Number 1 here working HR-agency for IT-specialists in Germany: There is a database of companies (e-mail addresses of the head of the personnel department), thousands of hundred addresses, sorted by industry. A free mailbox on a neutral domain is opened on behalf of the applicant and a database on the chosen industry with an attached resume is bombed on his behalf. The quota of successful employment is gigantic. Sending a resume on their own initiative in Deutschland is not considered spam yet, especially unemployment in the country is considered a problem. I observed the remorse of people with IT-professions who professionally hate spam, who after 20 interviews for 8 days got a job thanks to a cruel spammer.
