fix(sales): diagnose inbound-only mail path behind blocked sender trust - #102
Conversation
send:setup now resolves MX records and flags Cloudflare Email Routing as inbound-only, so the DKIM warning points at the real first step (connect an outbound provider) instead of implying a selector exists to find. The sender-setup guide's fix order leads with the provider step. Physical postal address and dkimSelector stay empty: no real address is published for this business and no DKIM records exist in DNS, so neither value may be invented.
The active-operator surface gate regenerates the tracked sender/market docs with a fixed clock and byte-compares them. Regenerate through that exact path so the 11/10 proof-run brief, parity readiness, benchmark, matrix, and guide carry the new inbound-only mail path evidence with the canonical generated date.

MX records describe where inbound mail is received, not how the domain sends mail. A valid setup using Cloudflare Email Routing for inbound mail and Resend/Postmark/SendGrid for outbound will continue to show this check as missing, while a domain with non-Cloudflare MX records but no outbound provider is reported as found. This makes the new diagnosis unreliable in both directions; derive outbound readiness from an explicitly configured sending provider and its authentication instead.

When DNS is temporarily unavailable or returns SERVFAIL/ETIMEOUT, this catch converts the resolver failure into an empty result, and the caller consequently states that no MX records exist and replies will bounce. Running send:setup or regenerating tracked operator artifacts during a transient resolver failure therefore produces a false configuration diagnosis and potentially instructs the operator to change valid DNS; preserve the error so lookup failure can be reported separately or retried.

When the configured sender has a postal address and DKIM selector but genuinely has no MX records, this branch makes send:setup warn that replies will bounce, but sendChannelGuidance() still computes emailReady solely from those local config values. Consequently, checked consumers such as update-prospect-pipeline.mjs, complete-prospect-batch-send.mjs, and the prospect outbox permit and recommend email despite this new failure; propagate the setup failure into the shared email-readiness gate so operators cannot proceed with a reply address known to reject mail.

When the operator chooses Outlook/Microsoft 365—one of the providers recommended by this change—the provider supplies selector1 and selector2 CNAME records rather than a DKIM TXT record. This unconditional instruction can therefore make the operator create the wrong DNS record type, preventing provider verification and leaving DKIM blocked; instruct them to publish the exact record type and values supplied by the provider, as the previous conditional wording did.

When a sender domain has no MX record but its A/AAAA address accepts SMTP, standard mail routing treats that address as an implicit MX target. This branch instead states that replies will bounce and marks setup as failed, so a valid receiving configuration is misdiagnosed; verify the implicit host before emitting the no-reply-path warning.

When a domain publishes a null MX record (0 .) to declare that it accepts no mail, mx.length is nonzero and the root exchange does not match the Cloudflare pattern, so this records the path as found. Such a sender cannot receive replies and may let send:setup pass once the other checks are satisfied; detect the null-MX sentinel and report it as unavailable.

When send:configure -- --sender-email=... switches to a domain that uses another mail host—or when an outbound provider is already configured—send:guide still claims Cloudflare Email Routing is in use and instructs the operator to connect a provider, even if the setup checks pass. Derive this fix-order step from the actual inbound-only warning/check instead of emitting it unconditionally; the HTML instructions have the same issue.

The outbound mail path still routes through Cloudflare Email Routing, which forwards inbound mail only and blocks cold email until sender trust is clean. PR #102 already diagnosed the inbound-only mail path and explained that the physical address and DKIM selector cannot be invented when no business address is published and no DKIM records exist in DNS. DNS now exposes a real DKIM record at resend._domainkey.tinystudio.io (`p=` RSA key published by Resend), so the sender trust check can be populated from the live selector instead of guessing. Save dkimSelector as `resend` in agency-config.json and widen the discovery list to cover the modern outbound providers a founder-led studio is most likely to use (Resend, Postmark, Mailgun, Amazon SES, Mailjet, Brevo, SparkPost, Klaviyo, HubSpot, Mailchimp, Elastic Email, MailerSend, Fastmail, Tutanota). The selector list still does not invent values; it only lets the check discover a real selector the provider has already published. After this change: - DKIM: ready (resend._domainkey.tinystudio.io) - Sender trust warnings drop from three rules to one: the postal address. - export-sender-setup-guide now reports the actual configured selector (or a discovered candidate) in the dry-run command and adapts the fix-order steps to the current state, so the guide stops telling the operator to enable DKIM that is already enabled. - The four tracked operator artifacts that read the sender setup state (11-10-proof-run, market-parity-readiness, competitive-proof-matrix, market-parity-benchmark-2026) and the sender-setup-guide markdown and HTML are regenerated through the same fixed-clock path the active operator surface gate uses, so the byte-identical check stays green and the operator sees the actual sender trust state. senderPhysicalAddress stays empty: no physical address is published on tinystudio.in or any privacy/terms/contact surface, so the value cannot be invented. The remaining sender warning points at that single blocker. Co-authored-by: Nish <nish3451@users.noreply.github.com>

What
npm run send:setupstayed blocked on two empty config values —senderPhysicalAddressanddkimSelectoringrowth-brain/ops/agency-config.json—with no diagnosis of why they are empty. This PR makes the block precise and
actionable; it does not invent either value.
Root cause (verified, not guessed)
site explicitly publishes "No base city or office address is stated", whois is
privacy-redacted, and no address exists in the repo. CAN-SPAM requires a real
address in commercial mail; fabricating one would put a false compliance footer
(
appendEmailComplianceFooter) into real emails.common selectors). MX is
route*.mx.cloudflare.net— Cloudflare Email Routing,which is inbound-only and cannot send outbound mail. No outbound provider
is wired into this repo, so no selector exists to discover.
Both values are real-world facts only the operator can supply.
What changed
scripts/check-outbound-sender-setup.mjsnow resolves MX records and emits anOutbound mail path check. When MX is Cloudflare Email Routing (and no DKIM
selector is configured), it warns
outbound mail path is inbound-onlywith theexact unblock sequence: connect a sending provider (Google Workspace, Zoho
Mail, Outlook, Resend, Postmark, SendGrid), enable DKIM there, save the exact
selector. No-MX domains get a bounce warning.
scripts/export-sender-setup-guide.mjsFix Order now leads with the providerstep instead of implying a selector exists to find.
surface-gate path (byte-identical to
test-active-operator-surfaces.mjs),so
send:setup, the guide, the 11/10 proof-run brief, market parityreadiness, competitive matrix, and benchmark all carry the new evidence.
Verification
npm run send:setupnow shows SPF found, DMARC found, outbound mail pathmissing (inbound-only), DKIM discovery missing — with precise guidance.
npm run cipasses end-to-end (exit 0), including the active-operatorsurfaces byte-gate.
Operator next step (Nish)
private mailbox) →
send:configure -- --physical-address="..." --dry-run.record at
<selector>._domainkey.tinystudio.ioin Cloudflare DNS →send:configure -- --dkim-selector=... --dry-run, then apply.Until then the block is intentional and correct: contact forms/DMs remain the
recommended channel.
