Can I use a Dedicated IP?

Yes, we do provide dedicated IPs, but you’ll need to contact an admin to have them enabled.

What types of emails does your service support?

We support both transactional emails (such as verification codes, password resets, and order notifications) and marketing emails (such as promotional campaigns, newsletters, and automated marketing flows). Whether you need real-time delivery or large-scale marketing sends, we've got you covered.

Can I use your drag-and-drop editor to create marketing emails?

Yes! Our platform includes a visual drag-and-drop editor that allows you to create professional marketing emails without writing any code. It also supports reusable blocks, template management, and real-time previews across different devices.
