@SalamaErgossum

Just ran my first automation workflow with @relay !

I wanted to send newsletters from Outlook to Notion, and it was so easy I almost cried—after struggling and giving up with other tools like Make.

Huge thanks to @relay for empowering non-tech folks like me!

Relay is a fantastic app. I keep finding new uses for it everyday. I am not a programmer but I can make some really complicated work flows work pretty quickly.

I truly appreciate how @relay presents testing info. You can easily see what you are testing, and the messages are very clear if there's an error.

They are definitely creating a fantastic tool!

Relay's "human in the loop" model is super effective for teams. Not only is this the best designed UI for automation building on the market, they've really thought about how not everything can be automated. Fantastic for building operationalized SOPs.
