Spam tests typically evaluate several key elements of your email:
Subject Lines: Certain words and phrases can trigger spam filters. It's essential to avoid using terms like "Free," "Buy Now," and "Click Here." Content: The body of the email is scrutinized for spammy language, excessive use of capital letters, and suspicious links. Formatting: Poorly formatted emails with too many images or HTML errors can be flagged as spam. Sender Reputation: The reputation of the sender's domain and IP address plays a significant role in spam filtering. Email Authentication: Ensuring that your emails are authenticated using SPF, DKIM, and DMARC can improve deliverability.
