Compare CleanTalk vs. Proxmox Mail Gateway

We work with you to make sure your inbox providers don't send spam emails to your email. In just a matter of weeks, our clients have seen their open rates increase by more than DOUBLE! High-engagement recipients open emails and scroll down as they read. This should be done for almost all emails that are opened, as long as the content is not longer than the page. If a recipient takes an email from spam and goes out of their way, it is telling the inbox provider that they made a mistake. Inbox providers will be able to tell if you move an email from the promotions folder into the primary inbox that you don't agree with their sorting criteria. It and other similar emails should go directly to the primary mailbox. It shows that the recipient is interested in your email content. The inbox provider can interpret this as "This email is extremely important, please do not send it to spam."
