The what, where, why, and how of email deliverability
Everything you need to know about spam and email deliverability.
How do I check if my emails are marked as spam?
The most reliable way to check if your emails are going being marked as spam is to use a third-party tool to check your spam or sender score. If you don’t have access to a third-party tool, monitoring key email engagement metrics like open and click-through rate over time can help you identify when your emails are being delivered to the spam folder. If you see a sudden decrease in email engagement metrics, that could be a sign that emails are not being successfully delivered to the inbox.
What metrics should I track to monitor email deliverability?
Monitoring email deliverability is crucial for email marketers to ensure their messages are reaching subscribers’ inboxes. Here are some key metrics you should track to monitor email deliverability effectively:
- Delivery rate indicates the percentage of emails that were successfully delivered to the recipients’ inboxes.
- Bounce rate measures the percentage of emails that were not delivered successfully due to various reasons including invalid email addresses, full mailboxes, or serve issues. There are two types of bounces: hard bounces (permanent delivery failures) and soft bounces (temporary delivery failures).
- Click-through rate (CTR) indicates the percentage of recipients who clicked on your email out of the total number of emails delivered successfully. While CTR rate doesn’t directly measure deliverability, it reflects email engagement which can impact email deliverability.
- Spam complaint rate measures the percentage of recipients who marked your emails as spam or junk. High spam complaint rates can negatively impact your sender reputation and email deliverability.
By tracking these key metrics analyzing trends over time, you can identify areas for improvement and enhance your overall email deliverability.
How can I avoid spam traps?
Avoiding spam traps is crucial for maintaining a good sender reputation and ensuring high email deliverability rates. Here are some ways to help you avoid spam traps:
- Use permission-based lists: Only send to subscribers who have explicitly opted in to receive communications from you. Do not use purchased or rented lists, as they often contain outdated or invalid email addresses that can include spam traps.
- Maintain list hygiene: Implement a re-engagement program to regularly clean your email list to remove inactive or disengaged subscribers.
- Verify email addresses: Implement a double opt-in process (DOI) where subscribers must confirm their email addresses after subscribing to your emails. This helps ensure that email addresses are valid and owned by real individuals, reducing the likelihood of hitting spam traps.
- Follow email best practices: Adhere to email best practices like not using deceptive subject lines, and including a visible unsubscribe link in your emails. Comply with anti-spam laws such as the CAN-SPAM Act and GDPR to maintain trust and credibility with subscribers and inbox providers (ISPs).
How do I get off a blocklist?
Getting off a blocklist can be a challenging but necessary process to restore your email deliverability and sender reputation. Here are some steps you can take to get off a blocklist:
- Identify the blocklist: Determine which blocklist you have been listed on using online tools like Litmus Spam Filter testing.
- Investigate the reason for listing: Once you’ve identified the blocklist, investigate the reason why your IP address or domain was listed. Common reasons for listing include a high volume of spam complaints, poor email authentication practices, or compromised email accounts.
- Request removal: Most blocklists provide a process for requesting removal. Visit the website of the blocklist that listed your IP address or domain and follow their instructions for removal. You may need to provide information such as your IP address, domain name, and details about the actions you’ve taken to resolve the issue.
- Monitor your reputation: After requesting removal, monitor your email deliverability and sender reputation closely. Keep an eye on bounce rates, spam complaints, and other deliverability metrics to ensure that your emails are reaching recipients’ inboxes.
- Implement email authentication: Implement email authentication protocols such as SPF, DKIM, and DMARC to protect your sender reputation. Proper authentication helps verify the legitimacy of your emails and reduces the risk of being listed on blocklists.
- Be patient: Getting off a blocklist may take time, and it may require multiple attempts to request removal. Be patient and persistent in your efforts to resolve the issue and restore your sender reputation.
By following these steps and addressing the underlying issues that led to the listing, you can improve your chances of getting off a blocklist and restoring your email deliverability and sender reputation.
