Email list verification is the process of checking that every email address in your list is valid and deliverable, without sending an actual email to the address. This is essential for reducing bounce and spam complaint rates to maintain a high sender reputation and ensure that your messages stay out of the spam folder.

Accurate and Comprehensive Validation

Our six step process ensures that every email in your list is thoroughly validated and accurately categorised with a risk assesment. Our validation includes syntax, domain, and mailbox validation, as well as abuse and spam trap checks.

Protects Deliverability: Removing invalid email addresses, spam traps, and inactive subscribers improves your sender reputation and increases the likelihood of your emails reaching inboxes.

Higher Engagement Rates: A clean email list consists of active and interested subscribers, leading to higher open rates, click-through rates, and overall engagement with your email campaigns.

Improves Efficiency: Sending emails to invalid or inactive addresses wastes resources and increases email marketing costs. Cleaning your list ensures that you're only investing in reaching subscribers who are likely to engage with your content.

Syntax Check


In our syntax step, we check the email for proper format, looking for things like the @ symbol and correct domain structure. This ensures your list is free of errors and ready for the next steps in our validation process.

Abusive Address Check

We scan the address against our list of abusive domains to identify any emails associated with abuse and spam, disposable emails and Spam traps. You can ensure your email list is free from potentially harmful domains, boosting your sender reputation and improving deliverability.

Domain Record Check

We check the domain for an MX record, which is a DNS record that indicates whether the domain can receive emails. This ensures that the domain is valid and can receive emails, without it you could waste resources sending to an email that doesn't exist.

Email Server Check

We check the email server to ensure it exists and is a valid SMTP server capable of receiving emails. In this step we can test for spam traps and honeypots, ensuring your list is free from these harmful addresses.

Email Bounce Detection

Our service checks the server accepts the email address and can detect bounces without delievering any email. Scrubbing your list of these addresses reguarly can help you avoid bounces and improve your sender reputation.

Catch All Email Detection

While validating the email won't bounce we also check if the email is a catch-all address. These addresses are often used to collect emails and can be a sign of a low-quality list.
