Email verification—only invited inboxes get the code

The English experience does not use SMS. Instead you can require an email one-time code, delivered only to addresses you list. Good for proposals, board packs, and partner docs where “anyone with the link” is too open.

No SMS Allowlisted emails Works with link or QR
Only specified emails can receive verification

Recipient experience

1. Open link or scan QR

They land on the reader gate as usual.

2. Enter allowed email

If the address is not on your list, no code is sent—forwarding the raw URL is not enough.

3. Paste OTP

After verification they can read within the limits you set (time, opens, SecureView, etc.).

Pair with Telegram

For English workflows you can also enable Telegram read alerts so you know when verified opens happen.

Email verification before reading
Verify before the document renders

FAQ

Is this the same as the Chinese SMS flow?

No. English pages and screenshots should describe email OTP, not phone SMS.

Can I mix public and gated links?

Yes—create separate entries: one open for marketing, one email-gated for partners.
