You will need to add the DMARC record to your root domain. Steps are provided below. For more information, please visit Customer.io directly.

DMARC Record Check

You can quickly check to see if you have a DMARC record in place already using DMARCian. Once you’re on the site, simply add your domain and click Inspect the Domain.

Once you click Inspect the Domain, you will see one of the following:

Response Option 1: If you see this image, this indicates there is no DMARC record published. You will want to get this added to your root domain. Please jump to "Create a DMARC Record to your Root Domain" for next steps!

Response Option 2: If you see this image, you're all set! Please reach out to support@union.fit to let us know that your DMARC record was marked as valid. We will verify on our end just to be certain.

Response Option 3: If you see this image, please reach out to support@union.fit and provide a screenshot. We will verify on our end just to be certain!

Create a DMARC Record to your Root Domain

If you need to create a DMARC record, you can quickly add this to your root domain:

1. Sign in to your host domain
2. Add a new record
3. Type: TXT
4. Name (Host): _dmarc
5. Value: v=DMARC1; p=none

Here are some common providers: Cloudflare | Go Daddy | Name.com . For the full list, please visit dmarcian support doc.

Once these have been added, please be sure to visit your Customer.io Workspace settings to click Verify. Please feel free to reach out to support@union.fit to let us know this has been updated. We will verify on our end that these records are verified.

Notes:

• Learn more at https://dmarc.org/overview/
• Do not add aspf=s or adkim=s

Unsubscribe Link

Ensure that all emails contain an unsubscribe link.

Each of your emails sent from Customer.io must contain one of the following:

• {% unsubscribe %}
• {% unsubscribe_url %} → this is my favorite :) 
• {% manage_subscription_preferences_url %} (available if you are using our Subscription Center feature)

You may have had some support with your email templates that included an “unsubscribe” variation. However, if you have any questions, please don’t hesitate to reach out to Union Support!

Spam Below 0.3%

Ensure you are following Customer.io Deliverability Best Practices

Set a schedule to check your Customer.io Dashboard periodically - it displays spam complaints from all email providers except Gmail. Make sure this number stays under 0.3%.

If you do not send more than 1,000 emails in a 24 hour period:

• Focus on monitoring your spam rate with other providers in the Customer.io Dashboard, as described above.
• Ensure you’re following the Deliverability Best Practices, as described above.

If you send more than 1,000 emails in a 24 period, follow these additional steps:

• Sign up for Google Postmaster Tools. Instructions here.
• Set a schedule to periodically monitor the “Spam Complaints” area. Make sure this number stays below 0.3%.
