There is no automatic transfer to a paid package. The trial is completely free of charge and without obligation. After the end of the trial, the domain is automatically removed from our system.
If you are satisfied with the result and you want to switch to a payment plan, it makes sense to upgrade your account before the end of the trial is reached. This allows you to transfer the settings for your domain from the trial phase to the new tariff. The easiest way to perform the upgrade is to click on the button Upgrade to paid plan in the filter administration of your account.
If you no longer wish to use the filter, please note that you must reset the MX settings to the original values before the trial expires. Otherwise, you will no longer be able to receive messages, as EuropeanMX will no longer accept messages once the domain has been removed from our database.
