Been discussing with Mailgun and it seems the issue isn’t there. Here’s what I’m getting, followed by what I’ve done so far: Error with transactional email when trying to sign-up a test user to the newsletter: POST https://wevchange.org/members/api/send-magic-link/ Response: 500 Internal Server E…

Which API key is this? Would the config override this or are both necessary? [Screenshot 2025-12-18 at 11.58.39 AM]
