List Format - MD5 vs Plain Text
A Standard List may be stored in either Plain and MD5 (system default), or MD5 Only. In general, if you own the data and have it available internally for upload, plain text is recommended so you may choose either format for distribution to your Mailers.
Standard Lists - When a storage type is set to Plain and MD5, plain text must be uploaded, and SUPPRESS will convert it to MD5 dynamically when the list is downloaded (if the Mailer Access setting is set to MD5). Uploading MD5 records to a Plain and MD5 list will not work, since we cannot reverse the hash to store the plain text version.
Group Lists - These may include both Plain and MD5 and MD5 Only lists, however the grouping will only be able to be downloaded as MD5 by mailers, since the Standard Lists within the grouping are seamlessly combined. The system will not allow for mixing of formats within a single file. If all Standard Lists within the grouping are set to Plain and MD5 storage, then the grouping may be downloaded in either format (Mailer Access settings determine this).
A Linked List (Network accounts only) will utilize whatever setting is in place at the original Advertiser's level, and cannot be altered or added to directly, by the Network.
