How to track domain renewals for your clients

When a domain lapses, the website, email and every certificate on it go with it. Domains rarely expire because nobody cared. They expire because the renewal email went to someone who left, or the card on a registrar account nobody remembers had expired.

Why client domains slip

Where expiry dates come from

Don't rely on a spreadsheet you update by hand. Every domain's registration expiry is published by its registry. For generic top-level domains such as .com, .net and .org, RDAP (the Registration Data Access Protocol) is now the official way to look it up, replacing the old WHOIS service with structured, consistent data. Many country-code domains publish RDAP too; a few still only offer WHOIS or a web lookup, so record those dates by hand.

Reading the date from the registry, rather than the registrar's dashboard, also catches the domain you didn't know was registered somewhere else.

What happens after a domain expires

For most generic domains, expiry isn't instant loss, but each stage is more expensive and more disruptive:

StageTypical lengthWhat it means
Renewal graceVaries by registrar, often up to about 30 to 45 daysThe domain may stop resolving, but it can be renewed at the normal price.
RedemptionAbout 30 daysThe domain can still be recovered, usually with a significant redemption fee.
Pending deleteAbout 5 daysIt can't be recovered. Afterwards anyone can register it.

Country-code domains follow their own registry's rules, and some have much shorter grace periods. Don't plan on any of them.

A process that holds up

  1. Inventory every client domain, including the ones only used for email, redirects or old campaigns.
  2. Record the registrar and the account owner for each, and move accounts to a shared or client-owned login, never one person's email.
  3. Turn on auto-renew and multi-year renewals for anything important, and check the payment method on file.
  4. Watch the registry expiry date automatically, and alert a shared channel 30 and 14 days out, then daily in the final week.
  5. Keep certificates and domains on the same list. They fail together, and the same people fix them.
  6. Show the client. A quarterly renewal report makes it clear who renews what.

How Radardue fits

Radardue reads each domain's expiry and registrar from the registry over RDAP, keeps it next to the client's certificates and other renewals, and alerts your team by email, Slack, Discord, Telegram or webhook before anything lapses. For domains without RDAP, add the date as a renewal. How domain checks work, or explore the demo.
