Found via live mail.log: Google-Workspace-hosted PRACTICE domains (custom domains whose MX is aspmx.l.google.com, e.g. moosepharmacy.com, hc2kidney.com) were getting hard 550-5.7.1 rejects from Google's cold-IP bulk filter -- exactly the bounces that wreck a warming IP's reputation. The original google/non-google split classified by the email's domain STRING, which can't see that a custom domain silently uses Google Workspace; only an MX lookup reveals it (33% of our domains, 228/689, are Google-hosted this way). - hc_data_refresh.py: new MX classification (one lookup per unique domain via dnspython, cached) writes an mx_provider=google/other flag into the master and propagates it into the channel CSVs (auto-adding the column). --skip-mx for a fast status-only run. - build_healthcare_campaigns_cron.py: warm_segment now drops mx_provider=google rows during warmup (HC_SKIP_GOOGLE=1 default; set 0 once IPs are warm). This is defense-in-depth -- correct regardless of which CSV the cron is pointed at. Verified: today's sends (nongoogle CSV) had 0 Google bounces; the guard cuts the Google-containing week1_verified cohort's revalidation candidates 82->8.

"""Healthcare warmup campaign builder for listmonk-hc.
|
|
|
|
Runs daily (Mon-Fri, 7 AM Central via cron). Each run:
|
|
1. Imports the next slice of the VERIFIED, overdue-first warmup list into a
|
|
listmonk-hc list (deduped; already-imported rows are skipped).
|
|
2. Ensures the teal "Medicare revalidation overdue" campaign exists and is
|
|
running, pointed at that list.
|
|
3. Listmonk-hc's sliding-window rate cap (driven by pw-hc-rampcap) does the
|
|
actual per-hour throttling, so this builder just feeds the queue.
|
|
|
|
WARMUP COHORT: point HC_VERIFIED_CSV at hc_warmup_nongoogle.csv for weeks 1-2.
|
|
Google/Workspace-hosted practice domains (~31%) reject hard from cold IPs
|
|
(550-5.7.1 "unsolicited"), which damages warmup reputation. Send the 501
|
|
non-Google practice domains first; switch to hc_warmup_google.csv (222) once the
|
|
IPs are warm (week 2-3).
|
|
|
|
The daily slice size follows the hc warmup ramp so we never queue more than the
|
|
IPs can safely send while warming. Sends ONLY happen via the hc HOT stream
|
|
(listmonk-hc -> host :2526/2527/2528 -> .107/.108/.109), never the trucking pool.
|
|
|
|
Idempotent: safe to run every weekday. Tracks imported emails in a state file.
|
|
|
|
Usage:
|
|
python3 scripts/build_healthcare_campaigns_cron.py # daily slice
|
|
python3 scripts/build_healthcare_campaigns_cron.py --dry-run
|
|
python3 scripts/build_healthcare_campaigns_cron.py --slice 0 # use ramp default
