One inbox for every address you own
Your member mailbox @B31.Si, VIP aliases, your business domain and your existing Gmail, QQ or 163 accounts — all in one inbox. Every message shows which address it was sent to, and your reply goes out from that same address automatically. 龍華樹 ASI drafts replies, summarizes long emails and flags what matters today.
Built for people who live in their inbox
Amail is the mailbox service of the Zhenbai (紫微星会) membership community. It is for person-to-person email: your own correspondence, replies and new messages to your contacts.
Unified inbox
B31.Si mailbox, VIP aliases, business domains and linked Gmail / QQ / 163 accounts arrive in one place, each tagged with the address it was delivered to.
Reply from the right address
Mail sent to sales@ is answered as sales@; mail from your linked Gmail is answered through Gmail. No more replying from the wrong identity.
AI that does the busywork
One-line intent to a full draft reply, three-line summaries, polishing, and an inbox triage into today / this week / ignore.
Butler & daily digest
Urgent and important mail is flagged automatically, verification codes are one tap to copy, and a morning digest lists what needs you.
Your business domain
Bind your own company domain (SVIP): any prefix is received into the same inbox, with DKIM, SPF and DMARC set up for you.
AI agents welcome
Let Claude, ChatGPT, Gemini or your own agent read, sort and draft mail through MCP or OpenAPI with a revocable key that can never delete mail.
Private by default
Remote images are blocked to stop read-tracking, sender authentication is shown on every message, and we never use your mail for ads.
Phone & desktop
Android app with new-mail notifications; on iPhone add mail.b31.si to your Home Screen. Works great inside WeChat and on slow networks.
Simple pricing
Plans are paid in 紫微星币 (✦), where ✦1 = US$1. Top up with card, PayPal, USDT, WeChat Pay or Alipay.
