Stop Bouncing Emails.
Start Hitting Inboxes.

Our syntax validator checks whether an email address is structured correctly before you use it. It quickly spots simple mistakes like a missing “@” symbol, extra spaces, or incorrect domain formats. It also flags unusual or invalid characters that could cause delivery failures. If someone types a common domain typo like “gamil.com” instead of “gmail.com” the system detects it and suggests the correct version, helping you improve accuracy and boost deliverability.

We verifies that the email domain is valid, active, and properly configured to receive messages by checking DNS settings. The system confirms that the domain exists, can route emails correctly, and has active MX records for reliable delivery. It also detects domains that accept mail through A records even if MX records are not explicitly configured, ensuring comprehensive validation.

This step evaluates catch-all domains that accept every email address, even invalid ones, flagging potential deliverability risks. The system also checks whether catch-all mailboxes are active. Analyses server response times during SMTP ping, where prolonged delays may signal spam traps or anti-abuse defences like SMTP tarpitting

Directly verifies with the mail server whether a mailbox exists by pinging SMTP server. Monitors server timeouts to avoid false negatives caused by slow responses. Analyses domain behaviour to detect differences between valid and invalid addresses, improving the precision of catch-all detection

Detects Secure Email Gateways that filter or block emails, helping identify delivery risks and ensuring more accurate validation results.

Detects spam trap addresses built to expose spammers, protecting your sender reputation and reducing blacklist risks. Identifies hidden honey traps that can silently harm deliverability. Monitors global blacklists to check if your domain or IP is flagged.

Detects role based addresses like info@ or support@ that route to group mails rather than individuals. Identifies emails from free providers such as Gmail or Yahoo to separate personal from business accounts. Handles grey listing by spotting temporary server blocks and retrying validation, ensuring valid addresses aren’t marked invalid. Flags disposable or temporary email address to block fake sign ups and maintain list quality. Distinguishes between permanently invalid addresses and temporary issues such as full mailboxes or busy servers.

Analyses multiple validation factors to generate a quality score, helping you predict deliverability.
