2. It’s an email hash. What it is all
about?
 Fluttering in the market space for a
while, a topic that has been
dominating is the “hash of the email
address.” But for now, it has been a
one-sided discussion. While most of
the people are somewhat technically
oriented, most of them are business
people focused on the sales and not
technical side of their enterprise.

3. So what’s an MD5 Hash?
 An MD5 hash is a “cryptographic
function” that takes an arbitrary piece of
data, like any email address and
converts it to a 32 character
hexadecimal string. Every time you run
the same piece of data through the
hashing algorithm you get the same
result.

4. “Hashing” an email address is a
very simple process.
 An email address like dave@liveintent.com
 An MD5 hash algorithm application – there
are dozens of free apps for this, just search
for “MD5 hash programs”
 Run the email address through the MD5
algorithm
 Out pops a one-way, unique value (in this
case: robert@liveintent.com converts to
43307bb5a669b247270a4d81cce6f3ff)

5. Email Hash – The
Implications
 Dedicated email campaigns
Advertisers can send over a “hold out list” consisting
of MD5 hashes, match them to the publisher’s file
and suppress the matching results.
 Custom audience campaigns
All of these custom audience campaigns of social
media sites are dependent upon email hashes or
hashed phone numbers for their targeting.
 Email ad exchanges
Thousands of newsletters from hundreds of top
publishers now feature “email addressable audience”
via hash based targeting. Targeting only the hashes
reduces waste and increases response rate.
