Here are the 5 most common reasons your email is going to spam.

1. CAN-SPAM compliance

Senders must comply with the Controlling the Assault of Non-Solicited Pornography and Marketing Act of 2003 or CAN-SPAM, which restricts unsolicited emails and sets the standard for sending commercial email. CAN-SPAM is a primary determinant of which emails reach the inbox.

Under CAN-SPAM, senders must comply with numerous rules regarding email content, including:

  1. Don’t use misleading or false information in email headers

  2. Don’t use deceptive language in email subjects

  3. Identify advertising messaging clearly and conspicuously

  4. Inform recipients of your business’ location

  5. Tell recipients how to opt out of future communications

  6. Respect opt-out requests and handle them quickly

  7. Be cognizant of what third parties or others do on your business’ behalf

Complying with the rules is a legal obligation, but compliance is also a best practice for ensuring your emails don’t end up in spam folders.
