Hi,
I'm an expert Windows application developer with experience in developing email and email tracking application software for Windows.
Per your requirement for an email open-rate tracking software, I am bidding to develop a complete email sending software where it will insert tracking pixels, send and schedule the emails (via SMTP server), and allow you to track the open rate (via web API).
I estimate the delivery time for the first working version of the database to be 30 days (4 weeks), or less.
Good quality work done. I will also be available on the long term should you need additional modifications or support.
Thanks for considering my bid.
Best wishes,
Steve
