We collaborate closely with you to ensure that your email providers refrain from delivering spam to your inbox. Within just a few weeks, our clients have reported their open rates skyrocketing to more than double! Recipients who are highly engaged tend to open emails and actively scroll through the content as they read. This engagement should occur for nearly all opened emails, provided that the information is concise enough to fit within a single page. When a recipient retrieves an email from the spam folder, it indicates to the inbox provider that they believe an error has occurred. Furthermore, if someone shifts an email from the promotions tab to the primary inbox, it signals to the provider that their sorting method may not align with user preferences. Such actions suggest that those emails, along with others like them, should be directed straight to the main inbox. This behavior demonstrates genuine interest in the content of the email, leading inbox providers to interpret it as "This message is of utmost importance; please ensure it is not categorized as spam." As a result, building a positive relationship with your email recipients can significantly enhance your overall engagement rates.
