Email marketing is a highly favored advertising channel due to its ability to get your content directly to your target. Yet, this benefit only occurs if your emails are actually being seen. This is known as deliverability: the ability your emails have to effectively reach their intended audience. Many people new to email marketing unknowingly trigger spam filters, drastically impacting the effectiveness of their campaigns. Luckily, this is an easy fix and our guide below will help you get your emails into customers inboxes, and not spam folders.t. Ut elit tellus, luctus nec ullamcorper mattis, pulvinar dapibus leo.
What Are Spam Filters?
Spam filters are software that come preinstalled with popular inboxes like Gmail and Outlook. These algorithms scan every incoming email for potentially dangerous or unnecessary information and decide if it should go into a user’s main inbox or their spam folder. Factors influencing this decision include:
- Sender reputation (Are you a trusted source?)
- Email content (Does it sound like spam?)
- Engagement (Do recipients open, click, or delete your emails?)
- Authentication and compliance (Is your domain verified? Do you follow the rules?)
Many people conflate being sent to spam as a random event, but there is a method to the process. Avoiding factors that cause your marketing to be sent there is the key to enhancing your deliverability.
How to Avoid Spam Filters
Taking the right precautions can significantly reduce your chances of being flagged as spam. Below are essential strategies to help ensure your emails land directly into your customer’s inbox.
Use a Reputable Email Marketing Platform
Never send marketing emails directly from Gmail, Outlook, or your personal inbox. Not only does this look unprofessional, it increases the risk of getting caught in spam filters.
Instead, use a trusted email marketing platform like Klaviyo, Mailchimp, Brevo, or Constant Contact. These platforms have built-in tools to manage compliance, improve deliverability, and guide you through best practices. At Rise, we highly recommend Klaviyo for its powerful automation and advanced segmentation features.
Never Buy an Email List
Purchasing an email list seems like a great way to get immediate access to more inboxes, however it often does more harm than good. The issue here is that there is no consent from the person you are sending your email to. Without clear consent, your emails are more likely than not going to be flagged as spam, and repeated offenses can cause a negative reputation with email service providers. Instead, build your list organically. Focus on attracting people who genuinely want to engage with your brand.
Authenticate Your Domain
If you’ve never heard of SPF, DKIM, or DMARC, don’t worry, but know they’re crucial for deliverability. These email authentication methods tell inbox providers that you are a legitimate and credible sender. Luckily, most modern email platforms (like the ones mentioned above) walk you through the setup. It’s worth taking the time to get this right. Without authentication, your emails are more likely to be flagged as suspicious, especially by strict providers like Gmail and Outlook.
Write Like a Human, Not a Robot
Spam filters are trained to detect unnatural or overly promotional language. Avoid trigger words and tactics like:
- “FREE!!!” or “100% GUARANTEED”
- Excessive punctuation
- All caps subject lines
- Overusing emojis
Instead, write clear, honest, and helpful content. Your subject lines should feel personal and genuine, rather than aggressive sales tactics.
Balance Text and Images
Emails that only contain images or text can raise red flags. A well-balanced layout is not just more visually appealing, it’s more likely to be sent to a user’s inbox. The best method is to mix short blocks of text with relevant images, use alt text on every image, and include a plain-text version of your email (most platforms handle this automatically).
Include Clear Unsubscribe Option and Contact Info
Including a visible unsubscribe link and contact details isn’t optional, it’s the law. Under regulations like CAN-SPAM and GDPR, every marketing/promotional email must give recipients a clear way to opt out. Beyond legal compliance, these details help build trust with your mailing list. Make sure your email footer includes your business name, physical address, and a working unsubscribe link. This not only reassures readers, but also shows spam filters that you are following their guidelines and adhering to industry standards.
Monitor Engagement and Clean Your List
Low engagement is a signal to inbox providers that your emails aren’t wanted. If people consistently ignore or delete your messages, filters take notice and start rerouting future emails to spam. To avoid this, track open and click rates, regularly remove inactive or bounced addresses, and use re-engagement campaigns to win back inactive subscribers. Many platforms allow you to automate list cleaning or segment based on engagement. Use these tools regularly to keep up with your metrics.
Being Marked As Spam Is a Death Sentence
To put it bluntly, if an inbox provider like Gmail starts flagging your emails as spam, recovery is almost impossible. Reversing this process is incredibly difficult and in many cases, your emails will never reach Gmail users again. That means missed revenue, lost customers, and wasted effort.
