How to Prevent Your Email from Being Flagged as Spam

At some point, almost every website owner will want to run an email campaign to help promote their site or business. It’s a great way to get the message out to as many people as possible, but it’s not as effective as it used to be.

Why? The answer is spam filters.

Spam filters have been designed to flag and remove suspicious emails that could be part of a scam or a means of delivering malware, and sometimes these filters might mistakenly see your emails as a threat.

When a filter incorrectly identifies your email as spam, this has the potential to put a serious dent in your audience numbers. Many people on your email list might never even receive your emails.

In this article, we’ll look at nine ways to improve your email marketing strategy so your messages won’t get caught in the spam filter trap.

1. Make Your Email List Organic

It’s a very common scenario—as a website owner with a great product or message, you desperately need to get the word out, but your email list is lacking. The few hundred email addresses accumulated organically over the years aren’t going to cut it.

You know that a much wider audience could benefit from your message, so what’s the solution? If you’ve considered buying a list of email contacts, don’t do it.

Buying an email list is a problem for many reasons. For one thing, it’s a cold call style of emailing, which can be seen as a spamming tactic. It can have adverse effects on your email address and subdomain.

You need to grow your user base naturally, emailing willing participants rather than just doing it randomly and hoping for a hit.

Building a mailing list organically sounds difficult, but it really isn’t. All you need to do is continue engaging with your users, fans, and customers just like you’ve been doing, but with a few small changes designed to grow your audience.

Social media platforms such as Twitter and Facebook are excellent ways to attract more people to your site. Once you’ve built an audience through organic interactions, you’re more likely to be able to convert people into willing participants for your emailing campaigns.

2. Write Email Content with Spam Filters in Mind

Marketing has a language all its own, full of salesy clichés. Even if you resist, it’s easy to find yourself using some of the most worn out pitches.

Advancements in technology have enabled spam filters to find this kind of language. They use sophisticated algorithms to scan your email and determine what it’s about based on the wording you’ve used.

What does that mean for your content? Here are some useful pointers to think about the next time you find yourself crafting a campaign for your email subscribers:

  • Don’t overuse exclamation points!!!
  • Avoid words like “free,” “bonus,” or “sale.”
  • Avoid tired clichés like “Act now!” or “Call us today!”
  • Limit the use of images in your emails.
  • Enable text alternatives for all your images.

These may seem like small considerations, but addressing them will help your emails make it past spam filters and get to your valued users. You might find it a little difficult in the beginning to shrug off old habits, but the benefits in the long term are worth the initial effort.

3. Email Your Subscribers, You Have Their Permission

The best way to be sure that the people who receive your emails actually want to receive them is by restricting your email list to people who have subscribed. Your subscribers have given you permission to send them marketing emails.

Adding a Subscribe button to your site is a great way to attract subscribers, and having it in your email signature is smart, too.

If your brand is compelling and you regularly ask your audience to subscribe, you’re bound to start racking up more users, and it will happen as a normal part of your daily business activities.

4. Let Subscribers Leave If They Want To

It’s important to give people a way to unsubscribe from your emails.

Nobody likes feeling trapped, so you need to make unsubscribing just as easy as subscribing. If your messages aren’t engaging your audience, then you owe it to them to have an opt-out feature. If they can’t unsubscribe when they want to, users will become frustrated and will mark your email as spam. This will alert the filters, hurt your brand, and give you a reputation as a spammer.

Even if you have engaging emails that your users genuinely enjoy, think about the frequency of your mailing routine. If your email schedule is too aggressive, you’ll end up annoying a large percentage of your audience. If people feel you’re sending too many emails, they’ll want a way to unsubscribe.

GIving users an easy way to unsubscribe will help you avoid having your emails reported as spam.

5. Keep Your Email Marketing Strategy Fresh

The changing tastes of your audience along with ever-evolving marketing trends make it crucial that you adapt your email marketing strategy to stay current.

The techniques that worked last year might not be effective anymore. You need to update your approach and always keep up with the latest techniques and trends in digital marketing.

You can start with really simple things. Check out your email metrics and look at how your campaign is performing. Find out what’s working by monitoring traffic levels after an email campaign. Keep the strategies that work, ditch the ones that don’t. If you find that you’re getting poor results, then you must change your techniques accordingly.

Look at your email strategy with a critical eye. Be honest with yourself. If something’s not working, you need to acknowledge it as soon as you can and make the needed changes. Remember what Albert Einstein said, Insanity is doing the same thing over and over again and expecting different results.” If your email marketing isn’t working, change your approach.

6. Get Whitelisted

Getting on a user’s whitelist (their list of pre-approved email senders) is optional, but it can be highly effective in making sure your emails don’t get flagged as spam.

It’s OK to ask your users to add your email address to their whitelist. You can make the request a call to action in your email signature or somewhere prominent in your email that is easy for them to click on.

This does not have to be a desperate plea. You can make the case that, if your fans wish to continue hearing from you, then whitelisting your email will be a massive help. It’s similar to how YouTubers always ask you to “like, subscribe, and hit the notification button” at the end of their videos.

7. Self-Test to Verify that Your Email Isn’t Spam

Self-testing your email campaign means subscribing to your own emails as a way to make sure they aren’t getting snagged by spam filters. You should sign up for your emails, enable a strict spam filer, and watch what makes it through.

It’s smart to be constantly analyzing the effectiveness of your email campaign so that you’re aware of its real-world performance. This helps you to prepare for major campaigns and specials that you plan to roll out.

If your campaign fails because you didn’t realize that all your emails are getting marked as spam, you’ll lose out on a great opportunity to reach a new audience. Or worse, if you pay for premium content and services to improve your email campaign, and then all your emails get caught by spam filters, you’ll have wasted your investment.

You should self-test often, and make changes based on the results until you’re happy with the outcome.

8. Be Honest in Your Emails

You must make sure that all of your messaging is honest. For example, your subject line must accurately reflect the contents of your message.

Don’t fall into the trap of writing a clickbait-style subject line for a message that doesn’t relate to that subject. Trying to fool users with a misleading subject will have them looking for the Unsubscribe button.

Another dishonest email tactic that should be avoided is masking your email’s routing details. Using an email persona is one thing, but pretending to be from a different domain to get around a blacklist, for example, is unethical. In some countries, it’s illegal.

Unethical practices like hiding your true email identity can get your brand into serious trouble and give you a reputation as a spammer.

9. If You Get Blacklisted, Clear Your Name

Sometimes, you can get blacklisted at no fault of your own. If you share an email server with a spammer, you can get your email address blocked. You’ll be viewed as guilty by association, just because of a shared domain.

Using a premium service provider will help you avoid this kind of complication, so consider your options when setting up your email service.

If you’re wrongly blacklisted, there are ways to appeal. You can find out what your current email status is by using tools like mxtoolbox, which will give you a brief overview of your current reputation. If you start receiving notices that your emails have been rejected, you can quickly check on your status and take corrective action.

Keep Your Emails Spam-Free for Better Communication

As with most things related to digital marketing, executing an effective email campaign can be challenging. If you take a hard look at your current strategy, you can find ways to ensure that your emails will never be filtered out as spam.

When you make small changes to your messaging style, you’ll not only get past spam filters but also become a better communicator for your brand. Your email campaigns can be a game changer, helping to build relationships with your users and get you more business.
