InboxRhino vs Tigrmail
Both are receive-only APIs for automated tests. Choose InboxRhino when you want a sandboxed HTML mailbox, named API keys, and INR/GST billing designed for Indian teams. Choose Tigrmail when you already have that workflow and do not need those extras. Confirm current Tigrmail behaviour on tigrmail.com.
Who each product fits
InboxRhino is for Playwright/Cypress suites, agentic QA, and Indian SaaS teams that need a real MX address, visual debugging, and later GST invoices. It does not send mail, extract OTPs for you, or offer an SDK in v1.
Tigrmail is also a temporary receive-inbox API aimed at end-to-end email verification. If visual QA, key rotation, or INR invoicing are not requirements, it may already cover the wait-and-assert loop.
