Communications | Kantos Docs

Kantos Communications provides a visual email builder, template management, and email logs to help you engage with contacts effectively. Design beautiful emails, personalize with variables, and track delivery.

Professional Emails, Zero Code

Create stunning, responsive emails with our drag-and-drop builder. No HTML knowledge required—just design, personalize, and send.

Sending Emails

Via Automation

The most common way to send emails is through automations:

{
  "type": "send_email",
  "config": {
    "template_id": "tmpl_welcome",
    "to": "{{record.email}}",
    "subject": "Welcome to {{org.name}}!",
    "from_name": "{{sender.name}}",
    "reply_to": "{{sender.email}}"
  }
}

Manual Send

Send emails directly from a record:

Open a Record

Navigate to the record you want to email.

Click "Send Email"

Find the email action in the record menu.

Select Template

Choose a template or compose from scratch.

Review & Send

Preview the personalized email and click send.

Email Logs

Track every email sent from your Kantos account:

Status	Description
Sent	Email successfully sent to mail server
Delivered	Email accepted by recipient's mail server
Opened	Recipient opened the email (tracking pixel loaded)
Clicked	Recipient clicked a link in the email
Bounced	Email couldn't be delivered
Complained	Recipient marked as spam
Unsubscribed	Recipient clicked unsubscribe

Email Tracking

Open and click tracking is enabled by default. You can disable it per template if needed for privacy-sensitive communications.

Domain Authentication

Improve deliverability by authenticating your sending domain:

Open Domains

Go to Communications → Domains in the sidebar.

Choose Your Domain

Enter the domain you send from (e.g., company.com). Kantos sends through a subdomain such as mail.company.com, so your existing email keeps working.

Add DNS Records

Copy the records into your DNS host: three for sending (required), MX for replies and a DMARC record (both recommended; v=DMARC1; p=none; is a safe start). Kantos detects common DNS hosts and shows their steps.

Create a Sender

DNS changes usually show up within minutes, but can take up to 48 hours. Kantos checks while the domain's page is open, and every 15 minutes in the background during a new domain's first week; after that, open the domain and click Check now. Once sending is verified, create your first sender and send yourself a test email.

Important for Deliverability

Without domain authentication, your emails may land in spam folders. Complete verification before sending to customers.

Setting This Up With an AI Agent

Kantos exposes an MCP (Model Context Protocol) server. Connect an AI agent — Claude or any other MCP client — and it can handle most of the flow above for you.

Connect Your Agent

As an org admin, go to API → MCP Integrations and connect your agent via OAuth.

Agent Registers the Domain

It calls domains_create, which returns the DNS records SendGrid needs.

You Add the DNS Records

This one step stays human — no agent can edit your registrar's DNS for you. Paste in the records it gave you.

Agent Finishes Setup

Once you confirm the records are in, it calls domains_validate to check propagation, then email_senders_create to add a sender and start sending.

What the agent can and can't do

domains_list, domains_create, domains_validate, email_senders_list, email_senders_create, and email_senders_check_verification cover the whole flow except one thing: actually adding DNS records at your registrar. That step has to stay with a human — the agent will tell you exactly what to add and pick up again once that is done.

Best Practices

Design

Keep subject lines under 50 characters
Use a clear, single call-to-action
Include your logo for brand recognition
Test on multiple email clients
Always include an unsubscribe link

Deliverability

Authenticate your sending domain (SPF, DKIM, DMARC)
Maintain a clean email list
Don't use spammy words in subject lines
Keep image-to-text ratio balanced
Monitor bounce rates and remove invalid emails
