MailerPress Integration

2 min readUpdated April 20, 2026

MailerPress is a self-hosted email marketing plugin for WordPress that provides newsletter and list management directly from your WordPress admin. Because MailerPress runs directly on your WordPress site, WP Smart Consent integrates with it via MailerPress’s native PHP API — no external API key or internet connection required.

What You’ll Need#

MailerPress installed and active on the same WordPress site as WP Smart Consent. No API key or account setup is needed beyond that.

Setting It Up#

In the WP Smart Consent dashboard, go to Integrations and find the MailerPress card. Enable it and save. WP Smart Consent will detect MailerPress automatically and begin forwarding opted-in contacts as soon as the integration is active.

What Gets Sent#

When a visitor opts in, WP Smart Consent forwards their first name, last name, and email address to MailerPress via add_mailerpress_contact(). The contact is added to your MailerPress contacts list immediately. If the contact already exists, their record is updated rather than duplicated.

List Assignment#

By default, contacts are added to your default MailerPress list. If you need to assign subscribers to a specific list, this can be controlled programmatically using the wpsc_mailerpress_list_id filter.

Works Alongside Other Integrations#

Enabling the MailerPress integration doesn’t affect any of your other active integrations. Each destination is independent — a single opt-in event will be forwarded to MailerPress and every other enabled destination simultaneously, and logged with the source integration that captured it.
