Subscribers & forms

Subscribers live in your own WordPress database — no third-party CRM, no external sync required. Manage them under Newsletter → Subscribers.

The subscriber list

• Filter by status (active, unsubscribed, bounced) and by type (free, paid).
• Search by email or first name.
• Export CSV — pulls every subscriber matching your current filter, with email, name, status, type, joined date. Useful for backups and migrations.

How signups work under the hood

When someone submits a signup form, the plugin:

1. Validates the email server-side.
2. Inserts a row in wp_otts_subscribers with a 64-character random token.
3. Fires the otts_subscriber_created action — used by the welcome email and lead-magnet handlers.
4. Returns success to the form’s JavaScript, which renders the success message.

One-click unsubscribe

Every email has an unsubscribe link in the footer — clicking it requires no login. The link encodes the subscriber’s email + their token; the REST endpoint verifies both before flipping the row to unsubscribed. GDPR-clean.

Inline signup form

Newsletter → Signup Forms — visual builder with live preview. Set headline, subheadline, placeholder, button label, colours, border radius, GDPR consent checkbox, success message. Save.

Cache-safe

The form does not use a WordPress nonce. Nonces break under page caching (cached HTML = stale nonce). Spam protection is a hidden honeypot field — bots fill every input and get silently dropped, humans never see the field. Works under any cache plugin.

Popup and slide-in forms (pro)

The pro plugin adds two more form types: a centred popup (defaults: shows after 15 seconds) and a slide-in from the bottom-right (defaults: shows at 50% scroll depth). Both use a session-scoped cookie so the same visitor only sees them once. Set the type to Popup or Slide-in in the form editor.

Next: Welcome email & lead magnet.
