So I've tested out the tool a couple times and realized that it doesn't just send out emails in bundles, it sends them all at once. Which then puts a ban on the email because it tries to send more than the maximum amount at a period of time. I think it was like 500 in so many hours. How can I send out batches of emails in a newsletter with the email to users tool without getting my email banned like that? Is there a setting somewhere that I'm not seeing?
