Mailcamp can use Mailcamp-owned domains for some sending and tracking behavior when your account does not have a verified custom domain yet. This helps you start using the platform, but it should not be treated as a replacement for authenticating your own business domain.
For the best sender identity and deliverability, use your own domain for sending and, when available, a branded tracking subdomain for links.
Mailcamp domains may appear when your account is still using default sending or tracking settings.
Sender fallback: if you do not have an active sending domain, Mailcamp may use a sender address on @mailcamp.io.
Tracked links: campaign links may use Mailcamp's default tracking domain unless you set up your own tracking domain.
Hosted system links: unsubscribe, confirmation, and campaign tracking links may use Mailcamp-hosted URLs when no branded domain is configured.
This setup is useful as a fallback, but it gives recipients and mailbox providers less brand context than a verified domain owned by your business.
You may see a Mailcamp sender domain when your list or campaign cannot use a verified custom domain.
Your account does not have an active sending domain yet.
The From email uses a domain that has not been verified in Mailcamp.
Your list is using the default sender settings generated by Mailcamp.
Your plan or account setup does not allow the custom sending domain you are trying to use.
If this happens, review your sender settings before sending a campaign to a large audience.
A verified sending domain gives your campaigns a clearer identity and helps mailbox providers evaluate your email correctly.
Your From email can use your own domain, such as [email protected].
Mailcamp can verify your domain with identity, DKIM, SPF, and DMARC records.
Your sender identity is more consistent across campaigns.
Your recipients are more likely to recognize the sender.
Using your own domain does not guarantee inbox placement, but it is the recommended setup for serious email sending.
To stop relying on a Mailcamp sender domain, authenticate your own domain in Mailcamp.
Go to Sending domains.
Add the domain you want to send from.
Copy the DNS records shown by Mailcamp to your DNS provider.
Add the identity, DKIM, SPF, and DMARC records exactly as shown.
Return to Mailcamp and click Verify Now.
After the domain is active, use a From email from that domain in your list or campaign settings.
DNS updates can take time. If the domain does not verify immediately, wait for DNS propagation and try verification again.
A tracking domain is used for tracked campaign links. If your account supports it, you can create a branded tracking subdomain such as link.yourdomain.com.
Go to Tracking domains.
Add the tracking subdomain you want to use.
Create the CNAME record shown by Mailcamp at your DNS provider.
Verify the tracking domain in Mailcamp.
Select the tracking domain when setting up your campaign.
This keeps tracked links closer to your brand instead of relying on a Mailcamp default tracking URL.
Keep your sending identity consistent and easy to recognize.
Do not send business campaigns from public mailbox domains if you can use your own verified domain.
Do not use a From email from one domain while your authenticated sending domain belongs to an unrelated domain.
Do not create multiple SPF records for the same domain. Merge SPF values into one record instead.
Do not assume a Mailcamp fallback sender will perform the same as your own authenticated domain.
If your campaign still uses a Mailcamp sender after you added your domain, check these items:
Confirm the sending domain status is active.
Confirm the From email uses the verified domain.
Check whether your list has default From settings that still use @mailcamp.io.
Review the campaign setup before sending.
If the issue continues, check your plan limits or contact support.
Once your sending domain and tracking domain are verified, your campaigns can use a more consistent branded setup.
