About IP Reputation

This tool analyzes your IP address reputation by checking reverse DNS configuration, blacklist status, and IP characteristics that affect email deliverability and sending reputation.

Why check IP reputation?

IP reputation directly impacts whether your emails reach the inbox or get blocked. Mailbox providers use IP reputation as a key signal to filter spam and protect their users.

Understanding IP Reputation Factors

IP reputation is determined by multiple factors that signal trustworthiness to email providers and security services.

block Blacklist Status: Being listed on IP blacklists is the most damaging factor for email deliverability. Blacklists are used by mailbox providers to filter spam at the network level.
dns Reverse DNS (PTR Records): PTR records map an IP address back to a hostname. Most email servers require valid reverse DNS before accepting mail from an IP address.
public IP Type and Range: Whether an IP is public or private, IPv4 or IPv6, and the reputation of the surrounding IP range all influence how email from that IP is treated.
history Sending History: The volume and pattern of email sent from an IP over time builds its reputation. Sudden spikes in volume or high bounce rates damage reputation quickly.

Maintaining Good IP Reputation

Follow these best practices to build and maintain a strong IP reputation for reliable email delivery.

check Configure Reverse DNS: Set up PTR records that resolve to a meaningful hostname matching your sending domain. This is a baseline requirement for most email servers to accept your mail.
check Warm Up New IPs: Gradually increase sending volume on new IP addresses. Start with your most engaged recipients and slowly ramp up to build a positive sending history.
check Monitor and Respond: Regularly check your IP against blacklists and monitor bounce rates. Address issues immediately to prevent long-term reputation damage.
