How should I format my MD5 data to work in SUPPRESS
Overview
This article explains how your MD5 data should be formatted to work within SUPPRESS.
Imports
Emails are normalized for use within SUPPRESS. This means, if a list of plain text emails are imported, we convert the email to lowercase and remove leading and trailing spaces before converting it to MD5. The resulting MD5 is created and stored as a lowercase 32-character string (e.g. ab12bcbd4bd8e8f9abe8d0).
Exports/Downloads
All MD5 hashes and emails outputted from SUPPRESS will be exported in lowercase.
Mailer Cleanses
If a mailer is going to compute MD5s locally, they need to normalize (lowercase) and remove trailing/leading spaces from their emails prior to computation.
Cleanse via OPTIZMO
If a Mailer chooses to cleanse their data using the SUPPRESS cleansing tool, then they can upload their plain text data in either uppercase or lowercase and we will convert them to lowercase prior to the comparison of the MD5 list.
Cleanse Locally
If the MD5 comparison is performed outside of SUPPRESS then the MD5 needs to be converted to (or done in) lowercase.
