Everything you need to automate outreach
WhatsApp and Email — managed from one dashboard. Built for sales teams, marketers, and entrepreneurs who want to reach more people without the manual effort.
Bulk WhatsApp Messaging
Send personalized messages to thousands of leads at once via the official Meta Business API. Variable substitution makes every message feel one-on-one.
Bulk Email Campaigns

Smart Campaign Scheduling
Schedule WhatsApp and email campaigns in advance or set recurring sends — daily, weekly, or monthly. Set it once and never miss a follow-up.
Lead & Group Management
Organize contacts into groups, import via CSV, filter by status. One contact database feeds both your WhatsApp and email campaigns.
Rich Message Templates
Build reusable templates with dynamic variables for WhatsApp (Meta Business API) and email (HTML + plain text). One template library, every channel.
Two-Way Chat Inbox
Receive and reply to inbound WhatsApp messages in a unified inbox. Full conversation history, unread badges, and fast replies.

Built by founders
who felt the pain
OneToMany started in 2026 when our founders were spending hours copy-pasting WhatsApp messages to leads, losing track of follow-ups, and watching deals fall through the cracks — not because the product was bad, but because the outreach was broken.
We searched for a tool that combined WhatsApp and email automation in one place, with real personalisation and real tracking. It didn't exist. So a small team of founders and engineers built it — and OneToMany was born.
Democratise outreach automation for every business
Powerful outreach tools used to be reserved for enterprise teams with big budgets. Our mission is to put that same capability in the hands of every small business, agency, and solo founder — so you can reach more leads, follow up automatically, and grow without burning out.
The outreach backbone for 100,000+ businesses worldwide
We envision a world where any business — no matter its size or location — can run professional, personalised WhatsApp and email outreach at scale. We're building towards being the infrastructure layer that powers outreach for hundreds of thousands of teams globally.
