How to Know if Your Emails Went to Spam

Don't let your emails get lost in the spam folder. Learn how to spot the signs and ensure your messages reach their intended inboxes.
We've all been there - crafting the perfect email, only to find out later that it landed in the recipient's spam folder instead of their inbox. Sigh!

Before you hit that send button again, it's crucial to know how to tell if your emails are being marked as spam.

In this blog post, we'll dive into why emails end up in spam folders, reveal five indicative signs your email might be going to spam, and share tips on ensuring your emails reach their intended recipients.

So, let's get started!

Why Are My Emails Going to Spam?

Knowing what causes your emails to land in spam folders is half the battle; addressing these key areas will help improve your email deliverability and strengthen your communication with your target audience.

Here are the top three reasons why this might happen and a few solutions to help keep your emails from being marked as spam:

Content Issues: More than Meets the Eye

While it's important to make your emails visually appealing, using too many images or adding a bunch of links might flag them as spam. Also, watch out for spam-trigger words.

These can trigger spam filters, causing your emails to be treated as unwanted.

Stick to a more balanced and clean email layout, and reword your content whenever needed to avoid any suspicious phrases.

Low Engagement: It's Not Them, It's You (Maybe)

Subscribers not opening or clicking on your emails can actually harm your email deliverability. Email providers have algorithms that monitor user engagement, like open rates and click rates, to determine the quality of the emails they receive.

If your subscribers are not interacting with your messages, the email provider might conclude that your content isn't interesting and direct it to the spam folder.

To boost engagement, refine your email list, personalize your content, and include clear calls-to-action.

Reputation Matters: Mind Your Domain and Server Health

A good sender reputation can go a long way in keeping your messages out of the spam folder. Your email server, subdomain, or domain's reputation is crucial to how your emails are treated.

If your server has been used for spam or has weak security measures in place, that red flag could get your emails marked as spam.

Consistently monitor your email-sending practices and protect your domain and server's reputation to ensure smooth delivery of your messages.

5 Signs Your Email is Going to Spam

1- Your Open Rates Are Low

A sudden drop in unique open rates might mean your emails aren't just being ignored - they could be marked as spam. To keep your email outreach effective and well-received, it's important to stay on top of these trends and figure out what's happening.

Monitoring email open rates over time is crucial for a successful email campaign. Doing this allows you to spot any significant fluctuations or ongoing low-open rate trends.

If your open rates are consistently low or have dropped significantly, it's time to take a closer look and determine what's occurring. Remember, a helpful and engaging email strategy keeps your audience interested. Consider changing your approach to create more enticing subject lines and content that resonates with the recipients.

Examine and adjust your email strategies to be well on your way to boosting open rates and keeping your messages from landing in the spam folder.

2- Your Bounce Rates Are High

If you've ever noticed high email bounce rates, it might be time to pay attention. Your emails could end up in the spam folder, which spells bad news for getting your message across.

In email marketing, understanding the difference between hard and soft bounces is crucial to maintaining a clean and updated list, reducing the chances of being marked as spam.

Hard bounces are the worst kind, as these indicate that you've sent an email to an invalid address.

Unfortunately, this increases the likelihood of your emails being seen as spam.

On the other hand, soft bounces simply mean you've encountered a temporary delivery issue. This could be caused by a recipient's mailbox being full or the server being down temporarily.

Now, no one likes receiving unwanted emails, and cleaning up your email lists is your best bet to avoid being marked as spam and ensure your message reaches the intended recipients.

Here are some practical steps to consider:

  1. Regularly update your email list by removing invalid email addresses and fixing typos.
  2. Reach out to your recipients to confirm their contact information.
  3. Keep track of bounce rates so you can identify potential issues early on.

3- You Send Too Many Images or Links

Spam filters are smart and designed to look for certain content that indicates spam. If your email is packed with images, links, or trigger words associated with spam, it will likely be flagged. To avoid this problem, it's important to balance images and text in your email.

You don't want it to be too image-heavy because that can raise a red flag for spam filters. Plus, you may want to watch out for excessively promotional language, which can also set off alarm bells for those annoying spam filters.

To deliver a more human-written and engaging email, try to make sure your emails are thoughtfully composed, with a good mix of visuals and well-written content.

Avoid the common mistakes mentioned above, and you'll have a better chance of staying clear of the spam folder and reaching your subscribers.

4- You Bought Your Email List

If you've ever considered buying an email list to grow your business, hold up!

This may not be the best choice for your marketing efforts, and we're here to help you understand why.

Purchasing email lists might seem like a quick and easy way to expand your reach, but in reality, it can cause more harm than good.

When you buy an email list, you are potentially harming your business reputation and can significantly increase the chances of your emails being marked as spam. That's definitely not what you want, right?

So, how can you grow your email list without resorting to these questionable tactics? Building your email list organically is the way to go.

Think about it - when you get people to opt-in, they express genuine interest in what you offer. This is a great chance for you to provide value through relevant content and offers (and who doesn't love a good deal?).

So, ditch that purchased email list and start inviting website visitors to join your mailing list. This approach might take a bit longer, but you'll end up with higher-quality leads more likely to convert into customers.

5- You Are Not Warming Up Your Email

Many salespeople and marketers don't realize the importance of warming up their email, especially regarding new accounts or high-volume sending.

"Warming up" your email involves gradually increasing the number of emails you send over time. This helps establish a positive email reputation and reduces the likelihood of your emails being flagged as spam.

Instead of diving right into high-volume email sending, it's much better to take things slow and warm up your email. Doing this gives your email provider time to recognize your sending patterns and trust that you're not a spammer.
