Thanks, @sharonlicari!
Hi @MichaelWallis1 ,
From my experience, daily would be the same in both scenarios. Instant is only an option for a HubSpot blog not an external blog - I assume because the system has immediate access to publish data.
Another consideration is that with the instant option you don’t have the ability to display more than the most recent published article.
I like daily, weekly and monthly based on subscription preference because they are more predictable in your audience’s inbox. AND for weekly and monthly you can include the top x number of recent posts as an ICYMI round up.
Hope this helps sort things out!
Best,
Diana
