Extract contacts from emails in mailboxes with LetsExtract

LetsExtract can connect directly to mail servers using POP3 and IMAP protocols. This function can be useful, if you want to extract, for example, addresses of clients with whom there was correspondence from a corporate mail before.

• Both POP and IMAP connection types are supported, including servers which require a secure (SSL) connection.
• For IMAP, you can select a folder from which to extract emails.
• You can easily export the collected contacts to a file, or check emails for validity with LetsExtract Email Verifier, or start sending e-mails with LetsExtract Email Sender.

Update: This feature is best described in the documentation for LetsExtract 7: https://letsextract.com/docs/mailbox_search.htm.
