Monthly and annual billing are shown apart. ### Base Plan $599/mo billed monthly 500,000 emails per month; unlimited leads, workspaces and teammates; isolated network with dedicated IPs; warmup; API; private Slack support API includedPlan details buy additional monthly send buckets (price not published) ## Rate limits Limits apply per API key; numbers are not published. More on limitsLess Exceeding them returns 429 {"error":"rate\_limited","retry\_after":}; retry after the window indicated by headers. Neither the docs nor the OpenAPI spec give figures. Paginated list endpoints return 15 records per page (data/links/meta). ## How to get an API key EmailBison uses API key. The steps below follow EmailBison's own docs. 1. Create a EmailBison account. API access starts on the Base Plan plan. 2. Settings -> Developer API -> New API Token. 'api-user' tokens are scoped to the workspace they were created in (recommended). 'super-admin' tokens impersonate their creator and follow that user's current workspace. 3. Send it with every request: header (Authorization: Bearer ). 4. Make a first call: Account Details, This endpoint retrieves the details of the authenticated user. The user must provide a valid authentication token in the request header to access this endpoint. Keep the key in an environment variable, never in the command. ``` curl -X GET "https://send/api/users" \ -H "Authorization: Bearer $EMAILBISON_API_KEY" ``` ## Where the docs live What Where Documentation [docs.emailbison.com/get-started/introduction](https://docs.emailbison.com/get-started/introduction) API reference [dedi.emailbison.com/api/reference](https://dedi.emailbison.com/api/reference) OpenAPI spec [dedi.emailbison.com/api/reference.openapi](https://dedi.emailbison.com/api/reference.openapi) llms.txt [docs.emailbison.com/llms.txt](https://docs.emailbison.com/llms.txt) Base URL `https://send` ## Strengths and limits ### Where it fits - Agencies and teams sending hundreds of thousands of emails a month that want dedicated IPs and no per-seat or per-lead fees - Multi-workspace (multi-client) builds driven by API: create workspaces, users and api-user tokens per workspace - Clay-driven pipelines (documented Clay HTTP recipes for find/create lead, import to campaign, blocklist) - Webhook-driven reply handling with replayable event history (10 days) ### Where it falls short - Small senders: the entry price is $599/mo for 500k emails - LinkedIn outreach (pair with HeyReach, which has a native EmailBison step) - Anyone who needs documented API rate-limit numbers (the developers page says limits apply per key and returns 429 with retry\_after, but publishes no figures) ### Worth knowing - There is no single API host: every customer has its own instance, and the base URL is whatever domain you log in on. Docs examples use dedi.emailbison.com. - The OpenAPI spec linked from llms.txt (docs.emailbison.com/api-reference/openapi.json) returns 404. The real spec is the Scalar data-url at /api/reference.openapi. - super-admin tokens follow the creating user's CURRENT workspace, so a script can silently start writing into another client's workspace when that user switches. Use per-workspace api-user tokens. - Bulk lead creation silently skips personal-domain addresses (gmail.com etc.) unless support enables them on your instance. - Leads attached to an active campaign are cached and synced every 5 minutes, so a read-back straight after the call can look incomplete. 5 moreShow fewer - List endpoints page at 15 records, so a full export needs many calls; rate limits are per key but no figures are published, so throttle and honour 429 retry\_after. - SSO (SAML) and SCIM exist, but SCIM requires an enterprise plan. - The extra-send-bucket price above 500k/month is not published. - HubSpot and Salesforce sync are 'Powered by OutboundSync' (a third-party connector), not a native EmailBison integration. - The endpoint list on the marketing developers page does not match the OpenAPI spec (e.g. it shows POST /api/campaigns/{id}/pause and POST /api/webhooks; the spec has PATCH /api/campaigns/{campaign\_id}/pause and /api/webhook-url). Build from the spec. ## Who should use it Use EmailBison for Agencies and teams sending hundreds of thousands of emails a month that want dedicated IPs and no per-seat or per-lead fees Look elsewhere for Small senders: the entry price is $599/mo for 500k emails ## If EmailBison is not the answer Other Email sending tools in this directory, each with its own review.

It is sent as: header (Authorization: Bearer ). - **Design around the rate limit**Limits apply per API key; numbers are not published. - **Know the catch before you scale**There is no single API host: every customer has its own instance, and the base URL is whatever domain you log in on.
