status field and use the resume endpoint. - Terms prohibit any Data Resale Activity, including data enriched or verified through Instantly. - Custom reply labels are sent as the webhook event\_type verbatim, so a receiver keyed on fixed event names will miss them. - API key is shown once and cannot be recovered. - Webhook event names in the developer guide are wrong for the API: use email\_link\_clicked (not link\_clicked); auto\_reply\_received is not in the spec enum or the live event list. - MCP header auth returned 504 in our 2026-10-25 test while the URL-path key worked; if header auth fails, it is the server, not your key. - Bundle prices on the public pricing page (Scale $194, Agency $555) do not match the in-app Bundles tab (Scale $294/$265 annual with 10k credits, Agency $858/$772 with 45k credits); check the app before quoting. - No rate-limit headers are returned, so throttle client-side to 100 req/s and 6,000 req/min per workspace. - Campaigns now live under 'Engage' (/app/engage) in the app; clicking 'Cold Outreach Campaign' immediately creates a Draft campaign. ## Who should use it Use Instantly for Cheapest entry to API-driven cold email: API v2 is on every paid Outreach plan from Growth ($47/mo), and in our test it also worked on the 14-day free trial Look elsewhere for Webhook-driven reply capture on the Growth plan: help center and pricing gate webhooks to Hypergrowth ($97/mo) and above (the Webhooks tab still shows 'Add Webhook' on the free trial; creating one was not tested) ## If Instantly is not the answer Other Email sending tools in this directory, each with its own review.

Free tier: 14-day free trial, no card. - **Keep the key out of your code**API key. It is sent as: header: Authorization: Bearer . - **Design around the rate limit**Shared by API v1 and v2 across the whole workspace, even with multiple keys: max 100 requests/second and 6,000 requests/minute; exceeding either returns 429. - **Know the catch before you scale**API v1 was deprecated on 19 Jan 2026; v2 needs a NEW key, v1 keys do not work on v2. ## Want us to build it for you?
