Link building throttle on full speed - I just bought these tools: Scrapebox to scrape for URLs and filter them with kws: guest post, write for us etc. - > hunter.io to find emails, but should I just drop hunter.io and use scrapebox email finder instead? -> ?? Then what software to use to send the emails? Mailshake vs gmass? I need several different gmail accounts on one user if possible because I will be doing guest post for different blogs. Any suggestion my good bhw members?
