​
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

Open Netlify DNS settings

  1. Go to app.netlify.com
  2. Click Domains in the sidebar
  3. Click on your domain
  4. Go to the DNS panel tab

Add the SPF record

Click Add new record and enter:
FieldValue
Record typeTXT
NameUse the name from Ark (leave empty for root domain, or enter subdomain like mail)
Valuev=spf1 a mx include:spf.arkhq.io ~all
TTLLeave default
Click Save.
Netlify auto-appends your domain. For root domains, leave Name empty. For mail.yourdomain.com, enter mail.
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

​
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: Netlify auto-appends your domain. Use ark-verify, not the full hostname
  • Leave Name empty for root: For root domain records, leave the Name field empty
  • Wait for propagation: DNS changes can take a few minutes. Try again shortly.
  • 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
  • Netlify DNS changes typically propagate quickly
