What you get for $19

Full day-by-day checklist (Days 0–7): Cloudflare baseline → Migadu DNS → IMAP/SMTP proof → Gumroad seller mail hygiene → warm sends → limits → retrospect
Cloudflare MX/TXT expectations and “one SPF” rule
Migadu trial gotchas + what still works when you’re over outgoing limits
SMTP vs public forms when capped (our real backup playbook)
Honesty log of what failed for Frontcountry — dates and error strings included

Who this is for

Solo operators who need a real desk@yourdomain without Google Workspace sticker shock — especially people selling on Gumroad who still send from Gmail.

Not for: bulk newsletter blasting on the same SMTP; people who want us to log into their registrar for $19; legal advice about cold-email rules.

Free sample — Days 0–2

Day 0 — Cloudflare baseline

Get the domain on Cloudflare NS. Decide the local-part (desk@ / hello@ / ops@). Screenshot existing MX/TXT before edits.

Lived note: Mail needs MX + TXT, not a live website. We ran desk@ while apex had no A/AAAA yet.

Confirm NS at registrar → Cloudflare
Inventory records
Don’t delete old Workspace MX until Migadu records are ready

Day 1 — Add Migadu + publish DNS

Create Migadu org (trial is fine to learn — trial quotas are a subset of paid).
Add domain; copy Migadu’s MX/TXT/DKIM instructions verbatim into Cloudflare DNS.
Keep one SPF TXT — merge includes later; multiple SPFs break SPF.
Wait until Migadu shows the domain active.

Day 2 — Mailbox + IMAP/SMTP proof

Create desk@yourdomain; store password in a manager
IMAP imap.migadu.com — login OK
SMTP smtp.migadu.com:465 — AUTH OK
Self-send desk@ → desk@ must work
One external send to a personal inbox — check spam once

Lesson: Auth working ≠ permission to send externally when you’re over plan/trial outgoing limits.

Failure excerpt — the reason this guide exists

After Path 3 outreach batches on 2026-09-10 we got:

550 5.7.1 Reached address outgoing limits for <desk@frontcountrymt.com>

Still worked: IMAP, SMTP AUTH, self-send. Died: external RCPT. Admin banner: plan limits exceeded. Failed retries count toward usage — don’t hammer.

Backup that saved the day: public contact forms with a ~90-word pitch ready before you need them.

Full $19 guide adds Days 3–7 (Gumroad hygiene, warm sends, budget tables, forms playbook, retrospect, FAQ).

Operator card stub

FROM: desk@yourdomain.com
IMAP: imap.migadu.com
SMTP: smtp.migadu.com:465
DNS: Cloudflare MX+TXT per Migadu (one SPF)
DAILY BUDGET: ___ external
IF 550: stop retries → forms only → one probe after rollover

Optional $99 async review

Send screenshots/exports (no passwords): DNS records, Migadu plan/limits, SPF/DKIM notes, Gumroad From/reply-to. You get one written punch list. We do not log into your accounts on the $19 tier; $99 is async review unless a separate paid install is agreed.
