Professional Email Replies. Private by Design.
SwiftSend AI writes replies in your voice and saves you hours each week. But behind every reply is a deeply considered security model built to protect your inbox at every step. Here's exactly how it works.
How SwiftSend AI Understands Your Emails
SwiftSend AI isn't just prompt-based. When you forward a thread, it reads the entire conversation history. This allows it to see the full context, who said what, what was promised, what tone the other party is using, and what stage the conversation is in. This thread-awareness gives the tool its edge in professionalism and relevance.
To ensure it sounds like you, SwiftSend AI uses adaptive prompt engineering that mirrors your previous inputs and preferences. Whether you speak with warmth, precision, brevity, or authority, SwiftSend AI adjusts to fit. You can also give high-level cues like “be more casual” which it interprets in the tone of your usual communication style.
Most importantly, SwiftSend AI never connects to your inbox. You control what it sees by forwarding emails manually. No plug‐ins, no integrations, and no background access.
Security and Privacy
We know that forwarding sensitive emails requires real trust. SwiftSend AI was built from the ground up with privacy and security in mind. Here is a full breakdown of our protocol.
Encrypted in Transit
The moment your email leaves your outbox and travels to our secure inbox, it is encrypted using TLS (Transport Layer Security). This protects your message from interception or tampering as it moves across the internet.
Encrypted at Rest (AES-256)
As soon as your email reaches the SwiftSend AI system, it is immediately encrypted using AES-256, an industry-trusted encryption method recognized for protecting sensitive data.
Auto Deletion After 8 Hours
Messages are retained only as long as necessary. After 8 hours, they are automatically and permanently deleted from our system. No long-term storage. No training. No backups.
Rotating SMTP Credentials
To secure the inbox that receives your forwarded messages, the SMTP password is rotated every 4 days. This limits the window of opportunity for credential-based access and matches enterprise-grade practices.
Built for Professionals Who Value Trust
Your inbox holds sensitive conversations, high-stakes negotiations, and important follow-ups. SwiftSend AI treats that responsibility seriously. With encrypted handling, short-term retention, and your full oversight at every step, SwiftSend AI gives you the power of automation without sacrificing control.
