When you add new contacts to your Mailercloud account, the platform utilizes advanced algorithms to analyze the data and determine the nature of each contact, whether it's valid, spam, bounced, or unknown.
This analysis is conducted based on Mailercloud's extensive deliverability history, which allows for the identification of patterns and trends in email campaigns. If a contact's data matches a pattern associated with a valid email address, Mailercloud will classify it as valid. Similarly, if the data matches a pattern associated with a known spam email address, Mailercloud will classify it as spam.
However, in cases where the algorithm cannot definitively determine the contact's status as valid or spam, it will be categorized as unknown. This means that you can only ascertain the contact's status, whether it's valid, spam, or bounced, after the campaign has been executed.
To optimize your email deliverability and ensure that your messages reach your intended audience, it is crucial to regularly monitor your email campaigns and make adjustments to your email list based on the feedback you receive from Mailercloud. By doing so, you can improve the effectiveness of your email marketing efforts.
