To ensure safe email practices and improve deliverability, MailChimp requires proper domain authentication, with SPF (Sender Policy Framework) being the first critical step. SPF helps to verify that the email sending server is authorized to send emails on behalf of your domain, reducing the likelihood of emails being marked as spam.
Here’s a step-by-step guide on how to configure SPF for MailChimp:
1. Accessing MailChimp Domain Authentication Information
Log in to your MailChimp account.
Navigate to Account Settings: Go to the account settings by clicking your profile icon and selecting Account from the dropdown.
Access the Domains Tab: In the Account Settings menu, click on Domains.
Authenticate the Domain: You will see a list of domains associated with your MailChimp account. Click the Authenticate button next to the domain you wish to authenticate.
2. Modifying Your DNS Record
MailChimp provides you with specific information to modify the DNS record for your domain. This information will be displayed in the Domain Authentication pop-up modal once you click Authenticate.
3. SPF Record Configuration
If you do not already have an SPF record set up for your domain, you will need to create a new one. Here's how to do it:
Record Type: TXT
Host/Name: @ (This represents the root domain; ensure you use "@" as the host to apply the record to the domain itself).
Value:
v=spf1 include:servers.mcsv.net -all
Explanation:
v=spf1specifies the version of SPF being used.include:servers.mcsv.netindicates that MailChimp's servers are authorized to send emails on behalf of your domain.-allis a strict policy that rejects emails from servers not authorized in your SPF record.
Note: It's important to use -all rather than ?all for stricter validation. This ensures that unauthorized email senders are rejected outright, improving security.
4. Adding the SPF Record to Your DNS
To apply the SPF record, you must add it to your domain’s DNS settings:
Log into your DNS provider: Go to your DNS hosting provider’s management console (e.g., GoDaddy, Cloudflare, or your web host’s DNS settings).
Add a New TXT Record: Locate the option to add a new TXT record.
Enter the details: For the Host, enter
@, and for the Value, paste the SPF recordv=spf1 include:servers.mcsv.net -all.Save the record: Once the record is added, save your changes.
5. Verifying the SPF Configuration
After updating the DNS records, return to MailChimp and complete the authentication process by clicking Verify in the Domain Authentication modal. It may take some time for the DNS changes to propagate, but MailChimp will check whether the SPF record has been successfully applied.
Troubleshooting SPF Configuration Issues
If MailChimp doesn’t verify your SPF record immediately, here are a few troubleshooting steps:
DNS Propagation Delay: DNS changes can take anywhere from a few minutes to 48 hours to propagate globally. Check the SPF record after waiting a sufficient amount of time.
Check for Typo: Ensure that the SPF record is entered correctly. A minor mistake, such as an extra space or missing character, can cause validation to fail.
Verify with a DNS Lookup Tool: Use a tool like
digornslookupto confirm that the SPF record has been added to your DNS and is publicly accessible.
Example of dig command:
Copy codedig TXT yourdomain.com
Look for the SPF record in the response, ensuring it matches v=spf1 include:servers.mcsv.net -all.
Conclusion
By configuring SPF for MailChimp, you ensure that emails sent through your domain are authenticated and not flagged as spam. This simple yet essential step in domain authentication helps enhance deliverability, protects against email spoofing, and ensures safe email practices for your business communications.
Note: After completing SPF authentication, you can proceed to set up DKIM (DomainKeys Identified Mail) for even better email security.
