Protecting Yourself from Email Web Beacons

Tuesday, July 7th, 2020

Web Beacons (a.k.a Tracking Pixels) are images in HTML-formatted email messages that, when viewed, tell the sender of the message that you read it.  This mechanism of obtaining essentially covert confirmation that (a) your email address is valid, (b) the email got past your filters, and (c) you actually read the message, is pervasively used by Spammers to identify what addresses are reading their messages.  It is also used by email marketers to hep them measure the success of their email campaigns.

Save Yourself From “Yourself”: Stop Spam From Your Own Address

Friday, September 22nd, 2017

I just got junk email … from me!

It is surprisingly common for users to receive Spam email messages that appear to come from their own address (i.e. “joe@domain.com” gets a Spam email addressed so it appears to be from “joe@domain.com”).  We discussed this issue tangentially in a previous posting: Bounce Back & BackScatter Spam – “Who Stole My Email Address”?  However, many users wonder how this is even possible, while others are concerned if their Spam filters are not catching these messages.

How can Spammers use your email address to send Spam?

The way that email works at a fundamental level, there is very little validation performed on the apparent identity of the “Sender” of an email.  Just as you could mail a letter at the post office and write any return address on it, a Spammer can compose and send an email address with any “From” email address and name.  This is in fact extremely easy to do, and Spammers use this facility with almost every message that they send.

How do I fix the reputation of my IP address?

Tuesday, April 19th, 2016

It happens — you’re sending email messages without issue, and then suddenly they’re not being delivered, or they’re being tagged as spam.  A little digging reveals that the problem is that your “IP reputation” is now poor, and you need to fix it somehow.

This is our latest “Ask Erik” question, from Angelo Correa or Living Legacy, Inc.

How do I fix the reputation of my IP address?

What is IP Reputation?

Email service providers (e.g. AOL, Gmail, LuxSci) and email filtering systems (e.g. Barracuda, McAfee, Proofpoint, SenderScore) collaborate on and track the sending of unwanted email in order to reduce the blight of email spam that continues to plague the Internet.  Some of the significant factors that they track include:

  1. Quantity of email sent from your IP address
  2. The spam-like characteristics of these messages (based on spam filter analysis)
  3. The number of spam complaints by recipients of these messages
  4. The number of messages sent to invalid recipients or honey pots. Honey pots are email addresses that do not belong to real people and only exist as traps for senders who have acquired these email addresses via web site scraping or some other illegitimate manner.

Put together, these factors end up determining the reputation of that IP address with respect to the sending of email messages.  If the reputation becomes poor, then spam filters will start to quarantine or reject your messages, resulting in poor deliverability.
