What Is IP Address Reputation?
IP reputation measures the behavioural quality and trustworthiness of an IP address.
For instance, an IP address consistently sending spam-free emails will receive a “good” reputation score. In contrast, IP addresses involved in sending bulk spam or associated with malware and harmful domains will have a poor IP reputation. Also see anonymous proxy database IP blacklist
How does IP reputation play a crucial role?
IP reputation is highly significant because it plays a crucial role in email deliverability. A positive IP reputation enhances the likelihood of your email campaigns reaching your subscribers’ inboxes, whereas a poor reputation may result in emails being diverted to spam folders or not being delivered at all.
To elaborate further, Each device connected to the internet possesses an IP address, regardless of whether it’s a personal computer or a server designated for sending emails. When employing an email marketing service to dispatch your email campaigns, the email service providers (ESPs) utilize servers for this purpose, and these servers are assigned their own unique IP addresses.
