Mailster’s Time Frame settings allow you to control when email campaigns and autoresponders are sent, enhancing engagement and respecting recipients’ schedules. Customize sending days, times, and time zones to optimize delivery, while ensuring transactional emails are sent immediately, regardless of these settings.
Mailster’s Security Settings enhance campaign protection by validating emails, blocking spam, and preventing duplicate signups. Key features include MX record checks, SMTP validation, honeypots for bots, antiflood controls, and options to block disposable emails, specific addresses, domains, IPs, and countries while allowing safe domains.
Mailster includes a List Unsubscribe Header in newsletter campaigns, facilitating easy opt-outs through mailto or URL links. This feature enhances user experience, boosts email deliverability, and ensures compliance with anti-spam regulations. Major email clients like Gmail and Apple Mail support this header, providing clear unsubscribe options for recipients.
Mailster empowers WordPress users by providing customizable role-based access to manage campaigns, subscribers, and templates. With default roles like Administrator and Editor, you can define specific capabilities using plugins like “User Role Editor.” This ensures control over who can create, edit, or send campaigns efficiently.
Mailster offers three static map options: no maps, OpenStreetMaps for privacy, or Google Maps for high-quality visuals. Adjust your preference in Settings => General. Note that Google Maps requires an API key and may have display restrictions in emails. Choose the option that best fits your needs.
When starting with email marketing or changing providers, avoid sending too many emails at once. Use Mailster’s Warmup settings to gradually increase your email throughput. Set a timeframe for warming up your server, allowing Mailster to adjust send rates and batch sizes over time for optimal delivery.
Mailster sends emails in batches to avoid server timeouts and delivery bans. You can enable automatic batch size adjustment based on your server’s capabilities. However, be cautious of your email provider’s limits, as this option prevents manual size settings and may require time to optimize batch delivery.
Email spam filters may click links in your emails, leading to false open rates and unintended unsubscribes. Mailster offers an “Auto Click Prevention” option to counter this. By redirecting link clicks through a proxy page, it ensures accurate user engagement metrics while safeguarding against bot interference.
Optimize your email marketing by balancing throughput rate and batch size to avoid server timeouts. Determine your server’s email capacity and adjust your cron interval for efficient sending. For instance, sending 20 emails every 5 minutes allows for 240 emails per hour, while 40 doubles that to 480.
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.
With Mailster 4.0, usage tracking is optional during installation or updates. Opting in helps us improve features and fix bugs. Data collected includes site details and Mailster settings, but we never share this information. You can enable or disable tracking anytime in the settings.
To automatically manage bounces in Mailster using SendGrid, install the SendGrid Integration plugin. Choose SendGrid on the delivery tab to mark future bounces automatically. For Mailster, request SendGrid Support to enable the “preserve headers” option; otherwise, it will overwrite your return-path. Note that the WEB API is incompatible with Mailster’s bounce handling.
To enhance Mailster’s email delivery rates, consider reducing the cron interval, increasing the number of emails sent at once, or selecting a different delivery method. Remember, delivery speed averages 1-2 emails per second, and server capacity and connection quality can impact performance.
Mailster allows you to enhance email delivery by overriding the default wp_mail function. Choose from three settings: bypass Mailster, use it for all emails, or apply a template. Additionally, control how Mailster interacts with third-party content types, ensuring compatibility and effective email delivery.
Mailster requires a cron job to send campaigns. Check its status under Newsletter > Settings > Cron, where you can see the last trigger time and details. If the cron hasn’t run recently, verify your cron settings and ensure the secret hash hasn’t changed.
Using GoDaddy’s email servers is possible but comes with restrictions. Limit your SMTP sends to 500 emails per account, ensure your from and reply-to addresses match your domain, and configure settings with the specified server details. Be mindful of additional limitations that may apply.
