Domain Setup and DNS Records for Your Landing Pages

Setting up a custom subdomain lets you serve your landing pages from your own branded URL (for example, app.yourdomain.com) instead of the default LeadCenter domain.

Requirements

• An active subscription (or an offline / LeadCenter plan) is required to generate SSL certificates.
• SSL certificates are generated only for custom domains, not default LeadCenter domains.

How to Set Up

1. Enter your subdomain: Go to Marketing → Domain. Enter your full subdomain, such as app.yourdomain.com, and save it.
2. Create the landing page CNAME record: At your domain provider (GoDaddy, Cloudflare, Namecheap, and others), create a CNAME record pointing your subdomain to us-domain.leadcenter.ai.
   • Type: CNAME
   • Name: your subdomain or host name, depending on your DNS provider
   • Value: us-domain.leadcenter.ai
   • TTL: Auto
3. Wait for the SSL validation record to appear: After saving your domain in LeadCenter, a separate SSL certificate validation CNAME record appears on the page, usually within about 30 seconds.
4. Add the SSL validation CNAME record: Copy the exact Name and Value shown on the page and add that record to your DNS provider.
5. Wait for certificate validation: Once AWS validates the record, your certificate status changes to Issued and your landing pages are secured with HTTPS.

Important: If your DNS provider offers proxy settings, add the SSL validation CNAME record with Proxy set to DNS only.

Certificate Status

• Pending — the certificate has been requested and is waiting for DNS validation
• Issued — the certificate is active and your custom domain is secured with HTTPS
• Timed Out — the validation record was not added within 72 hours
• Failed — the certificate request failed

Reissuing a Certificate

If the certificate shows Timed Out or Failed, a Reissue Certificate button appears. Clicking it requests a new certificate. If your DNS validation record is already in place, the new certificate can validate automatically without any additional DNS changes.

LeadCenter also attempts to reissue timed-out or failed certificates automatically during nightly maintenance.

Important Notes

• The SSL validation CNAME record must be added within 72 hours of certificate creation, or the certificate request will time out.
• DNS changes can still take time to propagate depending on your provider.
• If you change your landing page domain later, LeadCenter automatically requests a new certificate for the new domain.
• If you switch back to a previous domain, LeadCenter can reuse the earlier certificate when available.
• Each domain and account combination has at most one active certificate at a time.

Troubleshooting

• The SSL validation record is not showing yet: Wait about 30 seconds after saving the domain, then refresh the page.
• My certificate is still pending: Confirm that you added the SSL validation CNAME exactly as shown on the page.
• My certificate timed out: Click Reissue Certificate. If your DNS record is already correct, the new request may validate automatically.
• My landing page is not loading on the custom domain: Make sure both the main landing page CNAME and the SSL validation CNAME were added correctly.

Frequently Asked Questions

• Do I need to contact support to install SSL? — No. SSL certificate creation and validation are handled automatically. You only need to add the DNS records shown on the page.
• How long does SSL validation take? — Once the DNS record is added, validation usually finishes within minutes to a few hours.
• What if I change my subdomain later? — LeadCenter requests a new certificate for the new domain automatically.
• Why is my certificate not being generated? — Make sure you have an active subscription and that you are using a custom domain instead of a default LeadCenter domain.
