SPF, DKIM and DMARC for MailerLite

Short answer: MailerLite mail passes Gmail, Yahoo and Microsoft checks when you turn on DKIM with your own domain, add include:_spf.mlsend.com to your one SPF record and publish a DMARC record at _dmarc (start with p=none). The exact records and clicks are below.

SPF	TXT at `@`	v=spf1 include:_spf.mlsend.com ~all Copy the exact SPF value from your MailerLite account. Already have an SPF record? Merge `include:_spf.mlsend.com` into it instead of adding a second record.
DKIM	CNAME / TXT	CNAME `litesrv._domainkey` → `litesrv._domainkey.mlsend.com`, plus a verification TXT value at `@` that MailerLite gives you.
DMARC	TXT at `_dmarc`	v=DMARC1; p=none; rua=mailto:dmarc@yourdomain.com Start with `p=none` and a mailbox you read, or a free report address that turns the reports into a dashboard; build your own.

Step by step

In MailerLite open Account settings → Domains → Sending domains → Add domain, then click Authenticate.
Add the DKIM CNAME, the SPF value and the verification TXT it shows (at @, or at your subdomain if you send from one).
Click Check DNS records once DNS has updated (up to 24 hours).
No DMARC record yet? Publish one at _dmarc with p=none.

Mistakes that break it

On Cloudflare, set the DKIM CNAME to DNS only (grey cloud), not proxied.
Two records starting with v=spf1 make SPF fail. Keep one.

Check that it worked

After the fix, keep an eye on it: free DMARC monitoring shows every service that sends mail as your domain and which ones fail, in plain English.

Rather not touch DNS? I set up SPF, DKIM and DMARC without breaking your other senders, with a before/after report.
