Send transactional emails, run marketing campaigns, and automate workflows with one contact list. Open-source, self-hostable, and costs $0.001 per email with no contact limits.
What we know
- How is Plunk different from other email tools?
- Most platforms do one of transactional sending, marketing campaigns, or automation, requiring teams to run two services side by side. Plunk combines all three against one contact list, triggered from a single API call.
- Can I use Plunk for transactional email?
- Yes. Signup confirmations, password resets, receipts, and any other one-off message go out through the same API and the same verified domains as campaigns.
- Can I send newsletters and broadcasts?
- Yes. Build a campaign against the whole list or any segment, schedule it, and track opens, clicks and bounces per send.
- Which languages and frameworks does Plunk support?
- Anything that can make an HTTP request. There is a REST API, an official Node SDK, and SMTP for clients and frameworks that already speak it, so no runtime is excluded.
- What does Plunk cost?
- Two plans: free covers 1,000 emails a month with Plunk branding; paid is $0.001 per email with no branding and no feature tiers. Contacts are unlimited on both, so storing contacts you never mail costs nothing.
