White label
Your product, end to end — no SignNow in sight
Your logo. Your colors. Your email copy. A white label electronic signature your users will swear you built yourself.
Every surface. Every touchpoint. Branded.Build signing that feels like part of your product
SignNow disappears. Your brand doesn't.
Logos, colors, fonts — all yours
Configure your brand once through the custom branding esignature api or admin console. Primary color, secondary color, logo, font family, rounded corners on buttons. Every signer sees your brand.
Branded email notifications
Customize the subject, body, logo, and message of every notification email, invites, reminders, and completion alerts, so signers see your branded esignature platform, not SignNow's.
Control the full signing experience
Customize the welcome pop-up, the signing session UI, and the post-signing redirect so the whole flow looks and feels like it was built by you, not licensed from someone else.
Multiple brand profiles, per invite
Create multiple brand configurations including logo, color scheme, email copy and apply a different one to each invite. Handy for multi-tenant platforms where each customer has their own private label esignature look.
Ship your brand in four steps

Our user reviews speak for themselves
We built everything off the API documentation that SignNow provides and some back and forth with support. It's taken us about two months to achieve this level of implementation with SignNow, and the system has been very reliable.
I integrated SignNow, and after working with their customer success team, I knew I made the right decision. I like the direction the company is going in and the way they show up for us, so I'm stoked to continue working with SignNow.

Frequently asked questions
Common questions about white label eSignature.
What does white label actually cover?
White label document signing software covers the signer-facing signing experience inside an embedded iframe, the visual branding of the signing UI (logo, colors), and the content of outgoing notification emails (subject, message, logo). Custom signing domains and custom sender email domains aren't supported today — emails always go from the SignNow domain.
Does the signing page show a SignNow URL?
When you embed signing inside an iframe or open it in your app, the signing URL isn't visible to the signer — they only see your product. For external (email) invites, the signing page is hosted by SignNow but fully themed with your branding.
Can I vary branding per customer?
Yes. If you're building a multi-tenant platform, every account can have its own brand profile including logo, color palette, and email content. Apply a different brand configuration per invite via the branded esignature api.
Is the audit trail also white-labeled?
The legal audit trail retains SignNow's certification data, which is required for compliance. But the PDF can be presented under your brand, and the content of every email touchpoint is fully customizable.
Which features require a Trial or paid plan?
Some advanced capabilities including webhooks and brand configurations require a Trial or paid plan. The Trial includes 250 credits for testing, so you can exercise these features end to end before committing to a plan.
