Catch authentication and blocklist problems before clients ask

A domain gets listed

Campaigns keep sending. Nobody opens the blocklist until the client asks what happened.

Email authentication breaks

An SPF include can push the record over the 10-lookup limit, or a DKIM selector is removed during a tool migration.

The client asks for proof

You need a shareable report when a client asks what changed.

What the daily check covers

SPF

Exists, parses, and stays within 10 DNS lookups. Flags +all, which authorizes any sender.

DKIM

Common selectors plus any selector you add. An empty key means that selector was revoked.

DMARC

Checks the DMARC record, policy, and configured aggregate-report destinations.

MX

Checks whether the domain publishes mail exchange (MX) records.

Domain age

Registration date from RDAP when the registry publishes it.

Blocklists

Checks IP addresses found in the domain's A record, MX hosts, and explicit SPF entries.

Questions

What does InboxMonitor offer agencies?

Manage client domains in one dashboard. Agency adds Slack alerts and shareable client reports. Agency Pro adds reports with your own branding.

How often do you check?

Daily, on a schedule, plus whenever you hit Run check. The first check is the baseline. After that, a change for the worse sends an email. Slack alerts start on Agency.

Which blocklists do you check?

Today the check queries two IP blocklists, PSBL and 0spam. Domain-based lists and Spamhaus are not included yet.

Does InboxMonitor send email from my domains?

No. InboxMonitor only reads public DNS and blocklist data. It never sends mail from your domains.

Does InboxMonitor integrate with Instantly or Smartlead?

Not yet. Those integrations aren't available today. Bounce rates, reply rates, and inbox placement aren't monitored either.

What is on the free plan?

One domain, daily checks, and email alerts only. Upgrade when you need to monitor more domains. Shareable client reports and Slack start at Agency. White-label reports start at Agency Pro.
