Make a text file with all your emails (1 per line), then create a Multi Run Job and load that file as a wordlist, use the type Emails when loading it. Then inside your config you can use the variable input.EMAIL which is already created and filled for you. Each time a bot runs, it will get a new email from the wordlist and your config will use that one. Remember to not set too many bots when using puppeteer because it takes a lot of RAM.
