Resize image attachments

I can not believe an email program as good as this does NOT have the functionality to resize image ATTACHMENTS. I know it does it for inline/inserted images, so please do not respond with “how to for inline”. Is there any add-on/workarounds.
I would consider paying for the pro version, but not without this feature.

I assume you mean resizing an attachment after it has been attached to the outgoing email.

You can - or at least I can. In Win 10, set you default image editor to IrfanView and you can edit, resize attachments at leisure.

I’ve tried it with the latest version of eM Client and it worked fine for me.

nb Other image editors (like Paint) may throw a sharing violation error.
