Use our free Email Deliverability Checker tool: Check Your Score Now

What is Email Deliverability Score?

Your email deliverability score measures how likely your emails are to reach the inbox (not spam).

It's based on:

  • DNS authentication records (SPF, DKIM, DMARC)
  • Mail server configuration (MX records)
  • Blacklist status (is your server flagged as spam?)
  • Sender reputation
  • Email engagement rates

A low score means your emails get blocked or filtered to spam.

A high score means inboxes welcome your emails.

How to Check Your Email Deliverability Score

Step 1: Use Our Free Tool

Go to PureMail Email Deliverability Checker.

Enter your domain or email address.

Click "Check Deliverability."

Step 2: Review Your Score

You'll get a score out of 95 points:

  • 85-95: Excellent - Your emails should reach inboxes
  • 70-84: Good - Minor improvements needed
  • 50-69: Fair - Several issues to address
  • 30-49: Poor - Major problems affecting deliverability
  • 0-29: Critical - Emails likely going to spam

Step 3: Check Individual Components

Our tool tests 5 critical areas:

1. SPF Record (20 points)

What it is: Sender Policy Framework - lists which servers can send email for your domain.

Why it matters: Without SPF, anyone can impersonate your domain.

Example SPF record:

v=spf1 include:_spf.google.com ~all

How to add it: Add a TXT record to your domain's DNS:

  • Record type: TXT
  • Host: @ (or your domain)
  • Value: Your SPF record

2. DKIM Record (20 points)

What it is: DomainKeys Identified Mail - adds a digital signature to your emails.

Why it matters: Proves emails weren't tampered with in transit.

How to set it up:

  1. Generate DKIM keys through your email service provider
  2. Add the public key as a TXT record in DNS
  3. Configure your mail server to sign outgoing emails

Most email services (Gmail, Outlook, SendGrid) provide step-by-step instructions.

3. DMARC Record (20 points)

What it is: Domain-based Message Authentication - tells email providers what to do if SPF/DKIM fail.

Why it matters: Protects your domain from phishing and spoofing.

Example DMARC record:

v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.com

Policy options:

  • p=none - Monitor only (start here)
  • p=quarantine - Send suspicious emails to spam
  • p=reject - Block suspicious emails entirely

4. MX Records (20 points)

What it is: Mail Exchange records - specify which servers receive email for your domain.

Why it matters: Without MX records, you can't receive emails.

How to check: Our tool shows your MX records with priority numbers.

Lower priority number = higher importance.

5. Blacklist Status (15 points)

What it is: Checks if your mail server's IP is on spam blacklists.

Blacklists we check:

  • Spamhaus ZEN
  • SpamCop
  • Barracuda
  • SORBS

Why it matters: Being blacklisted means your emails get automatically blocked.

How to get delisted:

  1. Identify why you were blacklisted
  2. Fix the issue (stop sending spam, secure your server)
  3. Request removal from each blacklist's website

How to Improve Your Deliverability Score

Fix DNS Records

If SPF is missing:

  1. Go to your DNS provider
  2. Add a TXT record with your SPF policy
  3. Wait 24-48 hours for DNS propagation
  4. Re-test with our tool

If DKIM is missing:

  1. Contact your email service provider
  2. Follow their DKIM setup instructions
  3. Add the provided DNS records
  4. Verify with our tool

If DMARC is missing:

  1. Create a DMARC policy (start with p=none)
  2. Add TXT record: _dmarc.yourdomain.com
  3. Monitor reports sent to your rua address
  4. Gradually increase to p=quarantine or p=reject

Get Off Blacklists

Check each blacklist:

  • Spamhaus: https://www.spamhaus.org/lookup/
  • SpamCop: https://www.spamcop.net/bl.shtml
  • Barracuda: https://barracudacentral.org/rbl/removal-request

Common reasons for blacklisting:

  • Sending to purchased email lists
  • High spam complaint rates
  • Compromised server sending spam
  • No authentication records

Delisting process:

  1. Fix the root cause
  2. Submit removal request
  3. Wait 24-48 hours
  4. Check again with our tool

Improve Sender Reputation

Beyond DNS records, focus on:

Engagement:

  • Send to engaged subscribers only
  • Remove inactive users regularly
  • Segment your list for relevance

Content:

  • Avoid spam trigger words ("FREE," "ACT NOW," "LIMITED TIME")
  • Use a recognizable sender name
  • Include a clear unsubscribe link

Sending practices:

  • Warm up new IP addresses gradually
  • Don't send huge batches at once
  • Maintain consistent sending volume

Why Email Deliverability Matters

For businesses:

  • 21% average open rate for cold emails
  • 99% of users check email daily
  • Email ROI: $36 for every $1 spent

Low deliverability = lost revenue

If 50% of your emails go to spam:

  • You're losing half your potential customers
  • Your email list is wasting money
  • Your campaigns aren't profitable

High deliverability = more revenue

95% inbox placement means:

  • More opens and clicks
  • Higher conversion rates
  • Better ROI on email marketing

Common Deliverability Myths

Myth 1: "I don't need SPF/DKIM/DMARC if I use Gmail"

False. Gmail configures SPF and DKIM for Gmail accounts, but you need DMARC.

If you send from a custom domain (hello@yourcompany.com), you need all three.

Myth 2: "My emails don't go to spam, so I'm fine"

Your test emails might not, but:

  • Different recipients have different filters
  • Inbox placement varies by provider
  • Spam filters learn over time

Test with our tool to be sure.

Myth 3: "Blacklists only affect spammers"

False. Legitimate businesses get blacklisted:

  • Compromised accounts
  • Employee mistakes
  • Shared hosting IP issues
  • Aggressive email campaigns

Check your blacklist status regularly.

How Often Should You Check?

Monthly: If you send emails regularly

Weekly: If you're running email campaigns
