HELO Description
HELO is a desktop application that streamlines the email testing and debugging process for web developers by capturing and analyzing outgoing emails produced by applications in the development phase. Rather than dispatching emails to actual recipients, HELO offers a local SMTP server that intercepts these messages and presents them within the application, enabling developers to review and validate them prior to launching. This method is instrumental in avoiding frequent issues such as broken links, missing images, formatting mistakes, and other errors that can surface in live emails. It delivers comprehensive debug views that showcase the email in various formats, including HTML rendering, plain text, raw source code, and complete message headers, thus providing developers with an in-depth understanding of the email's structure. Additionally, automated validation tools are employed to check links within the email, ensuring they yield valid HTTP responses, which significantly mitigates the chances of sending emails that contain invalid or broken URLs. By integrating these features, HELO not only enhances the development workflow but also promotes confidence in the quality of email communications before they reach end users.

InboxAlly
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."
