Mautic Plugin: Resend to Non-Openers

A Mautic plugin that adds a one-click "Resend to Non-Openers" action for segment (broadcast) emails.

After a segment email has been sent, this plugin lets you resend it to contacts who did not open it. It automates the manual workflow of cloning the segment with a "not read email" filter, cloning the email (including all its translations), and publishing it for the broadcast cron to send.

Why

Every major email marketing platform (Mailchimp, Brevo, ActiveCampaign) has a one-click resend-to-non-openers feature. In Mautic it previously required a tedious manual workflow. Mailchimp data from 1,300 resend campaigns shows resends add +8.7 percentage points to the original open rate (from a 26.7% average) — it's one of the highest-ROI email actions.

Features

• One-click resend from the email detail page (Options dropdown → "Resend to Non-Openers")
• CLI command for automation: bin/console mautic:emails:resend-nonopeners <email-id> [--dry-run]
• API endpoint: POST /api/resend-nonopeners/{id}
• Multilingual support — clones parent email and all translation children, filters across all translation IDs
• Automatic segment creation — new segment combines "member of original audience" + "did not read email" filters
• Auto-categorization — creates a "Resend Non-Openers" category and assigns it to all cloned emails and segments for easy filtering in lists
• Auto-cleanup — when the resend email finishes sending (or is manually unpublished), the linked segment is automatically unpublished too
• Safe by default — each email can only be resent once; a resend cannot be resent again
• Fully async — the HTTP request returns immediately; segment rebuild and delivery happen in the background via Mautic's standard crons, so it works for segments of any size without timeouts
• Uses the standard broadcast cron — scales to any list size, respects rate limits

How it works

1. You click "Resend to Non-Openers" on a sent segment email
2. The plugin creates a new segment with two filters:
   • Segment Membership — including any of — [original segment(s)]
   • Read a specific email — excluding any of — [original + all translations]
3. The plugin clones the email and all its translation children, assigns them to the new segment, and publishes them
4. Both the segment and the cloned emails are tagged with a "Resend Non-Openers" category (auto-created on first use)
5. A record of the resend is stored in the email_resends table so the email can't be resent again
6. The HTTP request returns immediately — everything from here is async via Mautic's standard crons
7. mautic:segments:update rebuilds the new segment to populate the non-opener contacts
8. mautic:broadcasts:send picks up the cloned email and sends it to the non-openers
9. When all non-openers have been sent to, Mautic auto-unpublishes the resend email
10. The plugin detects the unpublish and automatically unpublishes the linked segment too — no cleanup needed

Requirements

• Mautic 7.0 or newer
• PHP 8.2+

Installation

Via Composer (recommended)

The plugin is published on Packagist. If your Mautic installation has a composer.json (source-based install), run:

Composer reads install-directory-name from the plugin's composer.json and installs it to plugins/MauticResendNonOpenersBundle/ automatically.

Manual installation (for runtime Docker images)

The official mautic/mautic:7-apache Docker image is a runtime build without composer.json, so composer require will not work inside it. In that case, clone the plugin directly into the plugins directory and pin a tag for reproducible builds:

For Dockerfile usage, add the same commands as a RUN step. To upgrade, bump the tag and rebuild.

The plugin creates an email_resends table automatically from its entity metadata during plugin reload.

Usage

UI

1. Open a segment email that has been sent to at least one contact
2. Click the Options dropdown (the chevron next to the Edit button)
3. Click Resend to Non-Openers
4. Confirm in the modal
5. The broadcast cron will send the cloned email to non-openers on its next run

Note on continuous-sending emails: if the original email has "continue sending" enabled, "non-openers" will include very recent recipients. The plugin still allows the resend — the decision of when to trigger it is up to you.

API

Response:

Constraints

• Only segment (broadcast) emails can be resent — not template/campaign emails
• The original email must have been sent to at least one contact (sentCount > 0). This includes emails with "continue sending" enabled, since those never reach sendingStatus === 'sent' despite having real non-openers to target.
• Each email can only be resent once
• A resend email cannot be resent again
• Triggering from a translation child automatically resolves to the parent
• Permission check: requires email:emails:editown or email:emails:editother

Technical approach

The plugin is implemented without any modifications to Mautic core:

• No core entity changes — a plugin-owned EmailResend entity stores the relationship between an original email and its resend, instead of a column on the emails table
• No template modifications — the UI button is injected via the CoreEvents::VIEW_INJECT_CUSTOM_BUTTONS event
• Leverages existing Mautic primitives — uses the lead_email_received segment filter (with "excluding any of" operator) and the leadlist membership filter; no custom SQL
• Standard broadcast pipeline — the cloned email is published and picked up by mautic:broadcasts:send like any other segment email
