What Onevyu connects — and what it does not
Official Meta APIs, messaging windows, email behavior, and clear limits — so you know before you connect channels.
In short
Official Meta APIs, messaging windows, email behavior, and clear limits — so you know before you connect channels. Onevyu is the Conversation CRM for integrations & limits — WhatsApp, Instagram, and Facebook DMs with pipeline, proposals, and invoices on one client record. Free during early access.
The problem
- Unclear whether personal WhatsApp or profile Instagram will work with business CRM tools
- Surprise Meta 24-hour messaging windows blocking follow-ups
- Products marketed for everyone but built for broadcast marketers
How Onevyu helps
- Clear Meta setup checklist: WhatsApp Business, IG Business + Page, FB Page
- Transparent messaging window and template rules for WhatsApp
- Email: reply in mail vs Resend for scheduled follow-ups
- Clear fit guide — who Onevyu is and is not for
Meta channel setup
Onevyu connects through official Meta APIs. You need WhatsApp Business assets in Meta Business Suite, an Instagram Business account linked to a Facebook Page, and a Facebook Page for Messenger. Personal WhatsApp and profile-only Instagram will not connect.
Messaging windows and templates
WhatsApp and Messenger allow free-form replies within Meta customer service windows — typically 24 hours after the client's last message. Outside that window, WhatsApp requires approved message templates. Onevyu automations are designed to stay within these rules.
Email behavior
Reply to clients by email from the thread when email is on the record. Scheduled email follow-ups use Resend for delivery — separate from live DM replies in the unified inbox.
Clear fit limits
Onevyu is not for broadcast marketers, personal WhatsApp-only users, or teams needing enterprise marketing suites. It is Conversation CRM for solopreneurs who close personally in DMs — and it's free during early access.
Common questions
What Meta assets do I need to connect?
WhatsApp Business via Meta Business Suite, an Instagram Business account linked to a Facebook Page you manage, and a Facebook Page for Messenger. Personal WhatsApp and profile-only Instagram cannot use official business messaging APIs.
What are Meta messaging window limits?
WhatsApp and Instagram/Facebook Messenger allow free-form replies within Meta's customer service windows (typically 24 hours after the client's last message). Outside that window, WhatsApp requires approved message templates. Onevyu automations respect these rules.
How does email work in Onevyu?
You can reply to clients by email from the thread when email is on the record. Scheduled email follow-ups use Resend for delivery — separate from live DM replies in the unified inbox.
Who is Onevyu not for?
Broadcast marketers sending mass campaigns, users on personal WhatsApp only, and teams needing enterprise marketing suites with paid-ads-to-landing-page workflows at scale. Onevyu is built for human-led DM sales for solopreneurs.
Does Onevyu collect client invoice payments?
No. Onevyu builds invoices and tracks status. Clients pay you directly; you can share optional payment links and mark invoices paid when payment arrives.
Is Onevyu free?
Yes, it's free during early access. Early testers get 6 months free when paid plans launch.
How long does channel setup take?
Guided setup in Connections usually takes about 15 minutes if you already have WhatsApp Business and Instagram Business linked to a Facebook Page.
