After crafting what you thought to be the best email, it is delivered not to intended mailboxes, but instead, to the spam folder.

Wheeeew! Isn’t it Plastered! Learning the root problem is the first step to improve inbox placement. 

Below you will find an explanation in most case of the top 10 reasons why your emails might be getting marked as spam and some tips on how to avoid spam filters effectively.

1. You’re Using Too Many Email Spam Triggers

Spam filters work by weeding out emails with common errors such as the overuse of caps. Hence, the presence of too many exclamation points and misleading subject lines are examples of the red flags they look for. Take out words such as “FREE,” “GUARANTEED,” and “CLICK HERE” from your vocabulary, as these are classic spam words to avoid. Instead, use natural, conversational language to improve inbox placement as well as user engagement.

2. Your Sender Reputation is Suffering

The sender reputation that you have got is the main contributing factor as to whether your emails make it to the inbox or not. There are times when your previous emails might have raised some spam complaints and for that reason, your future emails could be flagged automatically. Sending relevant and valuable content to engaged recipients always will definitely preserve your nice sender reputation.

3. Your Recipients Marked You as Spam

Email providers have the right to cancel your account if many users block your emails as spam. Spam complaints occurs, usually, when you make advances to users without their consent or you use a deceptive title. Make sure that your emails are rather accepted than annoyed by your use of clear, permission-based marketing tactics.

4. You’re Not Following CAN-SPAM Compliance

One of the laws that is in power now, the CAN-SPAM compliance, means that marketers should include in their emails a way to opt out. The wrong practice of not including the unsubscribe link and misleading the users about sender information can result in great fines and low sender reputation.

5. You Haven’t Set Up Proper Email Authentication Protocols

Email service providers need email authentication protocols including SPF, DKIM, and DMARC to be able to check if you are the real author of that email. So if these protocols are not configured, your emails could be either rejected or classified as spam. Work with your email service provider to authenticate your domain.

6.Email Content Structured Very Badly 

A badly-structured email with too many hyperlinks, oversized images, or attachments may also raise spam filters. Remember your email content best practices, making sure emails are to the point, have a text and image balance and not overly promotional. 

7. You’re Sending Emails to Dead or Bought Lists 

The more spam complaints you get when sending to dead or bought lists, the more you hurt your sender reputation. Only use organic methods to build your list, and audit it regularly to weed out subscribers who no longer interact with your messages. Collaborate with your email service provider to help verify your domain.

8. You Haven’t Tested Your Emails for Spam Triggers

Prior to sending it, apply spam test tools to verify if your email is likely to end up in the spam folder. These tools scrutinize the composition of your email, your details, and the structure to ensure that the email spam triggers are not of yours.

9. Your Email Volume is Suspicious

The fact that the email flood comes out of the blue may make the spam filters think something is fishy. Deliver an adequate number of your emails gradually, and maintain a consistent number of them, then watch how the people respond to minimize their disapproval of your emails, which would prevent spam test tools from flagging them.

10. You Lack Personalization and Engagement

Incomplete and impersonal emails without user engagement are often forgotten, and the indicators of such events are the poor engagement rates. This sometimes means that the spam filters think that your content is worthless. Comply with email content best practices by personalizing the email to the recipient, segmenting the audience, and providing only the most suitable content.

Final Thoughts

Ways to avoid spam filters should focus not only on following technical instructions but also on sending valuable and meaningful emails. This will come as a result of identifying email spam triggers, maintaining a positive sender reputation, complying with CAN-SPAM compliance, and using spam test tools. Additionally, being mindful of spam words to avoid in your content ensures better engagement. These activities will enhance your inbox placement and help you connect with your audience efficiently.
