Improving Email Deliverability: Tips for Australian Senders

Understanding Sender Reputation

Your sender reputation is like your credit score for email. Internet Service Providers (ISPs) use it to assess the trustworthiness of your emails and decide whether to deliver them to the inbox, spam folder, or block them altogether. A good sender reputation is crucial for consistent email deliverability.

Several factors contribute to your sender reputation, including:

Email volume: Sending large volumes of email suddenly can raise red flags.
Spam complaints: High complaint rates negatively impact your reputation.
Bounce rate: A high bounce rate indicates poor list hygiene.
Engagement: Positive engagement (opens, clicks, replies) improves your reputation.
Blacklisting: Being listed on a blacklist can severely damage your deliverability.

Common Mistakes:

Ignoring sender reputation metrics.
Sending unsolicited emails (spam).
Using shared hosting for high-volume sending.

Actionable Advice:

Regularly monitor your sender reputation using tools provided by email service providers (ESPs) or third-party services.
Warm up your IP address gradually when starting a new email programme.
Focus on providing valuable content that recipients want to receive.

Implementing Email Authentication (SPF, DKIM, DMARC)

Email authentication protocols help ISPs verify that the emails you send are genuinely from you and haven't been forged by spammers. Implementing SPF, DKIM, and DMARC is essential for improving your sender reputation and deliverability.

SPF (Sender Policy Framework): Specifies which mail servers are authorised to send emails on behalf of your domain. This prevents spammers from using your domain to send fraudulent emails.
DKIM (DomainKeys Identified Mail): Adds a digital signature to your emails, allowing recipient servers to verify that the email hasn't been tampered with during transit.
DMARC (Domain-based Message Authentication, Reporting & Conformance): Builds on SPF and DKIM by providing instructions to recipient servers on how to handle emails that fail authentication checks. It also allows you to receive reports on authentication results, helping you identify and address potential issues.

Common Mistakes:

Not implementing SPF, DKIM, and DMARC.
Incorrectly configuring authentication records.
Failing to monitor DMARC reports.

Actionable Advice:

Generate SPF, DKIM, and DMARC records for your domain and publish them in your DNS settings. Your ESP should provide instructions on how to do this.
Regularly review your DMARC reports to identify and address any authentication failures. This helps prevent spoofing and phishing attacks that could damage your sender reputation.
Use a DMARC record generator tool to ensure your record is correctly formatted. Incorrectly formatted records can lead to authentication failures.

Maintaining a Clean Mailing List

A clean mailing list is crucial for maintaining a good sender reputation and improving email deliverability. Sending emails to invalid or inactive email addresses can lead to high bounce rates and spam complaints, negatively impacting your reputation.

Key Practices for List Hygiene:

Double Opt-in: Require subscribers to confirm their email address before adding them to your mailing list. This ensures that you only send emails to people who genuinely want to receive them.
Regularly Remove Inactive Subscribers: Identify and remove subscribers who haven't opened or clicked on your emails in a long time. These subscribers are unlikely to engage with your content and can negatively impact your deliverability.
Handle Bounces Promptly: Immediately remove bounced email addresses from your mailing list. Repeatedly sending emails to invalid addresses can damage your sender reputation.
Provide an Easy Unsubscribe Option: Make it easy for subscribers to unsubscribe from your mailing list. This reduces the likelihood of them marking your emails as spam.

Common Mistakes:

Purchasing email lists.
Not using double opt-in.
Ignoring bounce rates.
Making it difficult to unsubscribe.

Actionable Advice:

Implement a double opt-in process for all new subscribers.
Use an email list cleaning service to identify and remove invalid or inactive email addresses.
Segment your mailing list based on engagement and send targeted emails to different segments.
Actively manage unsubscribe requests and ensure that subscribers are promptly removed from your mailing list.

Avoiding Spam Trigger Words

Spam filters are designed to identify and block unwanted emails. Using certain words or phrases in your email subject lines or body can trigger these filters and prevent your emails from reaching the inbox. While the exact list of trigger words varies, some common examples include "free," "guarantee," "urgent," and excessive use of exclamation marks or capital letters.

Common Mistakes:

Using excessive exclamation marks or capital letters.
Making unrealistic promises.
Using spam trigger words in subject lines.

Actionable Advice:

Avoid using spam trigger words in your email subject lines and body.
Write clear, concise, and informative content.
Use a spam checker tool to identify potential issues before sending your emails.
Test your emails with different spam filters to see how they are classified.

Monitoring Deliverability Metrics

Monitoring your email deliverability metrics is essential for identifying and addressing potential issues. Key metrics to track include:

Bounce Rate: The percentage of emails that fail to be delivered.
Complaint Rate: The percentage of recipients who mark your emails as spam.
Open Rate: The percentage of recipients who open your emails.
Click-Through Rate (CTR): The percentage of recipients who click on a link in your email.
Unsubscribe Rate: The percentage of recipients who unsubscribe from your mailing list.

Common Mistakes:

Not tracking deliverability metrics.
Ignoring warning signs.
Not acting on deliverability issues.

Actionable Advice:

Regularly monitor your deliverability metrics using your ESP's reporting tools.
Set up alerts to notify you of any significant changes in your metrics.
Investigate and address any issues that are impacting your deliverability.
Compare your metrics to industry benchmarks to see how you are performing.

Troubleshooting Delivery Issues

If you experience email delivery issues, it's important to troubleshoot the problem to identify the cause and implement a solution. Common causes of delivery issues include:

Blacklisting: Your IP address or domain may be listed on a blacklist.
Authentication Issues: Your SPF, DKIM, or DMARC records may be incorrectly configured.
Content Issues: Your emails may contain spam trigger words or other content that triggers spam filters.
List Hygiene Issues: Your mailing list may contain invalid or inactive email addresses.

Common Mistakes:

Ignoring delivery issues.
Not investigating the cause of the problem.
Making assumptions about the cause of the problem.

Actionable Advice:

Check your IP address and domain against common blacklists using online tools.
Verify that your SPF, DKIM, and DMARC records are correctly configured.
Review your email content for spam trigger words and other potential issues.
Clean your mailing list to remove invalid or inactive email addresses.
Contact your ESP's support team for assistance.
