How to Setup Domain on DigitalOcean

Step-by-step guide to configure DNS records on DigitalOcean for Aurora SendCloud. Learn to set up SPF, DKIM, MX, and DMARC records for optimal email delivery.

Overview

This guide walks you through adding a primary domain or subdomain in DigitalOcean and configuring the DNS records required by Aurora SendCloud. It assumes you already have a DigitalOcean account.

If you encounter errors or issues when configuring DNS records in DigitalOcean, contact DigitalOcean's support team—they can identify and resolve the issue most quickly.

Choose a Primary Domain or Subdomain

Before proceeding, decide whether to use your primary domain or a subdomain. We recommend reviewing the following Aurora SendCloud article:

How to choose a sending domain

Here is a brief review of two key terms:

  • Primary domains — for example, aurorasendcloud.com, mydnsexample.com, or google.com.
  • Subdomains — for example, relay.aurorasendcloud.com, sc.mydnsexample.com, or mail.google.com.

Subdomains have an additional prefix (sometimes multiple prefixes) before the main domain. In most cases, using a subdomain with Aurora SendCloud is the preferred option.

Once you've made your decision, add the domain or subdomain to your Aurora SendCloud account, and our system will generate the various DNS records required.

Register a New Domain

To create a new domain or subdomain hosted on DigitalOcean:

  1. Log in to your DigitalOcean account.
  1. Click the Networking option.

  2. Follow the prompts to complete the domain registration process.

Configure the Domain

Once you have added the domain, access it by following these steps:

  1. Log in to your DigitalOcean account
  2. Go to Domain Management.
  3. Find the domain you want to configure and click Manage.
  4. Click Add Record (or a similar option) to configure the DNS records.

Configure SPF

SPF (Sender Policy Framework) records help protect your domain from spoofed email and reduce the likelihood of your messages being marked as spam.

SPF Record for a Primary Domain

In your DigitalOcean dashboard, enter the SPF record information shown in the Aurora SendCloud dashboard:

FieldValue
Record TypeTXT
Host Record@
Record Valuev=spf1 include:sendcloud.org ~all (when activating multiple regions, configure according to the values shown in your Aurora SendCloud dashboard)
TTL600 (seconds)

Note: If you already have an SPF record for this primary domain, add include:sendcloud.org to the existing record. Place it after v=spf1 and before ~all.

SPF Record for a Subdomain

FieldValue
Record TypeTXT
Host RecordSubdomain Prefix (e.g., sc)
Record Valuev=spf1 include:sendcloud.org ~all (when activating multiple regions, configure according to the values shown in your Aurora SendCloud dashboard)
TTL600 (seconds)

Configure DKIM

DKIM (DomainKeys Identified Mail) records help verify your domain to prevent forged emails and reduce the likelihood of your messages being marked as spam.

DKIM Record for a Primary Domain

FieldValue
Record TypeTXT
Host Recordsendcloud._domainkey (or the value assigned by Aurora SendCloud for your domain)
Record Valuek=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUA... (use the value shown in your Aurora SendCloud dashboard)
TTL600 (seconds)

Note: Your DKIM host record may have a value such as default._domainkey or sc._domainkey. Use the value assigned by Aurora SendCloud for your domain.

DKIM Record for a Subdomain

FieldValue
Record TypeTXT
Host Recordsendcloud._domainkey.subdomain prefix (e.g., sendcloud._domainkey.sc)
Record Valuek=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUA... (use the value shown in your Aurora SendCloud dashboard)
TTL600 (seconds)

Configure MX Records

MX records specify where emails sent to your domain should be delivered.

MX Record for a Primary Domain

FieldValue
Record TypeMX
Host Record@
Record Valuemx.sendcloud.org (when enabling multiple regions, configure according to the values shown in your Aurora SendCloud dashboard)
Priority10
TTL600 (seconds)

Note: Ensure that only Aurora SendCloud MX records are configured for your domain. MX records from other email providers can cause unpredictable delivery behavior.

MX Record for a Subdomain

FieldValue
Record TypeMX
Host RecordSubdomain Prefix (e.g., sc)
Record Valuemx.sendcloud.org (when enabling multiple regions, configure according to the values shown in your Aurora SendCloud dashboard)
Priority10
TTL600 (seconds)

Configure DMARC

DMARC (Domain-based Message Authentication, Reporting & Conformance) is an email authentication protocol that protects your domain from spoofing and phishing attacks. It builds on SPF and DKIM to provide policy guidance for inbox providers.

DMARC Record for a Primary Domain

FieldValue
Record TypeTXT
Host Record_dmarc
Record Valuev=DMARC1; p=none; rua=mailto:[email protected]; ruf=mailto:[email protected]; fo=1
TTL600 (seconds)

Parameter Description:

  • v=DMARC1: Protocol version
  • p=none: Monitor mode — no enforcement
  • p=quarantine: Quarantine mode — messages that fail verification are sent to spam
  • p=reject: Reject mode — messages that fail verification are rejected
  • rua: Email address for aggregate reports
  • ruf: Email address for forensic reports
  • fo=1: Generate a failure report when any authentication mechanism fails

DMARC Record for a Subdomain

FieldValue
Record TypeTXT
Host Record_dmarc.Subdomain prefix (e.g., _dmarc.sc)
Record Valuev=DMARC1; p=none; rua=mailto:[email protected]
TTL600 seconds

Update Domain Registrar and Name Server Records

If you recently migrated from another DNS hosting provider (or are currently migrating) and your Aurora SendCloud DNS records fail to verify, you may need to update your domain's registration information.

When switching DNS hosting providers, you must update the name server (NS) records in your registrar's system. Your registrar is the company through which you purchased and registered your domain name.

If you need help identifying your registrar, use the ICANN WHOIS website.

Support

If you need help, contact the Aurora SendCloud support team from the Support page in your Aurora SendCloud control panel.

Important Notes

  • The DNS record values in this guide are examples only. Always refer to the actual values displayed in your Aurora SendCloud dashboard.
  • After configuration, DNS records may take anywhere from several minutes to several hours to propagate globally.
  • Set the TTL to a low value (for example, 300–600 seconds) for faster verification. After successful verification, you can increase it as needed.
