Migadu email authentication
Small independent mail host billed per message rather than per mailbox.
SPF record
Add Migadu to your domain's SPF record with this include:
include:spf.migadu.com
A complete record for a domain sending only through Migadu:
v=spf1 include:spf.migadu.com ~all
What it costs you
4 of your 10 DNS lookups. The include: itself costs one, and Migadu's record chains to 3 more.
Behind it are 23 IP ranges.
Live record

Domains using Migadu
Found while resolving 293 well-known domains on 2026-08-04 — each authorises
spf.migadu.com in its published SPF record:
DKIM
Enable DKIM inside Migadu and publish the selector record it generates. DKIM matters more than SPF for deliverability, because a DKIM signature survives forwarding while SPF does not — see how selectors work.
DMARC
Neither SPF nor DKIM protects the address your recipients actually see until DMARC ties them
to it. Once Migadu is authenticating, publish a DMARC record — start at
p=none with a reporting address and
tighten from there.
Check it worked
DNS changes take minutes to hours to propagate. Once published, run the domain through the checker — it resolves the full include chain and reports the real lookup count.
