I also think Digesto is great.
There's also building your own using Velocity (blog entry coming soon).
Hi Sanford Whiteman, did you end up creating a blog about doing this with Velocity? I'd love to learn more about that.
I didn't -- though did talk about it at one of my recent MUG talks. Maybe someday. So many drafts. I know I always say that but I have 32 open tabs right now w/blog drafts!
We're using the RSS-2-Marketo tool from overstack.io
It's very customizable - we can keep using our existing Marketo templates. Their connector just updates the program tokens on a weekly basis and triggers the send flow. And the team really helped us with the special customization we needed.
