For many years, I kept my portfolio at around 500 domain names. It was easy to manage those domain names on the sales platforms I used. During the past several years, I made a conscious effort to grow my portfolio, which gives me more consistent sales. The downside is that it is a bit more work to manage my 2,500-strong portfolio of domain names.
Because many of the inventory-quality domain names I buy are essentially lottery tickets, I have been letting more of these domain names expire. If I have owned a domain name for many years without any inquiries and the metrics don’t look nearly as good as when I bought it, there’s a good chance I will let it expire. Those domain names will be replaced by better domain names.
Keeping my sales portfolios updated at Afternic, Sedo, and now Spaceship is a growing challenge. If I am away from my laptop when a final expiry email arrives in my inbox, there’s a chance I will forget to remove it from sales platforms. These platforms sometimes delete my domain names – or remove them from live listings – if they detect an expiration. This is definitely not failproof.
I’ve been concerned with accidentally selling a domain name I let expire, so I have done my best to be vigilant about keeping my portfolio listings updated. One suggestion I have for others is to get portfolio expiration reports at your main registrar on a monthly or quarterly basis. Take the list of domain names you let expire and search for them within your account on sales platforms. Doing this will help you identify listings of domain names that you previously let expire. You can then delete those active listings.
With Whois privacy now the default at various registrars and expiry auctions adding additional registration years, sales platforms don’t always detect an expiration or Whois change. This makes it quite possible for an expired domain name to remain listed for sale on a platform. There aren’t many worse feelings than seeing a name get sold, searching for the domain name, only to realize it expired and is owned by someone else. The sale can usually be unwound, but it’s embarrassing at best and potentially a way to get in some trouble with the platform at worst.
Mistakes and oversights happen, but getting registrar expiration reports and using those to ensure expired domain names are deleted can be a helpful way to keep portfolios correctly listed on third party platforms.

An EXCELLENT READ Elliot. And fertile ground for probably most of us “Domain Junkies”. “There aren’t many worse feelings than seeing a name get sold, searching for the domain name, only to realize it expired and is owned by someone else.” Been there, done that.
Thank you Elliot, for “what you do”
“Those domain names will be replaced by better domain names.”
Define “Better”
“my 2,500-strong portfolio of domain names.” How do you know it is “strong”
I have sold 44 domain names on Afternic alone this year with the smallest sale amount being $997. That alon would be a nearly 2% STR, which is pretty good. That doesn’t include any of my LTO sales at Afternic.
Beyond that, I have also had sales at Sedo. and Atom.
Beyond that, I have had private sales.
I think that would illustrate that my portfolio is strong.
I hand reg all my domains at 99cent and sold them for $2 or more and my ROI is 2000+%…. repeat repeat 100000 times….easy peasy
Remember to listen to BUllS song– it will make your day when your are feeling depress or feeling down ,when your domains are not selling
