What are security limits used for in account engagement?

Security limits are mechanisms in account engagement used specifically to set maximum thresholds for actions performed within the platform, such as the number of emails sent. This feature is crucial for maintaining compliance with best practices in email marketing, preventing spam, and ensuring that the account does not exceed limits that may lead to penalties or reduced deliverability. By using these limits, organizations can protect their sender reputation, manage resources effectively, and tailor their marketing strategies in alignment with their outreach goals.

The other options listed do relate to aspects of account engagement but do not accurately describe the specific role security limits play. User permissions for folders pertain more to access control rather than send limits, while tracking website visitor data and optimizing performance are functionalities that deal with metrics and site efficiency rather than security parameters.
