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

What does Omnisend ask me to publish?

To add SPF and DKIM records , choose the domain name you'd like to use. We recommend using your store's domain (e.g., yourstore.com ). You'll need to add the provided records to your domain's DNS.

Omnisend makes the values for your account, so we do not print any here.

Where in Omnisend are my values shown?

To add a new domain, go to Store settings → Domains → Add domain .

In Omnisend, go to Store settings, then Domains, then Add domain.

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

How do I add Omnisend 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 Omnisend 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.

Will p=reject block Omnisend email?

In Omnisend, we advise setting DMARC to p=none with SPF and DKIM alignment=relaxed .

Not once Omnisend 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 Omnisend gives you are on your domain.

Omnisend advises a DMARC policy of none with relaxed alignment.

A valid DMARC record on the main domain is inherited by its subdomains unless you set a different one.

Omnisend also asks that your domain has a DMARC record. A domain has one DMARC record: if you have one, keep it and do not add another.

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