Documentation

Reference for setting up an account, provisioning mailboxes and IPs, configuring DNS, sending and receiving mail, and using the HTTP API.

Getting started

Create an account, set up a workspace, and place your first order.

  • Sign up at /signup. The flow has 3 steps: account, workspace, ready.
  • Open the order wizard from the dashboard and choose mailbox count, domain(s), and dedicated IP count.
  • Pay through Stripe Checkout. Provisioning starts when the webhook is received.
  • Credentials appear in the dashboard once provisioning finishes (typically under 10 minutes).

Domains: buy or BYO

Every order requires at least one domain. You can register one through adbtd or bring your own.

  • Buy: select a name in the order wizard. adbtd registers it and configures DNS.
  • BYO: enter the domain. adbtd generates the records, which you publish at your registrar.
  • Records published: A, MX, SPF (TXT), DKIM (TXT), DMARC (TXT), MTA-STS, TLS-RPT.
  • Verification runs automatically. The dashboard shows the current state of each record.

Dedicated IPs

Every account uses at least one dedicated IP. Shared pools are not offered.

  • Additional IPs can be ordered from the dashboard at any time.
  • IPs can be assigned to specific domains and reassigned later.
  • Released IPs are held for 90 days before being reused for another account.
  • PTR is configured per customer domain and is FCrDNS-aligned.

SMTP and IMAP

Standard ESMTP. No proprietary protocols.

  • SMTP submission supports STARTTLS and implicit TLS. Host, port, and per-mailbox credentials are listed in the dashboard.
  • IMAP retrieval uses the same host on standard ports.
  • Outbound mail is signed with DKIM (d=<your-domain>). SPF and Return-Path are aligned to your domain.
  • No per-message pricing. Daily volume is governed by the acceptable use policy.

Billing

Two line items: mailboxes and dedicated IPs. Monthly subscription billed by Stripe.

  • $1.99 / €1.99 / £1.99 per mailbox per month.
  • $19 / €19 / £19 per dedicated IP per month.
  • Quantity changes are pro-rated within the billing cycle.
  • Currency is set at first checkout (USD, EUR, or GBP) and cannot be changed afterwards.

HTTP API

Manage resources and send or receive mail programmatically.

  • Full reference at /docs/api.
  • Authenticate with a per-workspace API key (Authorization: Bearer adbtd_live_…).
  • Outbound mail goes through the tenant's own SMTP; inbound is read via IMAP.
  • Rate limits are applied per endpoint group: default, send, and fetch.

Status and support

Operational status, contact information, and policy links.

  • Status page: /status.
  • Support: hi@adbtd.com.
