Maildeno review
An open-source visual editor for developers who need flexible email template exports.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Maildeno is a drag-and-drop email editor and template renderer for product teams, developers, and organizations that want control over template storage, rendering, and delivery. Designers can arrange rows, columns, and content blocks, while developers can add dynamic merge tags, visibility rules, and portable template output. The editor supports desktop and mobile previews, and templates can be rendered locally or through hosted SDKs before being sent with an existing email service provider.
Its freemium pricing starts with a Free plan at $0 per month, including 500 API requests, 10 API keys, three templates, and eight saved rows or modules. Standard costs $7 per month and adds unlimited API requests, 30 API keys, unlimited templates, and 40 saved rows or modules. Pro costs $12 per month and adds unlimited API keys and saved rows or modules, plus priority support. Enterprise includes unlimited resources, seat-based team members, priority support, and an SLA. All listed plans retain HTML, MJML, and React Email output targets.
Maildeno fits teams working across email platforms, with 14 integrations spanning Klaviyo, Mailchimp, Braze, Salesforce Marketing Cloud, HubSpot, Iterable, SendGrid, Amazon SES, Postmark, Resend, Mailgun, SparkPost, and Brevo. Its MIT-licensed editor and renderer can run without a Maildeno backend, which suits self-hosted deployments and teams integrating rendering into their own systems. Choose it when open-source control and multi-format exports matter more than assisted creation; teams seeking built-in AI features or a simpler hosted-only workflow should look elsewhere.
