Why Custom Domains Win Deals
First impressions close contracts. When your signing pages live on your domain, clients trust faster and sign sooner.
Instant Trust
Clients see your domain in the URL bar, not a third-party. Trust goes up. Hesitation goes down.
Full White-Label
Your domain, your logo, your SMTP. Recipients never know MamaSign exists. It looks 100% yours.
Brand Consistency
Every touchpoint — emails, signing pages, invoices — reinforces your brand instead of diluting it.
Professional Edge
sign.yourfirm.com signals you invest in your tools. That credibility wins enterprise clients.
Everything You Need. Nothing You Don't.
Enterprise-grade custom domain infrastructure — included in your one-time payment. No add-ons. No per-domain fees.
Auto SSL Provisioning
HTTPS from minute one. We provision and renew your SSL certificate automatically. Your clients always see the green padlock.
Universal Link Rewriting
Signing pages, invoice links, and sharing URLs all rewrite to your custom domain. One setting, every link updated.
Multiple Domains
Add as many domains as you need. Set one as primary. Switch anytime. Each domain gets its own SSL and verification.
DNS Verification
CNAME or TXT record — pick the method your DNS provider supports. Live detection retries automatically until verified.

Custom Domains Shouldn't Cost Extra
