Abstract
Methods, systems, and computer programs are presented for validating if an email address is a valid email address. The validation includes a combination of rules-based heuristics (e.g., non-existing domain name) and a validity score calculated by a machine-learning model. The machine-learning model makes predictions based on the training data set that includes historical information about email addresses. The information obtained from the rules and the validity score is combined to determine the probability that the email address is a valid email address.
