Sending HTML email from IBM

I am looking for a good way to modernize our emails coming from the IBMi.
In the planning now.
Currently they are just simple text emails. We would like to take
advantage of HTML and embedding images etc. I have a POC of RPGMail that
works but know this is outdated and dependent on the version of Java.
One thought I had is to create an email table that has the email
information, Subject, body, address, status, sentDate, etc. and let some
product read this table to send it. We do something like this for our text
messages.

I am looking for recommendations on ways/products to do this. I am sure
that management will say don't spend any money.
TIA.
