Email Best Practices: Avoiding Spam Filters and Enhancing Communication


At EJB Technology Support, LLC, we value our customers and understand that effective email communication is vital in our ongoing partnership. Sending emails that get caught in spam filters can hinder your messages from reaching their intended recipients. To ensure that your emails are delivered successfully and efficiently, we’ve compiled a guide with best practices and resolutions for common spam filter issues. Let’s explore how you can optimize your email communications.

  1. Maintain a Consistent Sending Identity:

To establish trust with email providers and recipients, use a consistent “From” address and domain. Frequent changes to your sending identity can trigger spam filters.

  1. Use a Recognizable “From” Name:

Ensure that your recipients can easily recognize you by using a familiar and relevant “From” name. This helps build trust and credibility.

  1. Craft Relevant and Engaging Subject Lines:

Avoid misleading or sensational subject lines. Instead, create concise, relevant subject lines that accurately reflect the email’s content.

  1. Minimize HTML and CSS Styling:

Excessive HTML and CSS styling in your emails can trigger spam filters. Keep your email templates clean and avoid flashy design elements.

  1. Avoid Overuse of Images:

Emails with too many images and little text can be flagged as spam. Balance your content with both text and images and use descriptive alt text for images.

  1. Authenticate Your Emails:

Implement authentication methods like SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to verify your email’s authenticity, reducing the likelihood of being marked as spam.

  1. Check for Blacklist Status:

Regularly monitor the status of your sending IP address and domain on email blacklists. Being on a blacklist can significantly impact email deliverability.

  1. Use a Reputable Email Service Provider:

Consider using a reputable email service provider (ESP) that specializes in email deliverability. ESPs have the infrastructure and expertise to manage deliverability effectively.

  1. Avoid Using URL Shorteners:

While URL shorteners are convenient, they can raise suspicions. Use full, descriptive URLs whenever possible to enhance transparency.

  1. Test Your Emails:


Before sending important emails, run them through spam filter testing tools to identify potential issues. This proactive approach can help you fine-tune your messages before sending.

  1. Encourage Engagement:


Actively encourage your recipients to engage with your emails by clicking links, replying, or marking your emails as “Not Spam.” Engaged subscribers are less likely to have your emails marked as spam.

  1. Monitor Your Email Analytics:


Regularly review email analytics to track delivery rates, open rates, and click-through rates. Identifying trends can help you fine-tune your email strategy.

  1. Respect Unsubscribe Requests:


Honor unsubscribe requests promptly. Failing to do so not only harms your sender reputation but can also lead to regulatory issues.
