Using sccarpebox I am verifying a list of 1.5 millions emails. Scrapebox competition finder will allow me to see if the email in my list can be found in google. If found I will use it as I can say I found the email through google. Using my normal ip I can only check around 5000 email before google puts a block on that email. Using scrapebox harvasted proxies I have lots of problems checking a big list. Halfway the list many proxies seem to fail and I have to restart or do lots of manual work. Therfore I am looking for around 20 fast working proxies. This should allow me to check around 100k mailaddresses per day.
