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.

02AI Auto-Reply

Drafts in
your voice.

Each domain gets 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 a runaway thread can't run up the bill.
