send three variable attachments in a "Send Email" node

Hello @vitor_castro5,

and welcome to KNIME Community!

In order to send multiple attachments using flow variable you need to have flow variable of type array/collection. This is a older topic which explains it well and contains a workflow example but should be valid still:

How to send dynamic email attachments?

Hi there, Anyone know how to send out dynamic email attachments? I have automated a report I work on daily; however, this reports has a time stamp as part of the naming convention, as such, I’d need some sort of flow variable to change the changing path of the file. I read on other posts that typing in File:/a would work, I have tried it and I am not seeing it under the Flow Variables option.I am attaching a screenshot of my work flow and what I have done. Thank you all! [KNIME%20Email]

Additionally, if possible, I recommend to save file(s) on a cloud/network drive/SharePoint and then in email instead of sending attachments send link to location where files are. This requires a bit of administration with access rights but it’s worth it if files are big or you are sending this to a lot of people or someone needs this files to kick off another process or they need to come back to these files on a regular basis or something fifth

Br,
