How do I set up MailerLite so its email passes DMARC?

Publish the records MailerLite shows in your account for your domain.

01

What does MailerLite ask me to publish?

Add the DKIM as a CNAME record, the SPF as a TXT record, and a Domain verification as a TXT record. Use the Name and Value fields that we provide for you.

MailerLite prints these values in its own documentation, the same for every customer.

MailerLite makes the other values for your account, so we do not print them here.

DKIM: CNAME record at litesrv._domainkey
litesrv._domainkey.mlsend.com
02

Where in MailerLite are my values shown?

Head to the Account settings page. Select the Domains tab. Click Add domain .

In MailerLite, go to Account settings, open the Domains tab, and click Authenticate next to your domain.

Copy each value from there exactly as shown, and add each record at your DNS host.

03

How do I add MailerLite to the SPF record I already have?

SPF implementations MUST limit the total number of those terms to 10 during SPF evaluation, to avoid unreasonable load on the DNS. If this limit is exceeded, the implementation MUST return "permerror".

Add the include MailerLite shows you inside the one SPF record you have, before its last word, and keep every service already in it. Never add a second SPF record: two make the check fail for every message.

An SPF record may make at most 10 DNS lookups. Each include counts, and so do the includes inside it. Past 10, the check fails, so remove services you no longer use before you add a new one.

04

Will p=reject block MailerLite email?

A message satisfies the DMARC checks if at least one of the supported authentication mechanisms: 1. produces a "pass" result, and 2. produces that result based on an identifier that is in alignment

Not once MailerLite signs your email with your domain's DKIM key. DMARC passes when a message passes DKIM or SPF for your own domain, and the DKIM records MailerLite gives you are on your domain.

Before you raise your policy, read your DMARC reports and check that email from MailerLite passes.
