Introducing Projects
You can now create multiple Projects under a single AutoSend account. Each project is a fully isolated workspace with its own API keys, contacts, senders, templates, campaigns, automations, and webhooks. Your subscription and monthly email quota are shared across all projects.
Why Projects?
- Keep Production, Staging, and Development environments completely separate
- Run multiple independent products under one subscription and billing
- Build multi-tenant platforms (CRMs, Shopify apps, marketing tools) where each customer gets their own isolated project
- Manage multiple clients as an agency without any data mixing
Two types of API Keys:
Along with Projects, we’re introducing a second API key type:- Project API Key (
AS_...): Scoped to a single project. Use this for sending emails, managing contacts, templates, and campaigns. The right key for most integrations. - Account API Key (
ASA_...): Cross-project scope. Use this to programmatically create, update, or delete projects. All requests with an Account API Key require anx-project-idheader to specify the target project, except when creating a new project.

Email Automations v2.0: New Trigger Types + Visual Builder
Email automations just got a lot more powerful. You can now trigger automations based on contact properties, not just list or segment membership.
Three Trigger Types:
- New contact is added to: Trigger when a contact joins a specific list or segment. Same as before.
- Contact property matches with: Trigger when a contact’s property matches a condition you define (e.g.,
verifiedequalstrue). Great for targeting contacts based on their current state. - Contact property changes from → to: Trigger when a contact’s property transitions from one value to another (e.g.,
publishedchanges fromunpublishedtopublished). Perfect for reacting to real-time changes. Supports multiple conditions with AND/OR logic.
