Ensure your emails reach the inbox with best practices and technical guidance found in the Deliverability section. Learn how to authenticate your domain with SPF, DKIM, and DMARC, manage bounce handling, avoid spam filters, and monitor your sender reputation. This category helps you optimize every aspect of email delivery to improve open rates and maintain trust with your audience.
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 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.
Mailster’s email delivery relies on your sending server’s response, but a “success” message doesn’t guarantee inbox delivery. Emails may end up in spam, bounce back, or face delays. Use Mailster’s Email Health Check to assess deliverability and consider changing delivery methods or servers if issues persist.
Mailster offers unlimited subscribers, lists, forms, and campaigns, but server limits may affect performance. To optimize, maintain fewer subscribers, simplify custom fields, and reduce autoresponder complexity. For best results, use PHP 7.4+, at least 128MB memory, and consider a dedicated server or VPS.
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.
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 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’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 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.
DKIM (DomainKeys Identified Mail) links a domain to an email, ensuring authenticity. To enable DKIM, add a TXT record with your public key. Email programs sign messages with a private key, allowing receivers to verify authenticity. Proper setup shows a green indicator, while updates may take up to 48 hours.
To avoid spam filters in email campaigns, conduct a spam score test, use a dedicated Email Service Provider (ESP), and authenticate emails with DKIM and SPF. Encourage users to whitelist your address, avoid spammy words, and only send to subscribed users. Follow legal guidelines and utilize Mailster’s precheck feature for improvements.
Your provider restricts bulk and outgoing mail. Consider using dedicated email services like SendGrid, Mandrill, Amazon SES, or SparkPost. If Mailster lacks a specific add-on, you can revert to SMTP. Explore free WordPress plugins for various delivery methods.
Mailster allows you to customize email sending rates to comply with your provider’s limits, typically 1-2 emails per second. Customers can achieve up to 12 emails per second. Avoid sending over 200 emails simultaneously to prevent server timeouts. Always check your provider’s specific sending limits.
