Your domain,
answered.

Forward email from any address on your domain straight to the inbox you already use. ARC sealing and SRS keep DMARC intact across the hop, so it lands in your Gmail, Outlook, or Proton inbox — not spam. Optional AI auto-replies grounded in your own knowledge base.

Quick question — does the free plan include DKIM signing, or do I need to upgrade?
◇ AUTO-REPLY · KB-GROUNDED
Hi Jordan,
DKIM signing kicks in on the Pro plan and above — outbound forwards get signed automatically. The free tier still gets full SPF + DMARC pass-through, just no DKIM signature on the relay.

02Optional AI replies

Drafts in
your voice.

In addition to reliable forwarding, each domain can have its own knowledge base — your FAQs, policies, sample answers — and a persona you define. The assistant retrieves what's relevant and replies. Credit-capped so costs stay predictable.
