Tools / Amazon SES / Amazon SES vs Plunk
Email at scale for nearly free.
Amazon SES (Simple Email Service) is Amazon Web Services' email sending service — the page title calls it a "Cloud Email Sending Service." This directory files it under transactional email. Unlike standalone email tools, it's an AWS product: you use it through an AWS account, and it sits alongside your other AWS services rather than being a separate vendor. That makes it a natural option if you're already building on AWS and want email as part of your existing infrastructure. One honesty note from our scrape: the SES homepage is almost entirely AWS site navigation and cookie-consent text, so pricing, feature specifics, and integration details aren't visible here. AWS's own pricing page and documentation are the place to verify those. The tagline's "nearly free" is the listing's claim about cost — we can't confirm exact rates from the homepage.
Open-source email on top of AWS SES.
Plunk is an open-source email tool that sends through Amazon SES. It covers both of its listed categories: transactional email (receipts, notifications, confirmations) and marketing email (campaigns, newsletters). The defining detail is the architecture — rather than operating its own mail infrastructure, Plunk sends through SES, so anything you send rides on Amazon's email system, with its sending limits and pricing underneath. Because the project is open-source, the code is publicly available to inspect and self-host. Details like whether a hosted version is offered, current pricing, and the full feature list aren't covered in this listing — useplunk.com is the source of truth for those.
