Free & OSS SMTP Bulk Cold Email Sending
cold0 - bring your own SMTP cold email sending and managing
What it does
Have you ever wanted an app that just lets you: - connect your own email domain - import your contacts from CSV - create a simple template - bulk send and keep track of sent emails You find something similar, but you need to pay to be able to use it via SMTP? I created this FREE and open source app that lets you do just that! Currently there's a demo deployed on Vercel. The app is still very fresh and I am looking for fellow engineers to join and help me create a commercial version of app!
