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."

Description

In our quest for a cost-effective, straightforward, and efficient method to assess the quality of our newsletters, we developed our very own testing tool. We're excited to offer it for free through our web interface, allowing you to integrate our tests into your applications and whitelist our service by creating an account. As enthusiastic email software engineers, we generate a unique email address each time you visit our portal. To utilize our service, simply send a message from your preferred newsletter or email software to this newly generated address. After sending, click on the "check your score" button, and once we receive your message, our system will provide your spam score. Mail-tester will thoroughly examine your email, mail server, and sending IP, delivering a comprehensive report that outlines what is configured correctly and what requires attention. It's important to note that spam filters vary widely, meaning that while your email may pass through mail-tester, it might still be flagged in your personal office inbox due to different filtering criteria. Additionally, the final outcome can also be influenced by individual user preferences and settings. Therefore, it's advisable to conduct multiple tests to ensure deliverability across various platforms.
