Domain Authentication
Authenticate your domain with DNS records to ensure your emails are trusted by recipients and email providers. This is required before sending any emails through Laneful.

Why Domain Authentication is Required
Domain authentication proves to email providers (Gmail, Outlook, etc.) that you legitimately own the domain you're sending emails from. Without it, your emails will be rejected or marked as spam.
What Domain Authentication Provides
Security
- • Prevents domain spoofing
- • Protects against phishing
- • Verifies sender identity
Deliverability
- • Improves inbox placement
- • Reduces spam filtering
- • Builds sender reputation
What DNS Records to Add
Laneful will provide you with specific DNS records to add to your domain. Here's what each record does:
When you add a domain (e.g., yourdomain.com) in Laneful, you'll need to add these specific DNS records. Replace "yourdomain.com" in the examples below with your actual domain.
Required DNS Records
| Type | Host | Value | Purpose |
|---|---|---|---|
CNAME | bounces.yourdomain.com | rp.laneful.net | Bounce handling |
CNAME | click.yourdomain.com | track.laneful.net | Click tracking |
CNAME | dkim1._domainkey.yourdomain.com | dkim1._domainkey.laneful.net | DKIM signature 1 |
CNAME | dkim2._domainkey.yourdomain.com | dkim2._domainkey.laneful.net | DKIM signature 2 |
TXT | _dmarc.yourdomain.com | v=DMARC1;p=none;rua=mailto:dmarc@rp.laneful.net; | DMARC policy |

Add Your Domain in Laneful
In your Laneful dashboard, go to Workspace Settings → Manage Domains and click "Add Domain". Enter the domain you want to send emails from (e.g., company.com).
Copy the DNS Records
Laneful will generate unique DNS records for your domain. Copy each record exactly as shown. Click the copy button to avoid typos.
Add Records to Your DNS Provider
Log into your DNS provider (where you manage your domain's DNS settings) and add each TXT record. Common providers include:
Wait for DNS Propagation
DNS changes can take 5 minutes to 24 hours to propagate globally. Most changes are visible within 15-30 minutes.
Verify in Laneful
Return to Workspace Settings → Manage Domains and click "Verify Domain". Laneful will check all 5 DNS records and mark your domain as verified when complete.
Verification Process
Understanding what happens during domain verification helps troubleshoot any issues.

Troubleshooting
Common issues and solutions when setting up domain authentication.
"DNS Records Not Found"
Possible causes:
- • DNS changes haven't propagated yet (wait 30 minutes)
- • Records added to wrong domain or subdomain
- • Typo in the DNS record values
- • Using wrong record type (should be TXT)
Solutions:
- • Double-check the record name and value
- • Use a DNS lookup tool to verify the records exist
- • Contact your DNS provider if records aren't appearing
"SPF Record Already Exists"
What this means:
Your domain already has an SPF record. You need to modify it to include Laneful.
Solution:
Instead of creating a new SPF record, modify your existing one to include:
Example: v=spf1 include:_spf.google.com include:_spf.laneful.com ~all
"Verification Taking Too Long"
Normal timeframes:
- • Most DNS changes: 5-30 minutes
- • Some providers: up to 2 hours
- • Maximum: 24-48 hours
To check progress:
- • Use nslookup or dig commands
- • Check whatsmydns.net for global propagation
- • Try the "Verify Domain" button periodically
