The deliverability-data and DNS-write integrations were over-engineered
for the cold-email segment. Postmaster and SNDS require sending volume
our base typically does not hit, and no comparable cold-email tool
exposes DMARC ingestion or native DNS writes. Replaces the catalog with
the standard set: HubSpot, Salesforce, Pipedrive, Close, Zapier, Make,
n8n, Slack, Discord, Calendly, Cal.com, Google Sheets.
Removes dmarc_reports, dmarc_record_rows, postmaster_snapshots, and
dns_verifications tables from the migration. Deletes dmarc.go, dns.go,
cloudflare.go, postmaster.go from the integration package. Prunes the
matching repository methods and HTTP handlers.
Adds an integrations app module covering the providers from the tier 1/2
plan: Calendly, Cal.com, Google Sheets, Google Postmaster, Microsoft SNDS,
DMARC ingestion, and Cloudflare/GoDaddy/Namecheap DNS. One unified
migration provisions integration_connections, dmarc_reports + record
rows, postmaster_snapshots, dns_verifications, and meeting_bookings.
The service exposes a generic CRUD surface for connection state with
per-provider files for parsing (calendly.go, dmarc.go), HTTP clients
(cloudflare.go, postmaster.go, google_sheets.go), and DNS verification
(dns.go). Inbound webhook routes use per-org URL-embedded secrets so
Calendly/Cal.com/DMARC providers post directly without Warmbly auth.
DNS verifier resolves SPF/DKIM/DMARC + tracking CNAME and surfaces
fixes when a record is missing.
