    General guidance from repository metadata, not legal advice. How we score

    From the README

    The Open Source sending infrastructure.

    As most of email products out there, Unsend also uses Amazon SES under the hood to send emails. We provide an open and alternative way to send emails reliably and cheaply with a great dashboard. You can also use Unsend manage contacts and send bulk emails(newsletter, product updates etc). We will take care of the subscriptions.

    Currently we only support emails, but we plan to expand to other sending protocols like SMS, push notification and even whatsapp.

    We are currently in beta and trying to rollout to public slowly. If you're interested join our waitlist or drop in a message in discord.
