Colorado Internet Domains

We build useful websites.

Colorado Internet Domains builds local websites and services that help Colorado people and businesses look established and get found.

So far that means two things: personal email addresses on your city's own .co domain, and Grass.co, a directory of Colorado's licensed dispensaries.

Email on your city's domain

Your name. Your city. One address.

Get an address like [email protected] on the domain that carries your city's name. It is a real Google Workspace mailbox, with calendar, drive and video calls. Pick your city, check that your name is free, and sign up on that city's site. Each city site shows its price before you check out.

Colorado dispensary directory

Grass.co

A directory of licensed cannabis dispensaries across Colorado, by city and by type. We check every shop against state records each month, so you are not driving to somewhere that has closed. Dispensary owners can add their shop. For adults 21 and over.

Who we are

We are two real people in the Denver metro area. Between us we have more than 70 years of experience growing our own businesses and helping other people grow theirs.

Kelly
A former magazine owner and a marketing professional.
Ross
A marketing and sales technologist.

We own these city domains so they stay useful to the people and businesses of Colorado, instead of ending up with a big corporation that sees them as one more thing to squeeze. A city's name should work for that city.

Seeing a charge from us?

Charges show on your statement as your city's domain followed by EMAIL, for example DENVER.CO EMAIL. It is for an email address on that city's domain.

Our promises

In plain words. Every one of these is in the Terms on each city site.

  1. There is only one of each name per city. While it is yours, nobody else can have it.
  2. Your mailbox is a real Google Workspace mailbox, with calendar, drive and video calls.
  3. We do not read, scan or store the contents of your email.
  4. We do not sell your personal information.
  5. The price you sign up at is locked for 2 years.
  6. You can cancel any time. If you leave, your mailbox stays open for 14 days so you can take your mail with you. It is deleted after 30 days, and your name is held for 180 days before anyone else can register it.

Policies

The same policies apply on every city site. You can read them on denver.co, or at /terms, /privacy and /aup on your own city's site.
