Get StartedCommon questions about setup, compatibility, and sending limits.
No. You keep using your existing server or application as-is; you only need to configure our SMTP relay details in your outgoing mail settings.
Any application that supports the standard SMTP protocol — CRMs, e-commerce platforms, or your own custom software.
Each plan has its own sending volume limit; you can upgrade to a higher-capacity plan whenever your needs grow.
Depending on the plan, a shared or dedicated sending IP can be provided; dedicated IP requests are handled by our support team.
We maintain high delivery rates through continuous reputation monitoring, blacklist checks, and compliance with SPF/DKIM/DMARC standards; while no exact percentage is guaranteed, continuous monitoring allows fast intervention.
