# Allowlisting Prventi email servers

To ensure that Prventi's phishing simulation emails reach their intended recipients without being blocked by spam and phishing filters, it is essential for receiving email servers to allowlist Prventi's mail servers. Allowlisting helps establish a trusted connection between the sender and recipient, allowing our simulated phishing emails to bypass filtering mechanisms and provide an effective training experience for your team. By following the allowlisting instructions provided in our help documentation, you can ensure a seamless and reliable delivery of Prventi's phishing simulations, helping your organization improve its overall security awareness.
