Effess turns WhatsApp Web into a complete sales workspace — CRM, kanban pipeline, bulk sender with anti-ban pacing, scheduler, auto-reply, and AI assistant. Built for teams. Free, forever.
We didn't build another scheduler. We built the things competitors can't — fixing the bans, the busywork, the labels, and the typing.
Everything beyond the four superpowers above — a real CRM, a team inbox, a second official number, and the automation to run it all. One Chrome extension. Free to install, no login to start.
Your personal WhatsApp and a second Official Cloud-API number, unified on one screen. Reply to both — never switch tabs or devices again.
Reach your whole list with smart pacing — randomized delays, hourly caps, warm-up for new numbers, and an instant auto-pause the moment WhatsApp shows a ban-warning.
Drag-drop pipeline, tasks, reminders, lead scoring, full activity timeline — every chat becomes a deal you actually track.
Bulk-validate every number before you send. Zero wasted sends, and a sender reputation that stays clean.
Add teammates, auto-assign chats round-robin, and see at a glance who owns what.
Queue messages to fire at the perfect time — even with the WhatsApp tab closed.
Type / inside the WhatsApp composer to drop any saved template instantly.
Contacts and campaign logs flow into Sheets automatically — and back.
Webhooks for every event, plus native HubSpot, Salesforce & Zoho connectors.
One-click backup & restore that works even if your number gets banned. Your data is always yours.
Sends by day, top chats, deliverability.
Built-in. Zero setup.
No backend setup. No API keys (unless you choose AI). No team onboarding calls.
One click from the Chrome Web Store. The extension loads silently next to web.whatsapp.com — no account, no signup, no permissions ceremony.
A floating Effess panel docks onto your WhatsApp tab. Your existing chats, contacts, and groups are recognised instantly — everything stays local in your browser.
Import a list, draft a message with templates and variables, set safe pacing, and hit send. Watch the live queue, track delivery, get notified on completion.
Real reviews from real Effess users. No paid endorsements.

Effess is built on the principle of no gating. No license keys, no trial timers, no ‘Pro’ tier hiding the good stuff.
Effess will always have a free, fully-featured tier. The Teams tier is purely optional — pay only if you want shared cloud-sync or to support development.
Yes — fully free, no trial, no feature gating. We may add an optional paid Teams tier later for cloud-sync and CRM integrations, but the core 12 features stay free forever.
Free. No login. Works on any WhatsApp number. Install in 10 seconds, see results in your first hour.
