About OTPINB

Last updated 2026-11-03

OTPINB is a temporary email service maintained by the OTPINB Team. It gives you a separate address for short-term tasks and authorized email testing, with a workspace for managing several inboxes when you need more than a single address.

What you can do here

Use Quick Inbox to read an eligible public mailbox by its full address. Sign in to manage your mailboxes, link Telegram notifications, or use Balance to purchase Credits and prepaid Premium membership. Premium adds workspace capacity, longer message retention and access to member domains; the current benefits and limits are on Pricing.

Receiving mail and sending mail have different requirements. Sending depends on the address's permissions and available Credits. Shared account Credits can be used through the supported account workflow. Buying Premium does not grant unlimited sending.

Public means public

New mailboxes created under our public-mailbox configuration can be read by anyone who knows the full address. Premium membership does not make these inboxes private. Avoid sensitive messages, important account recovery and anything that requires exclusive access. Temporary email also cannot guarantee that another website will accept an address or deliver a message.

Practical guidance

Our Guides explain verification messages, inbox lifetimes, public access and multi-inbox workflows. They are written under the OTPINB Team byline and describe the service's actual behavior. Examples and illustrations use synthetic data rather than customer messages.

The project builds on the open-source Cloudflare Temp Email project, with OTPINB-specific account, quota, membership, payment and Telegram extensions. An upstream project or infrastructure provider does not operate or endorse every OTPINB feature.
