HOW WE GET
YOU TO THE
INBOX

Email deliverability isn't a single switch you flip. It's a collection of trust signals you send to ISPs over time. We audit, fix, and amplify every one of them.

01

Domain Health Audit

We start by diagnosing every technical factor that affects your sender reputation.

→ SPF record syntax and policy validation
→ DKIM key presence, selector discovery, and 2048-bit enforcement
→ DMARC policy check — p=none, quarantine, or reject
→ Blacklist scan across 80+ RBLs including Spamhaus, Barracuda, SURBL
→ MX record validation and reverse DNS check
→ Sending domain age and history lookup
Most senders have at least one critical misconfiguration they don't know about. We find them all in one pass.
02

Authentication Hardening

We fix every authentication gap so ISPs can verify your identity before your email even reaches a filter.

→ SPF record cleanup — remove +all, flatten includes, correct syntax
→ DKIM key upgrade to 2048-bit with proper selector configuration
→ DMARC enforcement path: none → quarantine → reject with RUA/RUF reporting
→ BIMI record setup (Growth and Pro plans)
→ Return-path alignment for DMARC compliance
→ Step-by-step DNS change instructions or we handle it directly
Authentication isn't about deliverability theory — it's the actual technical spec Gmail, Outlook, and Yahoo use to decide if your emails are legitimate.
03

Seed List Warm-Up

Our network of engaged inboxes sends positive engagement signals to every major ISP on your behalf.

→ Real inboxes at Gmail, Outlook, Yahoo, Apple Mail, and AOL
→ Seed addresses open, click, and reply to your campaigns
→ Signals teach ISPs that your emails are wanted and valuable
→ Removes your domain from low-engagement penalty buckets
→ Compounds over time — the longer you run it, the stronger your reputation
→ Full reporting on seed inbox placement before you send to your list
This is the signal amplification layer that separates InboxSmarts from a basic deliverability audit tool.
04

Inbox Placement Testing

Before you hit send to your real list, we tell you exactly where your emails will land.

→ Test rendering and placement across Gmail (primary, promotions, spam)
→ Outlook inbox vs. junk folder
→ Yahoo and AOL inbox vs. spam
→ Apple Mail inbox testing
→ Subject line and content scoring
→ Full placement report with actionable recommendations
Stop guessing. Know before you send.
05

Ongoing Monitoring & Reporting

Deliverability is a living score, not a one-time fix. We track it continuously.

→ Real-time blacklist monitoring with instant alerts
→ Google Postmaster Tools integration and interpretation
→ DMARC aggregate report analysis — who's sending on your behalf
→ Monthly deliverability health report
→ Sender score and domain reputation trending
→ Proactive outreach if we detect a problem before you do
Most reputation problems start small. We catch them early — before they become inbox crises.

WHAT ISPS
ACTUALLY MEASURE

Authentication
SPF, DKIM, DMARC — the baseline trust layer every major ISP checks first.
Engagement Rate
Opens, clicks, and replies tell ISPs your emails are wanted. We pump this signal.
Complaint Rate
Spam reports tank your reputation fast. We monitor and help you stay under 0.1%.
Sending Volume
Sudden spikes trigger spam filters. Consistent, growing volume builds trust.
Domain Age & History
Older domains with clean histories get more trust. We protect yours.
List Hygiene
Hard bounces and stale addresses hurt your score. We flag them early.
Content Signals
Spam trigger words and certain HTML patterns affect placement. We test for them.
Blacklist Status
Even one listing can collapse your deliverability. We monitor and remove you.
