ImprovMX SMTP empowers you to send and reply directly from your domain address.

Enjoy this powerful feature alongside our Email Forwarding as part of our premium plans. Elevate your email experience with reliable transactional emails, customer communications, and more.

Send professional emails for your domain

Send and reply from your domain

Boost your brand image by sending and replying to emails directly from your custom domain addresses. Maintain a consistent professional presence across all communications.

Ideal for transactional emails

Automate email notifications, order confirmations, and more for your WordPress site or e-commerce store. Keep customers informed and streamline your operations.

Superior deliverability

To ensure your legitimate emails always get through, we leverage a vast pool of IP addresses. If an email encounters a deliverability issue due to a temporary IP reputation problem, our system intelligently retries sending from a different IP up to 5 times. This means those important confirmations and customer communications will reach their destination.

Multiple SMTP users

Grant different departments or team members their own SMTP settings for tailored email strategies and streamlined organisation.

A super simple interface to manage SMTP users

Effortlessly add, configure, and manage SMTP users with our intuitive, user-friendly interface.

Secure your account with convenient magic link login or traditional passwords, and add an extra layer of protection with Two-Factor Authentication (2FA).

Monitor email delivery performance with detailed logs, giving you valuable insights into your email communication.
