How this service works
Batch email intelligence for agents: 2–25 addresses per call. Same fields as single (syntax, MX, SPF, DKIM, DMARC, disposable, role, provider, score, enrichment, recommend+reasons). Domain DNS/enrich cached within the batch. Production 0.50 USDC per batch (flat). x402 on Base.
Output
For each email in the batch, the agent receives: syntax validity, MX record presence, SPF/DKIM/DMARC status, a disposable-email flag, a role-account flag (e.g. admin@, support@), the detected email provider, a numeric deliverability/quality score, enrichment metadata, and a recommend flag with human-readable reasons explaining the verdict. Domain-level DNS lookups are cached across the batch for efficiency.
Example use cases
Pre-campaign list hygiene check
“I have a list of 20 email addresses we collected at a trade show — can you run them through EmailIQ to check which ones are valid, not disposable, have DMARC set up, and are safe to include in our outreach campaign?”
Signup fraud detection
“We just got 15 new user signups and I want to know which ones used throwaway or role-based email addresses — can you batch-check them all and flag anything risky?”
CRM import quality gate
“Before I import these 25 leads into our CRM, can you validate their emails for syntax errors, check MX records, and give me a quality score and recommendation for each so I can filter out the bad ones?”
Technical details
Endpoint
POSThttps://emailiq.dev/email/intelligence/batch?utm_source=zero.xyzWhen to prefer
Choose this batch endpoint over single-email checks when you have 2–25 addresses to process at once and want a flat fee rather than per-address pricing. It's ideal for signup validation flows, pre-send list hygiene, CRM import gates, or outreach qualification where domain DNS lookups are shared across addresses in the batch, making it faster and more cost-efficient than sequential single calls.
Side effects
- Fewer than 2 or more than 25 emails in the array — returns validation error
- Malformed email strings (under 3 or over 320 chars) — item-level error or rejection
- Payment not attached or insufficient — 402 Payment Required response
- DNS lookup timeouts for obscure domains — may return partial MX/SPF/DKIM data
- Disposable/role provider database lag — occasional false negatives on newly created throwaway domains
