The most common mistakes when it comes to domains:
- Owning the domain through the domain email itself (i.e. owning brixwork.com with ownership through firstname.lastname@example.org - if the domain is expired or broken, there's no way to troubleshoot or receive emails since the entire email will most likely also crash)
- Letting it expire due to lack of communication with the registrar - register under an old email and then forgetting about it.
- Own the domain through an independent 3rd party email such as @gmail.com, or @yahoo.com - an email you will always have access to no matter what happens to the domain.
- Always keep all domains under one registrar (such as Namecheap.com or Godaddy.com - the more providers, the more confusing it can get).
- Keep your login information safe, and always use the same email as mentioned above. If you misplace your password, at least you can reset it by email verification.
- Check your domain records regularly, and even after getting your new email set up under your domain (such as email@example.com) check your registration email frequently enough (we have a separate @gmail under which all domains are owned).
