About

BulkChecker is a B2B contact verification and data quality platform for teams that need to clean phone number and contact lists before outreach, CRM updates, or messaging workflows. Users can upload CSV or TXT files, run bulk phone validation, carrier lookup, WhatsApp, Telegram, Viber, and other messaging-app checks, then export structured results for cleaner segmentation and operations. The platform supports no-code batch uploads and API-based verification workflows. BulkChecker helps identify invalid, unreachable, duplicate, recycled, or incorrectly formatted numbers, and provides useful signals such as carrier, line type, registration status, and active indicators where available. It is designed for growth, sales, marketing, data operations, and fraud-prevention teams that need faster list cleaning and more reliable contact data at scale.

About

Termii is an AI-native signal reliability platform that helps businesses guarantee critical customer transactions by evaluating SMS, WhatsApp, voice, and email simultaneously, then routing each message to the highest-confidence channel for that signal, moment, and customer. It is built for OTPs, fraud checks, transaction alerts, authentication, verification, and customer engagement that must arrive quickly and securely. Termii’s API platform makes communication functionality available to businesses of any size, allowing teams to add SMS, group messaging, voice, WhatsApp, and email into products or applications in just a few minutes. Its Token API helps prevent fraud before it occurs by generating and verifying one-time passwords sent to customers’ mobile devices, while the Switch API allows businesses to send messages globally across SMS and WhatsApp through a REST API.
