Hi @YahoM
These are great questions! When it comes to your contacts, there is no limit to how many email addresses can be added in your account. Although there is no limit, it's always important to keep in mind we do charge based on the amount of active contacts in your account. So as your contact levels increase, so will your monthly charge. On the other hand, there is an existing limit of how many contact lists you can have. You are correct, this limit is 1,000 lists. Why you would want to have more lists? (E.g., very large list customer, very old list with years of data, needs to have historical record of lists and contacts.) Also, how do you typically use/manage their lists? Having these details is helpful feedback as having more than 1,000 lists is a feature request I can submit in your account.
