Your newsletter,
your infrastructure
Hosted subscribe pages, embeddable signup widgets, public archive — all running on the same Posthawk sending setup you already trust for transactional email. Self-host or run on the managed cloud.
Same DKIM. Same SES.
Same deliverability.
Newsletters share the workspace your transactional email already runs on — same domain, same DKIM key, same suppression list, same warm reputation. No second sender to set up, no second IP to warm.
- Hosted /n/yourname subscribe page
- Embeddable subscribe iframe
- Double opt-in confirmation flow
- Public web archive of past issues
- Honeypot + abuse protection
- React Email issue templates
- Open & click analytics per issue
- Cascading unsubscribe (newsletter ↔ contacts)
Ship an issue,
not a platform
Create a newsletter
Name it, pick a slug, add your logo and description. Posthawk spins up a public subscribe page at posthawk.dev/n/yourname instantly.
Share your page
Send readers to your subscribe page or drop the embeddable subscribe widget into your own site. Subscribers sign up with just an email.
Confirm and protect
Double opt-in by default. Honeypot, IP and email throttling, MX + disposable-domain checks, suppression list — all on automatically.
Write and send
Compose issues in React Email — the same templating you use for transactional. Preview it, send it, watch opens and clicks land in the dashboard.
Self-Hostable
Run the whole stack on your own servers and your own domain. Posthawk is open source — pull the Docker images, point your DNS, ship. No Posthawk subdomain, no usage limits, your data stays yours.
Subscriber Protection
Honeypot, IP and per-email throttling, suppression list, MX + disposable-domain checks, and optional built-in email validation — all on by default. Bombing attacks and typo'd addresses never reach your bounce rate.
Public Archive
Every issue is also a public web page — good for SEO and sharing. Paid issues show a preview with an upgrade CTA.
Embeddable Widget
Drop the subscribe form directly into your own site as an iframe — your styling, your domain. Sign-ups land in the same Posthawk subscriber list as the hosted page.
React Email Templates
Your newsletter uses the same template system as your transactional emails. Consistent branding, zero duplication.
Built-in Analytics
Open rate, click rate, subscriber growth, and bounce/complaint signals — all in the Posthawk dashboard. Per-issue breakdowns, no third-party tracker pixels.
Start building your list
The footer signup already captures newsletter subscribers into your Contacts — tagged and ready to reach via Broadcasts.
