MailerQ is not only fast and flexible, but also the perfect on-premise solution for email delivery software.
Many email solutions require you to send your customer data to third parties. Install & configure MailerQ on your own server and keep your business data secure.
MailerQ is fast. Its sole purpose is to send emails. Storing, queuing and prioritizing messages is done in a separate AMQP message broker.
MailerQ gives you full control over queued messages. Monitor email delivery and intervene when necessary. Prioriziting and routing messages has never been easier.
Now available: MailerQ 4.0
A new version of MailerQ is available. MailerQ is Copernica's own MTA. Version 4.0 is even more powerful, flexible and stable, let alone the new features it comes with. We advise MailerQ users to (cautiously) switch to the new version in the near future.Learn more
MailerQ comes packed with features right out of the box to improve your email deliverability.
Automatically limit the amount of attempts, connections and number of messages over a single SMTP connection.
Messages that cannot be delivered are retried automatically. The interval between retries increases with every retry.
Store your private keys in the database or add them using the MailerQ management console.
Results are published back to RabbitMQ so your app can retrieve & process these results.
Specify from which IPs an email can be sent. If the first IP is unavailable, emails are then sent from the next available IP.
Send messages from one instance to another through SMTP when MailerQ instances are placed in sequence.
Allow multiple MailerQ instances communicate through a shared message queue in a clustered setup.
MailerQ recognizes domains that use the same mail servers and groups them automatically.
MailerQ uses RabbitMQ for queuing messages. Adding filters allows you to have full control over queued messages.
