How can I forward email from a workflow with an email trigger?

I have a somewhat esoteric problem. I receive one email per day that I want to forward to another address, but I want to modify the body first, and keep the From address the same. Pipedream looks like a really convenient way to run code on received emails, but it’s built-in mechanism for sending emails provides no control over the destination and rewrites the From. I see actions available for sending mail via external services like Amazon SES, but I don’t want to deal with potentially incurring fees with external services (Amazon SES has a free plan but it says there are data transfer fees, and I don’t want to deal with payment information to pay them $0.03 per month).

Does anyone have any suggestions for the simplest way to forward email to another address? Is there any way to avoid a dependency on an external service? If not, is there a recommended service that’s easy to use, provides a sufficient free tier, and doesn’t require a credit card to use it?

What I ended up doing last night was using a code step to run Nodemailer to send via my Fastmail account. But that’s awkward and doesn’t act like a true email forward (I’m manually preserving the Date and Message-ID headers, but nothing else, and if I did want to try and preserve all headers, it wouldn’t be attaching the new headers that are intended to be provided when forwarding messages). Thankfully for my particular use-case that doesn’t really matter, but I wish there was an easier way to do this.
