About
Postage.to is a web-based global letter delivery service that lets users send real physical mail from anywhere by uploading a document or writing a letter in an online editor, entering the recipient’s address, and letting the platform handle printing, stamping, enveloping, and postal delivery without trips to the post office or printing equipment. It simplifies international letter sending by making it as easy as sending an email; you compose or upload a letter, choose a destination in over 190 countries, pay per letter with no subscription requirement, and the system prints and mails it on your behalf, with real-time tracking from creation to delivery. Postage.to’s process is streamlined for speed and convenience, typically under five minutes from start to send, and prioritizes security and privacy by encrypting letters and deleting them after print, while offering customization options like fonts, formatting, and image support in the editor.

About
SecondFactor is a cloud service for generating, sending, and verifying one-time passcodes (OTPs) for account sign-up, login, and other phone-verification workflows. Product and engineering teams integrate it through an API and SDKs for Kotlin, Swift, Dart, TypeScript, and server-side development, then manage authentication templates from a dashboard. For each OTP, its Price Intelligence Engine selects the lowest-cost eligible channel based on destination pricing and recipient eligibility. If delivery is not confirmed within eight seconds, automatic fallback tries the next eligible channel. SecondFactor supports SMS, WhatsApp, Viber, and RCS, subject to destination, recipient, and account setup. Delivery logs show the destination, channel, status, and cost for each request. The service handles OTP generation, delivery, and verification so teams can add phone verification to their applications and manage delivery across multiple channels and markets.
