Already added your domain in Ark? Skip to Step 2 to configure your DNS records.

​
Step 1: Add Your Domain in Ark

First, add your domain in the Ark dashboard or via the API. This generates the DNS records you’ll need to add.
  1. Go to Domains in your Ark dashboard
  2. Click Add Domain
  3. Enter your domain name (e.g., mail.yourdomain.com)
  4. Copy the DNS records shown

​
Step 2: Add DNS Records

1

Open Hetzner DNS Console

  1. Go to dns.hetzner.com
  2. Click on your zone (domain)
2

Add the SPF record

Click Add record and enter:
FieldValue
TypeTXT
NameUse the name from the Ark dashboard (e.g., @ for root domain, mail for subdomain)
Valuev=spf1 a mx include:spf.arkhq.io ~all
TTLDefault
Click Add record.
Already have an SPF record? Edit your existing record instead. Add include:spf.arkhq.io before the ~all. You can only have one SPF record per domain.Example: v=spf1 include:spf.arkhq.io include:_spf.google.com ~all

Add the DKIM record

Click Add record and enter:
FieldValue
TypeTXT
NameUse the name from Ark (e.g., ark-xyz._domainkey or ark-xyz._domainkey.mail for subdomains)
ValueThe DKIM value from Ark (starts with k=rsa;t=s;p=...)
TTLDefault
Click Add record.

Add the Return Path CNAME

Click Add record and enter:
FieldValue
TypeCNAME
NameUse the name from Ark (e.g., psrp or psrp.mail for subdomains)
Valuerp.arkhq.io
TTLDefault
Click Add record.

​
Step 3: Verify Your Domain

Return to the Ark dashboard and click Verify DNS records on your domain. Verification typically completes within a few minutes.
Success! Once verified, you can send emails from any address at your domain.

​
Troubleshooting

  • Check record names: Use ark-verify, not the full hostname with your domain
  • Wait for propagation: DNS changes can take a few minutes. Try again shortly.
  • Check for typos: Ensure values were copied exactly from Ark
  • You can only have one SPF record per domain
  • If you have multiple email services, combine them: v=spf1 include:spf.arkhq.io include:_spf.google.com ~all
  • SPF has a 10 DNS lookup limit. Use SPF checker tools to verify
  • Use dnschecker.org to verify records are propagating globally
  • Hetzner DNS changes typically propagate quickly
