## Capabilities

AutoSend can:

- Send transactional emails (OTPs, password resets, receipts, alerts, notifications)
- Send marketing campaigns (newsletters, announcements, promotions)
- Run email automation workflows (drip sequences, triggered emails)
- Manage contacts, lists, and segments
- Manage unsubscribe groups
- Warm up new sending domains gradually (Gradual Send / Domain Warmup)
- Validate and suppress invalid email addresses automatically
- Track delivery events via webhooks (sent, delivered, bounced, opened, clicked)
- Authenticate sending domains with SPF, DKIM, and DMARC
- Provide analytics on opens, clicks, bounces, and complaints
- Receive inbound email via API — parse, read, download attachments, and reply programmatically

## Getting Started

1. Sign up at [autosend.com](https://autosend.com)
2. Verify your sending domain (add SPF, DKIM, and DMARC DNS records provided in the dashboard)
3. Integrate via API, SMTP, or agent skills
4. Start sending emails

Typical integration time: Under 30 minutes.

### Domain Authentication

After adding a domain, AutoSend provides three DNS records to add:

- **SPF**: A TXT record authorizing AutoSend to send on your behalf
- **DKIM**: A CNAME record for cryptographic email signing
- **DMARC**: A TXT record defining your domain's email authentication policy

All three must pass verification before sending is enabled. AutoSend checks DNS propagation automatically and notifies you when verification succeeds.

### Gradual Send (Domain Warmup)

New sending domains start with low reputation. Gradual Send automatically ramps up your sending volume over time to build trust with inbox providers. Instead of sending a full campaign on day one, AutoSend distributes delivery across a warmup schedule. This is available on Growth and Scale plans and can be enabled per domain.
