API access starts on the Growth plan. 2. Agency accounts: Agency Dashboard -> Settings -> General -> Create API key. Team accounts: Settings -> Integrations -> API keys. API access must be enabled on the plan. 3. Send it with every request: header (Authorization: , NO 'Bearer ' prefix). 4. Make a first call: Agency for the current API key. Keep the key in an environment variable, never in the command. ``` curl -X POST "https://api.quickmail.com/v2/graphql query agency" \ -H "Authorization: $QUICKMAIL_API_KEY" \ -H "Content-Type: application/json" \ -d '{}' ``` ## Where the docs live What Where Documentation [api.quickmail.com/help](https://api.quickmail.com/help) API reference [api.quickmail.com/help](https://api.quickmail.com/help) Base URL `https://api.quickmail.com` MCP server `https://api.quickmail.com/mcp` ## Strengths and limits ### Where it fits - Agencies wanting org-wide webhooks across client workspaces (Agency plan) - Teams that want unlimited users, email senders and LinkedIn accounts at a flat price - Combined email + LinkedIn steps built by API (connection, InMail, message, profile-visit steps) - Per-mailbox deliverability control via API (daily limit, Deliverability AI threshold, recovery period) ### Where it falls short - Starter-plan accounts: no API, no MCP - High-throughput integrations: 10 requests per 10 seconds - Event webhooks below the $299 Agency plan - REST-only stacks: it is GraphQL only ### Worth knowing - Authorization header takes the RAW key; adding 'Bearer ' breaks auth. - Rate limit is only 10 requests per 10 seconds per agency, and MCP calls draw on the same organization limit. - No API and no MCP on Starter ($49); API starts at Growth ($99). - Event webhooks are Agency-plan only ($299/mo); Growth must poll or use in-campaign webhook steps. - When plainText is true in an email mutation, openTracking and clickTracking must be false. 7 moreShow fewer - Creating a LinkedIn connection or InMail step silently creates a profile-visit step before it. - Stats: attributionType 'journey' counts a lead contacted on both channels twice; profile visits are not backfilled before tracking was enabled. - IDs are prefixed opaque strings (e.g. cmp\_xxx); use exactly what the API returns. - Webhook requests carry no signing secret, HMAC or token; add your own secret query parameter to the endpoint URL to verify them. - The help article's Ruby samples post to `https://api.quickmail.com/api/v2/graphql`, but the API reference endpoint is `https://api.quickmail.com/v2/graphql`; use the reference URL. - Trial accounts are capped at 100 imported leads and 100 emails per day, so a trial cannot run a full campaign. - Salesforce is connected by BCC logging only; native 2-way CRM sync is HubSpot and Pipedrive. ## Who should use it Use QuickMail for Agencies wanting org-wide webhooks across client workspaces (Agency plan) Look elsewhere for Starter-plan accounts: no API, no MCP ## If QuickMail is not the answer Other Email sending tools in this directory, each with its own review.

Free tier: 14-day free trial with all features, limited to 100 imported leads and 100 emails per day. - **Keep the key out of your code**API key. It is sent as: header (Authorization: , NO 'Bearer ' prefix). - **Design around the rate limit**10 requests per 10 seconds, enforced per agency (MCP shares the same organization limit); X-RateLimit-Limit/Remaining/Reset (ISO8601) headers on every response; HTTP 429 when exceeded. - **Know the catch before you scale**Authorization header takes the RAW key; adding 'Bearer ' breaks auth. ## Want us to build it for you?
