Why 94%?
The infrastructure decisions that keep your emails out of spam.
Dedicated IP warmup
Automated warm-up schedules so your sending reputation builds cleanly from day one.
Real-time blocklist check
Every send is screened against 50+ blocklists. Issues surface in your dashboard before they become a problem.
Separate stream pools
Transactional and marketing emails never share IP pools — a broadcast can't poison your password-reset reputation.
Per-domain analytics
See inbox placement, bounce rate, and complaint rate broken down by sending domain, not just account-wide averages.
