Opt-Inbox vs. SaneBox Comparison Chart

We engage with your emails to teach inbox providers not to send your emails to spam. Our clients have seen their open rates more than DOUBLE within 1-2 weeks! Highly engaged recipients not only open emails, but scroll down as they read. So long as the content is longer than the page, this should be done for nearly all opened emails. When a recipient goes out of their way to take an email out of spam, they are telling the inbox provider, hey, you made a mistake. Moving an email from the promotions folder to the primary inbox tells inbox providers that you disagree with their sorting criteria and it and similar emails should go to the primary inbox. Demonstrates that recipient is interested in the content of your email. We have a set of random generic replies we use for this. Marking an email as important can essentially be interpreted by the inbox provider as "This email is extremely valuable, never send it to spam."
