Last seen? Just now—signing your document.
With WhatsApp being the go-to messaging app for billions worldwide, we figured it's only right to bring e-signing into the conversation. Now, you can send signature requests straight to your recipient's WhatsApp. Unlike emails that might sit unopened for hours (or even days), WhatsApp messages pop up front and center, so your documents don't wait—they get noticed.

Get message templates approved and ready to go
Zoho Sign sends your predefined WhatsApp message templates for approval; think of it as getting the double tick from WhatsApp itself. Once they're approved, you're all set to start sending documents.

Double ticks need double checks
Add an extra layer of "are-you-really-you?" by enabling OTP-based identity authentication. Recipients will receive a one-time password on WhatsApp before accessing the document, so only the right person can view and sign.

Available: WhatsApp delivery mode
Why stick to just email and SMS when you can level up? Head to Settings and enable Email + WhatsApp as your delivery method to start sending documents where people actually stay connected.
