I have 400 email accounts (Gmail, Yahoo, AOL) that I'm using as "seeds" to manipulate the feedback sent back to my private server. I have been sending messages from the SMTP server to these accounts every hour for the past 10 days and manually opening/clicking/replying and moving from spam to inbox. Is there any way to automate this? If it can't be automated (I.E. ZennoPoster), does anyone know of a Windows 10 mail client that can hold unlimited email addresses and make it easier for me to toggle between accounts? So far Thunderbird seems like my best option. Gmail iOS app and Yahoo Mail app both suck. Do you know any creative tricks to boost reputation? I'm already using the Craigslist trick and 1 other one... but I need more opens/clicks/replies. Google Postmaster Tools are showing High IP & Domain Reputation and MailTester gives me 10/10 score, but i'm still getting stuck in Yahoo/Gmail spam box A LOT. Any tricks to overcoming this?
