Postalion – Newsletters and Email Subscribers

Postalion is a newsletter plugin that runs entirely on your own site. It collects subscribers, sends your newsletters in the background and keeps a record of every email. Your list stays in your WordPress database and the mail goes out through wp_mail(), so it uses whatever SMTP plugin or mail service you already have.

There are no limits on subscribers or on how often you send, no account to create, and the plugin makes no requests to outside servers.

Write

• Newsletter composer with five email templates: Classic, Letter, Bulletin, Announcement and Card
• Content blocks made for email: headline, button, two columns, image and text, note, divider, spacer, social links
• Personalisation: subscriber name and email, site name and address
• Preview for desktop and phone, and a test email to yourself
• The templates show your site logo, or the site name when there is no logo

Send

• Background sending in batches: the first batch goes out at once, the rest through WP-Cron
• Batch size and pause between batches are yours to set (default: 10 emails every 5 seconds)
• Send now, or schedule a date and time
• Live progress, with stop and resume
• An interrupted send continues where it stopped; nobody gets the same email twice

Grow

• Sign-up form by shortcode, with double opt-in
• CSV import and export
• The users of your site are subscribers too, and can opt out from their profile
• Search, filters and bulk actions

Keep track

• Email log: every email with its recipient, date and result, and a preview of the email as that person received it
• Activity log: sign-ups, confirmations, unsubscribes, imports and sends
• System log for errors and warnings
• Log entries are deleted automatically after a period you choose (90 days by default)

Respect

• Unsubscribe link in every email, plus one-click unsubscribe for mail clients that support it (List-Unsubscribe-Post)
• No tracking pixels and no rewritten links
• Supports the WordPress tools for exporting and erasing personal data
• No telemetry and no external requests

Shortcodes

• [postalion_form] – sign-up form. Attributes: title, description, button_text, show_name="false", class.
• [postalion_unsubscribe] – unsubscribe form.
• [postalion_subscriber_count] – number of people on your list.
