How to Authenticate Your Email Domain for Mailchimp, Constant Contact, and Other Services
If your domain’s DNS is managed through AWS Route 53, you can update your DNS zone records directly from your Zibster account. This makes it easy to verify your domain and improve email deliverability when using third-party email services like Mailchimp, Constant Contact, Flodesk, or others.
Why Email Authentication Matters
Email authentication helps protect your domain from being spoofed and ensures your emails are more likely to reach your subscribers' inboxes. Most email marketing platforms will ask you to add DNS records to authenticate your domain using methods like:
-
SPF (Sender Policy Framework)
-
DKIM (DomainKeys Identified Mail)
-
DMARC (Domain-based Message Authentication, Reporting & Conformance)
Your email provider will usually give you specific TXT or CNAME records that must be added to your domain settings.
Important: DNS management is only available if your domain is using AWS (Route 53) name servers. If your domain is still using legacy name servers at Rackspace, this feature will not be available.

DNS Changes May Take Time
While most DNS updates take effect within a few minutes, it can take up to 48 hours for changes to fully propagate across the internet.
Before You Start
Be sure to get the records you need to add from your provider.
STEP ONE
Access Your DNS Records
- Log into your Zibster account.
- Click DOMAINS in the left-hand menu.
STEP TWO
Open the DNS Zone Editor
- Click the MANAGE DNS button next to your connected domain.
STEP THREE
Add a New DNS Record
- Click NEW DNS RECORD.
- Choose the type of record you’d like to add.
Supported DNS Record Types:
- A Record – Points your domain to a specific IP address.
- CNAME – Redirects one domain name to another.
- MX (Mail Exchange) – Routes email to your mail server.
- TXT – Used for domain verification and email authentication (e.g., SPF, DKIM, DMARC).
- SRV – Used for specific services like VoIP or messaging platforms.
Important: Making incorrect changes to your DNS settings can disrupt your website, email, or other services. Only proceed if you’re confident in the changes or have instructions from a trusted provider.
TTL is default in the control panel.
STEP FOUR
Enter Record Details and Save
- After selecting your record type, fill in the required fields.
- Click ADD DNS RECORD to create the new DNS record.
Deleting a DNS Record
Removing a DNS record can cause services like your website or email to stop working. Deleted records cannot be recovered and will need to be manually re-added.
To delete a DNS record:
- Go to the DOMAINS section and click MANAGE DNS.
- Find the record you want to remove.
- Click DELETE next to the entry.
Confirm the deletion.
