Wren

Wren is a free web tool that writes and designs internal team emails from a single sentence. You type a messy brief like 'Stefan joins as CSM next Monday,' and Wren turns it into a polished email with real serif typography, your brand color, and a clean layout — ready to paste into Gmail or Outlook in under a minute. It handles new hire announcements, office notices, policy updates, and any other internal message you'd normally write from scratch.

The process is simple: describe your email in one or two sentences, let Wren design it with proper formatting and your brand color, then copy the styled HTML and paste it directly into your usual email client. Fonts, colors, and buttons survive the transfer. Wren offers three pricing tiers: a free plan with unlimited emails and 25 AI-written drafts per month (includes a 'Made with Wren' footer), a $9 one-time credit pack that removes the footer for 15 emails, and a $39/month Pro plan with unlimited footer-free emails, saved brand kits, and templates.

Wren is best for team leads, managers, and HR professionals who send regular internal updates but don't have design skills or time to format emails. It's also useful for anyone who wants their team communications to look professional without learning HTML or email design tools. The free tier is generous enough for occasional use, and the credit pack lets you send important announcements without a subscription.
