Do I need to set up DNS and DKIM myself?

No. Order a domain through your plan and DKIM and deliverability are handled for you; outbound is relayed through SES in the EU.

Is there a free way to try it?

No. Every plan starts with Starter and includes an instant mailbox on a Sairaph domain, so you can send and receive over REST and MCP as soon as your plan is active.

How much does it cost?

Plans are priced per month or annually, with an entry plan aimed at small projects - see pricing for the current live figures.

Can I use my own domain?

Yes - connect a domain you already own (add the DNS records we give you, verify it, then host mailboxes on it), or register a new one through us, where the first-year registration is covered by your plan's domain credit.

REST or MCP - which should I start with?

Either. REST is a few curl calls; MCP plugs the mailbox straight into an MCP-capable agent as tools. The quickstart covers both.

Agent email you can ship this weekend

You don't want to become a mail-server admin to ship a side project. Get a managed domain, a real mailbox, and send-and-receive over REST or MCP - without running DNS, DKIM, or IMAP yourself.

Get started Read the quickstart

cURL

curl https://mail.sairaph.com/api/v1/mailboxes/$MAILBOX_ID/outbound \
  -H "Authorization: Bearer $SAIRAPH_MAIL_KEY" \
  -H "Idempotency-Key: $(uuidgen)" \
  -H "Content-Type: application/json" \
  -d '{
    "to": ["agent@acme.dev"],
    "subject": "Your verification code",
    "body_text": "Reply with APPROVE to continue."
  }'

Your agent's first email - one idempotent POST.

Running mail infrastructure is a project of its own

Doing email yourself means a domain, DNS records, DKIM/SPF/DMARC, an SMTP relay that won't get you blocklisted, and an IMAP server to read replies - before you've written a line of your actual idea. For a weekend project that's the whole weekend. Sairaph Mail hands you a managed mailbox with deliverability handled, so you spend your time on the thing you're building.
