Hello, I was considering your full tier and was wondering if this software will achieve my planned use case? Here's the flow of what I am trying to do for a new newsletter:

1. Gumroad - Lead generation, and all of the emails will be automatically sent to Enginemailer.
2. Blog Post - I have a blog post that has lead generation to enter their email and wanted to send it to Enginemailer automatically.
3. Social Media Post - Where there's a link for them to be on my landing page and prospects will enter their emails and again send them automatically to Enginemailer.
4. Quiz Builder - Any leads gathered on my quiz builder will also be sent to Enginemailer automatically.

Would these be possible? I am not familiar with your API as I am non-tech, and do you provide any assistance if needed?
