Domain authentication helps Mailcamp verify that you own the domain used in your sender email address. After the domain is verified, Mailcamp can sign outgoing emails from that domain and receiving mail servers can confirm that the messages are authorized.
In Mailcamp, this is managed from Sending domains. You add your domain, copy the DNS records generated by Mailcamp, add them to your DNS provider, and then verify the domain.
Make sure you have access to the DNS settings for the domain you want to authenticate.
Use the domain from your sender address, such as the domain in [email protected].
Do not add a full email address as the sending domain. Add only the domain name.
Check that your plan allows custom sending domains, because some plans may limit this feature.
Keep your DNS provider open in another tab so you can copy the records from Mailcamp into the correct DNS zone.
In Mailcamp, go to Sending domains.
Click the option to add a new sending domain.
Enter the domain name you want to authenticate.
Save the domain.
Open the domain details page to view the DNS records generated by Mailcamp.
On the domain details page, review the DNS table generated by Mailcamp.
Copy each record type, host, and value exactly as shown.
Go to your DNS provider and add the records to the DNS zone for the same domain.
Add the identity verification record if Mailcamp shows one.
Add the DKIM record shown by Mailcamp. DKIM lets Mailcamp sign emails sent from your domain.
Add the SPF record if Mailcamp shows one. If your domain already has an SPF record, update the existing SPF record instead of creating a second SPF record.
Add the DMARC record if Mailcamp shows one and your domain does not already have a DMARC policy.
After adding the DNS records, return to the domain details page in Mailcamp.
Click Verify Now.
Review the status shown beside each DNS record.
If a record is still pending, wait for DNS propagation and try verification again later.
DNS updates can take time to propagate, depending on your DNS provider and record TTL.
After the sending domain is verified, use an email address from that domain as the sender address in Mailcamp.
When creating or editing a list, use a sender email that matches an active verified sending domain.
When setting up a campaign, choose a sender address from the verified domain.
If the domain is not active yet, Mailcamp may prevent you from using that domain as the sender address.
Identity verification: proves that you control the domain.
DKIM: adds a digital signature to outgoing emails so receiving servers can verify that the message was authorized by your domain.
SPF: tells receiving servers which mail servers are allowed to send email for your domain.
DMARC: gives receiving servers a policy for handling messages that fail domain authentication checks.
The record is still pending: wait for DNS propagation, then click Verify Now again.
The host looks duplicated: some DNS providers automatically append your domain name, so enter only the host value required by that provider.
SPF does not verify: make sure the domain has only one SPF TXT record and that Mailcamp's SPF value is merged into the existing record if one already exists.
DKIM does not verify: check that the DKIM host and value were copied completely, including long text values.
DMARC already exists: review your existing DMARC record before replacing it, because your domain should normally have only one DMARC record.
The sender address is not accepted: confirm that the sender email uses the same domain that was added and verified in Sending domains.
