How it works

Three guardrails, working in unison

Auth, tracking and hygiene are linked in DitLead — if any one slips, the others compensate.

STEP / 01

Auth check on every domain

SPF, DKIM and DMARC are validated continuously. Misconfigurations surface with a fix-it walkthrough.

STEP / 02

Custom tracking domain

Open and click tracking through your own subdomain — no shared-domain contamination, ever.

STEP / 03

Score watched live

0–100 per-mailbox score, refreshed every 6 hours. Drops trigger auto-throttle and a Slack alert.

Inside the suite

The deliverability stack, end-to-end

Most teams patch together GlockApps, a spam tester and an auth monitor. DitLead unifies the whole stack — and acts on what it finds.

01 · Auth

SPF, DKIM and DMARC, always green

DitLead validates auth records on every connected domain every hour. The dashboard surfaces broken records with copy-paste fixes for your DNS provider.

02 · Tracking

Your own tracking subdomain

Shared open/click tracking domains are one of the top hidden causes of spam placement. DitLead provisions a tracking subdomain on your domain (e.g. track.acme.io) with HTTPS and rotation built in.

HTTPS + CNAME setup with one click

Talk to sales

SPF/DKIM/DMARC continuous monitoring, custom tracking domains, blacklist checks across 12 major lists, spam-word filtering on every send, per-domain pacing, live reputation scoring, and Google Postmaster integration — all bundled and tuned together.

It combines auth health (SPF/DKIM/DMARC), warmup status, bounce rate, complaint rate, engagement and blacklist status into a single 0–100 score per mailbox. Below 70 triggers automatic throttling and an alert.

Yes, and DitLead handles the setup. Tracking opens and clicks through a subdomain of your own (e.g. track.acme.io) avoids reputation contamination from shared tracking domains — a major delivery factor most teams miss.

12 major lists including Spamhaus SBL/PBL/XBL, Barracuda, SORBS, SURBL, Proofpoint, URIBL and others. DitLead pings them daily and alerts on the first listing.

Yes. Every variant of every step is scored against 4,000+ trigger words and patterns before it ships. Risky language is surfaced with a suggested rewrite, and Gmail-promo-tab triggers are flagged separately.

The 55K inbox warmup network, 200+ placement-test seed accounts, SPF/DKIM/DMARC/BIMI audit, live per-mailbox reputation scoring, auto-throttle on reputation drift, spam-word scanning, per-domain send pacing, soft/hard-bounce classification and suppression. Everything works on every paid plan, no add-ons.

A 0–100 score per mailbox that aggregates: warmup-network engagement quality, placement-test results across seed inboxes, recent bounce-rate trend, complaint rate, blacklist presence, and authentication health. Updated every 30 seconds and visible per mailbox + per domain.

The placement-test seed accounts detect it in near-real-time (avg under 8 minutes from first send). Auto-throttle cuts campaign volume, increases warmup share on the affected mailbox, and surfaces a Slack/Teams alert with a one-click recovery playbook.

Yes. Use it with Gmail, Workspace, Outlook, M365, Yahoo, custom SMTP, or external relays (SendGrid, Mailgun, SES). Configuration is per mailbox so you can mix providers across your sending pool.

Yes. Once you've authenticated SPF/DKIM/DMARC at p=quarantine or stricter, DitLead can host the BIMI record and SVG logo. BIMI lifts open rates 5–10% on average where supported (Gmail, Yahoo, Apple Mail).

Stand-alone warmup tools handle one piece — warming new mailboxes. DitLead's suite covers the whole stack: warmup + placement testing + reputation scoring + auto-throttle + auth audit + spam filtering + per-domain pacing. Plus it's bundled with sending, so there's no second tool to manage.
