The Abstract API Email Reputation API analyzes an email address and provides a reputation score based on various risk factors. It helps identify whether an email is associated with spam, fraud, or poor deliverability, allowing businesses to filter out risky users, improve email engagement, and protect their platforms from abuse.
The Email Reputation API considers multiple factors, including the email’s deliverability status, domain age and history, blacklist records, presence in data breaches, role-based usage (e.g., support@, sales@), and whether it’s linked to disposable or high-risk domains. These insights help determine whether an email is trustworthy or poses a potential risk.
By identifying and filtering out emails with low reputation scores, spam traps, or high bounce risks, the API helps businesses maintain a clean email list. This reduces bounce rates, improves sender reputation, and ensures that messages reach legitimate recipients, leading to higher engagement and better inbox placement.
