DELIVERY DISCIPLINE

Your customer’s inbox is where you belong.

A 99.97% delivery rate is no accident. Separate IP pool, gradual warm-up, continuous blocklist monitoring, pre-send spam score — provable discipline.

Three foundations

Delivery is the combination of three principles.

Reputation — Discipline — Visibility. Without all three, none of them means much on its own.

1. Reputation — Separate IP pool

Your neighbour’s spam doesn’t affect you; your disciplined sending pulls your delivery rate up. On the Enterprise plan, every customer gets its own isolated IP pool.

2. Discipline — Gradual warm-up

Sending from a new IP or a new domain doesn’t open to full volume on day one. A 14-day increasing schedule tells receiving systems "we’re here".

3. Visibility — Reputation panel

A live snapshot of your reputation. Sender Score, open rate, complaint rate, hard bounce rate — in one panel, in real time.

Warm-up schedule

A 14-day increasing volume curve.

Sending from a new IP or new domain doesn’t open to full volume on day one. This curve gradually builds your "trusted sender" reputation in the eyes of receiving systems.

Blocklist monitoring

19 RBL lists, checked every 5 minutes.

Reputation panel

Your reputation, at a single glance.

Three critical indicators: Sender Score, complaint rate, hard bounce rate. If these three are healthy, your delivery rate is healthy too.

Pre-send check

Find out before you land in spam.

Before every send, an industry-standard spam score is computed for content, headers and structure. If the threshold is exceeded you’re warned; no surprises in production.

Threshold-based check

≤ 5.0

Messages below this threshold can be sent. Above it you’re warned — fix and send, or keep it in drafts and improve.

No surprise spam folder in your production traffic, because every message is evaluated beforehand.
