Subscriber Lists

Grow your audience automatically

Lattia includes a built-in email subscription system. Supporters can subscribe through embeddable forms on your website, through your storefront, or through the subscription API. Every subscriber is captured with their email, first name, last name, and the source of their signup — so you know exactly where your audience growth is coming from.

The subscriber list is separate from your imported contacts and your donor database. It represents people who've actively opted in to receive email from your organization — your most engaged and permission-based audience.

Subscriber dashboard

The subscriber management screen gives you four key stats at a glance: total active subscribers, new subscribers this month, unsubscribed count, and converted subscribers (people who subscribed and later made a donation or purchase). Search by name or email, filter by status (active, unsubscribed, or all), and manage your list from one screen.

Embeddable subscription API

Lattia provides a public API endpoint for each organization that accepts subscription requests. Point any form on any website at your endpoint and new subscribers appear in your list automatically. The API handles CORS, duplicate detection, and validation — you just need a form that submits an email address.

Automatic unsubscribe handling

When a subscriber clicks the unsubscribe link in any email, they're immediately removed from the active list and their status is updated to "unsubscribed." They can also provide an optional reason for leaving. Unsubscribed addresses are permanently excluded from future sends — no manual cleanup, no accidental re-sends.

Ready-made email audience

Your subscriber list is available as a targeting option every time you create an email campaign. Select "All Subscribers" and you're sending to everyone who's opted in. Combined with imported contact lists and donation page audiences, you have flexible segmentation without needing a separate email marketing platform.
