NOTE: This article references "informz" -- a previous name of the Higher Logic Informz product.
A synchronization ("sync") brings new email addresses into Informz from iMIS, updates existing addresses, and updates other information from iMIS.
A sync uses the Informz_Changes table in iMIS (created by Informz as part of the integration) to determine which email addresses are new, which have been removed, and which have changed. Informz only syncs iMIS records that have statuses that Informz is set to accept (e.g., Active), that have an iMIS ID, that have valid email addresses, and that are not unsubscribed or opted-out.
Informz syncs on Name.Email or Name_Address.Email+Purpose and Preferred status from iMIS.
There are four instances when Informz syncs with iMIS:
- Manual sync – A manual sync is initiated by a user (you or another admin from your organization). This type of sync looks at the Informz_Changes tables for additions and changes. To perform a manual sync, navigate to Contacts > Upload > Sync with iMIS.
- Sending a message – Each time a message is published, Informz syncs with iMIS. During this process, Informz queries iMIS and retrieves any new contacts that match the criteria of that target group.
- Nightly sync – This is an automated process that runs every night. It syncs iMIS IQA groups that have been created in the past seven days, or that were used in a message in the last 90 days. This sync also sends writebacks to iMIS for iUnsub, iOptout, iCorrect, iResub, and iBadEmail. All writeback data is placed in the iMIS Activity table.
- Weekend sync – This is an automated process that Informz runs each Sunday morning; it is a full sync on all iMIS target groups.
- Partial Sync - A partial sync (also called a partial refresh) brings over new and changed data (such as a change of email address or a new iMIS ID) from iMIS to Informz. Informz automatically syncs with iMIS every time a message is sent. A message sync brings in any new contacts and the most current email addresses from iMIS.
- Full Sync - A full sync (also called a full refresh) is the same as the weekend sync in that it removes all records in the Informz_Changes table and rebuilds that table based upon the selected preferred status values used to sync. This is a useful way to exercise all of the database triggers used in the integration.
NOTE: The Partial Sync does not do the “remove all records” step. A Full Sync is manual and can only be executed by Higher Logic staff.
Post-sync target group counts
There are times when the number of records returned after a sync don't match your expectations. Here are some likely reasons:
- Some iMIS records do not have valid email addresses
- Some iMIS records do not have preferred statuses (i.e., Active)
- Some email addresses may have been previously unsubscribed in Informz
If you believe counts or other iMIS information you are seeing is incorrect or outdated, create a case.
In addition to one of the sync methods mentioned above, contacts can be brought into Informz by uploading a list of contacts (navigate to Contacts > Upload > Contacts).
NOTE: If a contact email address is directly uploaded into Informz, its record will NOT have an iMIS ID until it is subsequently brought in by a sync with iMIS. When this sync with iMIS happens, the existing contact record in Informz will be updated with the iMIS ID and all of the contact’s message history. This prevents duplicate records from being created in Informz.
