Non-repudiable Audit Trail
Built for security drills and core business. MTA delivery records combined with email content hash retention provide non-repudiation similar to a blockchain ledger.

AI-Driven SMTP Semantic Debugging
Translating obscure underlying response codes into intuitive logistics-style tracking recommendations
Edge AI Semantic Analysis
Leverages locally deployed 7B micro language models to accurately interpret non-standard SMTP responses without public cloud privacy risks.
15-Stage Process Awareness Tracking
Combined with MTA connection stages (Stage Awareness), precisely locates fault nodes: sender end, network layer, or recipient security block?
Smart Retry Decisions
AI automatically identifies fake 5xx temporary blocks, preventing invalid bounces and triggering smart retries to maximize delivery rates.
API Log Visualization Embed
Provides structured JSON and CSS templates. Developers can directly embed delivery progress charts into products, reducing support tickets by 30%.
AI Conclusion: Firewall Rejection
Reason: Sender IP listed in international blacklists.
Suggestion: Suspend sending to this domain, check IP reputation and DMARC settings.
Email Tracking: As Simple as Logistics
No more parsing logs! Intuitive "Node-based Progress Bar" and clear indicators help pinpoint issues instantly. Perfectly solves the corporate pain point of "I sent it!" vs "I didn't receive it!".

Recipient Server Rejected (550 Policy Rejection)
The email successfully reached the recipient's gate but was blocked by their firewall (not a system delivery failure). Successfully shifts the blame and frees up your IT department.
"It looks like the recipient's corporate firewall blocked this email. This is usually due to sensitive words or characteristics. Suggestion: remove the executable file from attachments, or ask them to whitelist our IP."
AI Email Server Diagnostics Center
Worried your email templates might trigger spam filters? We provide a dedicated AI Template Health Check tool! Deeply scan your HTML structure and semantics during the template creation phase to eliminate potential spam triggers and ensure high deliverability from the source.
A. Content & Semantic Analysis
- Spam Keyword Detection: Checks for trigger words like "Free", "Act Now". Understands context.
- Phishing Intent: Compares display text with link domains to prevent potential phishing flags.
- Urgency Analysis: Bank notices shouldn't have promotional tones; AI suggests corrections.
B. Structure & Code Review
- Structural Integrity: Scans HTML to prevent unclosed tags that break layouts.
- Text-to-Image Ratio: Calculates ratio. Warns if text is too sparse leading to spam flags.
- RWD Compatibility: Warns about mobile-incompatible syntax (e.g. position: fixed).
C. Variable Logic & Layout Shift
Analyzes overall structural stability and IP reputation to optimize your sending strategy.
AI Semantic Traffic Control
Breaks out of traditional SMTP limits that rely solely on 4xx/5xx error codes. When the SMTP Delivery Server transmits emails, our system analyzes the natural language meaning of the recipient server's response. By understanding the real reason for temporary rejections (e.g., mailbox full, suspected spam), it automatically adjusts retry strategies to prevent blind retries from getting your IP blocked.
Precise control over email success rate and arrival time
AI deeply understands returned strings to grasp the true cause of bounces.
Automatic retry strategies and congestion mitigation
Precisely identifies over quota states to pause retries and protect IP reputation.
Break Through Traditional Error Code Blind Spots
Should 550 or 502 trigger a retry? Traditional servers misjudge based on rigid error codes. We use semantic analysis to perfectly distinguish between temporary blocks and invalid accounts avoiding blind retries.
Traditional Mail Server
Relies only on codes (e.g., 452), missing the context.
➜ Blindly queues for retry, wasting resources and risking IP bans.
DijiMai Semantic Flow
AI parses the response text directly.
➜ Identifies 'over quota', pauses retries for this user, entirely protecting IP reputation.
