The eFile website sends out thousands of automated emails and at times can be flagged down as a spam email by the receiving email server (your email service). If a receiving server (your email service) continually rejects the automated emails from the eFile website, the outgoing eFile email service will blacklist the receiving email (your email). The blacklist is designed to protect those email servers that identify the outgoing eFile email as spam. Basically the eFile email service wants to avoid spamming any users due to all the rejected attempts.
If you believe your email has been blacklisted, please contact our technical support team by clicking here. Please include the email that is believed to have been blacklisted. Please also follow the whitelisting instructions in the link below. A failure to whitelist can have your email back on the blacklist.
