How do I troubleshoot and resolve subdomain conflicts for landing pages in MailerLite?
Understanding Subdomain Conflicts
A subdomain conflict in MailerLite commonly occurs when the subdomain you are trying to assign to a landing page or website is already associated with another purpose, such as domain alignment (sending domain). This is due to the limitations of DNS configurations, where a subdomain can only serve one specific purpose at a time.
Common error messages include "The name conflicts with an existing aligned domain" or no action taking place when attempting to save changes.
Troubleshooting Steps
Follow these steps to resolve subdomain conflicts and properly set up your subdomain for landing pages:
Step 1: Identify the Source of the Conflict
If you receive the error message "The name conflicts with an existing aligned domain," check if the subdomain is already added for domain alignment or authentication.
A similar conflict error also arises if the subdomain is added under the domain alignment feature.
Step 2: Remove Conflicting Domain Alignments
Go to Account Settings > Domains tab of your MailerLite account.
Remove the specific domain with the subdomain you wish to re-use from the "Sending domains" section where it is currently authenticated.
Go to your DNS manager and delete the associated DNS records for MailerLite domain alignment, such as:
- A record pointing to 34.91.249.129
- MX record pointing to mail.litesrv.io
- TXT SPF record: v=spf1 a mx include:_spf.mlsend.com ?all
Refer to your DNS control panel for records that match this configuration.
Re-add the same domain under the "Sending domains" section. This will re-add your domain and show as authenticated, but the alignment subdomain will be completely deleted, ready to be used as a custom subdomain for a landing page.
Step 3: Reconfigure the Subdomain for the Landing Page
To repurpose the subdomain for a landing page, add the subdomain under 'Sites' section.
Ensure you use a different subdomain if you wish to avoid conflicts entirely, e.g., switching from sub1.domain.com to sub2.domain.com.
Step 4: Setup Correct DNS Records
To use a subdomain for a landing page:
Delete any DNS settings that isolate the subdomain as a separate zone.
Add the required CNAME record to your DNS provider’s control panel as instructed by MailerLite. Specific instructions can be referenced through MailerLite’s guides.
Additional Notes
To prevent future conflicts, plan your subdomain usage carefully and ensure its purpose is clear before adding it to MailerLite.
Always verify your DNS changes through the provided DNS record verification in MailerLite.
