Background: I have a daily batch process that creates a sendable Data Extension from a query on a Synchronized Data Extension. The automation runs a query that overwrites the sendable Data Extension each day that it runs, sends to that DE, and then another query appends that day's information to a historical Data Extension.
Problem: We have received some complaints that the View As Web Page link is broken on this email. We figured out that this is because the sendable DE overwrites each day, so when the overwrite occurs the VAWP link is unable to lookup to the sendable DE to recreate the email.
Solution: Create a historical DE with the first query by querying for that days information and appending it. Create a filtered data extension that includes everything prior to today. Send to the historical DE and suppress the filtered DE, which in effect would send only to today's data.
Question: Will using a Suppression list increase send time? If the Historical DE is 400k records and the filtered DE is 390K records, will sending to 10K records in that manner taking longer than just sending to 10K records without the suppression?
