What is a bounce?

A bounce occurs when an email cannot be delivered. Our email verification process helps prevent bounces by checking the validity of your email list before sending. This helps protect your sender reputation.

Does Minelead free email verifier send test emails?

No, we do not send any test emails to validate an email address. Minelead’s email verification system operates in full stealth mode, ensuring complete privacy and discretion for our users.

What is Sender Reputation?

Sender reputation is the email's domain and IP reputation score that email service providers use to decide if your emails should reach the inbox or end up in the junk. Sender repution is affected by factors like bounce rates, spam reports, and sending practices. A poor sender reputation can lead to getting blocked by email servers or your email getting marked as spam. Regular email validation using an email verification tool like Minelead can help maintain a high sender reputation score by preventing sending emails to invalid addresses.

How does Minelead email verifier work?

Minelead performs a comprehensive 4-step verification process: 1) Syntax check to validate format of the email, 2) Domain verification to ensure the MX records and email server exist, 3) SMTP verification to check server response for each particular email, and 4) Deep-level mailbox verification to confirm the address actually exist. All these 4 steps happen in real-time without sending any test emails to the email address being verified and the data from all steps are taken into account to assess the validity of each and every email address.

Why is email validation important for marketing campaigns?

Email validation is an important step before sending any email marketing campaigns for several reasons: 1) Email list validation reduces bounce rates that has direct effect on damaging sender reputation, 2) Email addresses change, therefore, regular validation of your email lists help maintain your list hygiene and improve its deliverability, 3) Email verification increases your marketing campaign ROI by ensuring emails reach real recipients with valid email addresses, and 4) Email validation protects your IP and domain reputation from being blacklisted due to sending to many invalid addresses.

What does 'catch-all' mean?

A catch-all or accept-all email server accepts all incoming emails regardless of whether the specific email address to which the email is being sent to actually exists or not. While the email format is valid, the MX records exist the SMTP check is successful, still the email address could be invalid if the mail server is a catch-all or accept-all one. Minelead's advanced email verification system checks and identifies catch-all servers and take it into account when assessing validation of an email address.
