About Plunk

Plunk brings transactional email, broadcasts and event-based automations into one product. A software maker can connect a verified sending domain, create a template for a welcome email and send it through the API when a customer creates an account. The same contact data can support a later product announcement or a sequence based on an event you send. Test event names and template variables against a staging workflow so errors show up before customers receive email. The documentation describes both hosted use and self-hosting. Choose based on whether operating the mail stack is part of your team's work. Plunk is especially relevant when product events and marketing messages should share context. A simple newsletter sender may be enough if all your messages come from an editorial calendar.
