Generated reports
Verify the customer email before showing an AI analysis, estimate, audit, color report, PDF, or saved result. When they return later, send another code to the same inbox and reopen the report.

Email codes for things people need to reopen.
Send a one-time code before showing a generated report, private album, file, list confirmation, portal, or login flow. The code stays stable for 10 minutes, so returning visitors can get back to the thing they asked for.
一
What is it?
Short answer: An email access code is a one-time password sent to an inbox before unlocking a specific action or piece of content. It is useful when you need email ownership, but a full account would add friction.
That makes it a fit for customer reports, private galleries, downloads, email lists, lightweight portals, and the normal auth flows people already associate with OTPs.
二
Use cases beyond login.
Treat the email inbox as the access key for a specific thing: a saved result, a file, a gallery, a list, or an account session.
Email lists
Confirm that a subscriber controls the inbox before adding them to a newsletter, launch list, referral list, community waitlist, or private announcement feed.
Private photos
Protect galleries for events, clients, families, creators, and teams without making every viewer create a full account.
Downloads and files
Gate a file, lead magnet, invoice, certificate, template, or attachment behind a code sent to the email address that requested access.
Client portals
Let customers reopen a lightweight portal, order status page, booking, quote, or shared workspace with just their email and a fresh code.
Login and verification
Use the same API for passwordless login, signup verification, high-risk action confirmation, and fallback magic codes.
Email-gated report access.
For a generated report, the product promise is not a login wall. It is a quick way for the customer to get a code and reopen the report.
- Ask for the email address when someone wants to view or return to private content.
- Send an OTP with a purpose such as report-access, album-access, list-confirmation, or file-download.
- Verify the code before revealing the report, gallery, download, list confirmation, or portal.
- If the visitor clicks resend during the 10-minute window, return the same code instead of creating a confusing new one.
No account wall required.
Use email OTPs when you need a real inbox, repeat access, and less friction than a password reset or a full user account.
Questions people ask
What is an email access code?
An email access code is a short one-time code sent to an inbox before showing private content or completing a workflow. It proves the visitor controls the email address without requiring a password.
How do email access codes work for generated reports?
Store the generated report under your own report ID, then use sendotp.email to verify the customer's email before opening that report. When the customer comes back later, verify the same inbox again and show the saved report.
Is this only for SaaS login?
No. Login is one use case, but email OTPs are also useful for email lists, private galleries, downloadable files, client portals, generated reports, RSVP confirmation, and lightweight customer access.
Why should the same code stay stable for 10 minutes?
People often refresh, resend, switch tabs, or search their inbox. A stable 10-minute OTP means the latest email does not invalidate the code they are already looking at.
