FAQs
-
How does email verification improve deliverability?
Email verification removes invalid, disposable, and risky addresses from your list before sending. This reduces bounce rates, protects your sender reputation, improves inbox placement, and can increase email deliverability by 20-40% on average. -
What is the difference between a Hard Bounce and a Soft Bounce?
A Hard Bounce indicates a permanent error, meaning the email address does not exist, the domain is invalid, or the recipient server has blocked delivery. A Soft Bounce is a temporary issue, often caused by a full mailbox, server downtime, or a message that is too large. -
What is a 'Catch-All' or 'Accept-All' email server?
A 'Catch-All' server is configured to accept all emails sent to a specific domain, regardless of whether the specific mailbox exists. These are risky for marketers because they can skew deliverability metrics. Bulk Email Checker identifies these domains so you can decide whether to segment them or verify them further. -
Can you detect 'Spam Traps' and 'Honeypots'?
Yes. Spam traps are secret email addresses created by Internet Service Providers (ISPs) and anti-spam organizations to catch senders with poor list hygiene. Our system cross-references your list against a massive database of known spam traps and honeypots to remove these toxic threats. -
What are 'Disposable' or 'Burner' email addresses?
Disposable emails (also known as 'burner' or 'temporary' emails) are short-term addresses created by users to bypass registration forms without providing their real contact info. We automatically detect and flag these domains so you can block fake signups and keep your database high-quality.
