EmailIQ — Email Intelligence (MCP)

Instant email + domain intelligence for AI agents: syntax, MX, SPF, DKIM, DMARC, disposable detection, role accounts, provider, and a 0–100 score — via MCP tools.

Canonical path for agents (x402)

For agent commerce with x402 / USDC on Base (no Apify token), use the native host:

Surface	URL	Price
REST single	POST https://emailiq.dev/email/intelligence	0.10 USDC
REST batch	POST https://emailiq.dev/email/intelligence/batch	0.50 USDC flat (2–25)
Native MCP	https://emailiq.dev/mcp	same (tools analyze_email / analyze_email_batch)

This Apify Actor runs EmailIntelligence.analyze() in-process. It does not call https://emailiq.dev, and it has no x402 / wallet code. Billing here is Apify pay-per-event only, priced at parity with the site (not cheaper).

When to call

Persona	Scenario
Outbound / SDR agent	Before cold email, check that the address is syntactically valid, the domain accepts mail (MX), isn’t disposable, and the domain publishes SPF/DKIM/DMARC — then use the score as a gate.
Growth / list hygiene	Clean signup or CRM lists: drop role accounts (info@, support@), temp mailboxes, and low-score domains before a campaign.
Security / trust agent	Decide whether a contact or signup domain looks legitimate (auth records + provider) without running a full mailbox SMTP probe.

Example AI prompts

Copy-paste into Claude, Cursor, or any MCP client connected to this Actor (or to https://emailiq.dev/mcp):

1. Qualify before outreach
   Analyze the email jane.doe@acme.com with EmailIQ. Tell me if I should send a cold email: syntax, MX, SPF/DKIM/DMARC, disposable/role flags, provider, and score.

2. Filter a batch
   Run analyze_email_batch on these addresses and return only those with score ≥ 80 and is_disposable=false: a@gmail.com, b@mailinator.com, support@stripe.com

3. Domain trust check
   Check founder@startup.io — does the domain have SPF, DKIM, and DMARC? What’s the mail provider and delivery score?

MCP tools

analyze_email

Input	Type	Required	Price
email	string	yes	~$0.10 per successful call (email-analyzed)

analyze_email_batch

Input	Type	Required	Price
emails	string[] (2–25)	yes	~$0.50 flat per successful call (email-batch-analyzed)

Output fields (per email):

Field	Type
email	string
valid_syntax	boolean
domain_exists	boolean | null
mx_records	string[] | null
spf_enabled	boolean | null
dkim_enabled	boolean | null
dmarc_enabled	boolean | null
is_disposable	boolean | null
is_role_account	boolean | null
mail_provider	string | null
score	integer (0–100)
processing_time_ms	number

On emailiq.dev (REST + native MCP) each result also includes light domain enrichment and actionable recommend / reasons / bounce_risk.

Example output (single)

{
  "email": "someone@microsoft.com",
  "valid_syntax": true,
  "domain_exists": true,
  "mx_records": ["microsoft-com.mail.protection.outlook.com"],
  "spf_enabled": true,
  "dkim_enabled": true,
  "dmarc_enabled": true,
  "is_disposable": false,
  "is_role_account": false,
  "mail_provider": "microsoft",
  "score": 100,
  "processing_time_ms": 65.825
}

dkim_enabled is a presence check on common selectors (default, google, selector1, selector2, k1) at {selector}._domainkey.<domain> — not cryptographic signature validation (same spirit as spf_enabled / dmarc_enabled). Note: some providers (e.g. consumer Gmail) only publish date-rotated selectors outside this common set, so dkim_enabled may be false even when the domain signs mail.

How EmailIQ compares

Capability	Pure email validators	Pure domain / DNS checkers	EmailIQ
Syntax + disposable + role	Yes	Rarely	Yes
MX / domain exists	Sometimes	Yes	Yes
SPF + DKIM + DMARC	Rarely	Often SPF/DMARC only	Yes (all three)
Per-address delivery score (0–100)	Sometimes	No	Yes
MCP / AI-agent native	Rare	Rare	Yes
Pay per call (no SaaS seat)	Varies	Varies	~$0.10 / single · ~$0.50 / batch

EmailIQ combines mailbox-oriented signals (syntax, disposable, role, score) with domain auth intelligence (MX + SPF/DKIM/DMARC + provider) in one tool — so agents don’t stitch a validator and a DNS checker together.

Pricing (Apify PPE — parity with emailiq.dev)

Event	When	Price
email-analyzed	Once per successful analyze_email	$0.10 USD
email-batch-analyzed	Once per successful analyze_email_batch (2–25)	$0.50 USD

Configured in .actor/pay_per_event.json. Charged with Actor.charge(...). Must not undercut site x402 prices.

Connect (Standby MCP)

{
  "mcpServers": {
    "emailiq-apify": {
      "url": "https://marcelocarlos--emailiq-mcp.apify.actor/mcp",
      "headers": {
        "Authorization": "Bearer <YOUR_APIFY_API_TOKEN>"
      }
    }
  }
}

Prefer native (x402, no Apify token):

{
  "mcpServers": {
    "emailiq": {
      "url": "https://emailiq.dev/mcp"
    }
  }
}

Paid tool calls on the native host require an x402 PAYMENT-SIGNATURE header (same as REST).

Transport: Streamable HTTP (webServerMcpPath: /mcp).

Architecture notes

• Standby: one long-lived process serves many MCP requests until idle timeout; in-memory TTLCache (300s) is intentional and effective within that lifetime.
• aiodns: resolver is created lazily on the running asyncio loop; startup runs an early MX smoke test against gmail.com.
• Isolation: packaged under apify-actor/ so production EmailIQ (FastAPI + x402 + native /mcp) is untouched.
• Score: syntax 25 + domain 15 + MX 20 + SPF/DKIM/DMARC 10 each + not-disposable 5 + not-role 5 (capped at 100).

Status

Status: Live on Apify Store. Pay-per-event billing at parity with emailiq.dev ($0.10 single / $0.50 batch). Canonical agent discovery: https://emailiq.dev and MCP registry dev.emailiq/email-intelligence → https://emailiq.dev/mcp.
