Caching vs. Tracking: Meaning and measurement of open rates in e-mail marketing

For most marketers, open rate is one of the most important metrics. But why is this the case? And how is open rate mesured? Are high deviations between the different ISPs (e.g. Yahoo, Hotmail) a reason to worry?

In December 2013, GMail announced an interesting update: Image Caching was introduced. Per default, images should be displayed (instead of suppressed as before). For security reasons, images should be scanned for malware , therefore caching was a necessary measure to be taken.

A tracking pixel is a transparent image of 1×1 pixel size. With it’s help, openings and META-data like geo-location can be tracked.

How delivery rates are calculated – and why there’s no simple answer

We could talk about Deliverability as everyone, we choose to talk about it as no one.

Today, more than 60% of the whole email traffic is spam (statistica, 2016). This means ISPs have more chance to receive a spam attack, or a risk to his customer, than an important emailing.

Your ISP can proudly show it has a 99% Deliverability rate, nevertheless evidently you receive your emails in the junk folder, or you are blocked to a specific ISP. How can this be? Why is my Deliverability so high on some ISPs and not on all ISPs? Why do I have 99% Deliverability rate but the ISPs still consider me as a spammer? The indicators are just not calculated the same way…

Lesson 1, the history of email

Lesson 1, the history of email

Electronic mail, commonly referred to as email or e-mail since 1993, is the method of exchanging messages from a sender to the receiver on a network, generally the internet.

The first email was sent in 1971 by a man called Raymond Tomlinson over the ARPANET. He implemented the first email system that sent an electronic message from one computer to another, in doing so he also coined the ‘@’ symbol to seperate the user name from the senders domain, which has been used ever since.

The ARPANET is famous for securely transferring protected military files between networks. As the ARPANET expanded from 4 research labs to several others, different models of computers were connected, thus creating compatability issues.
The solution was a set of protocols now referred to as TCP/IP (Transmission Control Protocol/Internet Protocol) this was designed in 1982.
