Sendune is an open-source HTML email designer with an AWS SES dashboard for teams that send transactional and marketing email through their own AWS account. Its MIT-licensed drag-and-drop designer builds templates that work with any email provider, while the hosted dashboard manages contacts, campaigns, and delivery statistics.[1][2][3]
Quick verdict
Teams already sending through AWS SES benefit most from Sendune. One MIT-licensed designer covers drag-and-drop, HTML, and plain-text templates with portable pure-HTML output, and the dashboard adds tag-based contacts, API and workflow sending, and delivery statistics. The constraint is operational: your own AWS account, one of three regions, and SES sandbox exit are mandatory. Teams that can carry that should default to Sendune; teams wanting zero operations should compare hosted providers, and minimal-setup self-hosters should compare Listmonk first.[1][2][3][4]
Key features
Drag-and-drop designer Drag-and-drop designer: compose professional emails with a minimal no-code interface designed to stay out of the way.[1][2]
Three template modes Three template modes: build with drag-and-drop, reuse or hand-write HTML in the code editor, or send plain-text emails.[1][2]
Pure HTML output Pure HTML output: templates compile to plain HTML with no mjml-style intermediate layer, and saved HTML works with any email service provider.[1][2]
npm Angular library npm Angular library: install @send-with-ses/ng-email-designer, import the module, and theme it with documented CSS variables; image storage plugs into S3, R2, or any cloud store you choose.[1][2]
Tag-based contacts Tag-based contacts: store contacts through the Contacts API, attach tags such as wishlist items, and slice the list to send targeted messages.[1][2]
Manual, API, and workflow sending Manual, API, and workflow sending: dispatch from the dashboard, from your code, or from trigger and if-this-then-that automation rules.[1][2]
Delivery statistics Delivery statistics: campaign-wise tracking of delivery, opens, and clicks, with bounces, complaints, and unsubscribes handled out of the box.[1][2]
Deliverability guardrails Deliverability guardrails: SPF, DMARC, and DKIM setup support plus InboxVISA checks that steer genuine senders away from honest mistakes.[1]
Who will love it
SES cost savers: teams already on AWS that want SES per-email rates behind a no-code dashboard instead of per-contact SaaS pricing.[1][2]
Angular teams needing an embeddable editor: the MIT library drops into an existing app with theming variables and operator-owned image handling.[1][2]
Portability seekers: pure-HTML output with no lock-in suits teams that design once and send through more than one provider.[1][2]
Who should avoid it
Teams without AWS skills: an IAM role with broad access, a fixed region choice, and moving SES out of the sandbox are mandatory, and the setup guide assumes comfort with the AWS console.[1]
Teams outside the three supported regions: sending runs only from US East (N. Virginia), US West (Oregon), or EU (Ireland), so data-residency needs elsewhere are not covered.[1]
Teams needing documented SSO or enterprise support: I found neither on the inspected site, docs, or repository pages, so regulated buyers should treat both as unavailable until the vendor says otherwise.[1][2]
Alternatives and compatibility
Sendune is the natural catalogue comparison to Listmonk: both run campaigns on infrastructure the operator controls, while Sendune pairs its editor with AWS SES and Listmonk pairs its own editor with any SMTP or provider.[1][2][3]
Sendune fits teams that want the editor itself: the standalone MIT Angular library embeds in any app, which campaign-only platforms do not offer.[1][2]
Hosted Mailchimp-style providers fit teams that want zero AWS operations: Sendune trades their per-contact fees for IAM roles, region choices, and reputation management you own.[1][2]
Questions worth asking
Is the Sendune email designer really free and open source?
Yes. The designer source is published under the MIT License, copyright 2023 Send With SES, and the docs say it can be used for personal or commercial use. A live demo runs at designer.sendune.com, and the library installs from npm. The hosted SENDUNE dashboard around it is a separate freemium service, as checked October 12, 2026.[1][2][3]
Do I need my own AWS account to use Sendune?
Yes. SENDUNE integrates with your own AWS account: SES sends the emails, SNS and CloudWatch feed delivery statistics, and S3 stores template images. Setup picks a primary contact key, one of three AWS regions (US East N. Virginia, US West Oregon, EU Ireland), and an IAM role, then you move SES out of the sandbox through AWS support.[1][2]
What does Sendune cost?
The dashboard has a free plan with 1,000 contacts and 3,000 emails and no credit card required. Pay-as-you-send costs $10 per month plus $0.0001 per email with unlimited contacts under fair use. AWS bills its own SES usage separately on your AWS bill, and all prices exclude taxes.[1]
