FAQ
Four common pre-signing questions
01
Will any current mail be lost in migration?
No. IMAP full-sync + verification, labels / folder structure preserved, diff-check after migration before switchover.
02
Will employees need a new mobile app?
No. Gmail app / iOS Mail / Outlook all accept enterprise mail. We provide config docs.
03
Can we keep our old mailbox addresses?
Yes. Aliases + forwarding rules — old addresses' mail flows into new mailbox. Common setup.
04
Where's data stored? Can anyone see it?
Aliyun east China nodes, your data. Our ops only have incident-response access (audited). Nobody reads your mail.
Does your current email make customers trust you more?
30 minutes: team size + current mail provider + goals. Plan + price + launch date.
