MailPaw

MailPaw is a free, privacy-first email template builder for newsletters, campaigns, announcements, outreach, and polished everyday emails. It runs as a standalone web app, stores templates locally in your browser, and gives you copy-ready email content plus downloadable backup files.

Free Email Template Builder

MailPaw helps you create reusable email templates without signing up for a hosted email marketing platform. It is built for people who want a lightweight alternative to tools like Mailchimp, Constant Contact, Beehiiv, ConvertKit, Substack editors, and other campaign builders when they only need to design and reuse good-looking email HTML.

Use MailPaw to build:

• newsletter templates
• product launch emails
• event announcements
• customer updates
• founder notes
• community emails
• sales outreach
• onboarding emails
• promotions and coupons
• internal team updates

Privacy-First Local Storage

MailPaw stores your template library in your own browser on your own computer. Your email drafts, saved templates, styling choices, and reusable blocks are not uploaded to a MailPaw cloud account.

Because browser storage is local, download backup copies of important templates. Backups make it easy to restore your library later or move it to another browser.

Features

• Drag-and-drop email template builder
• Reusable blocks for headings, text, buttons, images, dividers, spacers, social links, columns, and raw HTML
• Local template library
• Reusable templates for newsletters, announcements, updates, and outreach
• Copy Email action that pastes formatted email content into clients that accept rich paste
• JSON export and import for local backups
• No account
• No subscription
• No analytics
• No ads
• No tracking
• No cloud template library

How It Works

1. Open the app in your browser.
2. Pick a starter template or create a new one.
3. Edit the blocks, colors, text, links, and layout.
4. Save templates locally for reuse.
5. Copy the email into an email client that supports formatted paste.
6. Download backup copies so you do not lose your work.

MailPaw is a standalone web app. It cannot automatically insert into every mail client. Different email clients handle pasted HTML differently, so always send yourself a test email before sending a real campaign.

Run Locally

npm install
npm test
python3 -m http.server 4173

Then open:

http://localhost:4173/

Why MailPaw Exists

Most email marketing tools are built around lists, campaigns, subscribers, forms, analytics, automations, and paid sending plans. MailPaw is intentionally smaller: it is for designing reusable email templates while keeping the actual template content private and local.

It is useful when you want a clean email layout builder, not another hosted account holding your writing.
