I’ve sent e-mails to support (and sales) but had no response (I’ve checked spam). Issue is this:

I’m using the send email action in FB (using latest .3564) which works great, but I wanted to send a html version, and I’ve made some with an online service called stripo, and they send just great with my Delphi software so I thought I’d try one with Finalbuilder to notify users of a release, which look a bit nicer than my current plain text ones.

Attached is a small sample with little in it but it shows the error I am getting and I wonder if maybe it should work or can you suggest something to make it work?

This is where I have pasted the contents of the html:

![Screenshot 2026-05-14 at 09.19.40.png]()

The error is:  
Unable to Set Body  
[Expression Error]: Variable\Object " " does not exist! [yle\>sup { font-size: 100%‸ !important; }\<![]

Ideally, I’d like to be able to change some of the text with a variable prior to sending, but that’s not too important.

Hi Jeremy

I can’t see any recent emails in our sales/support system.

The issue you are seeing is because the action is attempting to expand any variable references in the body. So any `%` characters need to be escaped so that they are not seen as the start of a variable reference , e.g

`font-size: 100%%`

1st time to support was 14th May, then to both on 24th June (every time I do a build I remembered!)

Anyway, thanks, quick replace all % to %% and it works great.
