What you get for $149 once
- Lists & subscribers. CSV import with dedupe and invalid-email reporting, public signup endpoint per list, CSV export, full status tracking (pending → subscribed → unsubscribed/bounced/complained).
- Double opt-in by default. Signup → signed confirmation link; only confirmed subscribers get campaigns. Consent timestamp + IP stored for GDPR.
- Segments. Saved AND/OR filters — domain, name, custom fields, signup date, opened/clicked recent campaigns — with a live count while you edit.
- Drag-block builder. Heading, rich text, image, bulletproof button, columns, footer. Compiles to table-based inline-styled HTML — no flexbox, no grid, no Outlook surprises.
- Throttled sending, any SMTP. Default 30 msgs/min (configurable) over pooled nodemailer. Pause or cancel mid-send; the queue lives in SQLite, so a restart resumes where it left off.
- No renewal, ever. The license does not expire and there is no per-seat meter — $149 is the whole price.
Pricing questions
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/postbird-mvp, always. $149 buys the packaged installer, 1-click setup and updates — and funds the open-source version.
Will my emails land in the inbox?
Deliverability is your SMTP provider's job, and Postbird is honest about that: use SES or Postmark credentials and you inherit their IP reputation. Mailchimp's managed sending infrastructure is genuinely convenient if you'd rather not think about SPF/DKIM at all — that's what the monthly fee buys.
Is it actually CAN-SPAM / GDPR compliant?
The legal minimums are enforced in code, not suggested: the server returns a 400 if you try to send without a physical address configured, the compiler appends an unsubscribe footer if a template lacks one, and every email carries RFC 8058 one-click unsubscribe headers — which Gmail and Yahoo require for bulk senders.
Does it do automations and A/B tests?
No — drip automations and A/B testing are deliberately out of scope for now. Postbird covers lists, segments, campaigns and tracking. If your marketing lives on complex journey builders, Mailchimp still wins there.
