Pre-validating an email recipient and domain

An email coordinator comprising:

• a processing device, and
• a memory device configured to store a computer program having instructions that, when executed, enable the processing device to
• obtain a recipient email address entered in an address field of an email message that is being composed by a sender, and
• check validity of the recipient email address, by communicating with a certificate authority (CA)-based email coordinator that maintains a directory of validated domains and validated users, to identify one or more possible issues in the recipient email address before the email message is permitted to leave a sender's device, wherein the checking further comprises applying machine learning models to analyze both the recipient address and contextual content of the email body to determine consistency between the recipient domain and the content,
• wherein determining consistency comprises:
• (i) scanning the email body to identify one or more words or phrases indicative of a message context, (ii) determining, based at least in part on the directory of validated domains and validated users, whether the identified message context correlates with the recipient domain or a recipient identity associated v with the recipient email address, and (iii) when the correlation fails a threshold, genera an alert that requests confirmation that the sender intends to send the email message to the recipient email address.

A method comprising steps of:

• and
• checking validity of the recipient email address, by communicating with a certificate authority (CA)-based email coordinator that maintains a directory of validated domains and validated users, to identify one or more possible issues in the recipient email address before the email message is permitted to leave a sender's device, wherein the checking further comprises applying machine learning models to analyze both the recipient address and contextual content of the email body to determine consistency between the recipient domain and the content,
