v28.2

Release 28.2

Postmark Message Stream Support

Postmark integrations now support configurable Message Streams, allowing a single Postmark account to be used for both transactional (outbound) and broadcast/marketing emails. The stream ID can be set in workspace integration settings.

Contacts API: Partial Email Search (#292)

The /api/contacts.list endpoint now accepts partial email strings in the email filter parameter. Previously, the API rejected anything that wasn't a fully-formed email address with a 400 - invalid email format error, even though the underlying query already supported ILIKE partial matching. You can now search by domain (@company.com), username prefix, or any substring.

Broadcasts: MJML Code Mode Fix

Fixed MJML code mode templates failing with "template missing content" error when sending broadcasts. Templates created with the MJML code editor now send correctly.

v28.1

Notifuse v28.1 — Release Notes

---

What's New

Transactional Emails — Dynamic Preheader Text

Added subject_preview override to email_options, allowing dynamic email preheader text per API call with Liquid templating support.

Templates — Language Selection for Test & Preview

Added language selection to the "Send Test Email" modal and "Preview Template" drawer, allowing users to preview and test translated email variants.

Demo — Multi-Language Email Templates

The demo workspace now includes French and Spanish translations for all 4 email templates, showcasing the multi-language feature.

Email Builder — mj-liquid Block

Added the mj-liquid block type for embedding raw MJML+Liquid code in the visual editor. This enables dynamic structural content like for-loops generating columns or conditional sections.

Improvements

• Templates: Downloaded template files now use the template's name as filename instead of a generic name (#286)

Security

• Upgraded liquidjs to 10.25.0

v28.0

Notifuse v28.0 Release Notes

What's New

Visual or MJML — You Choose

When creating a new email template, you can now pick between the visual drag-and-drop builder or the MJML code editor. Use whichever workflow fits the task.

Template Translation

Email templates can now be translated into every language configured in your workspace settings, making it easier to run multi-language campaigns from a single template.

Configurable SMTP EHLO Hostname

Some SMTP servers reject the default EHLO localhost greeting. You can now set a custom EHLO hostname (e.g. your own domain) via:

• The SMTP_EHLO_HOSTNAME environment variable
• The setup wizard
• Workspace integration settings

When left empty, the hostname defaults to the SMTP host value.

---

Bug Fixes

• Contacts — Removed the invalid "Blacklisted" status from the change-status dropdown and replaced it with the correct "Bounced" and "Complained" options.
• Transactional Notifications — Delivery stats (sent, delivered, failed, bounced) were always showing 0. Messages are now linked to their originating notification via a new transactional_notification_id column.
• Email Builder — <mj-attributes> global styles now apply correctly in both preview and sent emails.

---

Upgrade Notes

This release includes a workspace database migration that adds a transactional_notification_id column to the message history table. The migration runs automatically on startup and is backward-compatible.

No manual action is required.

v27.4

• Notification Center: Fixed browser language auto-save overwriting contact's manually chosen language. Now only auto-detects when contact has no language set.

• Transactional Emails: Added subject override to email_options, allowing dynamic email subject lines per API call with Liquid templating support (#281)

v27.3

• Segments: Added template filter to email activity conditions, allowing segments like "opened template X at least 3 times"
• SMTP: Fixed TLS override option not working for system emails (magic codes, invitations, alerts). The "Use TLS" toggle was ignored, causing certificate errors on local SMTP relays (#275)
• Automations: Fixed automation emails rendering {{ notification_center_url }} and {{ unsubscribe_url }} as empty strings by using the shared template data builder (#279)
• Segments: Fixed race condition where background task execution could pick up unrelated tasks, causing flaky segment recompute behavior
• Security: Upgraded rollup to 4.59.0 and minimatch to 10.2.4
