Unfortunately, I can't help you. I'm not technical enough to think about the problem you are trying to solve in a way that would add real value.
Good luck!
Ah okay, yeah my development roadmap which you asked is a bit technical, so I just listed a few.
My product is similar to MailGun, Sendgrid and Postmark. (Email delivery service)
As an old user of these products, I have some experience in what I would want, and what users would want: affordable, easy UI and high inbox.
Well, I hope you can stil take a look at my website and if you have any feedback, will appreciate it much.
