5 Steps to Avoid Spam Emails in Magento: An Ultimate Guide

Wondering how to avoid spam emails in Magento 2?

Emails remain one of the most powerful tools to update customers about their orders, shipping, and store promotions. But if your Magento emails constantly land in the spam folder, they lose their value and hurt customer trust.

In this guide, we’ll break down the main reasons Magento emails are flagged as spam and share practical steps to fix them. With the right Magento 2 SMTP settings and smart configurations, you can boost deliverability, keep your messages out of spam, and ensure they reach the inbox every time.

5 Common Reasons Magento 2 Emails End Up in Spam

Email providers use spam filters to block suspicious messages before they reach the inbox. These filters analyze different factors, such as:

• Content filters: check for spammy words, broken HTML, or excessive links.
• Blacklist filters: block emails sent from domains or IPs with poor reputation.
• Header filters: detect inconsistencies in email headers or SMTP transactions.
• Language/country & rule-based filters: flag unusual languages or specific messages that match predefined “banned” rules.
• Machine learning filters: learn from large datasets to predict and block new spam patterns.
• Source filters: check the authentication protocols (for example: SPF, DKIM, and DMARC) to identify frequently-changed domains and email addresses by spammers.

So why do Magento 2 emails often get into spam inbox? Here are top 5 reasons why:

• Misconfigured SMTP settings: Using default PHP mail or entering incorrect SMTP credentials can make your emails look untrustworthy. Correct Magento 2 SMTP settings ensure proper authentication and smoother delivery.
• Missing SPF, DKIM, or DMARC records: Without these DNS records, your domain can’t verify itself to email providers. This often leads to emails being marked as spam or rejected entirely.
• Poor sender reputation (IP/domain): If your server IP or domain has been blacklisted or flagged for suspicious activity, inbox providers will automatically downgrade or block your messages.
• High sending volume without warm-up: Sending large numbers of emails from a new IP or domain without gradually increasing volume can trigger spam filters. Warming up helps build trust.
• Unoptimized email content: Spammy phrases, excessive links, broken HTML, or missing headers can activate content filters. Clean, well-structured templates improve inbox placement.

Steps to Avoid Spam Emails in Magento 2

Step 1: Maintain a Clean Domain Reputation

First and foremost, building a clean domain reputation is essential for convincing spam filters and ESPs of your authenticity, which in turn improves email delivery. Here’s how to establish a good domain reputation:

Comply with the CAN-SPAM Act

When sending emails through Magento, you must adhere to the rules and regulations set by the CAN-SPAM Act. This law ensures that email-sending activities remain ethical. To ensure your emails reach recipients’ inboxes, remember to:

• Avoid false or misleading information.
• Clearly label the message as an ad.
• Include the sender’s location.
• Respect recipients’ requests to opt out of future emails.
• Monitor how others represent your brand.

Use an Established Domain

If you’re using a new domain, opting for an established one can be beneficial. A domain with stability and longevity can enhance your reputation and increase the chances of your emails landing in the primary inbox.

Let’s take an example of how to set up a domain correctly:

Limit Emails Per Domain

The amount of emails you can send is limited by email service providers. Make sure your email campaigns adhere to these restrictions, as going over them could damage the reputation of your site.

Use Exclusive Domains for Specific Activities

Creating separate domains for different functions can help personalize your activities, streamline your workflow, and manage queries effectively, all while building a solid reputation over time. For example, having distinct domains for customer service, general information, and partnerships can prevent confusion and improve email domain management.

Step 2: Configure Servers and IPs

Use a Dedicated IP Address

Ensure you use a dedicated IP address instead of a shared one. Shared IPs can expose your email reputation to the risks of spammers using the same IP. A dedicated IP helps protect your email deliverability and optimizes your Magento conversion rates by avoiding the risk of being blocked due to others’ actions. Using tools like GlockApps allows you to gain full visibility into your IP and domain reputation and email deliverability across global providers.

Configure Email Authentication: SPF, DKIM, and DMARC

• SPF (Sender Policy Framework): This layer verifies that emails from your domain are sent from your IP address, preventing spoofing.
• DKIM (DomainKeys Identified Mail): This involves a private key, public key, and signature in the domain’s DNS record to verify the sender’s authenticity.
• DMARC (Domain-based Message Authentication, Reporting & Conformance): This protocol often implemented by a top DMARC provider, executed with SPF and DMARC records, ensures emails are delivered to the primary inbox. SPF checks the sending IP’s authority to send emails for the domain, while DKIM uses cryptographic signatures to verify the message content’s integrity.

Utilize an SMTP Server

You can send emails on Magento using the Simple Mail Transfer Protocol (SMTP) by using a particular third-party SMTP service. With services like Gmail, Amazon, Microsoft, or any other mail server account, this makes it simple to send emails from one server to another.

With your server configured, you can move to the next step.

Step 3: Build Effective Email Structures for Magento Emails

Below is the recommended Email Structure to Avoid Spam in Magento.

Include a Plain Text Part

Magento typically sends only the HTML part of emails, which can increase the spam score. To improve compatibility and accessibility, manually create text parts for each email template or automatically generate them from the HTML version.

Adjust Quote-Printable Line Length

The standard quote-printable line length should be up to 998 characters to comply with the RDC 2822 specification and enhance readability. Magento’s default line length for print-quotable content is 200 characters, but you can adjust this value as needed.

Embed Images

Emails without images are more likely to be classified as spam. Enhance your email security by including at least one image in your message. However, avoid using images from external sources.

Use Valid HTML Structure

Work with an experienced HTML developer to ensure your email body has a well-structured HTML layout. Stick to simple HTML and tables, avoiding complex CSS3.

These are the main guidelines for formatting emails. Next, let’s move on to how to optimize your email content to avoid spam in Magento.

Step 4: Optimize Email Content for Magento

Valuable Text

Make sure the content in your emails is something your readers would actually find interesting. First, divide up your audience into several groups, then target each group with communications that are pertinent to them.

Avoid Spam Trigger Words

Terms like “discount,” “free,” and “buy now” frequently cause spam. They may draw attention, but they also make it more likely that your emails will be regarded as spam. Instead, take a customized strategy to ensure that your information is understandable and relatable.

Avoid Link Shorteners

While shortened links look cleaner, they can undermine trust and increase the chances of your emails being marked as spam. Use full, descriptive URLs to maintain transparency and authenticity with your recipients.

Use High-Resolution and Relevant Images

Include images in your emails to add value, but avoid using just one image or too many images. A single image can be seen as spam, and too many can dilute your message. Add a moderate number of high-resolution, relevant images to enhance your content.

Step 5: Test Email Messages

Use Third-Party Services

Before sending emails, it’s crucial to test them. Third-party services can help you evaluate the email’s spam score and provide previews on various platforms and devices. They also offer suggestions for improving your email’s HTML coding.

Review With Your Team

After creating an email in Magento, send it to your staff and teammates for feedback. Use their input to refine and enhance the quality and effectiveness of your email content.

Ensure Mobile Compatibility

Magento’s flexible design is crucial for reaching a wider audience, especially considering the significance of smartphones. Make sure your emails work well on mobile devices by testing them there.

Step 6: Warm Up Your Sending IP/Domain

If you’re starting fresh with a new domain or IP, gradually increase your email volume instead of sending bulk right away. This step helps build trust with email providers and avoids sudden spam flags.

Common Pitfalls & Limitations

Even when you’ve configured email settings correctly, there are a few common pitfalls that Magento store owners often face:

• Relying only on default SMTP: Since Magento 2.4.6, a built-in SMTP option is available, but it’s very limited. Without advanced features like authentication testing, error logs, or email history, problems can easily go unnoticed.
• Incomplete DNS records: Forgetting to add SPF, DKIM, or DMARC records means your domain can’t verify itself, so emails may still be flagged as spam or rejected.
• Shared hosting restrictions: Many hosting providers limit outgoing emails or assign you a shared IP. If that IP is already on a blacklist, your messages are more likely to be filtered.
• Sudden spikes in email volume: Sending thousands of messages at once (like newsletters or promotions) from a new IP can damage your sender reputation. Even transactional emails like order confirmations may be affected.
• Content issues: Overuse of spammy words, broken HTML, or missing headers can trigger filters even if SMTP is configured correctly.
