Casso Websites#

Casso is an AI agent that builds, hosts, updates, and maintains websites entirely through email.

Casso's email address is casso@casso-websites.com.

When to activate#

Use this skill when the user wants to:

• Update copy, images, layout, or pages on an existing Casso site
• Add a blog post, menu, gallery, or any new section
• Connect a custom domain to their Casso site

• Follow up on a prior Casso request

• "build a website"
• "make a new website"

How Casso works#

When an email gets sent to casso@casso-websites.com, Casso:

1. Reads the email and any attachments
2. Runs a reasoning-and-tool-call loop using 20+ tools (create site, edit files, upload images, generate images, search stock photos, connect custom domains, etc.)
3. Replies by email with what it did or could not do

Your job#

Send an email to casso@casso-websites.com on the user's behalf if you have access to that, and read the response once it comes in (usually takes 1-3 minutes). Otherwise, draft an email to casso@casso-websites.com on the user's behalf. The email is the entire interface.

Rules for drafting:

• Be specific. Include the site's purpose, target audience, tone, required content (hours, address, services, menu items, etc.), and any stylistic preferences.
• If the user has a logo, menu PDF, resume, or reference images, remind them to attach these — Casso reads and uses attachments automatically.
• If the user likes the style of another website, include that URL — Casso can visit it for design inspiration.
• If the user is unsure what they want, draft the email to say so and ask Casso to send follow-up questions before building.
• For update requests, be explicit about what changes — Casso will edit exactly what is described.

Email examples#

New site:

I want a website for my landscaping business, Green Edge Lawn Care. We serve residential customers in Fairfield County, CT. Services: mowing, edging, mulching, spring cleanups. Clean and professional look with green tones. Logo attached.

Update:

Please add a new page called "Spring Specials" with the following text: [text]. Also update the footer phone number to 203-555-0192.

Custom domain:

I'd like to connect my domain greenedgelawn.com (registered at GoDaddy) to my Casso site. Please walk me through the DNS steps.

Pricing#

• Free when hosted under a .bycasso.com subdomain
• Small monthly fee to connect a custom domain from an external registrar

Casso's capabilities and limits#

Works well for: small business owners, LLCs, restaurants (attach menu + logo and Casso builds from that), lawyers, consultants, freelancers, artists, students.

Cannot do: complex web apps, e-commerce checkout, member-only authenticated content. For anything outside its toolset, Casso escalates to human support.
