Frequently Asked Questions
Can I use both WhatsApp and email for the same client?
Absolutely. Many businesses use email for formal documentation and contracts, then WhatsApp for quick day-to-day coordination. The key is consistency. With a unified inbox, you can see both channels side-by-side and switch seamlessly without losing context.
Does WhatsApp have the same legal standing as email?
In most jurisdictions, WhatsApp messages are legally admissible, but email is generally preferred for formal agreements. For contracts, proposals, and anything requiring a clear audit trail, send via email. WhatsApp is better for discussions leading up to those formal documents.
Which channel has better engagement rates?
WhatsApp typically sees 98% open rates vs email's 20-25%. However, engagement depends on context. A well-crafted email to the right person can outperform a WhatsApp blast. For sales outreach, test both channels and measure response rates in your CRM.
How do I train my team on channel selection?
Create a simple decision framework: "If urgent or requires a quick answer, use WhatsApp. If formal, detailed, or needs documentation, use email." Then use a unified inbox so the team can handle both channels efficiently from one dashboard.
Can AI help choose the right channel for each message?
Yes. Dew, the AI assistant in Dewx, analyzes conversation context and can suggest the optimal channel. For example, it might recommend switching to email for a detailed proposal after a WhatsApp discovery call.
