Why Do Mailchimp Emails Keep Ending up in Spam? In today’s digital age, email marketing plays a crucial role in reaching out to customers and promoting businesses. However, many email marketers face a common challenge: their emails often end up in the recipients’ spam folders instead of reaching the inbox. One popular email marketing platform, Mailchimp, has also encountered this issue. In this article, we will explore why Mailchimp emails sometimes go to spam and provide practical solutions to improve email deliverability.

Mailchimp is a popular email marketing platform that helps businesses send email newsletters and promotions to their subscribers. However, sometimes Mailchimp emails go to spam. This can be frustrating for businesses, as it means that their emails are not reaching their intended audience.

Understanding Email Deliverability

Email deliverability refers to the ability of an email to successfully land in the recipient’s inbox rather than being marked as spam or blocked by filters. It depends on various factors, including the reputation of the sender, the content of the email, and the technical setup of the sending infrastructure.

There are a number of reasons why Mailchimp emails might go to spam. Some of the most common reasons include:

  • The content of the email is spammy. This could include using spammy subject lines, sending too many emails too often, or using deceptive practices such as phishing or malware.
  • The email address is not on the recipient’s approved list. This means that the recipient has not explicitly opted in to receive emails from the sender.
  • The email is not properly formatted. This could include using all caps, using too many exclamation points, or having a poor-quality sender name or email address.
  • The email is sent from a shared IP address. This means that the email is being sent from an IP address that is also used by other senders, some of whom may be sending spam.

If you are sending Mailchimp emails and they are going to spam, there are a number of things you can do to fix the problem. Here are some tips:

  • Make sure the content of your emails is not spammy. Use clear and concise subject lines, send emails at a reasonable frequency, and avoid deceptive practices.
  • Make sure the email address is on the recipient’s approved list. This can be done by using a double opt-in process, which means that the recipient must confirm their email address before they can start receiving emails.
  • Properly format your emails. Use a clear and professional sender name and email address, and avoid using all caps or too many exclamation points.
  • Send your emails from a dedicated IP address. This will help to ensure that your emails are not marked as spam by spam filters.

By following these tips, you can help to ensure that your Mailchimp emails do not go to spam. This will help you to reach your intended audience and improve your email marketing results.

Best Practices to Improve Mailchimp Email Deliverability

Build a High-Quality Email List

Focus on growing an engaged and permission-based email list. Implement double opt-in to confirm subscribers and avoid purchasing email lists. Regularly engage with your subscribers to maintain their interest and reduce the chances of them marking your emails as spam.

Maintain a Good Sender Reputation

Monitor your sender reputation using tools like Sender Score or similar services. Implement email feedback loops to receive notifications when subscribers mark your emails as spam. Respond promptly to unsubscribe requests and handle spam complaints effectively.

Optimize Email Content and Formatting

Create compelling and relevant content that resonates with your audience. Personalize your emails and segment your list to deliver targeted messages. Avoid using excessive images or attachments and balance text-to-image ratios. Test your emails across different email clients and devices to ensure compatibility.

Implement Email Authentication

Properly authenticate your domain to establish trust with ISPs and email providers. Set up SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) records. These measures help prevent email spoofing and improve deliverability.

Monitor and Test Email Deliverability

Regularly monitor your email deliverability metrics within Mailchimp. Pay attention to open rates, click-through rates, bounce rates, and spam complaints. Conduct A/B testing to optimize your email campaigns and identify areas for improvement.

Additional Tips to Avoid Mailchimp Emails Going to Spam

In addition to the tips above, there are a few other things you can do to avoid Mailchimp emails going to spam:

  • Use a good email marketing service provider. Mailchimp is a great email marketing platform, but there are other good options available. When choosing an email marketing service provider, look for one that has a good reputation for deliverability.
  • Segment your email list. This means dividing your email list into smaller groups based on interests, demographics, or other factors. This will help you to send more relevant emails to your subscribers, which will reduce the chances of your emails being marked as spam.
  • Personalize your emails. This means using the recipient’s name in the email and addressing them directly. Personalizing your emails will make them more likely to be opened and read, which will also reduce the chances of them being marked as spam.
  • Use a good email deliverability service. There are a number of email deliverability services available that can help you to improve the deliverability of your emails. These services can help you to identify and fix spammy content in your emails, and they can also help you to track the performance of your email campaigns.

By following these tips, you can help to ensure that your Mailchimp emails do not go to spam. This will help you to reach your intended audience and improve your email marketing results.


Ensuring that your Mailchimp emails reach the intended recipients’ inboxes is crucial for the success of your email marketing campaigns. By understanding the factors affecting email deliverability and implementing best practices, you can improve your Mailchimp email deliverability. Remember to maintain a high-quality email list, focus on sender reputation, optimize email content and formatting, implement proper authentication, and continuously monitor and test your email deliverability.
