WHAT WILL SEARCHBUG CHECK and ADD TO MY FILE?

    • We will check to ensure the email address will be accepted by the receiving email server for delivery. Safe to email. The bounce rate is under 2%.
      The results will be returned in a CSV (comma-separated values) text file. You can open CSV files with Excel. The file will contain all your original data with New columns added at the end.

    • STATUS. Using Real-time verification in carrier billing systems And other advanced proprietory methods the following statuses are reported
      • VALID - Email Address will be accepted by the receiving mail server for delivery. Safe to email. Bounce rate is under 2%. Not a CATCH-ALL email (see below).
      • INVALID - Mail Server will reject email or Email account does not exist or No mail server for the domain or Domain is not valid or Email format is incorrect. The results almost 100% accurate. See SUB-STATUS column for details.
      • CATCH-ALL - Some corporate email servers, will always return a VALID response, whether the email address is actually valid or invalid. They do this to prevent people from harvesting real email addresses from their mail server. In other cases, mail operators collect all emails sent in valid invalid accounts (e.g., misspelledname@domain.com) to the mail administrator will forward that email to a "catch-all" address, like review@domain.com to review at all the emails sent to their mail server to see if anything important was sent to an invalid recipient.
      • SPAMTRAP - An email address not used by a person, but actively monitored. If a spam trap receives an email, it will consider it as spam because that email address never opted in to receive emails.
      • ABUSE - high risk emails, where recipient clicks the "Spam" link often.
      • DONOTMAIL - either a group email (SUB-STATUS = role_based) or a possible trap. Do not use.
      • UNKNOWN - Status cannot determined. Domain is valid, receicing mail server exists, but we did not get the reponse in time. An anti-spam system might be blocking the access. You are not charged for UNKNOWNs.

    • SUB-STATUS. Additional information, if available
      • alias_address - forwards to a valid real address (e.g. webmaster@mysite.com to joe@mysite.com)

      • does_not_accept_mail - domain can send, but not receive email
      • exception_occurred - mail server error
      • failed_smtp_connection - connection to mail server failed (likely invalid)
      • failed_syntax_check - email format is invalid (e.g. name$mysite.com)
      • forcible_disconnect - connection to mail server dropped (likely invalid)
      • global_suppression - email is found in a global suppression list (GSL). Do not email.
      • greylisted - temporarily unable to validate. You can try again later.
      • leading_period_removed - valid gmail.com email address can start with a period '.' We will remove it, to make it compatible with all mailing systems
      • mail_server_did_not_respond - server not responding to mail requests (likely invalid)
      • mail_server_temporary_error - mail server reports a temporary error (likely invalid)

      • timeout_exceeded - no response from the server in 60 seconds. You can try again.
      • unroutable_ip_address - emails domains point to an un-routable IP address

    • DISPOSABLE. True (Yes) or False (No). Temporary email address created for the sole purpose to register without giving the real email address. Disposable emails may only last from a few minutes to a few months.
    • TOXIC. True (Yes) or False (No). Domains are known for spam or abuse, and bot created email addresses.

    • Some corporate email servers will always return a Valid response regardless if the email address is actually valid or invalid. They do this to prevent people from harvesting real email addresses from their email server.
    • In other cases, email operators collect all emails sent as valid. Then valid accounts like misspelledname@domain.com are sent to the email administrator which forwards that email to a "catch-all" address, like review@domain.com to review all the emails sent to their email server to see if anything important was sent to an invalid recipient.

    • We will tell you if the email address in your file has a does_not_accept_mail server meaning the domain can send, but not receive email
    • We will tell you if an exception_occurred meaning the email server has an error receiving email for that address.
    • We will tell you if we receive a failed_smtp_connection error meaning the connection to email server failed which makes the email address likely invalid but we didn’t receive a definitive email invalid response.

    • We will tell you if the email server is not responding to mail requests which also make the email address likely invalid and we suggest removing these as well. These email addresses will have mail_server_did_not_respond designated in our returned file to you.
    • We will tell you if the mail server reports a temporary error which also makes the email address likely invalid and we suggest removing these as well. These email addresses will have mail_server_temporary_error designated in our returned file to you.
    • We will tell you if the email account does not exist on the mail server and designate those with a mailbox_not_found so you can purge these from your list and save the hassle of cleaning bounced emails afterward, also saving your email reputation.
    • We will tell you if the account exceeded their space quota and are not accepting emails and designate those addresses with a mailbox_quota_exceeded so you can purge these from your list as well. Remember that bounced emails are harmful so you want to avoid sending any email that can potentially bounce. When users exceed quotas it typically indicates an email account they don’t use often or use for opt-ins knowing they rarely if ever check them. Don’t waste time sending emails to them.
