Overview

Cloom AI uses SendGrid to send authenticated emails on your behalf. This guide walks you through configuring your domain to send emails through Cloom AI.

​
Prerequisites

Before you begin, you’ll need:
  • Access to your domain’s DNS settings (GoDaddy, Namecheap, Google Domains, etc.)
  • A dedicated email address or subdomain for sending
  • Administrative access to your Cloom AI account

​
Choosing Your Sending Domain

Important: Do not use your root domain (e.g., [email protected]) as your sending address.Cloom AI will be able to intercept all emails sent to that domain. For example, if you set up [email protected], Cloom can read all emails sent to *@company.com.
Best Practice: Use a subdomain[email protected] (e.g., [email protected])This isolates your AI email handling from your main domain.
Alternative: Create a dedicated domain[email protected] (e.g., [email protected])This provides complete separation from your primary domain.

​
Step 1: Access Email Configuration

  1. Navigate to Settings from the main menu
  2. Click Email Sending tab
  3. Click Outbound section
  4. Click + Create Sending Configuration
Email sending configuration

​
Step 2: Create Sending Configuration

Enter your email details:
​
Sending Email Address
string
required
The complete email address you want to send fromExample: [email protected]
​
Verified Domain
string
required
The domain name (extracted automatically from your email address)Example: elegi.cloom.ai
​
SendGrid Subdomain
string
required
A subdomain prefix for email authentication (usually your brand or “mail”)Example: s1

​
DKIM and SPF Configuration

Cloom AI automatically manages SPF and DKIM email authentication to improve deliverability and prevent spoofing.
Check the box to enable:
  • ✅ Enable Automatic SPF/DKIM Management (Recommended)

​
Step 3: Add DNS Records

After creating your sending configuration, you’ll receive DNS records to add to your domain: DNS records for email authentication

​
DNS Record Types

You’ll need to add three types of CNAME records:
1

Domain Verification Record

Type: CNAMEHost/Name: s1._domainkey.elegiValue: Provided by Cloom AIPurpose: Verifies domain ownership
2

DKIM Authentication Records

Type: CNAME (2 records)Host/Name: s1._domainkey and s2._domainkeyValue: Provided by Cloom AIPurpose: Email authentication and deliverability

​
Step 4: Update Your DNS Provider

The exact steps depend on your DNS provider:

​
Example: Adding CNAME Records

Most DNS providers follow a similar pattern:
  1. Log in to your DNS provider (GoDaddy, Namecheap, Cloudflare, etc.)
  2. Navigate to DNS management for your domain
  3. Click Add Record
  4. Select CNAME as record type
  5. Enter the Host/Name from Cloom AI
  6. Enter the Value/Points To from Cloom AI
  7. Set TTL to Automatic or 3600
  8. Save the record
  9. Repeat for all CNAME records
Example DNS configuration

​
Common DNS Providers

  1. Go to DNS Management
  2. Click “Add” under Records
  3. Select “CNAME” type
  4. Enter Host and Points to values
  5. Click “Save”
  1. Go to Advanced DNS
  2. Click “Add New Record”
  3. Select “CNAME Record”
  4. Enter Host and Target values
  5. Click “Save Changes”
  1. Go to DNS settings
  2. Click “Add Record”
  3. Select “CNAME”
  4. Enter Name and Target
  5. Toggle proxy status to “DNS only”
  6. Click “Save”
  1. Go to DNS settings
  2. Scroll to Custom Records
  3. Select “CNAME” type
  4. Enter Host name and Data
  5. Click “Add”

​
Step 5: Verify Configuration

DNS changes can take 30-60 minutes to propagate. Once the DNS has propagated:
  1. Return to your email configuration in Cloom AI
  2. Click the Verify button
  3. Wait for confirmation that records are validated
✅ Success! Your domain is now verified and ready to send emails.

​
Verification Failed?

If verification fails:
  • Wait longer: DNS propagation can take up to 48 hours
  • Check records: Ensure CNAME records were entered exactly as provided
  • Remove extra characters: Some DNS providers add the domain automatically; avoid duplication
  • Contact support: Reach out to your Cloom AI representative for assistance

​
Testing Email Sending

Once verified, test your email setup:
  1. Create an outbound email node in a workflow
  2. Add a test recipient email address
  3. Send a test email
  4. Check that it arrives and is not marked as spam

​
Troubleshooting

  • Verify all DNS records are correctly configured
  • Check that SPF/DKIM are passing (use a tool like mail-tester.com)
  • Ensure your sending domain has a good reputation
  • Add an unsubscribe link to your emails
  • Double-check for typos in CNAME records
  • Ensure you didn’t include quotes in the values
  • Verify the subdomain prefix matches your configuration
  • Contact your DNS provider’s support if needed
  • Some hosts don’t allow CNAME records on root domains
  • Try using a subdomain instead
  • Check if your DNS provider has specific formatting requirements

​
Best Practices

Use Subdomains

Always use a subdomain or separate domain for AI email handling

Monitor Reputation

Keep an eye on your email deliverability and bounce rates

Warm Up Domain

Start with low volume and gradually increase to build reputation

Test Regularly

Send test emails to different providers (Gmail, Outlook, Yahoo)
