Understanding TXT Records

Learn how TXT records help verify domain ownership and configure email security

What is a TXT Record?

A TXT (Text) record is like a sticky note for your domain. It lets you attach any text information to your domain name, which can be used to prove ownership, configure email security, or provide information to other services.

Real-world examples:

# Google Workspace verification
example.com    →    "google-site-verification=1a2b3c4d5e6f7g8h9i0j"

# Email security with SPF record
example.com    →    "v=spf1 include:_spf.google.com ~all"

# Microsoft 365 verification
example.com    →    "MS=ms12345678"

# Domain ownership verification for various services
example.com    →    "facebook-domain-verification=1234567890"
example.com    →    "stripe-verification=abcdef123456"

# DMARC policy
_dmarc.example.com    →    "v=DMARC1; p=reject; rua=mailto:reports@example.com"

Simple Explanation

Think of TXT records like ID cards or badges for your domain:

Just like you might show your ID to prove who you are, your domain uses TXT records to prove itself to various services
Like having different badges for different buildings, you can have multiple TXT records for different purposes
Similar to how a badge might include special instructions, TXT records can contain specific configuration information

These digital "badges" help services verify your domain's identity and understand how to handle things like email security and domain verification.

Common Uses (With Examples)

✓
Email Security (SPF)
Tell email servers which servers can send email from your domain:
```
v=spf1 include:_spf.google.com include:_spf.microsoft.com ~all
```

✓

Service Verification

Prove domain ownership to various services:

google-site-verification=1234567890abcdef facebook-domain-verification=1234567890

✓

DMARC Policy

Set email authentication policies:

v=DMARC1; p=reject; rua=mailto:reports@example.com

Important Things to Know

•
Multiple Records Allowed
You can have many different TXT records for the same domain, each serving a different purpose.
•
Character Limits
Each TXT record has a length limit - very long records might need to be split into multiple parts.

Common Mistakes to Avoid

⚠️
Incorrect Formatting
Make sure to include quotes when required and follow exact formatting instructions from services.
⚠️
Deleting Important Records
Don't remove TXT records unless you're sure they're no longer needed - they might be essential for email or services.

Quick Tips for Success

✓
Document Your Records
Keep notes about what each TXT record is for and when it was added.
✓
Verify After Adding
After adding a TXT record, verify it's working using the service's verification tool.
✓
Regular Cleanup
Periodically review your TXT records and remove any that are no longer needed.
