Email Deliverability Test - Ensure Your Emails Reach the Inbox

The Email Deliverability Test Tool by Hashe Tools helps you analyze how likely your emails are to reach recipients’ inboxes instead of being flagged as spam or rejected.

This test evaluates email authentication (SPF, DKIM, DMARC), server reputation, DNS configuration, and message headers to ensure maximum deliverability and sender trust.

What Is Email Deliverability?

Email deliverability is the ability of your emails to reach the recipient’s inbox successfully. It depends on key factors such as SPF, DKIM, DMARC authentication, IP reputation, content quality, and sender behavior.

Poor deliverability can result in legitimate messages being marked as spam or blocked entirely, affecting communication and campaign success.

Why Use the Email Deliverability Tool?

Our Email Deliverability Test provides in-depth diagnostics to help you maintain a high inbox placement rate:

• Analyze Authentication: Verify that your domain correctly implements SPF, DKIM, and DMARC.
• Check DNS Configuration: Ensure essential DNS records for mail routing and sender identity are properly set up.
• Evaluate IP Reputation: Detect if your sending IP address is blacklisted or marked as suspicious.
• Inspect Email Headers: See how receiving mail servers interpret your message headers.
• Improve Inbox Placement: Optimize your domain and server setup for consistent, spam-free delivery.

Key Factors Affecting Email Deliverability

• SPF Record: Defines authorized mail servers allowed to send on behalf of your domain.
• DKIM Signature: Ensures message integrity and authenticity using cryptographic signatures.
• DMARC Policy: Guides mail servers on how to handle messages that fail authentication checks.
• Reverse DNS (PTR): Confirms your sending IP aligns with your domain’s hostname.
• IP Reputation: Indicates how email providers like Gmail or Outlook rate your domain’s trustworthiness.
• Mail Content: Spammy wording, broken links, or poorly structured HTML can cause filtering.

Common Causes of Poor Deliverability

• Missing or invalid SPF, DKIM, or DMARC records.
• Sending from shared or blacklisted IPs.
• High bounce or spam complaint rates.
• Misleading from names or reply-to addresses.
• Sending from a new domain without an established reputation.

How to Improve Email Deliverability

• Authenticate all outgoing emails with SPF, DKIM, and DMARC.
• Gradually warm up new IP addresses to build trust.
• Maintain a clean mailing list, remove invalid or inactive addresses.
• Use consistent “From” names and recognizable branding.
• Monitor your sender reputation using blacklist and RBL tools.
• Avoid sending large attachments or overly promotional messages.

Benefits of Email Deliverability Testing

• Ensures your emails reach inboxes, not spam folders.
• Improves sender reputation and trust with ISPs.
• Increases open and engagement rates.
• Reduces bounce rates and prevents domain blacklisting.
• Strengthens overall email marketing performance.

Example Email Authentication Setup

example.com TXT "v=spf1 include:_spf.google.com ~all"

default._domainkey.example.com TXT "v=DKIM1; k=rsa; p=MIGfMA0G..."

_dmarc.example.com TXT "v=DMARC1; p=quarantine; rua=mailto:dmarc@example.com"

This configuration ensures full email authentication, reduces spoofing risks, and improves inbox placement.
