Yes, continue to seed as you normally would. Filtering takes place at the gateway, before VTO happens in the inbox. So if your emails are immediately getting blocked or going to the spam folder, CoreSeeds will show you that information. You’ll also get SmartSeeds engagement data by seeding.
Because VTO holds email until the subscriber is active in the inbox, in some circumstances, a VTO campaign may show up under Missing rather than Inbox or Spam, so keep that in mind when reviewing your results.
