Trigger Custom Javascript on Form Submission
Mailster Block Forms allows you to run custom JavaScript to track form submissions via Analytics. Access the “Events” section to define your code for five event types: Impression, Open, Close, Submit, and Error. Each event provides specific context and allows you to send data to Google Analytics or Plausible.
Manually replacing a Mailster version
Mailster includes security features to protect against malicious versions. To ensure you have a legitimate copy, obtain a valid license from EverPress, replace the plugin on your website, and register your purchase code in the Mailster Dashboard. Follow these steps to maintain a secure installation.
The Mailster Cookie
Mailster sets a cookie named “mailster” when a subscriber clicks a campaign link, allowing user identification even without an account or login. This cookie expires one hour after the last click but can be extended. It’s generated using PHP’s setcookie method, not JavaScript.
List Based and Global Subscriptions
Mailster offers two subscription models: list-based (recommended for flexibility) and global subscriptions. Subscribers can unsubscribe from individual lists or all at once. Only those with a “subscribed” status receive campaigns, ensuring tailored communication based on user preferences. Adjust subscription types easily in the settings.

User Ratings
Mailster’s user ratings reflect subscriber engagement, updated with each interaction—opens and clicks boost ratings, while bounces and unsubscribes lower them. Ratings, ranging from 10% to 100%, prioritize sending campaigns to higher-rated subscribers. You can also segment lists based on ratings and customize them programmatically.
Adding Posts to your Campaign
Mailster offers seamless integration with WordPress, allowing users to easily add posts, pages, or custom post types to campaigns. You can include static content, which remains unchanged, or dynamic content that updates upon sending. Customize your campaigns with filters for tailored content display.
Setup Automatic Bounce Handling
Mailster automates bounce processing with proper setup. Assign a dedicated bounce address, enter server credentials, and define bounce check options. Soft bounces are retried while hard bounces result in immediate subscriber removal. Regularly test your settings to ensure functionality and maintain a clear postbox.

What is a Cron Lock?
Mailster prevents duplicate emails by creating a cron lock during campaign processing. If a lock is active, you’ll see a notification when accessing the cron URL. Locks are released automatically after processing, but may require manual release if a timeout or error occurs. Adjust email volume if you frequently encounter locks.
Why does support expire?
Since September 2015, Envato offers 6 months of included support for purchases. Support can be renewed on the item page, but expired support does not guarantee a response for tickets submitted post-June 2016. Users can reply to tickets for 14 days after expiration; new tickets require active licenses.
Why is my WordPress version no longer supported?
WordPress updates introduce new features and bug fixes. While plugins that worked previously will likely continue to function, unsupported versions may encounter errors. It’s essential to keep your site and plugins updated to avoid security vulnerabilities.
How does tracking in Mailster work?
Mailster enables tracking of opens, clicks, unsubscribes, and bounces. It counts opens via a small image loaded from your server; however, some email clients block this image. Clicks are tracked as unique or total, with rates displayed for Click-Through Rate (CTR) and Adjusted Click-Through Rate (ACTR).
Choosing your Delivery Method
Mailster offers two default delivery methods: Simple SMTP and SMTP. Simple SMTP is not recommended for bulk mailing due to provider limits. For larger subscriber lists, use SMTP and check with your host for credentials. Additional methods like AmazonSES, SparkPost, Mailgun, SendGrid, and Gmail can be added via plugins.
How can I manually upload Mailster templates?
Upload templates via FTP if the Templates section isn’t suitable. Extract your downloaded archive and place the folder in “wp-content/uploads/mailster/templates” (note: “wp-content” may have a different name). Your template will be available under Newsletter > Templates, with images generated automatically.
How colors work with the Mailster Editor?
Colors in the Mailster Editor are determined by the template’s HTML and only recognize 6-digit hex codes (e.g., #FFFFFF). Short hex codes are ignored. When merging colors, use slightly different shades to ensure Mailster can distinguish between them, preventing unintended uniformity.
How can I setup the newsletter homepage (legacy)?
Mailster requires a static newsletter homepage for subscription management. This page, accessible at http://yourdomain.tld/newsletter-signup, utilizes essential shortcodes for signups, confirmations, and unsubscriptions. Customize your content within the [newsletter_signup] shortcodes, and remember to link it in your settings. Subpages for unsubscribe and profile are also available.
Can I add attachments to my newsletter?
Enhance your campaigns by adding attachments via the campaign edit screen, with a total size limit of 1MB (modifiable to 5MB using a filter hook). Be cautious, as large attachments may lead to delivery issues. Consider providing download links for subscribers instead.
How can I open the browsers console?
The Browser Console is essential for tracking JavaScript errors and server-related information. Access it in Chrome (CTRL + SHIFT + J), Safari (CTRL + ALT + I), IE9 (F12), Firefox (CTRL + SHIFT + K), or Opera (CTRL + SHIFT + I) to troubleshoot effectively.
How can I setup a cron job?
Ensure your email campaigns are sent correctly by properly setting up your cron. You can use WP-cron for automatic scheduling or opt for a real cron job for more control. Check your host’s guidelines for setup and troubleshooting to ensure smooth operation.
What is the CAN-SPAM act and do my newsletters have to comply?
The CAN-SPAM Act of 2003, signed by President Bush, established national standards for commercial email in the U.S. It mandates compliance to prevent legal issues with newsletters. Similar laws exist globally, including Canada’s CASL and Australia’s Spam Act, ensuring email marketing adheres to specific regulations.
How do I export my subscribers?
Easily export your subscribers from the “Manage Subscribers” page by selecting the “Export” tab. Choose your lists, set conditions, and specify the status to filter your audience. Define the fields and their order, then export as an Excel or CSV file, with settings saved for future use.
Where’s my purchase code?
To find your Mailster Newsletter Plugin license code from the Envato Marketplace, log in, go to “Downloads,” select the plugin, and click the License certificate link. If purchased directly from our website, manage your licenses through our site for easier access.
