Newsletter subscription discount code not received

I have a USB-C to 3.5mm jack adaptor in my basket and I want to use a €5 discount code towards it.
Although I signed up to the FP newsletter, the code wasn’t mentioned in my confirmation email.
Even more frustrating, I’ve tried twice to screenshot the Google search result page which mentions this newsletter code, and they’ve both disappeared so I have no proof it exists.
Please advise.
