Question 1

Why are my emails going to spam, and how do I check my email DNS?

Accepted Answer

Enter your domain and the tool tests its MX, SPF, DKIM, and DMARC records in one report with a 0–100 health score, showing exactly which records are missing or misconfigured.

Question 2

What does the email DNS health checker test?

Accepted Answer

It runs four checks in one pass: MX records (can the domain receive mail), SPF (are senders authorized), DKIM (is there a valid signing key for common selectors), and DMARC (is there an enforcement policy). Each check gets a pass, warn or fail row with a plain-language explanation.

Question 3

How is the 0-100 score calculated?

Accepted Answer

Each of the four checks is worth 25 points: MX present, a valid SPF record, a DKIM record found for a common selector, and a DMARC policy. A DMARC policy of p=none earns partial credit of 12 points since monitoring is better than nothing but still leaves the domain unprotected.

Question 4

Why is my score low even though email works?

Accepted Answer

Email can function with just MX records, but without SPF, DKIM and DMARC your messages are more likely to land in spam and anyone can spoof your domain. A low score means deliverability and security risk, not that sending is broken right now.

Question 5

Which DKIM selectors does it try?

Accepted Answer

It tries the selectors most providers use: default, google, selector1, selector2 and k1. If your provider uses a custom selector, use the dedicated DKIM Checker tool to test that exact selector.

Question 6

What should I fix first?

Accepted Answer

Fix failures in this order: MX records (nothing works without them), SPF (quick to publish), DKIM (needs your provider key), then DMARC (start at p=none, collect reports, then move to quarantine and reject). Re-run the check after each change to watch the score climb.
