Does Mailchimp handle DMARC for you?

The short answer

Partly. When you set Mailchimp up properly, it asks you to add three settings to your domain, and one of them is the protection setting you’re asking about (DMARC). But that setting lives on your domain, not in Mailchimp. Mailchimp doesn’t read the daily reports that setting brings in, doesn’t check your other tools, and never turns your protection up. And if you already have one, adding Mailchimp’s as a second one breaks it.

Check your own email first. Free, about 90 seconds. You get a grade and a plain-English list of what's working and what isn't.

First: verified isn’t the same as authenticated

Mailchimp has two steps with similar names, and lots of people stop after the first one.

VerifiedYou click a linkMailchimp emails you.Proves you own it.AuthenticatedThree settings addedto your domain. Sendsin your business’s name.NO CHANGEINBOX
Verifying proves you own the address. Authenticating is the step that changes where your newsletter lands.
  1. Verifying is clicking a link Mailchimp emails you. It proves you own the address. Mailchimp says it doesn’t help your email reach the inbox at all.
  2. Authenticating is adding three settings where your domain is managed (often GoDaddy, Cloudflare, Squarespace, Wix or your web host). This is the step that helps your email reach the inbox.

To see which one you’ve done, log in to Mailchimp, click your profile picture, choose Account & billing, then the Domains tab. If your domain says Authenticated, you’re set. If it doesn’t, the steps below are for you.

A real example

Lisa runs a yoga studio and sends a monthly newsletter from lisa@sunriseyoga.com through Mailchimp. She verified her address when she signed up and never did anything else. Her newsletter goes out with Mailchimp’s name on it instead of her studio’s, and more and more of it lands in junk. Gmail and Yahoo now want bigger senders to authenticate, and Mailchimp’s own screens warn about it.

Lisa authenticates her domain, and her newsletter now goes out with her studio’s name on it. But her booking app still sends class reminders that aren’t set up the same way. Mailchimp doesn’t know about the booking app, so it can’t tell her. That’s the part Mailchimp doesn’t handle.

Set it up in Mailchimp

  1. Log in to Mailchimp, click your profile picture and choose Account & billing. Click the Domains tab.
  2. Click Start authentication next to your domain, then pick the company that manages your domain from the list.
  3. Choose the automatic option if you can. Mailchimp connects to your domain company, you log in there, and it adds the settings for you.
  4. Or add them yourself: Mailchimp shows two lines for the email signature and one line for the protection setting. Copy each one into your domain company’s settings, or forward them to whoever looks after your website.
  5. Wait for the email from Mailchimp. Most domains are done within minutes. It can take up to 48 hours. When it’s done, your domain shows Authenticated.
Already have this protection setting? Don’t add a second one. A domain can only have one. If Mailchimp adds another next to the one you have, Gmail and Outlook ignore both, and you lose your protection. Run the free check first: it tells you whether you already have one. If you do, keep yours and skip that line of Mailchimp’s instructions.

What Mailchimp leaves to you

The protection setting covers every email sent from your domain, not just your newsletter. So after setup:

  1. Someone has to read the reports. Gmail, Outlook and others send a daily report of everything that sent email as you. Those go to the address in your setting, and Mailchimp doesn’t look at them.
  2. Your other tools still need their own setup. Your everyday mailbox, your invoicing app, your website form and your booking app each have their own version of “authenticate your domain”. The guide to tools that don’t send as you shows how to check each one.
  3. The protection starts in watch-only mode. Fakes in your name still get delivered. Turning it up to junk or block is done slowly, once every real tool passes, or you’ll block your own email.

That’s the work the Email Fix does: it finds every tool sending as you, including the ones you forgot, and SenderFix Monitor reads the reports and walks you up to full protection one safe step at a time.

What this guide can’t do for you

It covers the common causes. It can’t tell you which of your tools is the one that’s failing, or give you the exact settings for your business and the company that manages your domain. That’s what the Email Fix does. We check every tool that sends email for you and give you steps written for your setup. If we can't find what's wrong with your email settings, you get your $299 back. The guarantee covers your email settings. No settings can fix email sent to people who didn't ask for it, like bought lists or mass emails.

Common questions

Does Mailchimp set up DMARC for me?

It asks you to add it while you authenticate your domain, and its automatic option can add it for you. But it's a setting on your domain that covers all your email. Mailchimp doesn't read the reports or turn the protection up for you.

I already have DMARC. Should I add Mailchimp's too?

No. A domain can only have one. Two of them cancel each other out. Keep the one you have and skip that line of Mailchimp's instructions.

I verified my domain in Mailchimp. Isn't that enough?

No. Mailchimp says verifying doesn't affect whether your email reaches the inbox. Authenticating is the separate step that does. Check the Domains tab under Account & billing for the word Authenticated.

Can I send Mailchimp campaigns from a Gmail address?

Mailchimp can't authenticate free addresses like Gmail or Yahoo, and it recommends sending from an address at your own business domain instead.

For your IT person or web developer

You can forward this page as it is. Everything below is written so someone who doesn't work with email settings every day can follow it.

1. Check what's already published

Look up _dmarc.yourdomain.com (TXT). If a v=DMARC1 record exists, keep it and don't publish Mailchimp's: two DMARC records at the same name make receivers ignore DMARC for the domain (RFC 7489 §6.6.3). If you want Mailchimp's reports too, add its address to the existing rua= tag instead.

2. Publish Mailchimp's records

In Mailchimp: profile icon → Account & billing → Domains → Start authentication. Manual setup gives two CNAMEs for DKIM and one TXT at _dmarc. Some DNS hosts append the domain to the Name field: enter just the label Mailchimp shows (for example k2._domainkey), not the full name.

3. Wait for validation

Usually minutes, up to 48 hours. The domain then shows Authenticated. If you change the CNAMEs later, disable authentication in Mailchimp first and re-authenticate after the change.

4. Check it worked

Send a test campaign to a Gmail address, open it, click the arrow under the sender's name and confirm signed-by shows the business's domain. Show original should read DKIM: PASS and DMARC: PASS.
