Skiff is an interesting product that after a year or so of active development, sold itself to Notion and is shutting down its suite of products - of which the most important and difficult to move, is EMAIL.
My email to support at Skiff on April 12, 2023
"Reassure me. I like Skiff, security devs like Skiff - I want to move some login emails to skiff - But Skiff has been active for a short time. And I ask myself - what is its medium term future?"
Skiff Support reply the same day:
"Thanks for reaching out! We're lucky to have a huge amount of funding, growth, and support, and we have many years of funding and growth for the future."
So what do I take from this - that I was right to be cautious about putting anything but a few eggs in a new basket - that intentions don't prove themselves except over the long term - that life is a contant fork in the road of how to react to changes, both good and not so good.
