Differentiate Between Regular and Spam Emails

As anyone who has ever opened their inbox to a flood of emails knows, not all messages are created equal. Some emails are important and relevant, while others are little more than digital junk mail. So how can you tell the difference? Here are a few key ways to differentiate between regular and spam emails:

  • The sender: Spam emails often come from unfamiliar or inconspicuous addresses, while regular emails usually come from people you know or businesses you have interacted with before.
  • The subject line: Spam subject lines are often vague or contain strange characters, while regular email subject lines are specific and accurate.
  • The content: Spam emails often contain grammatical errors and typos, and they may try to sell you something or redirect you to a website full of ads. Regular emails, on the other hand, will generally be well-written and free of obvious commercial intent.

By keeping these guidelines in mind, you can help to cut down on the amount of spam in your inbox and make sure that you only receive emails that are truly worth reading.

What Triggers the Spam Filter?

Have you ever wondered what triggers the spam filter? Most of us have accidentally sent an email to the spam folder at some point. Whether it was an important work email or a message to a friend, it’s frustrating to see it end up in the spam folder. So, what causes this to happen?

Let’s have a look at what triggers the spam filter:

When an email is sent, it goes through a series of server checks.

  • The first check is for the sender’s IP address. If the IP address is on a blacklist, the email will automatically be sent to the spam folder.
  • The next check is for keywords that are commonly found in spam emails. If the email contains any of these keywords, it will also be sent to the spam folder. 
  • In the last check, the server will check for suspicious links or attachments. If any are found, the email will be sent to the spam folder.

Why Do Spam Filters Blocks Regular Email?

Have you ever wondered why your email provider’s spam filter has a tendency to block regular email?

It’s not because the filter is broken or picking on you specifically. In fact, there’s a very good reason for it. Spam filters use a variety of criteria to determine whether an email is legitimate or not.

One of the most common is the content of the email itself. If an email contains a lot of links, certain keywords, or unusual formatting, the spam filter will flag it as potential spam.

This is why your regular email sometimes gets caught in the filter because it doesn’t look like other emails that the filter is used to seeing. However, there’s no need to worry.

Most spam filters are very good at their job and will only block a small percentage of legitimate emails.

So, while you may occasionally have to search your spam folder for that important message, rest assured that your email provider is doing its best to keep unwanted messages out of your inbox.

How to Avoid Spam Filters When Sending Emails?

Email spam filters are getting more sophisticated every day, and it can be a real challenge to make sure your messages get through. Here are a few tips to avoid the spam filter:

  • Avoid trigger words or misleading subject lines: Spam filters are on the lookout for certain red flags, like all caps or exclamation points in the subject line. Be creative with your Subjects, but don’t try to trick people into opening your email. 
  • Ask your subscribers to add you to their address book: This is a great way to ensure that your emails always get through. Just include a simple request in your next email asking people to add you to their address book.
