Max Stack Now
If you missed Hyperise, max stack Nexweave now because not only do they have a solid tool, ever increasing growth in the space, and features not available in most marketing apps, but the competition is breeding innovation which is great for users.
Nexweave brings a lot to the table and the limits are pretty generous if you take into consideration that the limits are based on actual generated images/videos that are opened. If you send 100,000 emails with a Nexweave enrichment and only 1,000 open them, then that 1,000 opened emails reach the credit limit for the first stack, not the 99,000 unopened links. Knowing that eases things a lot!
Pros: Works very well and within many different use cases from small custom headers to large photo formats full of dynamic text.
Cons: The UI is a bit clunky and the images seem to be compressed too much for my liking as I am a pixel-peeping A/V Sumo Master.
