REST HTTP API
You can send email using the REST HTTP endpoint. This allows you to send a single message or a batch of messages in a single API call.
SMTP is not an API, but a protocol used to inject email. Delivery details of each message can be customized by adding X-headers. You can create authorized users for SMTP sending through the API. Multiple SMTP servers can be configured.
Pipe email into a Linux command-line program from the same server as your GreenArrow install. GreenArrow provides programs compatible with both sendmail and qmail. This is not an HTTP API, but a standard, well-documented interface for injecting email.
Marketing Studio Campaigns
GreenArrow Studio’s API has endpoints to schedule email campaigns and create automatically triggered autoresponders. Autoresponders can be triggered by an API endpoint and can contain additional replacement data, which together provide a triggered email template feature.
Marketing Studio Subscribers APIs
GreenArrow Marketing Studio’s API provides the ability to manage subscribers, mailing lists, custom fields, segmentation criteria, suppression lists, and list segments. You can fire off bulk subscriber imports and check on their status.
Instead of importing subscribers, you can use GreenArrow Studio’s Remote Lists feature to your remote database, run an SQL query, and get a custom subscriber list for each campaign. This can be scheduled through the API.
Email Delivery Control APIs
Automatically respond to changing delivery conditions through Dynamic Delivery throttle programs. Intelligently split mail over multiple IP addresses using VirtualMTAs, and hand email off to other SMTP servers with Relay Servers.
ESP Management APIs
Email Service Providers who deploy GreenArrow Marketing Studio for their users are able to manage customer accounts and manage user accounts. They can set customer permissions, subscriber quotas, and sending quotas through the organization API. For billing and management they can get email volume and subscriber counts for a customer account and a list of all campaigns from all customer accounts.
