Detailed Insights

Understand the status of each address with a transparent result: the syntax, the domain and its MX records, whether the mailbox accepts mail, and whether the address is disposable, role-based, or a catch-all.

Whole Lists, Paid per Result

Create an account to verify a whole list at once. You see what the file holds before any credit is used, and only definitive results are charged.

Six Checks Per Address

Syntax, MX records, a live SMTP probe, the disposable-provider list, role-based patterns (info@, support@…) and catch-all detection, with one plain answer on whether to send.

What Does Our Email Verifier Check?

  1. 01

    Syntax Check

    Validates the email's structure against standard formatting rules (e.g., name@domain.com). In a list, a likely typo such as name@gmial.com gets a suggested correction.

  2. 02

    Mailbox Validation

    Asks the recipient's mail server whether the mailbox exists, without sending an email, and reports a mailbox that is full or disabled.

  3. 03

    Role-Based Email Identification

    Recognizes generic or non-personal emails (e.g., info@domain.com, support@domain.com), which might not be ideal for personalized email campaigns.

  4. 04

    Domain Verification

    Confirms that the domain exists and has MX (Mail Exchange) records, so it can receive email. When a domain takes no mail, every address on it is undeliverable.

  5. 05

    Disposable Email Detection

    Identifies temporary or one-time-use email addresses often created for spam or short-term purposes.

  6. 06

    Catch-All Detection

    Detects domains configured to accept all emails regardless of validity.

Frequently Asked Questions

Common questions about address verification, bounce risk, and what the tool catches.

What is an email verifier, and what does it check?
An email verifier is a tool that validates the accuracy of email addresses. It performs technical checks like syntax validation, domain verification, and mailbox existence, ensuring that the email address can receive messages. Additionally, it flags disposable, role-based, and catch-all addresses, which can accept mail but are riskier to send to.
How does the mailbox validation work?
Mailbox validation involves safely interacting with the recipient’s mail server using SMTP commands. This process confirms whether the email address exists and can receive emails, all without sending an actual message. It’s a secure and non-intrusive method of ensuring accuracy.
What is a catch-all email address, and why does it matter?
A catch-all email address is configured to accept any emails sent to its domain, regardless of whether the specific recipient exists. While this may seem beneficial, it can lead to higher bounce rates and less reliable communication. Our tool detects catch-all domains and flags them as “Risky.”
How does your tool detect disposable emails?
Our email verifier checks the address’s domain against a maintained list of known disposable and temporary email providers. It does not flag spam traps: their operators keep them private, and a trap accepts mail like any ordinary mailbox, so no SMTP check can tell one apart.
Can I verify a whole email list?
Yes. With an account, upload a CSV or TXT file exported from your email platform or CRM. Before any credit is used, the file is read and you see how many addresses are duplicates, malformed, disposable or likely typos. Every other column in your file is kept, so each result stays next to the contact it belongs to.
How much does it cost to verify a list?
Each unique address with a definitive result (deliverable, risky or undeliverable) uses 1 credit. Duplicates, malformed addresses and unknown results are not charged, and you see the number of credits before you start. Verifications come with the Custom plan, and you can top up credits without changing plan.
What do I get back after a list is verified?
Every address gets a status (deliverable, risky, undeliverable or unknown), the reason behind it and what to do: keep, review, remove or retry later. Download the addresses ready to send, a suppression list, or every row of your file with result columns added, as CSV or as an Excel file with colored results and filters.
Is my email data safe, and how long do you keep it?
Yes. The address travels over an encrypted connection and is checked on our own servers, not through a third-party verification service. We handle it under the GDPR and never sell or share it. Each address you check is stored with its result for 30 days, then deleted automatically.
