You Opened An Email (With Attachment). Here’s What Happens | Data Overhaulers (2022)

Oh no! You accidentally clicked on a spam message in your inbox. You closed it quickly, but now you might wonder what happens if you open spam email? Is it unsafe to have clicked on one of the messages? Is opening an email dangerous?

There is little danger to opening a spam message as long as users do not open links or attachments. If your email app or webmail automatically loads images, some tracking can occur. Downloading attached files or clicking linked text or images opens users to threats like malware, ransomware, or phishing.

We’ve all been warned to watch out for suspicious emails. Even when we have a sound spam detection system, the occasional email will make it to our inbox and even under an accidental click.

Let’s go over what happens if you open a spam email on iPhone, or Android, webmail, or email client.. We’ll also detail ways to protect your account.

Before Spam Arrives In Your Inbox

Spammers gain a little insight even before their message reaches your inbox.

An email sent to an invalid address will be rejected and bounced back to the sender. Spammers know that your email account is valid by watching for bounces.

Unfortunately, there’s not a great way to defend against this. Fake bounce, auto-responders are ineffective.

Most users have their email address tightly linked to their actual inboxes. This means we cannot prevent a spammer from discovering your email address is valid.

Heads up: Later, we’ll go over ways to separate your email address from your actual mailbox where you manage emails.

What happens next is scary, but there’s a straightforward solution.

Can spammers tell if you open an email?

Spammers can tell if you open an email when you or your email application interact with their message. When your webmail or mobile email app automatically downloads remote resources like photos or graphics, the spam sender immediately knows their content was viewed.

Most email users prefer auto-loading images, so emails look nice when they click to read messages. This is a mistake when it comes to defending against spammers.

How does this work:

A spammer designs an email with embedded images to make the message look professional. They host or store these photos or graphics on their server. When your email app, mail reader program, or webmail requests these images, the sender receives numerous data points while sending the email’s graphic elements.

Here’s a list of the most common bits of information revealed when you auto-load images:

  • IP Address: This is the internet address of your home router, cellular provider, or work connection that can be used to derive the following:
    • The approximate geographic location is usually down to a city level.
    • Your internet service or mobile phone provider.
    • If you’re at work, the spammer can find the name of your company.
    • The type of connection you’re using, like DSL, fiber optic, mobile data, etc.
  • Device type like a mobile, tablet, desktop/laptop.
  • Operating system like Windows, Mac, Chromebook, or Linux.
  • Which browser or mail reader app you use.
  • Device time and time zone.
  • Screen size.
  • Device language.

The way to stop giving this type of metadata to spammers is to turn off automatic image downloading in your mobile email app, desktop email client, or webmail. Most services offer this function. Remember to avoid opening suspicious emails. When in doubt hit delete. Once you do that you close the door to possible harm.

Later on, we’ll give you quick instructions on stopping auto-loading images for some popular email apps and webmail sites. But, what happens next if you open a spam text?

The same rules also apply to opening suspicious texts. A spam text message can install malware that can collect information from your phone. Once the cybercriminals have your information, it can be sold to marketers or even identity thieves.

When You Reply or Forward Spam


Comedian James Veitch gave a hilarious Ted Talk on what happens when you reply to spam.

It’s obvious that it’s not a good idea to directly reply to spam emails despite Mr. Veitch’s sketch from above.

You confirm that you’re a willing participant in an email conversation with fraudsters in the least severe instances.

In the worst scenarios, you could inadvertently give away personal information that can compromise youronline privacyor security.

For the instances when you receive an email from one of your known contacts that looks suspicious, it is best to start a new email or instant message/text your contact. Use this new, separate channel to ask if they sent an email with the suspect subject. Do not reply or attach the original spam email.

However, the worst thing you can do after opening a spam email is the most dangerous.

Opening an Attachment or Clicking a Link

Can you get a virus just by opening an email?

It is not typically possible to get a virus just by opening an email. The programming behind emails is too basic, requiring attached or remote resources to load. Users need to click a link or open an attachment from a malicious message to start an infection on their computer or smartphone device.

Dangerous Attachments

Some dangerous files are fairly obvious such as zip files or executables like programs or mobile apps. These should never be opened unless received from a highly trusted and confirmed sender.

Other attackers send spam containing files whose native format includes automation. For example,PDFs can contain viruses.

The fortunate problem with sending malware as an attachment is that many email systems have sophisticated detection software that scans attachments to find viruses or other malicious files.

This works against most attackers. Spammers instead entice users to click a text or image link.

Deceptive Text or Image Links

Links within emails are an invaluable tool for most legitimate situations.

Emails are size-restricted and do not have automatic or dynamic content updates. It’s often more efficient to send a user to a web page containing the most up-to-date information.

A link can be a bit of text or a clickable image. This hides the destination, which may be an internet site operated by spammers or fraudsters.

Over the years, there have been several very creative ways to fool the average email user. Many of these attacks work by exploiting users’ inattentiveness to internet addresses. These are often linking to a phishing website or a remotely-hosted piece of malware from a site posing as a valid and well-known site.

If you’ve already clicked on a phishing link, you’ll want to know what happens next. Read this article next.

Here, I’ll pick on GoDaddy as an example only.

  • Purpose-Registered
  • Typo
  • Look-Alike Domains:GoDа[replaced the English letter “a” (U+0061) with the Cyrillic letter “а” (U+0430)]
  • Sub-Domaining:
  • DNS Poisoning: Requires an attack at top-level domain lookups to replace the IP address ofGoDaddy.comwith an attacker’s address. This propagates across the Internet for a short time.

Opened a Spam Email on Android?

Here is what to do if you open a suspicious email attachment or email:

Disconnect Your Device

Disconnect your phone from the internet. This will reduce the risk of malware collecting and sending data from your phone. It will also prevent the malware from spreading to other synchronized devices or someone from accessing your phone remotely. Or you can simply enable Airplane Mode.

Perform System Scan

Run a scan of your android device with reliable antivirus software. It is a protective layer that helps keep malware off. Follow all the instructions to do a full search of your device and quarantine or remove any virus. If you don’t already have anti-malware, you can safely install one from the Google Play Store.

Change All Passwords to Avoid Further Damage

Malware is good at collecting data such as bank account numbers, credit card numbers, usernames, and passwords. So, change all passwords for shopping accounts, online banking, social media, and email. And do not use the same password for all your online accounts unless you want to make accessing your accounts a walk in the park. The smartest way to do it is to use a password manager. It allows you to safely store unique, passwords for your accounts.

Can You Get a Virus from Opening an Email in Gmail?

No, you can’t get a virus by just opening an email in Gmail or any other provider. Clicking on links and attachments is where there is a problem. Some emails have attachments and programs as links and attachments to malicious sites awash with scams and malware. Only open attachments that you trust. Even if somebody you know sends you a file with a .exe or any other similar program, don’t open it. Also, do not run any programs that try to download directly onto your computer after clicking on a link.

That said, Gmail uses a proprietary virus scanner to scan all emails. The application blocks any email that it finds a virus in or a suspicious file.

What if I Opened a Spam Email on my iPhone?

iPhone can’t get viruses. iOS viruses are only theoretical, not practical. If your iPhone says it has malware or virus, it is most likely something else.

Protecting Yourself

What do you do when you open a spam email?

  1. Close email messages without clicking links or opening attachments.
  2. Mark the email as spam or junk to help train detection software.
  3. Run a malware or virus scan on your desktop or laptop computer.
  4. Watch for emails or texts from friends, family, or colleagues about strange emails.
  5. Notify a manager or IT department staff member in a work environment.

A few more quick tips:

  • Be suspicious of emails from your contacts with odd subjects, or the email body text isnot right.
  • Use throwaway email addresses fromNadaorSimpleLogin
  • Turn off auto-loading images in your email app or webmail

Turning off automatic image loading in desktop, mobile, and webmail services increases security. This results in the need to manually click a link or button in each email message to load externally hosted graphics.

This is an excellent extra step despite emails looking a little bland. It allows you to decide each time if you’re willing to risk your privacy and security.

If you’ve clicked into a message accidentally, simply close and mark it as spam or delete it. You’re safe as long as you’ve not clicked an attachment or link within the email.

Run your computer’s malware scan if you’ve opened a spam attachment or clicked on a text or image link that opened your browser to a website.
