hello @gapeyrot, thank you for your request!
Yes, the video is a good source to learn from!
The most important is “status”, and the other columns could elaborate more details.
status - status of an email: RECEIVING - email is valid, INVALID - email is invalid, BLACKLISTED - email was found in a blacklist, UNKNOWN - the service cannot determine if the email is valid or not. valid_format - specifies if the general format of an email is correct. in_blacklist - specifies if an email was found on a blacklist (complainers, email traps). valid_dns - specifies if the DNS records of the email domain are valid. valid_smtp - specifies if an email accepts emails via SMTP.
