Help Scout email authentication
Shared-inbox support tool for small teams.
SPF record
Add Help Scout to your domain's SPF record with this include:
include:helpscout.net
A complete record for a domain sending only through Help Scout:
v=spf1 include:helpscout.net ~all
What it costs you
2 of your 10 DNS lookups. The include: itself costs one, and Help Scout's record chains to 1 more.
Behind it are 6 IP ranges.
Live record
This is what helpscout.net published when this page was generated:
v=spf1 include:helpscoutemail.com ~all
DKIM
Enable DKIM inside Help Scout 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 Help Scout 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.
