Calculate your email list quality score to improve deliverability and protect your sender reputation.
Email verification is the process of validating email addresses to ensure they are active, properly formatted, and capable of receiving emails. This critical process helps marketers maintain clean email lists, improve deliverability rates, and protect their sender reputation.
The verification process typically checks multiple factors: syntax validation to ensure proper formatting, domain validation to confirm the domain exists and has valid MX records, mailbox verification to check if the specific address exists, and catch-all detection to identify domains that accept all email addresses.
A quality email list should have at least 95% valid addresses. Lists with high percentages of invalid addresses can damage sender reputation, trigger spam filters, and waste marketing resources on contacts who will never receive your messages.
Email addresses that are properly formatted, exist on active mail servers, and are ready to receive emails. These are safe to send to.
Email addresses that don't exist, have syntax errors, or belong to inactive domains. Remove these immediately to protect deliverability.
Domains configured to accept all email addresses. These may or may not be valid. Use caution when sending to catch-all addresses.
Excellent - premium quality list with maximum deliverability.
Good - acceptable quality but should clean invalid addresses.
Fair - needs cleaning to avoid deliverability issues.
Poor - high risk of bounces and reputation damage.
High bounce rates from invalid emails damage your sender reputation with ISPs. Email verification prevents bounces and maintains a positive sending history.
Clean lists lead to better inbox placement. ISPs favor senders with low bounce rates, increasing the likelihood your emails reach the primary inbox.
Stop paying to send emails to invalid addresses. Most email service providers charge based on list size, so removing invalid emails reduces costs.
Valid email lists naturally have better open and click rates because your emails reach real, active recipients who can engage with your content.
Sending to many invalid addresses can trigger spam traps and lead to blacklisting. Verification helps you avoid these hidden threats to your deliverability.
