I would try to reach back to them for help positioning you in a (well earning) junior or mid-level position.
Companies also want that, honestly. Hiring juniors and mid-level is a pain in the ass too.
Someone with a lot of field experience but willingness to learn would be a good fit in lots of companies.
Also lots of companies need people to working with marketing. For this case your skills are far from outdated.
