Getting Started

Send your first authenticated email in under 5 minutes.

1 Create an account

Sign up at aimail.nu — free, no credit card required. You'll get 1,000 emails/month forever.

2 Add your domain

Go to Domains → Add Domain. Enter your domain name. We generate DKIM, SPF, and DMARC records automatically.

# DNS records to add in your DNS provider:
agenticmail._domainkey TXT "v=DKIM1; k=rsa; p=MIIBIjAN..."
@ TXT "v=spf1 include:mail.aimail.nu ~all"
_dmarc TXT "v=DMARC1; p=quarantine; rua=mailto:[email protected]"

3 Get your API key

Go to Settings → API Keys → Create key. Copy your key — it's shown only once.

4 Send your first email
