My company provides marketing OFT emails for our clients, who often don’t have their own ESP.
Those clients will send them via Outlook to their entire organization / customers (hundreds to tens of thousands).
We do run our primary marketing campaigns out of a good ESP but it doesn't quite fit this use-case.

The biggest reason OFTs have become so popular is simply because they require no infrastruture. It's easy to use it.

I'm desperately looking a safer alternative.

  1. Has anyone successfully persuaded their organization away from using OFTs?
  2. Does anyone have ideas on simple alternatives?
