Question 1

What does the Personalization Checker tool check?

Accepted Answer

The Personalization Checker tool analyzes your email content, domain configuration, and sending infrastructure for factors that affect whether emails reach the inbox or land in spam. It checks against rules used by major spam filters and email providers including Gmail, Outlook, and Yahoo. The tool identifies specific issues — such as missing authentication, spam trigger words, poor text-to-image ratio, or missing unsubscribe links — and explains how to fix them.

Question 2

What are the most common causes of emails going to spam?

Accepted Answer

The most common causes of emails landing in spam are: (1) Missing or failing SPF, DKIM, or DMARC authentication. (2) Sending from a new IP or domain without a warm-up period. (3) High bounce rates or spam complaint rates (above 0.1% triggers filters). (4) Spam trigger words in subject lines or body. (5) No unsubscribe link in bulk email. (6) Poor text-to-image ratio (image-heavy emails are suspect). (7) Domain or IP on blacklists. Fix these issues systematically using our free deliverability tools.

Question 3

What is a good email spam score?

Accepted Answer

Most spam filter scoring systems (including SpamAssassin, which our Spam Score Checker is based on) consider a score below 2.0 to be acceptable. Scores between 2.0 and 5.0 indicate potential issues that should be investigated. Scores above 5.0 significantly increase the likelihood of spam classification. Common score contributors include missing authentication records, spam trigger words, all-image emails, shortened URLs, and excessive punctuation in subject lines.

Question 4

How do I improve my email inbox placement rate?

Accepted Answer

To improve inbox placement: (1) Set up SPF, DKIM, and DMARC correctly. (2) Warm up new IPs gradually — start with small volumes and increase over weeks. (3) Keep bounce rates below 2% and spam complaint rates below 0.1%. (4) Send only to engaged subscribers — segment and suppress inactive users. (5) Use double opt-in to ensure valid, consenting recipients. (6) Include a working unsubscribe link. (7) Monitor your sender reputation and blacklist status regularly.
