A while ago, I built a workflow that reads a set of emails and generates a summary of the most important ones — everything was working fine.
However, about three days ago I noticed that two emails are being sent every time, but with different content.
Here’s the setup: I have a workflow that runs every 30 minutes and generates a summary email.
When I check the execution logs, I can confirm there’s only one execution every 30 minutes, and the output is just one item with a single HTML summary.
For some strange reason, I’m receiving two separate emails, not duplicates — their content is similar but not the same. What’s weird is that n8n only shows one execution, yet two different emails are sent out.
**I’m attaching screenshots and logs as evidence.
Last execution**
Items sent in last execution (1 item only): I’ve been testing using the “pruebas 2” node, but as you can see, the node is deactivated — so it can’t be the reason why I’m receiving 2 emails instead of 1.
Even if the deactivation somehow failed, the email content should be exactly the same, not different.
Received output:
Content from email received at 6:30 AM:
Content from email received at 6:31 AM:
Email sent by n8n workflow: which corresponds to the email received at 6:31 AM
Content in both mails are different (but the main context is the same).
Any ideas why my workflow is generating double mails but only shows one execution with one item?
