Sending domains

To get deliverability right, Aigeon sends from your own domain, not a generic shared one. Authentication is required for all production sending.

Adding a domain

1. Open Settings → Domains → Add domain.
2. Enter the root domain (example.com) or a subdomain (mail.example.com).
3. Copy the three DNS records shown into your DNS provider:
   • DKIM — a TXT record Aigeon signs outbound mail with.
   • SPF — a TXT record listing Aigeon's sending servers.
   • DMARC — a TXT record telling receivers what to do with unaligned mail.
4. Come back to the Aigeon console and click Verify. Propagation usually takes a few minutes but can be up to 24 hours.

Multiple domains

You can authenticate multiple domains per org and pick which one signs each campaign or flow. A common pattern is to use newsletter.example.com for marketing and mail.example.com for transactional — so complaints on marketing don't damage transactional deliverability.

Warmup

Brand-new domains should be warmed up before you blast your full list. Start with your most engaged 5-10% of contacts on day 1, double each day for the first two weeks. Aigeon's Deliverability score report shows you whether a domain is healthy or needs a slowdown.

Troubleshooting

If verification fails:

• DKIM public key mismatch — the DNS value doesn't match Aigeon's signer. Recopy exactly, including any leading v=DKIM1; prefix.
• SPF lookup limit exceeded — too many include: statements in your SPF record. Flatten with a service like easydmarc.com.
• DMARC policy too strict — start with p=none during setup; tighten to quarantine or reject after a few weeks of clean alignment.
