Free audit

The 25-point deliverability audit

A free, 25-point review of where your sending stands — authentication, reputation, MTA configuration, inbox placement and bulk-sender compliance. You receive a written assessment with prioritized findings. No charge, and no obligation to work with us afterward.

What we check

Twenty-five points, five layers.

The same checklist we run before any engagement. It works at infrastructure level, not just the surface a dashboard shows you.

01

Authentication & DNS

  • SPF record validity and lookup count
  • DKIM signing, key strength and rotation
  • DMARC policy and enforcement level
  • MTA-STS and TLS-RPT presence
  • Reverse DNS (PTR) and HELO alignment
02

Reputation

  • Sending IP reputation and history
  • Domain and subdomain reputation
  • Blacklist status across Spamhaus and major RBLs
  • Google Postmaster and Microsoft SNDS signals
  • Dedicated vs shared IP fit for your volume
03

Infrastructure & MTA

  • MTA configuration and version
  • VirtualMTA / egress source segmentation
  • Queue, retry and throttling policy
  • Bounce and feedback-loop processing
  • Outbound TLS and connection reuse
04

Deliverability & engagement

  • Seed-list inbox placement by provider
  • Spam-folder and missing-mail rate
  • Engagement signals: opens, replies, deletes
  • List hygiene and hard-bounce rate
  • Complaint rate against provider thresholds
05

Compliance & list

  • One-click unsubscribe (RFC 8058)
  • Bulk-sender requirements: Gmail, Yahoo, Microsoft
  • Consent and opt-in records
  • Transactional / marketing stream separation
  • Regional rules: GDPR, LGPD, CASL
