Enterprise-grade infrastructure. Inbox placement built in.

IP Warmup Automation

New sending infrastructure needs to earn ISP trust before reaching full volume. SuperMailr's built-in IP warmup automation manages this for you. Choose a linear or exponential ramp strategy, set your target volume, and the platform enforces daily sending limits automatically — increasing them on schedule as your sender reputation builds.

Most platforms require you to purchase a separate warmup service or manage it manually. With SuperMailr, warmup is built in.

Bounce Handling

Hard bounces — permanent delivery failures — are automatically removed from your active lists after they occur. Soft bounces (temporary failures) are tracked separately and managed based on configurable retry logic. Keeping bounce rates low is essential to maintaining a healthy sender reputation, and SuperMailr handles it automatically.

Real-Time Deliverability Monitoring

See your inbox placement rates, spam complaint rates, and sender reputation signals in real time from the dashboard. Receive alerts when metrics move into concerning territory so you can act before a problem becomes a crisis.

Custom Tracking Domains

By default, email tracking links use a shared domain. Custom tracking domains let you replace this with your own domain — so tracking links look like they come from you, not from a shared infrastructure that may have a mixed reputation. This improves both deliverability and brand consistency in your emails.

Domain Authentication Support

SuperMailr provides guided setup for SPF, DKIM, and DMARC — the three authentication protocols that tell ISPs you're a legitimate sender. Step-by-step instructions walk you through adding the required DNS records for your domain. Authentication is a requirement for inbox placement in 2026 — not optional.
