Channel

Email

Email is the core channel. Both marketing and transactional mail are sent from your own domain — authenticated, tracked and warmed for the inbox.

What you'll need

  • A verified sending domain (SPF/DKIM/DMARC)
  • Opt-in contacts with email addresses

What you can send

  • Marketing: newsletters and campaigns to lists and segments, with A/B testing.
  • Transactional: order confirmations, receipts, password resets via the API.
  • Lifecycle: automated welcome, cart and win-back flows.

Set it up

  1. 1

    Connect your domain

    Authenticate a sending subdomain — see the “Connect a sending domain” guide.

  2. 2

    Import opt-in contacts

    Bring in subscribers and record their email consent.

  3. 3

    Send

    Create a campaign, or POST to /v1/messages with channel "email" for transactional mail.

Deliverability & tracking

Opens and clicks are tracked from your own tracking subdomain. Bounces and complaints feed suppression lists automatically, protecting your reputation on every subsequent send.

Sending from an unverified domain is the number-one cause of spam-foldering. Verify first.

Frequently asked questions

Can I send transactional and marketing from the same domain?

Yes, though many senders use separate subdomains (e.g. mail. for marketing, tx. for transactional) to isolate reputation.

Do you support SMTP?

Integration is via the REST API and the cabinet; transactional sends use POST /v1/messages.
