The Marketing API offers two platforms that sellers can use to promote and advertise their products: Promoted Listings is an eBay ad service that lets sellers set up ad campaigns for the products they want to promote. eBay displays the ads in search results and in other marketing modules as SPONSORED listings. If an item in a Promoted Listings campaign sells, the seller is assessed a Promoted Listings fee, which is a seller-specified percentage applied to the sales price. For complete details, refer to the Promoted Listings playbook.Promotions Manager gives sellers a way to offer discounts on specific items as a way to attract buyers to their inventory. Sellers can set up discounts (such as "20% off" and other types of offers) on specific items or on an entire customer order. To further attract buyers, eBay prominently displays promotion teasers throughout buyer flows. For complete details, see Promotions Manager. Marketing reports, on both the Promoted Listings and Promotions Manager platforms, give sellers information that shows the effectiveness of their marketing strategies. The data gives sellers the ability to review and fine tune their marketing efforts.Store Email Campaign allows sellers to create and send email campaigns to customers who have signed up to receive their newsletter. For more information on email campaigns, see Store Email Campaigns.Important! Sellers must have an active eBay Store subscription, and they must accept the Terms and Conditions before they can make requests to these APIs in the Production environment. There are also site-specific listings requirements and restrictions associated with these marketing tools, as listed in the "requirements and restrictions" sections for Promoted Listings and Promotions Manager. The table below lists all the Marketing API calls grouped by resource.

**Send emails fast and with confidence through our easy to use [REST](https://en.wikipedia.org/wiki/Representational_state_transfer) API interface.** # Overview This is the API interface to the [Mail Baby](https://mail.baby/) Mail services provided by [InterServer](https://www.interserver.net). To use this service you must have an account with us at [my.interserver.net](https://my.interserver.net). # Mail Orders Every sending account in MailBaby is backed by a **Mail Order** — a provisioned sending credential with a numeric `id` and a corresponding SMTP username (`mb`). Most calls accept an optional `id` parameter; when omitted the API automatically selects the first active order on your account. Use `GET /mail` to list all orders, and `GET /mail/{id}` to inspect a single order including its current SMTP password. # Sending Email Three sending methods are available depending on your use-case: | Endpoint | Best for | |----------|----------| | `POST /mail/send` | Simple single-recipient messages | | `POST /mail/advsend` | Multiple recipients, CC/BCC, attachments, named contacts | | `POST /mail/rawsend` | Pre-built RFC 822 messages (e.g. DKIM-signed payloads) | After a successful send each endpoint returns a `GenericResponse` whose `text` field contains the **transaction ID** assigned by the relay. This ID can later be matched against entries in `GET /mail/log` via the `mailid` query parameter. # Filtering & Logs `GET /mail/log` provides paginated access to every message accepted by the relay for your account. Combine any of the query parameters to narrow results — e.g. `from`, `to`, `subject`, `messageId`, `origin`, `mx`, `startDate`/`endDate`, and `delivered`. # Blocking Two independent mechanisms exist for suppressing unwanted email: - **Block lists** (`GET /mail/blocks`, `POST /mail/blocks/delete`) — addresses flagged by the system spam filters (LOCAL_BL_RCPT / MBTRAP rules in rspamd, and suspicious subjects). - **Deny rules** (`GET /mail/rules`, `POST /mail/rules`, `DELETE /mail/rules/{ruleId}`) — custom rules you configure to reject specific senders, domains, destination addresses, or subject-line prefixes before a message is even attempted. # Authentication In order to use most of the API calls you must pass credentials from the [my.interserver.net](https://my.interserver.net/) site. We support several different authentication methods but the preferred method is to use the **API Key** which you can get from the [Account Security](https://my.interserver.net/account_security) page. Pass your key in the `X-API-KEY` HTTP request header for every protected call.
