Got questions? We’ve got answers.

A dedicated SMTP server ensures reliable and secure email delivery by giving you complete control over your sending infrastructure. Unlike shared servers, where multiple users share the same IP address (risking blacklisting and lower deliverability), a dedicated SMTP server assigns unique IP addresses exclusively to you. This improves sender reputation, enhances deliverability rates, and ensures your emails consistently reach the inbox. Maileroo Enterprise Edition can also help you comply with local data laws, set up and manage your own dedicated mail servers, and ensure your infrastructure is fully isolated from other tenants for maximum security. For large organizations, this setup can also be more cost-effective compared to shared services, especially with high-volume sending requirements.
While Maileroo Enterprise Edition's primary focus is on dedicated SMTP servers for high-volume email sending (transactional and marketing emails), we can also provide full email hosting services, including email inboxes and account management, on a special basis. If you require complete email hosting alongside our SMTP services, reach out to us with your specific needs. We’ll assess your requirements and provide a tailored solution to meet your business needs, ensuring seamless email management and delivery.
Yes, Maileroo Enterprise Edition's SMTP server supports sending both transactional and marketing emails, as well as personal emails. However, it is strictly against our policies to use the service for spam or unsolicited emails. Our platform is designed to ensure high deliverability and compliance, making it ideal for legitimate email sending needs, whether it’s for order confirmations, newsletters, or personal communications.
We handle the automatic warm-up of our dedicated IPs to build and maintain a strong reputation before you begin sending emails. We provide you with a dedicated IP pool and monitor your email traffic, adjusting the warm-up schedule as necessary. This process is crucial because ISPs are vigilant about protecting their users from unsolicited emails and potential spam. They analyze the behavior of new IPs to distinguish legitimate senders from spammers. Without proper warm-up, ISPs may flag your emails as suspicious, leading to delivery issues.
We ensure your email hosting is secure and compliant with rigorous standards. We offer tailored security features, including encryption both at rest and in transit, along with robust access controls. Our platform is fully compliant with regulations like GDPR and international standards such as ISO/IEC 27001:2013. Additionally, we have monitoring and alert systems in place to protect against unauthorized access and data breaches, giving you peace of mind about your email infrastructure.
Absolutely! Our platform is built to adapt to your unique needs. If you have specific requirements or ideas for custom features, we’re here to help. We take a collaborative approach to ensure that our solutions align perfectly with your goals, providing you with a tailored experience that meets your business objectives.
