Why My Campaign Got Rejected

At Mailzzy, we take email security and deliverability seriously. Our phishing detection system ensures that harmful emails are blocked while your legitimate marketing messages safely reach inboxes. To help you understand how phishing detection works and avoid potential flags, we’ve outlined the key factors our system evaluates.

Email Content Analysis

Your email may be flagged as phishing if:

• It contains deceptive language designed to trick recipients into taking an action (e.g., sharing sensitive information or clicking a malicious link).

• It uses urgency, fear tactics, or coercion (e.g., Your account will be deleted in 24 hours!).

• It has poor grammar, misspellings, or unusual formatting that suggest fraud.

• It lacks clarity or contains misleading claims.

What’s NOT phishing?

• Emails promoting products, discounts, or services with clear, transparent messaging.

• Marketing emails with legitimate discount codes, product information, or sales offers.

• Campaigns sent via Mailzzy that follow email best practices.

Image-Based Phishing Detection

Mailzzy’s AI scans both text and images in emails. Your email may be flagged if:

• The image contains misleading instructions urging immediate action under false pretenses.

• There are intentional misspellings designed to deceive (e.g., Clikc here instead of Click here).

• It requests sensitive information (e.g., passwords, bank details) under suspicious circumstances.

What’s NOT phishing?

• Promotional images with general marketing content, brand logos, or discount offers.

• Marketing emails with legitimate discount codes, product information, or sales offers.

• Email banners from trusted platforms, such as Sent via Mailzzy or Powered by Mailzzy.

Phishing URL Detection

Mailzzy automatically scans URLs within emails. Your email may be flagged if:

• The link leads to a known malicious or fraudulent website.

• The domain name mimics a trusted brand to deceive recipients (e.g., paypa1.com instead of paypal.com).

How to Ensure Your Emails Are Not Misclassified

To improve your email deliverability and avoid phishing flags:

• Use clear, professional language without misleading statements.

• Avoid excessive urgency tactics unless necessary. Phrases like Claim this offer now! should provide clear context.

• Ensure all links are legitimate and direct to trusted sources.

• Keep image-based text free from misleading offers or deceptive wording.

• Use Mailzzy’s built-in spam detection and deliverability tools to check your emails before sending.

Disclaimer: AI-Based Detection and False Alarms

Mailzzy’s phishing detection system uses AI-powered tools to analyze email content, images, and links. While we strive for accuracy, no detection system is perfect, and legitimate emails may occasionally be flagged.

If you believe your email was incorrectly classified as phishing:

• Review your content using the best practices above.

• Use Mailzzy’s email preview and spam check features to optimize your message.

• Contact Mailzzy’s support team for a manual review and reclassification if needed.

• Keep image-based text free from misleading offers or deceptive wording.

At Mailzzy, we work hard to balance security and deliverability, ensuring your marketing emails reach the right audience safely and effectively.
