 Why Are Your Mailchimp Emails Going to Spam Folders?


Email marketing is an effective method that businesses can use in the modern digital era to connect with customers, establish rapport, and increase traffic. Mailchimp has become the leading platform because of its extensive capabilities and easy-to-use design. Nonetheless, email marketers frequently struggle with the constant possibility that their well-prepared messages could land in recipients’ spam. The consequences of this are profound, potentially resulting in reduced open rates, diminished brand credibility, and missed opportunities for meaningful communication. This challenge underscores the critical importance of understanding and implementing strategies to prevent Mailchimp campaigns from going to spam.

As businesses invest time and resources into crafting compelling content, it becomes imperative to ensure that these messages reach the intended audience directly into their primary inboxes. This is where an email warmup tool such as InboxIgniter becomes an invaluable asset in an email marketer’s toolkit. Even the most well-crafted email marketing campaign can become a disaster if your carefully designed emails end up in the user’s junk folder. Email automation platforms like Mailchimp have gained significant popularity by providing effective solutions to prevent this. However, emails can end up going to the spam folders if not handled carefully. Compliance with the company’s Terms of Use and good intentions alone may not be sufficient. Mailchimp, valuing its reputation, has various tricks and challenges to navigate to ensure your email outreach provides the desired results.

Mailchimp Anti-Spam Policies and Spam Filters

As a top email marketing platform, Mailchimp is dedicated to protecting the ecosystem’s integrity by using advanced spam filters and strict anti-spam rules. These guidelines are intended to guarantee that users follow the law, industry best practices, and ethical principles. Following these anti-spam policies strictly can help Mailchimp users achieve their email marketing goals while adhering to laws such as the CAN-SPAM Act and GDPR. These policies cover legal compliance, email list quality, content guidelines, and the use of individual servers. Mailchimp’s Omnivore protection system detects and addresses potential spam threats by checking new addresses for spam traps, hard bounces, and abuse complaints. 

It’s essential to note that recipient servers also play a crucial role in email delivery, and Mailchimp cannot control the recipient server’s anti-spam protocols. Mailchimp’s stringent anti-spam policies encompass guidelines on obtaining explicit permission from contacts, avoiding the use of purchased or rented email lists and refraining from engaging in deceptive practices. The platform analyzes the content, structure, and sender reputation of each email to determine its likelihood of being classified as spam. This multi-faceted approach helps protect both parties, ensuring that legitimate messages reach inboxes while mitigating the impact of unsolicited or potentially harmful content. It’s essential for users to familiarize themselves with Mailchimp’s anti-spam policies to guarantee compliance and optimize their campaigns for successful delivery.

Additionally, understanding the spam triggers empowers marketers to craft content that not only aligns with Mailchimp’s guidelines but also resonates positively with the algorithms governing email deliverability. By proactively aligning with its anti-spam measures, Mailchimp account users can build a trustworthy reputation, enhance the effectiveness of their email marketing endeavors, and foster a positive relationship with their audience. Mailchimp’s focus on upholding a dependable and secure email environment is shown in the continued revision of the policies, giving users peace of mind that their messages will be delivered to the intended recipients.

13 Proven Tips to Get Your Emails to the Inbox Using Mailchimp

Set up Custom Email Domain Authentication

To enhance the credibility of your marketing emails and reduce the likelihood of them being marked as spam, set up custom email domain authentication. This involves configuring your domain’s settings to authorize email services like Mailchimp to send messages on your behalf. By doing so, you establish trust with email providers and increase the deliverability of your messages.

Ask Your Recipients to Mark Your Emails as Not Spam

Encourage your email recipients to mark your emails as “Not Spam” if they find them in their spam folder. This action signals to their email provider that your content is wanted and helps improve the deliverability rates of future emails. Building this positive engagement with your audience can also improve inbox placement over time.

Make Sure You Get Explicit Permission from Your Contacts

Always obtain explicit permission from your contacts before beginning with your Mailchimp campaigns. This not only complies with privacy regulations but also ensures that your messages are welcomed by your subscribers. Building a permission-based list establishes a foundation for a positive sender-receiver relationship.

Ask Contacts to Add You to Their Safe Sender List

Encourage your contacts to add your email address to their safe list. This proactive step by recipients can prevent your emails from ending up in spam folders, providing a direct route to their inbox.

Make Sure Email Content is Compliant with Mailchimp Terms of Use

Adhere to Mailchimp’s Terms of Use when creating email content. This ensures that your campaigns comply with industry standards and legal requirements, reducing the risk that your messages get flagged as spam or violate regulations.

Use Merge Tags to Personalize the "To" Field

Utilize merge tags to personalize the “To” field of your emails. Adding a personal touch to your messages can enhance engagement and make your emails more appealing to recipients.

Add an Unsubscribe Link to Your Campaigns and Permission Reminder

Include an unsubscribe link in your emails and a permission reminder to provide recipients with an easy way to opt-out if they wish. This not only complies with regulations but also demonstrates transparency and respect for your audience’s preferences.

Use Mailchimp's Campaign Builder to Design a Clean Email Campaign

Leverage Mailchimp’s Campaign Builder to design visually appealing and clean email campaigns. A well-structured layout and design contribute to a positive user experience and can improve the effectiveness of your communication.

Use Descriptive Text Links and Try Disabling Link Tracking

Opt for descriptive text links in your emails and experiment with disabling link tracking. This can sometimes help avoid spam filters, as some email providers may interpret extensive link tracking as suspicious behavior.

Ensure You Use a Basic Text Editor for HTML Emails

When creating HTML emails, use a basic text editor to prevent formatting issues and ensure compatibility across different email clients. This helps maintain the integrity of your email design and improves the chances of successful delivery.

Test and Preview Your Email Thoroughly Before You Send

Before sending emails, thoroughly test and preview them. Check for formatting issues, and broken links, and ensure that your content displays correctly across various devices and email clients. Avoid using spammy content in the subject line or anywhere in the email.

Ensure Your Email Has No Affiliate Content

Avoid including affiliate content in your emails, as this can trigger spam filters. Maintain a focus on providing valuable and relevant information to your audience rather than promoting external affiliate links.

Make Sure Your Contact List Has None of the Prohibited Role-Based Addresses

Regularly review your contact list to ensure it does not contain prohibited role-based addresses. These addresses are often associated with generic roles rather than individual recipients and may result in deliverability issues. Keeping your list clean and targeted improves the effectiveness of your email marketing efforts.


While some emails may end up in the spam folder, viewing it as an opportunity to identify and address underlying issues can strengthen customer loyalty. Building a reputable domain starts with a holistic approach to email deliverability. Mastering the art of preventing Mailchimp emails from landing in spam folders is a pivotal step in optimizing your email marketing strategy. By prioritizing custom email domain authentication, you establish a foundation of trust with email providers, signaling that your messages are legitimate and eagerly anticipated by your audience. Encouraging recipients to mark your emails as “Not Spam” and adding you to their safe sender list fosters a proactive relationship, further solidifying your position as a trusted sender. Explicit permission from your contacts is not merely a legal requirement but a strategic choice to build a responsive and engaged audience.

Complying with Mailchimp’s Terms of Use ensures that your content aligns with industry standards, reducing the risk of being flagged as spam. The use of merge tags for personalization adds a human touch, resonating with your audience on a more individual level. Including an unsubscribe link and permission reminder demonstrates transparency and respect for your audience’s preferences, fostering a sense of control for recipients. Leveraging Mailchimp’s Campaign Builder and employing clean, visually appealing designs contribute to a positive user experience, enhancing the likelihood of your messages being well-received. Testing and previewing emails across devices and platforms become imperative in a diverse digital landscape. These strategies can reduce the likelihood that your emails land in the spam folder.

Avoiding affiliate content and ensuring your contact list remains free of prohibited role-based addresses are crucial steps in maintaining a clean and deliverable email ecosystem. Success in email marketing is an ongoing process of adaptation and optimization.
