What to Do with Suspicious Emails

If you haven’t disabled auto preview images in your inbox then those spammers can track sent emails are opened. What happens is whenever you receive an email there are various images and text. When you open any email it will load all those images for you and this results in sender to know when the email was opened.

But if you disable the external images to display automatically there is no way someone can know when the open was opened.


Also, Don’t click any links in those spam emails those can link might first send a signal or link click to spammers.

Make sure don’t always click unsubscribe if you don’t know the sender or email looks suspicious because sometime spammer sends emails to a large number of peoples list randomly generated or picked from other sources.

When you click unsubscribe that confirms that email address exists you will end up receiving lots of spam emails.

Don’t Put Your Email Everywhere

Don’t mention your email address on the internet (social media, forums, profile page) because that way you are giving away your personal email to spammers openly.

If you really have to provide an email address use other third-party services that will mask your email address.

Some email service provider like yahoo mail and proton mail provide this functionality inbuilt where you can create a new email address attached to the current email.

How To Use Your Personal Email

Don’t use your primary email address to sign up on websites that you don’t trust, use your secondary or temporary email address for websites where you are not sure about the product or you just want to try it for once.

Right now there are so many websites try to capture the email address of potential clients (lead generation) so they can use different tactics like live chat (Drift, Intercom etc), giveaway & contest to get your email address.

live chat get notified by email

Tip: If your intention to use any service(newsletter, freebies alert, job alert) is temporary then don’t use your personal email.

No doubt big companies can protect your data more securely than small companies but there is always a chance of data breach so be safe don’t use primary email for everything(for social, banking, newsletter, office).

Even some big companies share your data with partner companies you can find these details in there privacy policy.
but who reads privacy policy while signing up for a newsletter.

Tip: if you want to check any websites privacy policy quickly you can check out Verge’s video on this topic.

What To Do With Spam Emails

Most of the spam filter can be done at your email client level, so use these filters and rules effectively to separate spam and important emails.

Mark spam emails as spam if they reach your inbox

Mark not spam to important emails or mark them as important if they are

mark not spam if true

If you start to receive spam from a contact you know or it looks like that email is from their email address but it’s not, inform them because there are chances that their account is compromised.

Why Use Your Secondary Email address

Keep your primary email clean and close to your heart do not give it to everyone, reveal it only your close friends and family member.

For day to day interaction and promotional stuff use your secondary email address, that way your main email inbox will clean always.

For bank accounts, financial accounts always keep your id separate do not use it for signup on every website.

Third-Party Services For Reducing Promotional & Junk Emails

All emails are not always spam sometimes there are websites who might send you a lot of emails but they are not spamming these are promotional emails.

Use this as last resort or in case you don’t have time to clean your inbox because of the large number of emails. By using third party software you can clear the clutter and unsubscribe those promotional emails, after that if you receive spam or promotional emails just block them and make sure to mark all spam as spam.

You may still receive confirmation of unsubscription.

Keep in mind there is no 100% assurance you are going to be unsubscribed always.
