Email Spam Rating Checker

See how likely your email is to be marked as spam — and why.

See all checkers

You can write the perfect email and still never reach the inbox. Mailbox providers like Gmail and Outlook score every message against the same handful of signals — is the sender authenticated with SPF, DKIM and DMARC, does the domain accept mail, and is it on any blacklists? Miss those and your mail quietly lands in spam, or bounces. A spam rating checker grades your domain against exactly those signals so you can see what is holding your deliverability back.

What it checks

SPF — is a sender policy published, and is it strict (-all)?
DKIM — is your mail cryptographically signed?
DMARC — is there an enforced policy (quarantine/reject), not just monitoring?
MX — does the domain accept mail at all?
Blacklists — is the domain or its mail IPs listed anywhere?

Why it matters

Authentication is no longer optional — Gmail and Yahoo now require SPF, DKIM and DMARC for bulk senders, and treat unauthenticated mail with suspicion. Each missing piece nudges more of your email toward the spam folder, and the failure is silent: you only notice when replies stop arriving. A single score that rolls up every signal turns a vague "our emails go to spam" into a specific, fixable checklist.

How BrandSentryPro does it

Add your domain and BrandSentryPro checks your SPF, DKIM and DMARC records, your MX setup and your blacklist status, then rolls them into a spam-rating grade from A+ to F with a fix for every gap. It re-checks on a schedule and alerts you if a new problem appears — for example a DNS change that breaks SPF — so your deliverability never quietly degrades.

Frequently asked questions

What is an email spam rating?

It is a single score that estimates how likely your email is to be marked as spam, based on the authentication and reputation signals mailbox providers use — SPF, DKIM, DMARC, your MX configuration and whether you are blacklisted. A higher score means a better chance of landing in the inbox.

Why does my email go to spam?

The most common causes are missing or weak authentication (no SPF, DKIM or DMARC, or a permissive policy), being on a blacklist, or a poor sending reputation. A spam rating checker pinpoints which of these apply to your domain so you can fix the right one.

Do I really need SPF, DKIM and DMARC?

Yes. Major providers including Gmail and Yahoo now require all three for bulk senders and increasingly distrust mail without them. Setting them up is the single biggest thing most senders can do to improve deliverability.
