## Automation Branching
If you've been creating separate automations just to send different emails to different segments, that's no longer necessary. Branching is now live in AutoSend. One automation, multiple paths.
#### Branch by contact property
Split any automation into branches based on contact properties. Each branch gets its own filters, wait times, and email sequence.
For example, a new contact gets added to your list. Instead of sending everyone the same onboarding sequence, you branch based on their plan:
* Trial users get a sequence focused on activation and conversion
* Pro users get tips on getting the most out of their plan
* Business users get a white-glove onboarding with dedicated support info
#### Automations API
We also opened up API endpoints for Automations, so you can create and manage automations programmatically. List, create, get, update, pause, resume, and delete automations directly from your code.
Read the Email Automations documentation to learn more about branching, and check the Automations API reference to start managing automations programmatically.
## RBAC and Projects API
Two big additions to multi-project support: role-based access control for your team and a full Projects API.
#### Role-Based Access Control
Team permissions now have two distinct roles: **Admin** and **Member**.
* **Admins** have full access to the entire workspace, including all projects, domains, billing, and member management.
* **Members** have scoped access. Admins assign them to specific projects, and they can only see and operate within those projects. Members can also add or remove other members within their assigned projects.
Read the Team documentation for the full invite flow and FAQ.
#### Projects API
You can now manage projects programmatically using the Account Admin API key (`ASA_` prefix). Three endpoints are available:
* **List Projects** - Retrieve all projects in your organization.
* **Create Project** - Create a new project with a name. The project is ready to use immediately.
* **Delete Project** - Permanently delete a project and all its associated resources. This cannot be undone.
Check out the Projects API reference to get started.
## 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 an `x-project-id` header to specify the target project, except when creating a new project.
Read the Projects documentation to learn more, and the API Keys documentation for details on key types and authentication.
## NEW: 41 API Endpoints Added to API Reference
The API reference just got a major expansion. Seven new endpoint groups are now fully documented, covering everything from campaign management to domain configuration.
#### Here's what's new:
* **Custom Fields** (4 endpoints) - List, get by name, create, and delete custom contact fields for flexible segmentation.
* **Templates** (5 endpoints) - Get, create, update, delete, and search email templates programmatically.
* **Senders** (4 endpoints) - List, get, create, and delete verified sender identities.
* **Campaigns** (8 endpoints) - Full campaign lifecycle management: list, get, create, update, pause, resume, abort, and delete.
* **Domains** (5 endpoints) - List, get, add, verify, and delete sending domains.
* **Contact Lists** (7 endpoints) - List, get, create, and delete lists, plus get contacts, bulk add, and remove contacts.
* **Suppression Groups** (8 endpoints) - List, get, create, update, and delete groups, plus search entries, bulk suppress, and bulk unsuppress.
All endpoints include request/response examples in multiple languages. Check out the API Reference to get started.
## 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., `verified` equals `true`). 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., `published` changes from `unpublished` to `published`). Perfect for reacting to real-time changes. Supports multiple conditions with AND/OR logic.
#### Brand new visual workflow builder
Build your automation sequences in a completely redesigned visual workflow builder with a cleaner interface and smoother experience. Do try the email drag-n-drop to rearrange emails in your sequence. That's our favorite part.
Read the updated Email Automations documentation to learn more.
## NEW: AutoSend MCP Server is here.
You can now manage your email campaigns, templates, contacts, and senders directly from AI assistants.
The **AutoSend MCP Server** connects to AI tools like Claude, Cursor, Codex, Antigravity, etc using the Model Context Protocol. Just authenticate with OAuth (no API keys to manage), and your AI assistant gets secure access to your AutoSend project.
It ships with **17 tools** across 5 categories: Lists & Segments, Templates, Senders, Suppression Groups, and Campaigns. Create drafts, search templates, duplicate campaigns, and more, all through natural language.
Check out the MCP Server documentation to get started.
## NEW: Domain warmup is now built into AutoSend.
If you've ever started sending on a new domain and wondered why your open rates were tanking, this is for you.
We just shipped **Gradual Send**. It's a new sending mode that automatically ramps up your email volume over time, so mailbox providers get familiar with you before you hit them with your full list.
You pick a starting volume, choose how fast you want to grow, set a start date, and that's it. AutoSend builds out your daily send schedule and shows you a chart of exactly what will go out and when. If your bounce or complaint rate spikes, it pauses automatically.
No manual scheduling. No spreadsheets. No sending five small campaigns just to warm up a domain.
You'll find it under "When to send?" the next time you set up a campaign. Highly recommend it if you're on a new domain or sending to a cold list for the first time.
Read our Domain Warmup guide to learn more about warming up your domain and improving deliverability.
## Quick Create Menu and Performance Improvements
We shipped quality-of-life improvements this week. Faster workflows, cleaner analytics, and a few important fixes.
#### Quick Create Menu
Create campaigns and automations directly from the dashboard. Click the "+" button in the top right corner without navigating away from your current page.
#### Faster Campaign and Analytics Loading
Dashboards load faster with caching for workflow analytics and streamlined campaign queries. Separated worker services for email sending, validation, and webhooks handle higher loads independently. Lazy loading for past and failed campaigns reduces initial page load times.
### Fixes:
* Fixed invited users being redirected to the welcome screen instead of their team's workspace
* Resolved analytics text alignment issues that made numbers hard to read
* Added SMTP rate limiting API to prevent sending spikes and improve deliverability
## Dashboard Redesign and Landing Page Refresh
The dashboard has been redesigned from the ground up and a fresh new landing page has launched.
#### Dashboard Redesign
Your dashboard now surfaces key metrics (sends, opens, clicks, bounces), active campaigns, and product updates right when you log in. No more digging through reports.
#### Fresh Landing Page
Completely redesigned with a modern look, interactive sections, smoother animations, and a clearer story about how AutoSend helps you send better emails.
#### Faster CSV Imports
Importing large contact lists is significantly faster. Upload your CSV and get back to work.
#### User ID Support in CSV Imports
Import user IDs alongside contact data to maintain consistent identifiers across systems.
#### List-Unsubscribe Header
The standard `List-Unsubscribe` header is now included in all emails, enabling one-click unsubscribe buttons in Gmail and Apple Mail. No configuration needed.
### Fixes:
* Fixed campaign analytics not refreshing when switching between campaigns
* Resolved dark mode styling issues with the payment alert banner
* Improved link formatting in the email builder
## CC and BCC Support
Native CC and BCC support is now available across AutoSend.
#### Send to Multiple Recipients
Add CC and BCC recipients to any email via API or SMTP relay without sending separate emails.
#### Full Email Activity Tracking
Every CC and BCC recipient is tracked individually. See opens, clicks, bounces, and complaints for each recipient separately.
#### Smart Suppression Handling
When a TO recipient is suppressed, CC and BCC recipients are automatically suppressed too. Bypass options are available when needed.
#### Proper Bounce and Complaint Attribution
Bounces and complaints from CC/BCC recipients are correctly attributed to the right email address.
#### Cleaner Campaign Dashboard
Active campaigns now automatically appear at the top and past campaigns are hidden to reduce visual clutter.
#### Filter Contacts by List ID
Added `contactListId` parameter to the contacts API for filtering contacts by specific lists.
#### Bypass Suppressions
Send an email to a suppressed recipient on a per-email basis for critical communications like password resets.
### Fixes:
* Fixed proration calculations for plan upgrades and downgrades
* Resolved issues with payment cancellations not reflecting correctly
* Fixed billing cycle date updates after plan changes
