When you use custom domains, you reduce the likelihood that a message is flagged as a phishing attempt.

The custom domain also re-brands the "hover" links - when the cursor is placed over a link, the custom domain is visible instead of a generic address.
The following examples show two options for creating custom domains.
- Client-owned top-level domain: You buy a domain similar to your top-level domain, such as
- Client-owned subdomain: You provide a subdomain of the primary corporate domain, such as
In both cases, you must delegate the DNS to Acoustic Campaign.
Why does Acoustic Campaign host DNS records?
Acoustic Campaign can make immediate changes to relevant DNS records in the event of security issues, including the following actions:
- Make necessary routine updates to SPF, DKIM, and DMARC records.
- Add any DNS records that improve delivery or access to deliverability data, such as Google Postmaster Tools.
Why can't I use a top-level corporate domain?
Unfortunately, Acoustic Campaign cannot use a top-level domain because it cannot host the DNS records for an existing top-level domain. Instead, try an unused top-level domain or a subdomain of an existing corporate domain.
What happens if I leave Acoustic Campaign?
If you end your relationship with Acoustic Campaign, you can delegate the DNS to your new provider or erase it. You always retain ownership over your DNS.
