About Constant Contact’s spam-detection system

How we keep our deliverability rates high and ensure your communications get to your contacts

What good is your email campaign if it never reaches your contacts? At Constant Contact, we're proud to say our email deliverability rate is best-in-class at 97%!

So how do we do it?

We're able to maintain our high delivery rate with our AI-powered spam-detection system, a sophisticated algorithm developed by Constant Contact to help protect against spam and malicious content in emails.

It uses the latest machine-learning techniques to scan every email that passes through the system, analyzing each message for suspicious behavior and content, such as phishing attempts, malware, or other types of malicious software that may harm the recipient's and sender's reputations.

We scan billions of emails each month, and the system is highly accurate, meaning that legitimate emails are not typically flagged as spam or malicious. We continually monitor and improve the system to ensure that our customers' emails are safe, secure, and effective.
