Four sendrules capabilities mapped to the pain that defines this segment. Every one of them is on the free plan.

  • Inline list hygiene
  • Seed-list placement per ISP
  • Blocklist monitoring
  • One-click unsubscribe compliance
The pain

What you deal with today.

Newsletter subscribers churn — inboxes go dormant, addresses go dead, complaints arrive silently. A high bounce or complaint rate for a single ISP quietly tanks your inbox rate across every subscriber on that ISP. You need continuous list hygiene and continuous placement tracking, not a one-off audit.

How sendrules answers

What changes when you route through us.

sendrules cleans your list on every send (quality gate rejects the dead ones before your ESP sees them), tracks placement on a seed-list per ISP, monitors every major blocklist continuously, and gives you per-ISP compliance so a Yahoo issue shows up as a Yahoo number, not a mystery drop.

The four capabilities

Feature per pain, not the other way round.

Inline list hygiene

Quality gate runs on every send. Dead addresses, disposable domains, and typos are rejected before your ESP sees them — your bounce rate stays clean.

Seed-list placement per ISP

Seed inboxes across Gmail, Yahoo, Outlook, Apple, and more. Every campaign gets an inbox / Promotions / Spam score per ISP.

Read more →

Blocklist monitoring

Continuous checks against every major RBL. Alert the moment a sending IP appears — before subscribers notice.

One-click unsubscribe compliance

Inbound receive detects List-Unsubscribe mailto replies and writes to suppression automatically — Google/Yahoo bulk-sender rule met.

Where it lands

Concrete scenarios you can wire in this week.

  • Weekly newsletter with the quality gate cleaning the list on every send — no separate 'audit' step
  • Per-ISP placement report per campaign so a Yahoo drop shows up as a Yahoo number
  • Continuous blocklist monitoring on every sending IP with a webhook alert on listing
  • Sponsor / classified mail on a separate rule so a promotional burst can't affect the editorial send
  • Unsubscribe replies auto-processed into suppression — Google/Yahoo bulk-sender compliance
