An agent plans and launches campaigns, finds and imports leads from the contact database, connects SMTP and IMAP sender emails and tracks their warm-up and DNS health, verifies email lists, and reads inbox-placement and deliverability insights. It also runs autopilot campaigns with approval gates and manages ideal customer profiles, credits, and workspace members. ## For AI agents Automate cold email outreach: build and run campaigns and sequences, source and import leads, connect and warm up sender emails, verify lists, read deliverability insights, and handle replies and AI reply drafts. ## Scope Does not run paid ads, send SMS, or host a sales CRM pipeline. Use for cold email outreach, deliverability, and lead sourcing only. ## Capabilities - Build and run cold email campaigns with multi-step sequences and schedules - Find leads in the contact database and import them into a campaign - Connect SMTP and IMAP sender emails and track their warm-up and DNS health - Verify email lists and read inbox-placement and deliverability insights - Work with leads, replies, and AI reply drafts across a workspace - Run autopilot campaigns with approval gates and register webhooks ## Use cases ### Agent-run cold outreach campaign An agent plans a campaign from a website, launches it, attaches warmed-up sender emails, and sets the sending schedule, then monitors performance stats as replies come in. Each operation is discovered through Jentic by intent, so the agent goes from plan to live campaign without reading the reference docs. Example prompt: Plan a campaign from a website, launch it, attach a sender email, set the schedule, and read its stats ### Lead sourcing and verification Fill a campaign with qualified prospects by searching the contact database against an ideal customer profile, importing matches, and verifying their email addresses before sending. An agent can size the audience, import leads, and run a verification job to protect deliverability. Example prompt: Search the contact database for an ICP, import matching leads into a campaign, and verify their email addresses ### Deliverability monitoring Protect sending reputation by reading inbox-placement runs, sender reputation, and a sender email's DNS vitals and warm-up status. An agent can watch deliverability insights and pause sending when placement drops. Example prompt: Read inbox-placement insights and a sender email's DNS vitals, and pause a campaign if placement falls ### Reply handling Keep conversations moving by listing replies, reviewing a lead's conversation, editing an AI reply draft, and sending it. An agent can triage incoming replies and mark meetings as booked on the lead. Example prompt: List new replies, open a lead's conversation, edit the AI reply draft, send it, and mark a meeting booked ## Key endpoints | Method | Path | Description | | --- | --- | --- | | POST | `/campaigns` | Create a campaign | | GET | `/campaigns/{id}/stats` | Get campaign performance stats | | PUT | `/campaigns/{id}/sequence` | Replace a campaign's sequence | | POST | `/lead-finder/imports` | Import people from the contact database into a campaign | | POST | `/email-verification/jobs` | Verify a list of email addresses | | GET | `/replies` | List replies | | POST | `/sender-emails` | Connect an SMTP/IMAP sender email | | GET | `/inbox-placement/insights` | Read deliverability insights | ## Key resources - **Campaigns** — Create, run, schedule, and report on cold email campaigns and sequences - **Leads** — Create, update, and segment leads, and read their conversations - **Lead Finder** — Search the contact database and import people into a campaign - **Sender Emails** — Connect SMTP/IMAP senders and track warm-up and DNS health - **Email Verification** — Verify lists of email addresses and download results - **Inbox Placement** — Read placement runs, sender reputation, and deliverability insights ## AI readiness This API is usable in Jentic One now.

Through Jentic you install once, import the Emailchaser API from the API Directory, store the key once, and your agent calls it. - **Permission scoping:** Emailchaser puts the campaign id in the URL path (`/campaigns/{id}`), so a rule can pin your agent to one campaign and the operations you pick. You choose the operations it may call, so spending operations like buying credits or ordering domains are not included unless you add them. - **Credential handling:** Your Emailchaser key is stored once, encrypted, by your own Jentic One instance and injected at execution time. It never enters the agent's prompt, logs, or context. - **Discovery method:** Agents search Jentic by intent such as 'create a cold email campaign' or 'find leads for an ICP', and Jentic returns the matching Emailchaser operation with its input schema so the agent calls the right endpoint without browsing the reference docs. ## Related APIs - **Instantly** — Cold email sending and campaign automation - **Mailchimp** — Opt-in marketing email and audience management - **Apollo** — Prospect and contact data for list building ## FAQ ### What authentication does the Emailchaser API use? Per its OpenAPI spec, the Emailchaser API authenticates with a bearer API key, created per workspace, that is either read-only (read) or read and write (read_write). A small set of public marketing endpoints need no key. Through Jentic the key is stored encrypted by your own Jentic One instance and injected at execution time, so it never enters the agent's context. ### Can I create a cold email campaign with the Emailchaser API? Yes. The campaign operations create a campaign, set or replace its multi-step sequence, attach sender emails, set the schedule, and launch or pause it, and a stats operation reports performance as replies come in. ### What are the rate limits for the Emailchaser API? The OpenAPI spec does not state request rate limits; several operations instead gate on your credit balance and spend money when called. Check the Emailchaser documentation at https://www.emailchaser.com for current limits and credit costs. ### Is there an Emailchaser MCP server? You don't need an MCP server to give your agent the Emailchaser API. Jentic connects it directly from the API Directory: import it, store your key once, and your agent calls the campaign, lead, and deliverability operations it needs. ### Can I limit what my agent is allowed to do with the Emailchaser API? Yes. Because Emailchaser carries the campaign id in the URL path, you can pin a rule to one campaign and allow only the read and sequence operations, so the agent can run and report on that campaign. Spending operations such as buying credits or ordering domains are left out unless you add them, and every call the agent makes is logged. ### How do I launch a campaign through Jentic? Search Jentic for 'create a cold email campaign', and it returns the matching Emailchaser operations with their input schemas; your agent creates the campaign, sets its sequence, and launches it. To run it on your own infrastructure, install Jentic One from its GitHub repo.
