I built a great email output using a file called Email04 and when I was working on the last field, the screen went blank and all my work was gone.
So I have started again and now it won't operate. I am trying to start up again with just one variable "ToEmailAddress" and it won't run.
I am attaching the entry form. Any thoughts?

Summary
A Retool Cloud workflow built to send an email (originally 'Email04') lost all its work when the editor screen went blank, and now a fresh rebuild with a single 'ToEmailAddress' variable won't run at all.
AI Response
A 'won't run' / 'Workflow failed to run' error most often means the workflow has no valid startTrigger block, so the run has no entry point — confirm the startTrigger exists and use it (or the block's 'Run' button) to execute. To rebuild the email flow reliably, follow the official Workflows tutorial, which walks through wiring a startTrigger to a Retool Email block on Cloud and running it end to end. Note that Retool Email applies a rate limit (120 emails/hour), which is worth keeping in mind once the flow is running. Saving/publishing frequently helps guard against losing in-progress edits.

Hi @mdsmith1,
I went through the issue on my end and tested it using only the ToEmailAddress variable. It is working correctly for me.
I’ve attached a few reference screenshots below showing the configuration and successful execution.
If you’re still experiencing the issue, please share the current error message or a screenshot of the error. I can take a closer look and help you troubleshoot it.
Hope this helps!
