Domain

Configure your portal's subdomain or custom domain

Subdomain

Your subdomain is set when your account is created and cannot be changed.

Custom Domain Studio plan

Add your own subdomain (e.g. clients.yourdomain.com), then point its CNAME record to cname.vercel-dns.com. We'll provision it and verify it automatically.

Email Sending Domain

Send proposals, invoices, and other client emails from your own domain instead of Kwill's

Your domain

We'll give you DNS records to add. Once they verify, emails to your clients will come from noreply@yourdomain.com instead of the shared Kwill domain.

Answers from our help docs
Why should I send emails from my custom domain?
Sending client notifications from your own custom domain (e.g. you@yourbrand.com) builds brand authority, avoids generic "via usekwill.com" headers, and significantly improves email deliverability by bypassing spam filters.
How does self-serve Resend DNS verification work?
In Kwill Settings, enter your custom domain. Kwill provides 3 DNS records (DKIM TXT, SPF TXT, and Return-Path CNAME). Add them to your domain host (Cloudflare, Namecheap, GoDaddy, etc.) and click Verify.
