Changelog

What's new in day3.

We're building in the open. Here's everything that's shipped so far.

  1. A public API, cheaper volume, and AI for everyone

    • Manage your audiences from code: a REST API for contacts, custom fields, segments, topics, and suppressions — built so migrating a list off another provider is a short script.
    • The AI writing assistant is now included on every paid plan, starting at $1/mo. Higher plans carry a larger allowance.
    • High-volume plans got cheaper, and the ladder now runs all the way to 1,000,000 emails a month at $220.
    • Deleting your organisation now erases everything it owns — subscribers, campaigns, files, and sending identities — for real.

  2. AI campaign composer, scheduling, and senders

    • Write campaigns faster with an optional AI composer that drafts emails, suggests subject lines, and rewrites copy. It's powered by Claude.
    • Set a monthly AI usage budget per account, so assisted writing never produces a surprise cost.
    • Schedule a campaign to go out later instead of sending the moment you finish.
    • Add multiple sending identities and pick which one a campaign comes from.
    • A refreshed brand, a new marketing site, and an installable app (PWA).

  3. Signup forms

    • Collect subscribers with hosted newsletter signup forms — no site required.
    • Drop a lightweight widget onto your own site for inline or popup forms, or take the raw HTML and style it yourself.

  4. Sending foundations and onboarding

    • A guided onboarding checklist takes you from sign-up to your first campaign, with clear gates before anything sends.
    • Verify your sending domain with automatic DNS setup, so authentication (SPF, DKIM, DMARC) is handled for you.
    • DNS access tokens are stored with versioned, rotating encryption keys.
    • Imports recover cleanly from failed or malformed rows instead of losing the batch.
    • Clearer billing and plan-change behaviour throughout.
