Email Deliverability Monitoring for Agencies

Monitor email deliverability across all client domains from one dashboard. Get alerts when authentication breaks—before client emails stop arriving.

Stop Explaining Why Client Emails Are Going to Spam

Your client calls. Their emails aren't getting responses. Sales leads are complaining. Newsletter open rates tanked overnight.

"We thought you were handling this?"

Maybe you set up their email authentication months ago. Maybe their IT person did. Either way, something broke and nobody noticed until the damage was done.

The Agency Email Problem

You manage websites, marketing, or technical services for clients. Email deliverability often falls into your scope—even when it shouldn't.

The challenges:

  • You set it up, but you don't monitor it: SPF, DKIM, DMARC get configured during onboarding. Then forgotten.
  • Things break without warning: DNS changes, expired DKIM keys, registrar migrations, accidental deletions.
  • You find out too late: The first sign of a problem is a client complaint about emails not arriving.
  • Multiple clients, multiple domains: Checking each one manually doesn't scale.

Email authentication isn't set-and-forget. Records change, things break, and clients assume someone is watching. Usually, nobody is.

What Email Deliverability Problems Cost Your Agency

Direct costs:

  • Hours diagnosing authentication issues
  • Emergency support calls
  • Rebuilding client trust after incidents
  • Unbillable crisis management time

Indirect costs:

  • Reputation damage: Client wonders what else you're not monitoring
  • Scope creep: "Shouldn't you have caught this?"
  • Lost renewals: Clients who lost deals due to email issues remember who was responsible

The worst case:

Client's domain lands on a major blacklist. Their emails bounce for days or weeks. They lose business, blame you, and you spend weeks on remediation—or lose the client entirely.

The Solution: Monitor What You Set Up

Email Deliverability Suite monitors all your client domains from one dashboard:

SPF monitoring

DKIM verification

Track DKIM key validity across all client domains.

DMARC checking

Monitor DMARC policies and alignment.

MX record monitoring

Catch mail server misconfigurations before they cause bounces.

Blacklist monitoring

Daily checks against major blacklists. Know if a client domain gets listed.

Unlimited domains

$39/month flat. Whether you have 10 clients or 200.

Monitor all client domains

One dashboard for unlimited domains. $39/month.

How Agencies Use Email Deliverability Suite

During client onboarding

1

Set up authentication

Configure SPF, DKIM, DMARC as part of your standard process.

2

Add to monitoring

Enter the domain, configure DKIM selectors. Takes 2 minutes.

3

Document the setup

Note what you configured and that monitoring is active.

This becomes part of your onboarding checklist. Every client, every time.

When you get an alert

Something broke. Maybe the client's IT team updated DNS. Maybe a DKIM key expired. The alert tells you what changed.

Response process:

  1. Diagnose using our free tools (SPF Record Check, DKIM Test, DMARC Record Checker)
  2. Fix the issue or escalate to whoever controls DNS
  3. Document the incident
  4. Alert resolves automatically when fixed

You catch problems in hours instead of days or weeks.

During client reviews

Pull up the monitoring dashboard. Show clients their email authentication status. Demonstrate the value you're providing.

"Here's your email deliverability status. Everything's green. We've been monitoring this since we onboarded you."

That's a differentiator.

Pricing for Agencies

$39/month for unlimited domains.

No per-domain fees. No tiers based on client count. Add domains as you add clients.

Billing clients for monitoring

Some agencies include this in their retainer. Others charge it as a line item:

| Approach | Example | |----------|---------| | Bundled | "Email deliverability monitoring included in maintenance" | | Line item | "$10/month per domain for authentication monitoring" | | Annual | "$75/year email security monitoring" |

At $39/month for unlimited domains, you can cover your entire client base and profit on every client.

If you charge just $5/month per client for deliverability monitoring and have 10 clients, you're breaking even. Every client beyond that is margin.

Common Agency Objections

"Our clients should monitor their own email."

They should. They don't. And when something breaks, they call you.

"We already have enough tools."

This one prevents problems instead of creating work. Five minutes to set up, then it runs itself.

"It's another subscription."

One prevented client emergency pays for years of monitoring. One saved client relationship pays for a decade.

"We can check manually."

You can. Will you? For every client, every week? The value of monitoring is that you don't have to remember.

What We Don't Do (And Why That's Good)

Email Deliverability Suite focuses on authentication and blacklist monitoring. We don't:

You have tools for those things. This tool watches what you set up and tells you when it breaks.
