What is one email subject line mistake that could send an email directly to the spam folder?

As an Enterprise SaaS sales rep, I'm well versed in bypassing spam filters after sending tens of thousands of automated cold emails, and hundreds of personalized cold emails over the past several years. Anything that mentions price or cost will be flagged by Google as going directly to spam. Dollar signs ($$$), FREE in capital letters, "Act now", "Buy Now!!!", "100% discount", or anything with excessive punctuation and/or urgency will send you straight to email jail. How do I know? I've A/B tested all of the above phrases, and similar variations, in different cadences, from different email domains. And any time I've tested any subject line with even a hint of urgency, the open rates are abysmal. My advice is to keep your subject line low friction and low pressure, and relevant to whatever email it is that you're sending. At one company I worked for, out of all the different subject lines we tested and tried, the best performing one was "Intro." Sometimes simplicity is best!

Since teaming up with Michelle Paulhus, our E-Commerce & Retention Director (aka guru of all things e-commerce and email), we agreed to ditch the salesy subject lines. We keep them short, sweet, and just plain fun—sometimes riffing on a joke that pays off in the newsletter, asking a ridiculous question, or something that seems random but sparks curiosity in the email. Keep them fresh, fun, and full of surprises!

There's a long list of words and phrases that will sweep your message into the spam folder before your reader ever gets to view it. These phrases typically have to do with creating false urgency ("act now!") or false promises ("100% free"). Spam filters are imperfect, and sometimes they can bury legitimate offers out of caution, but they are designed to reduce the risk of fraud or harm to the reader. So consider your word choice before you hit send. You don't want your business to get lumped in with any shady activity. Even if your email isn't automatically sorted into spam, your subject line could earn you a one-way ticket out of your reader's inbox if you're not careful. With so many people feeling overwhelmed by the sheer volume of messages they receive, a little empathy can go a long way. Instead of writing subject lines that ask your reader to spend or take action, consider how your email can help solve a problem they're facing. Demonstrating that you understand your audience can make your emails more relevant and less expendable.

Spammy words A critical mistake is using spammy words in subject lines. These words can trigger spam filters, causing your emails to be missed by your audience and harming your sender reputation. Words like "free," "guarantee," and "limited-time offer" are common culprits. Steering clear of these terms not only helps your emails reach inboxes but also maintains your brand's credibility. Crafting engaging yet straightforward subject lines without these triggers is key to successful email deliverability and maintaining a positive relationship with your audience.

One sure-fire way to get your emails caught by the most basic spam filter is not customizing your subject lines at all. If you have your contact's name or business name, include them in the email subject to make your emails more unique and look less like spam.

I've written thousands of content pieces online since 2011 and one of several things that has helped me stand out from the rest is avoiding capital letters & exclamation marks. I'm guilty of it too. I used to add exclamation marks to look cool. The same applies to email subject lines as well. People have short attention spans and when they see capital letters in subject lines, it sure gets them to pay attention but also raises red flags. I've never opened an email with all-caps subject lines. Imagine me writing this all caps or title case with an exclamation mark! Not convinced yet? Here are some logical reasons: - Spam triggers: The email algorithms look for capitalization in subject lines. Subject lines with capitalization are the first to land in the spam folder. - Perception: ALL CAPS is perceived as shouting in digital space. Didn't you imagine me yelling at you at the beginning of the sentence? - Professionalism: It never sounds professional to use capital letters repeatedly. It abrupts the flow.

I received this a LOT - 'Sorry I missed your email,' says the person who responded three weeks later. One email subject line mistake that could send an email directly to the spam folder is using vague or irrelevant subject lines, such as "Sorry I missed your email" or "Following Up". These subject lines may not catch the recipient's attention and could easily be mistaken for spam, causing the email to be deleted or sent directly to the junk folder. For me, this is one of the most frustrating email mistakes. Not only does it waste my time and clutter my inbox, but it also shows a lack of professionalism and consideration for others' time. If a marketer thinks that "sorry I missed your email" is a suitable subject line, they may not have taken the time to understand their audience and tailor their message accordingly. I always say this to my team - if you want to be successful in email marketing, put yourself in your recipient's shoes. Would you open an email with such a vague and uninteresting subject line? Probably not.

All caps and exclamations. I know you might be excited to tell us some news, but anything with all caps tends to push emails directly into the spam folder, rendering your excitement null and void. In addition, emails that break through the spam filter with an all-caps subject line receive a reply 30% less often than those that do not. Tied together is the use of exclamation points. Digital marketers like to create a sense of urgency so users feel the urge to open their emails, but the combination of all-caps and exclamation points will send your emails directly to the spam filter.

I've learned the hard way about email subject lines. One major misstep that can send an email straight to the spam folder is referencing unclaimed winnings or prizes. I remember crafting a promotional email last spring, excitedly titling it 'Claim Your Free Workout Prize!' The intention was genuine, offering a free resistance band to our loyal customers. However, to my dismay, most recipients never saw it; our analytics later revealed the email had been largely flagged as spam. It was a sobering reminder of the fine line between engaging and misleading language, and since then, I've been more cautious, focusing on clear, direct subjects.

Using misleading or deceptive language in an email subject line is a common mistake that can cause the email to be flagged as spam.This includes using clickbait phrases such as "URGENT" or "ACT NOW", which can trigger spam filters and make your message look like a promotional or phishing email.Other mistakes to avoid in subject lines include using excessive punctuation, all-caps, and multiple exclamation points. These tactics are often associated with spam or overly aggressive marketing messages.It's important to remember that your subject line is the first thing a recipient sees when they receive your email. If it looks suspicious or unprofessional, they may immediately mark it as spam without even opening it. To avoid this mistake, make sure your subject line accurately reflects the content of your email and doesn't make false promises or use exaggerated language. Keep it concise and to the point, and avoid using spam trigger words like "free" or "guaranteed".

A big mistake in email subject lines is using "RE:" to imply an ongoing conversation when it’s the first email to a lead. This tactic is misleading and can be perceived as annoying and pushy. It's a shortcut that might seem clever, but it often backfires. Leads feel tricked when they open the email, realizing there's no prior conversation. This approach can damage trust and credibility, crucial in building relationships with potential clients or partners. Being clear about the purpose of your email respects the recipient's time and intelligence.

Using loads of emojis. I'm not sure I like emojis in a subject line at all, but there's some evidence to suggest it can improve open rates. In those cases, I think it's about how you use them, placement, word choice, context and so on. But a row of emojis looks super spammy and out of place. Especially in a workplace inbox. If you're going to use an emoji, do it intentionally and with care. For example, if you have a regular newsletter, then using the same emoji each send can mean that it's easier for the reader to pick out when that newsletter has arrived at a glance. Or, if you have a big announcement, then a party face or trophy emoji is appropriately celebratory. Just be sparing!

Failing to provide an easy-to-find unsubscribe option in the email can lead to it being marked as spam. Email recipients expect to have the ability to opt-out of promotional emails, and omitting this option can raise suspicions of spam. To avoid this mistake, ensure your emails include a clear unsubscribe link or button in compliance with anti-spam regulations. Neglecting this requirement not only risks the email being flagged as spam, but it also negatively impacts your reputation and recipients' trust in your brand.

One common mistake that can land your email straight in the spam folder is overdoing it with emojis in the subject line. While emojis can add a fun and visually appealing touch to your message, going emoji-crazy might trigger spam filters. Keep it balanced, use emojis sparingly, and make sure they actually enhance your subject line rather than overshadowing your message. As a marketer myself, it's all about finding that sweet spot between creativity and professionalism to ensure your emails not only reach the inbox but also get the attention they deserve.

Including excessive symbols, words like "make money fast," and urgency may trigger spam filters, as they resemble common spam tactics. This subject line is likely to be flagged due to its use of multiple dollar signs, urgency, and promises of quick financial gain. Spam filters often target such elements to protect users from potentially harmful or deceptive content.

Optimise Subject Lines to Avoid Emails Landing into the Spam Folder Using overly aggressive or spammy language in the email subject line, such as excessive capital letters, multiple exclamation marks or words like "guarantee" or "free," can trigger spam filters. Creating a generic or assertive subject line may diminish the email's relevancy. A run-on subject line may not grab the reader's attention, whereas one-word subject lines seem to be lazy and thus spammy. For example, a subject line like "AMAZING OFFER!!! WIN FREE MONEY NOW!!!" will likely be flagged as spam. Maintaining a professional and genuine tone ensures that emails reach the recipient's inbox rather than being diverted to the spam folder. For instance, using words like "survey" may prompt spam filters. Therefore, crafting subject lines with clarity, relevancy, and professionalism is essential to convey your message and avoid being flagged as spam.

Avoid using excessive or misleading punctuation in email subject lines. Excessive exclamation points, question marks, all caps, and symbols like $, #, %, or & can trigger spam filters. Keep subject lines clear, concise, and professional. Use punctuation sparingly and avoid all caps and excessive symbols.

Using trigger words commonly associated with spam, such as "urgent," "free," or excessive use of exclamation marks, could lead to an email being flagged as spam and relegated to the spam folder. It's crucial to craft subject lines that are clear, relevant, and avoid typical spam indicators to ensure successful delivery to recipients' inboxes.

"Subject: ""Free Money! Just Click Here!"" One email subject line mistake that could send an email directly to the spam folder is using overly promotional language or making unrealistic claims. Spam filters are designed to detect and filter out emails that appear to be spam or scams. Using subject lines like ""Free Money! Just Click Here!"" may trigger the spam filters and cause your email to be sent directly to the spam folder. It's important to use subject lines that are clear, concise, and relevant to the content of the email. Avoid using excessive punctuation, all caps, or misleading statements that could raise red flags for spam filters. Remember, honesty and authenticity are key to avoiding the spam folder and building trust with your recipients."

One email subject line mistake that could send an email directly to the spam folder is using all caps in the subject line. While it may seem like a good way to grab attention, in reality it can be perceived as shouting and can come across as spammy. It's important to use proper capitalization and avoid excessive punctuation or special characters in your subject line.
