MailerLite email authentication
Budget newsletter platform aimed at creators and small shops.
SPF record
Add MailerLite to your domain's SPF record with this include:
include:_spf.mlsend.com
A complete record for a domain sending only through MailerLite:
v=spf1 include:_spf.mlsend.com ~all
What it costs you
1 of your 10 DNS lookups. That is the cheapest an include can be — the record it points at contains only IP ranges, with no further includes to follow. Behind it are 2 IP ranges.
Live record
This is what _spf.mlsend.com published when this page was generated:
v=spf1 ip4:185.249.220.0/24 ip4:185.225.161.0/24 ~all
Domains using MailerLite
Found while resolving 293 well-known domains on 2026-08-04 — each authorises
_spf.mlsend.com in its published SPF record:
DKIM
Enable DKIM inside MailerLite 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 MailerLite 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.
