A domain is your company's web address. It is part of your company's email address that you use to send emails. Your company's domain is the information after the @symbol in an email. The domain name helps your customers recognize and identify your email address.
Domains play a vital role in dictating your email deliverability. Email deliverability is the ability for your emails to reach the inbox and not be blocked or labeled as spam. Domain reputation is crucial to maintain good email deliverability. For more information about reputation, see Reputation.
Note: Acoustic will configure domains for your org. To create your domains, reach out to the Acoustic provisioning team. You can view the domains created and their status from the main menu > Settings > Administration > Email domains. The domain pages are read-only and cannot be edited.
Types of domains
Acoustic provides the ability to create Custom domains and From domains.
You can have a unique branded custom domain that identifies with your company and brand. When you use a custom domain in your email campaigns, you can promote brand consistency and trust. The hover links and URLs in your emails will align with your branding. Your email recipients can validate the links, which will improve trust.
For more information on setting up a custom domain, see Provision a custom domain.
You can have domains as From domains to use as the sender domain in the header of an email. The from domains are visible to the recipient in the emails From address field after the @sign.
Important: The From address used when sending emails must use a From domain set up in the Settings > Administration > Email domains page; otherwise, email deliverability will be affected.
You can restrict emails sent to use only a configured From domain by requesting the Acoustic support team to set the Restrict From Domain field Yes, in the Settings > Administration > Organization settings >From Domain Settings page.
Note: You must have a custom domain created before creating a From domain.
For more information on setting up a custom domain, see Set up a From domain.
Host your domain
You can host your domain with Acoustic and let Acoustic manage your Domain Name System (DNS) records, or you can self-host to manage records within your organization.
Provisioning IP address
Domains must point to your server's IP address. You can add your domain to an existing IP address or create a new one. For more information, see Provisioning a new IP.
Domain Keys Identified Mail (DKIM) record is a security standard to ensure emails are authorized and encrypted for the domain. You can choose 1024-bit or 2048-bit for your key encryption length. For more information, see Sender Policy Framework (SPF) and Domain Keys Identified Mail (DKIM).
You can view the status of the domains on the Domains listing page.
Connected: The domain is configured, connected, and ready to use.
Configuring: When the domain was submitted for verification. The configuration process can take some time. Refresh and check the domain page to check the status. When ready, the status changes to connected.
Unverified: If the domain is not verified. When the DNS records are updated, and you are ready to submit your domain verification, you can select verify domain from the three-dot menu for the domain.
Manage domain IP addresses
IP pools are created within a custom domain. You must select at least 2 IP addresses to create an IP pool. You can view the list of IP addresses and IP pools by clicking the three-dot menu > Manage domain IP addresses.
If you must send a high volume of emails regularly, you can create IP pools to handle the high volume. IP Pools are groups of IP addresses you can use to send emails. IP pools can help improve email deliverability and reputation. `
Note: You can create IP Pools only for custom domains.
For more information, see Set up IP pooling.
A VMTA (Virtual Mail Transport Agent) server is used within a database or query to balance your IP addresses and avoid setting off spam triggers within an email client. You can use a VMTA within a contact source or database in a program to pass contacts through your program. Consistent sending patterns and cadence will help ensure your messages go to their inbox rather than spam or junk folders.
For more information, see VMTA servers.
DMARC stands for "Domain-based Message Authentication, Reporting & Conformance", an email authentication, policy, and reporting protocol. The DMARC settings define how strictly messages should be checked and specify what actions they want a mailbox provider to take with unauthenticated email.
For Acoustic-hosted domains, Acoustic adds a DMARC record into your DNS. You can review and update the DMARC settings by accessing the DMARC setting page for your domain from the three-dot menu > DMARC settings.
For self-hosted domains, we strongly suggest you add a DMARC record to your DNS if you don't already have one.
For more information, see the following:
- Domain-based Message Authentication, Reporting, and Conformance (DMARC)
- New DMARC requirements for senders
- New sending requirements from Gmail and Yahoo
Secure Sockets Layer (SSL) is a security protocol that authenticates and encrypts the connection from the domain server. You must have SSL certificates for your domains to send secure emails.
Acoustic provides auto-renewing and managed SSL certificates at no additional cost. When a new domain is created, an SSL certification must be created. Your DNS records must be updated for the SSL certificate to be approved.
Note: If you use a custom SSL certificate, you are responsible for maintaining the certificate's integrity. Contact Acoustic support to confirm SSL certificate usage.
To send emails, you must delegate the domain to Acoustic. When you delegate the domain, you are giving Acoustic the authority to use the domain for sending emails.
When you delegate the domain to Acoustic, you must update the Name Server (NS) records provided by Acoustic in your DNS system for your domain.
You can download the list of Name Server (NS) records by clicking the three-dot menu and clicking Download DNS configuration file.
For more information, see Delegate a top-level domain and subdomain for email marketing.
You must verify your domain for the configuration process to complete and be connected. Acoustic verifies if the domain has been correctly configured when you submit your domain for verification. Your DNS records must be updated, and the necessary records must be synchronized with our systems for the verification to be complete. If the validation fails, you will receive an error.
To verify your domain,
- For the domain with the status as unverified, click the three-dot menu and click Verify Domain.
- A Verify domain modal pops up. If your DNS records are up-to-date, click Confirm to verify the domain.
- Once the verification is complete, the Domain status will be updated from unverified to Connected.
IP warming is the practice of establishing sender reputation for a new IP address. Sender reputation is a score that an ISP (Internet Service Provider) assigns to an organization that sends emails. It's a crucial component of your email deliverability. The higher the score, the more likely an ISP will deliver emails to your recipients' inboxes.
The IP warming process gets the inbox providers used to receiving emails from your IP address. IP warming is important to ensure your messages are delivered consistently.
When you create a new IP address, the IP warming for the new IP address has yet to start. To successfully warm the IP, start sending emails using this IP address and gradually increase the email volume. For more information, see IP-warming.
