CadenceRelay is a bulk email app for sending large campaigns from your own setup. It works with Gmail SMTP or AWS SES. You can send personal emails at scale, track opens and clicks, and watch results in one place.
It is built for people who want a simple way to manage email sends without using a paid email tool. You can run it on Windows, keep your lists in order, and use built-in controls that help spread out sends and reduce the chance of delivery issues.

- A Windows PC

- A Gmail or AWS SES account if you want to send email

You can check:
