Email validation

Verify email addresses

Queue an SMTP mailbox probe for lead addresses, raw addresses, or both. Results are written back onto the leads as email_status, email_provider, email_is_role and email_validated_at.

Pass estimate_only to price the run without queueing it. You are only charged for probes that actually run — cached results and addresses rejected by the cheap pre-check are free.

Requires the leads:validate permission, deliberately separate from write so a general-purpose key cannot run up a validation bill.

Authorizations

Authorization

string

header

required

A ManyPI API key (mpi_...) from Settings → API keys, or an OAuth 2.1 access token obtained through the MCP consent flow.

Body

application/json

lead_ids

string<uuid>[]

Leads in this workspace whose addresses should be checked.

emails

string[]

Raw addresses, not tied to a lead.

estimate_only

boolean

Price the run without queueing it.

Response

The job was queued, or (with estimate_only) priced.

Two shapes. A normal call queues a job and returns job_id, total and estimate. An estimate_only call queues nothing and returns estimate alone — with no job_id and no total — so test for job_id before treating the response as a queued job.

job_id

string<uuid>

Absent when estimate_only was set.

total

integer

Absent when estimate_only was set.

estimate

object

Always present.
