Emailable MCP by usefulapi

SPENDS CREDITS: starts a bulk verification of up to 5000 email addresses. Emailable takes 1 credit per email when the batch is created, and if the account has too few credits it may charge the account's saved card to buy more. A test_ API key spends nothing. The batch cannot be cancelled here, and the call is never retried: if it fails or times out, check emailable_get_account before trying again, because a retry can charge twice. Returns the batch id; poll it with emailable_get_batch. Emailable's terms allow verification of opt-in subscribers' addresses. POST /v1/batch.

The Emailable account behind this API key: the owner's email and available_credits. Check it before a large batch. GET /v1/account.

Status and results of a batch made with emailable_create_batch: message, progress (processed/total), reason_counts and total_counts (deliverable, undeliverable, risky, unknown). Batches of up to 1,000 emails also return the results inline in emails (30 days). They come in pages: up to limit results, fewer if the reply would get too long; ask for the next page with emails_page.next_offset. A bigger batch returns download_file, a temporary link (5 days) to a ZIP of a CSV: share it only with the account owner. Free to call. GET /v1/batch.

SPENDS CREDITS: verifies one email address and uses 1 Emailable credit (a test_ API key spends none). Returns state (deliverable, undeliverable, risky, unknown), reason, score (0-100), and flags: disposable, free, role, accept_all, no_reply, mailbox_full, plus did_you_mean (a typo fix), the detected user/domain/tag, mx_record and smtp_provider. A credit is returned for an unknown result. The call is never retried automatically. If the reply is {status: "try_again"}, the check took longer than the timeout: call again with the same email; repeats within 5 minutes are not charged. Emailable's terms allow verification of opt-in subscribers' addresses. GET /v1/verify.
