FAQ
What is bulk email validation?
Bulk email validation is the process of checking a list of addresses before using it in campaigns, CRM updates, enrichment jobs, or outbound systems. The goal is to reduce bounces, identify risky addresses, and produce fields that downstream tools can segment or suppress.
What signals are useful in a bulk result file?
Useful bulk output includes normalized email, status, score, reason, domain, MX data, disposable flag, role flag, accept-all behavior, and other provider or mailbox signals. These fields let teams build review and suppression rules instead of relying on one pass/fail column.
Can bulk validation detect disposable emails?
Yes. Disposable email detection is included as a separate signal, which is useful for signup cleanup, lead quality checks, fraud controls, and suppression policies.
Can bulk validation check MX records?
Yes. MX checks help identify domains without valid mail routing and provide context for mailbox-oriented checks. They are especially useful when cleaning older lists where domains may have changed ownership or stopped receiving mail.
Should bulk validation delete records automatically?
Usually no. A safer workflow is to tag records with status and reason fields, then let the sending, CRM, or compliance system decide whether to suppress, review, retry, or keep each record.
Do bulk validation credits expire?
No. Credits do not expire and are shared across bulk validation, API checks, and single-address verification.
How should teams interpret accuracy for bulk lists?
Accuracy should be interpreted as a practical deliverability signal, not an absolute future guarantee. Bulk lists often contain catch-all domains, temporary provider failures, and stale records, so review queues and reason codes are important for high-volume operations.
