Test the Spammyness of your Emails

What is an Email Spam Tester?

An Email Spam Tester is a diagnostic tool that simulates a real email receiving environment. It analyzes the technical setup of your email server (DNS records, IP reputation) and the content of your message to calculate a "Spam Score." This score predicts the likelihood of your email reaching the recipient's Inbox versus getting filtered into the Spam/Junk folder.

Major email providers like Gmail, Outlook, and Yahoo use sophisticated algorithms to filter incoming mail. If your email lacks proper authentication or contains suspicious content, it will be blocked. Our tool helps you identify these issues before you send your campaign.

Why Email Deliverability Matters

• Marketing ROI: If your newsletters land in spam, your open rates drop to zero, wasting your marketing budget.
• Transactional Reliability: You need to ensure password resets and order confirmations reach your customers instantly.
• Domain Reputation: Sending spammy emails can damage your domain's reputation permanently, making it hard to ever reach the inbox again.

Key Factors We Analyze

1. SPF (Sender Policy Framework)

SPF is a DNS record that lists which IP addresses are allowed to send email for your domain. It prevents spammers from spoofing your address.
Common Error: "Softfail" - This means your email was sent from an IP not listed in your SPF record.

2. DKIM (DomainKeys Identified Mail)

DKIM adds a digital signature to your emails, verifying that the message hasn't been tampered with during transit.
Common Error: "Signature Invalid" - Often caused by email forwarding or incorrect DNS keys.

3. DMARC (Domain-based Message Authentication)

DMARC is the policy that tells receiving servers what to do if SPF or DKIM fails (e.g., "Reject" the email). Google and Yahoo now require DMARC for bulk senders.

4. IP Blacklists (RBLs)

We check your sending IP against major blacklists like Spamhaus and SpamCop. If your IP is listed, your emails will be blocked globally.

5. SpamAssassin Score

SpamAssassin is an open-source filter used by thousands of servers. It checks for "spammy" traits like:
- SHOUTING IN CAPS
- Excessive use of "Free", "Money", "Click Here"
- Low text-to-image ratio (sending images without text)

How to Improve Your Score

1. Authenticate Your Domain: Ensure you have valid SPF, DKIM, and DMARC records in your DNS.
2. Warm Up Your IP: If you have a new IP address, send small volumes of email initially and gradually increase over time.
3. Clean Your List: Remove inactive subscribers. High bounce rates damage your reputation.
4. Check Content: Avoid spam trigger words and ensure your HTML code is clean.

Use this tool regularly to monitor your email health and ensure your messages always land where they belong: in the inbox.
