4 Reasons Why Your Bulk Emails are Going to Spam

To solve a problem, first, we need to see where the problem is coming from. So here, before discussing how to send bulk emails without spamming, let’s check the main reasons behind spamming your bulk emails.

Here are the top 4 reasons why your bulk emails are going to spam—

1Low Engagement Rate

The webmail provider states that engagements are a big factor in whether emails land in the spam folder or directly in the recipient’s inbox. 

But how do they measure it?

To measure engagement rate, they track positive interactions like opens, clicks, and replies rate, as well as actions such as marking as important or moving out of spam. Negative actions like deletions or being ignored are also considered.

So, it is apparent that a low engagement rate can lead to your bulk emails ending up in the spam folder. 

2Not Including an Unsubscribe Link

If you are transparent while getting the list for subscription, you have to be transparent for unsubscription as well. 

Suppose your subscribers are no longer interested in your marketing mail and cannot find unsubscribed links. In that case, they might interact negatively, impacting your email authentication and leading to spam.

3Vague Subject Line

A vague subject line is one of the common causes of emails landing in spam folders. 

Many email marketers use misinformation or vague subject lines to attract recipients’ attention and encourage them to open the emails. However, this can lead to disappointment and even reports of spam or phishing.

Vague, unclear, and misleading subject lines contribute significantly to the problem of legitimate emails being marked as spam.

4Inaccurate Sender Information

If the sender’s information is not accurate and clear, recipients will likely perceive the email as spam.

Mistakes can happen, but it’s crucial to double-check the information provided in the ‘From‘ and ‘To‘ sections to ensure accuracy. Neglecting this step increases the probability of your bulk email being flagged as spam.

These are not the only reasons why your bulk emails might be going to spam. There are many more. Once you read the rest of this blog, you can discover more insights.

To avoid getting into spam, it is compulsory to be transparent while writing names and addresses. For this instance, it is suggested that you keep your email address simple, relatable, and meaningful. This will increase conversions and prevent landing on spam.

– Don’t Just Send an Image

Maintaining the Image in email is a significant priority nowadays. From UX to UI, images impact email flawlessly. 

Let’s see how this helps: instead of solely sending an image for better user interface interaction, aim for a balanced mix of text and images. This not only enhances accessibility but also ensures a more enjoyable reading experience for the recipient. 

Additionally, when using images in emails, avoid using rich media content. It often takes time to load, meaning the recipient might lose interest and leave without clicking on your target. So, always use compressed images with less rich media content. 

Furthermore, there is a nice option to add ALT text on your email images to let the webmail provider understand what you sent. 

These simple tricks make an email sophisticated enough that you will start seeing increasing CTR (click-through rate)

– Keep Your Email Mobile Friendly

Except for the millennials, Gen Z and the earlier generation are way smarter and prefer to handle emails from their mobile phones. 92% of email users are Gen Xers

So, making your email mobile-friendly is crucial so recipients can read and reply seamlessly, even from mobile devices. 

A survey of Gen Xers asked about emails and devices, and 85% of them admitted that they’ve used various emailing devices in the past January-February session to check or reply to an email.

– Optimize Your Email Content

When you are talking to someone over text instead of your voice, make sure your content sounds humble enough. To do this, avoid using uppercase letters. It often leads to shouting. opt for subdued text colors and fonts to contribute to a more modest and respectful communication style.

Besides being humble, write only the things that are valuable and relevant to the recipient’s interest. Otherwise, you might end up with a zero open rate.  

– Request Your Subscribers to Safelist You

When you send an email, it goes through many spam filters. Sometimes, the filter process wrongly marks your good email as spam and lands it in a junk folder. 

In this case, it is good to be transparent and ask your subscribers to safelist your email address so that every time you send them an email, it will land directly in their inbox. 

In fact, when bulk recipients safelist you, your email address gets passed through all spam filters easily.  

– Run Spam Test Before Sending

Testing before sending bulk emails is very important, not only for catching typos but also for avoiding spam filters.

You can check all the errors manually, but they may still leave room for doubt among internal technical staff. For this instance, it’s essential to run spam tests on your emails before hitting send. 

Several tools, such as Mailmeteor, SpamAssassin, and MailGenius, offer spam testing capabilities. Take the time to explore these tools and choose the one that best suits your needs.

– Employ a Good Email Marketing Tool

To send bulk emails with personalized content, you will need an email marketing tool to streamline the process and make it more manageable. But what tool would be suitable for your business?

Obviously, the one, which can save your money and deliver spam-free emails.

– Follow Up Emailing

Frequently, recipients may intend to engage with your email but end up forgetting about it over time. This unintentional neglect can negatively impact your email effectiveness. 

To mitigate this, consider implementing a follow-up email strategy to gently remind recipients of their initial interest. This approach not only enhances customer engagement but also reduces the likelihood of your emails being marked as spam.

– Send Relevant and Valuable Email

Email marketing is a customer-oriented method. It is a phase in which you can nurture your audience. That is why it is important to take care of your audience and send them relevant and valuable content through email. 

Avoid sending irrelevant content that may annoy recipients and lead to immediate unsubscribes. A higher unsubscribe rate increases the likelihood of your emails being marked as spam

So, to prevent this kind of negative reactions, segment your audience based on age, city, gender, interest, and preferences. It will help you to understand which content is more relevant to which segmented people. 

– Consider Technical Staff

Now, let’s delve into some technical aspects that significantly influence whether your email ends up in the spam folder or the inbox.

There are 2 things you need to check on to measure technical authentication. And these are the email verification process and IP reputation. Let’s see what these are and how they can help you to send bulk emails without spamming. 

Email Verification

To verify your email, follow these 3 steps from your mail service provider—

  1. SPF (Sender Policy Framework) verification – an email validation protocol that allows you to define a list of authorized IP addresses or servers. 
  2. DKIM (Domain Keys Identified Mail) Verification – is another email authentication mechanism that verifies the integrity and authenticity of an email message. It adds a digital signature to outgoing emails, allowing the receiving server to verify that an authorized sender indeed sent the emails and hasn’t been tampered with.
  3. DMARC (Domain-based Message Authentication Reporting & Conformance) – a policy framework that builds upon SPF and DKIM to provide an additional layer of email authentication and reporting.
Note: MailBluster is an email marketing platform that uses Amazon Simple Email Service (SES) for sending high-quality marketing emails and newsletters. And you can set up email authentication protocols using Amazon SES with higher security and compliance.

IP Address Reputation

An Internet Protocol (IP) address is a unique numerical identifier for an Internet location. 

In email communication, IP addresses play a critical role in determining the sender’s reputation and identifying spam.

Suppose your mailing IP address has a bad history record. This significantly raises the possibility of your emails being marked as spam. 

Additionally, there’s a risk of another entity utilizing your shared IP address to send spoofed emails, further damaging its reputation. This ultimately leads to your emails being filtered into spam folders. 

Note: MailBluster utilizes Amazon SES for email delivery, leveraging Amazon's established IP addresses for enhanced reliability and reputation.

– Watch Out For Spam Traps

ISPs (Internet Service Providers) use spam traps to catch spammers. These traps are real email addresses made to track and flag spam. 

If your bulk emails hit one of these traps, ISPs may block your IP address and “From domain,” reducing your chances of reaching inboxes. It could take up to a year to restore your sender’s reputation! 

Spam filters are the following defense, using criteria to block unwanted emails. They check emails closely to keep poorly written or irrelevant content out of inboxes.

Avoid Attachments

Frequently attaching documents to emails can sometimes trigger red flags for spam filters. It’s important to be mindful of this potential concern in your email communications.

While it’s not always a direct threat, it’s still best to avoid attaching files when sending bulk emails. Many recipients may hesitate to open attachments from unknown senders, which could pose a risk.

Adhere to the Laws Governing Email Marketing Practices

Sending bulk emails isn’t just about hitting “send” – there are laws you need to follow too! 

The CAN-SPAM Act regulates commercial messages in the US and allows people to opt-out. Canada has its own law, the Canadian Anti-Spam Law (CASL), which covers emails sent to or from Canada. (Federal Trade Commission)

Breaking these laws can lead to hefty fines, so knowing and following them when sending bulk emails is crucial.

– Maintain Email List Hygiene

Keep your email list clean of inactive and irrelevant email addresses, especially when you opt to send bulk emails without spamming. Sometimes, due to fallibility, wrong or duplicate emails get listed, which might result in bouncebacks or low engagement rates.

So what should you do? Crosscheck all the data manually. Keep updating your bulk email list. Remove and segment the inactive email addresses separately for retargeting

– Offer Both HTML and Plain Text Email

Make sure you have both HTML and plain text versions of your email. 

HTML emails, characterized by vibrant colors and images, appeal to a different audience compared to plain text emails, which are simple, no-frills messages. Incorporating both types can enhance the legitimacy of your emails with ISPs. 

Additionally, if your HTML email has errors, the spam filter might block it, but a plain text version can still get through.

– Proofread Your Email

It’s essential to crosscheck every aspect of your email before sending it. Even minor typos can increase the likelihood of your email being marked as spam. 

Therefore, it is paramount to leave no room for error. Take the time to thoroughly proofread and ensure the accuracy of your email content before hitting the send button.

Happy emailing!
