Because mail tester is basically a score based system.

And Gmail, Outlook uses machine learning technology to understand every email. These are some rules while sending emails.

1. No TEST or SPAM or Adult Words in the email.
2. No Random words like “uyteiuher” or “8754981250hjb1y98x” something like these formats.
3. Gmail prioritize support, contact, info, updates, join, hire usernames in emails.
4. Email must have a minimum number of words.
5. There should be valid links and unsubscribe button.
6. Email Sending Domain should not be blacklisted in Google Transparency or Norton etc reports.
7. Need some Important x-spam or x-origin these kind of headers ( Optional )

These are some important things, you should follow for better email delivery.
