SPF, DKIM and DMARC for Klaviyo

Short answer: Klaviyo mail passes Gmail, Yahoo and Microsoft checks when you turn on DKIM with your own domain and publish a DMARC record at _dmarc (start with p=none). The exact records and clicks are below.

SPF	—	Not needed on your root domain: Klaviyo sends from a branded subdomain (for example `send.yourdomain.com`) that points to Klaviyo.
DKIM	CNAME / TXT	Dynamic (recommended): the subdomain is delegated with NS records `ns1`–`ns4.klaviyo.com` and Klaviyo publishes DKIM itself. Static: CNAMEs for the subdomain plus `km1._domainkey` and `km2._domainkey` (marketing; `kt1/kt2` transactional, `ks1/ks2` service). Both add a TXT `klaviyo-site-verification=…` at `@`.
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 Klaviyo click your company name → Settings → Domains → Add domain.
Pick a subdomain you don't use for anything else, e.g. send for marketing mail.
Choose Dynamic routing (NS records) if your DNS provider supports NS records, otherwise Static (CNAME records).
Copy the records and the verification TXT exactly as Klaviyo shows them into your DNS.
Turn on Add DMARC record or publish v=DMARC1; p=none; at _dmarc yourself.
DNS can take up to 48 hours; then verify the domain in Klaviyo.

Mistakes that break it

Many DNS panels add your domain automatically: send.yourdomain.com typed in full becomes send.yourdomain.com.yourdomain.com. Enter only the host part.
Some DNS providers don't accept underscores in CNAME names, which static setup needs. Use dynamic routing there.
Already have a DMARC record? Don't add a second one or lower its policy to p=none.

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.
