Domain & DNS Check: A domain and DNS check can reveal issues such as incorrect or outdated DNS records, DNS propagation delays, domain name hijacking, and DNS cache poisoning. These issues can affect email delivery, and online security. By performing domain and DNS checks, we ensure that the domains and DNS records are properly configured and functioning as intended for the purposes of receiving an email.

Smart Duplicates Removal: Smart duplicates removal is a process that identifies duplicate email addresses, allowing email senders to avoid paying twice to validate the same address. This is especially important when dealing with large databases or exported lists, which can contain the same email address more than once. By identifying these duplicates, email senders can save costs and avoid mailing the same contact multiple times, which can lead to a negative user experience and harm the sender’s reputation.

Mail Exchanger Test(MX): A Mail Exchanger (MX) test is a diagnostic used to check the configuration of a domain’s DNS (Domain Name System) records responsible for email delivery. This test verifies the validity and accuracy of MX records, including the priority assigned to each mail server. Properly configured MX records ensure that email messages reach their intended recipients, whereas misconfigured or invalid MX records can result in email delivery issues. MX tests are particularly useful for troubleshooting email delivery problems and identifying and correcting issues with the MX records, helping to prevent email delivery problems and ensure that important messages are received by their intended recipients.

Syntax Verification: Syntax verification in emails refers to the process of checking whether an email address is properly formatted according to established rules and standards. This process involves examining the email address to ensure that it includes a valid username, followed by the “@” symbol, and then a valid domain name. Syntax verification also checks for the correct use of special characters, such as periods, hyphens, and underscores, in the username and domain name. If an email address fails syntax verification, it is considered invalid and may not be deliverable. This process helps to prevent typos and errors in email addresses, reducing the likelihood of undeliverable messages and email scams.The syntax engine used here follows all the IETF standards that are relevant, which include: RFC 1123, RFC 2821, RFC 2822, RFC 3490, RFC 3696, RFC 4291, RFC 5321, RFC 5322 and RFC 5336. It also has complete support for quoted strings and quoted pairs, along with comments and domain literals.

Mailbox Confirmation: This process confirms the presence of a particular mailbox without alerting the intended recipient or sending any emails. It typically involves connecting to the mail server associated with the email address and querying it to determine whether the mailbox exists. This can be done through a variety of methods, such as through an SMTP (Simple Mail Transfer Protocol) connection or by using specialized mailbox confirmation tools.

International Verification: International verification is the process of verifying all contacts, including those who use non-Latin alphabets like Chinese, Arabic, or Cyrillic. This verification process supports both internationalized domains and mailboxes and utilizes Unicode (Punycode and UTF-8) to ensure accurate verification of all contacts, regardless of their location or alphabet. By implementing international verification, businesses and organizations can ensure that they are effectively communicating with all their contacts, regardless of the language or alphabet used.

Catch All Detection: Catch-all detection is a process that identifies mail servers that accept all emails to their domain, including those that are fake, false, or non-existing. This type of server configuration can cause issues with certain Email Service Providers (ESP) and may reduce the open rate of emails. By detecting catch-all servers, email senders can improve their email deliverability and ensure that their messages reach their intended recipients.

Temporary Unavailability: Temporary unavailability detection is a process that identifies mailboxes that are temporarily unavailable. When such mailboxes are detected, our premium level services automatically retry sending emails to these addresses at specific intervals. This helps to avoid graylisting and ensures that a definitive result is returned. By using this service, email senders can improve their email deliverability and ensure that their messages reach their intended recipients, even if the recipient’s mailbox is temporarily unavailable.

Role Account Detection: Role account detection is a process that identifies common role accounts, which are generic email addresses that are not typically associated with a specific individual. Examples of role accounts include sales@verifyemailnow.com or info@verifyemailnow.com, and others. Sending emails to these types of addresses can negatively impact email deliverability and even result in blacklisting by certain Internet Service Providers (ISPs). By detecting and avoiding the use of role accounts, email senders can improve their deliverability and ensure that their messages are received by the intended recipients.

Disposable Email Check: Disposable email check is a process that identifies temporary email addresses created by known disposable email providers such as Mailinator, YOPmail, and others. This check is performed against an extensive list of known disposable email domains to keep the bounce rate low. Our exclusive neural network is even capable of detecting the most impregnable providers, such as EmailOnDeck. By performing this check, email senders can improve their email deliverability and avoid sending messages to temporary or fake email addresses.

Spam Traps Detection: Spam traps removal is a process of identifying and eliminating spam traps and other honeypots. This is achieved by using our exclusive Artificial Intelligence neural network to detect spam traps, honeypots, and spam complainers. By removing these harmful elements from email lists, email senders can improve their email deliverability and reduce the likelihood of their messages being flagged as spam or blocked by ISPs.

Free Email Detection: Free email detection is a process of identifying email addresses hosted by known free email providers such as Gmail, Yahoo, Hotmail, Outlook, and others. This process automatically flags these email addresses, allowing email senders to easily filter them out from their mailings. By avoiding free email providers, email senders can improve their email deliverability and ensure that their messages reach their intended recipients.
