Full Email Deliverability Audit
Find Out Why Your Emails Aren’t Reaching The Inbox
If opens, clicks or sales have slipped, a green SPF tick or a “delivered” status does not tell you enough. We investigate the technical setup, sender reputation, provider behaviour, list quality, sending patterns, content and tracking to find what is most likely holding your email back.

Why an audit matters
“Delivered” Does Not Mean “Seen”
An email can be accepted by Gmail, Microsoft or Yahoo and still land in spam, Promotions, Other or somewhere your customer barely notices. The audit joins provider-level placement evidence to the technical and reputation signals behind it, so you can see where the real problem sits.
Example of the type of provider-level comparison an audit can surface. Actual placement varies by sender, audience and mailbox provider.
What we investigate
A Full Review Of The Areas That Can Affect Inbox Placement
Where access or data is available, the audit covers the same core areas specialist deliverability services typically investigate, then pulls them together into one set of priorities.
Sending Domains & DNS
From domains, subdomains, return-path/envelope identity, MX where relevant, reverse DNS/PTR, HELO identity and the structure around your sending setup.
Inbox Placement
Provider-level testing across Gmail, Microsoft/Outlook, Yahoo and other relevant mailbox providers so you can see where test messages are actually landing.
Domain & IP Reputation
Signals attached to the sending domain and IPs, recent reputation patterns and whether shared or dedicated infrastructure may be working for or against you.
Google & Microsoft Signals
Google Postmaster Tools and Microsoft SNDS/JMRP evidence where available, treated as provider telemetry rather than a substitute for placement testing.
Blocklists & Spam Traps
Known blocklist exposure, likely causes, trap-risk indicators and whether a listing is a symptom of a wider reputation or acquisition problem.
List Health
Hard and soft bounces, complaints, stale contacts, invalid addresses, acquisition sources, suppressions and the risk in re-engaging old segments.
Engagement & Segmentation
How active and inactive contacts are being mailed, whether engagement is being used sensibly and whether low-quality segments are dragging down the rest of the programme.
Sending Volume & Warm-Up
Frequency, spikes, sudden volume changes, new-domain or new-IP ramping and whether the current sending pattern matches the reputation you have today.
ESP / MTA Infrastructure
Your sending platform, routes, pools, dedicated/shared IP choices, third-party senders and any infrastructure decisions that fragment or weaken reputation.
Content, HTML & Rendering
Template structure, text/image balance, heavy or broken HTML, mobile issues, accessibility basics and obvious message-level factors that can create problems.
Links & Tracking Domains
Link domains, redirects, tracking hostnames, URL reputation, shorteners, mismatched branding and whether the tracking setup creates unnecessary risk.
Headers & Unsubscribe
List-Unsubscribe and one-click unsubscribe support where appropriate, List-ID/identity consistency and other header-level signals used by modern mailbox providers.
Bounces & Complaints
How failures and complaints are handled, suppression behaviour, feedback-loop signals and whether bad addresses are being retried or recycled.
Consent & Acquisition Risk
A practical review of how contacts enter the list, whether the source is creating reputation problems and whether current sending expectations match what subscribers signed up for.
Prioritised Remediation Plan
You get the problems ranked by urgency and likely impact, with a clear distinction between quick fixes, structural work and issues that need monitoring over time.
What happens next
A Proper Investigation, Then A Clear Plan
We do not hand you a generic checklist. We collect the evidence, investigate what is actually driving the problem and turn it into a practical set of priorities.
We collect the evidence
Domains, ESP or server setup, recent campaigns, sending logs and provider dashboards where available.
We investigate the causes
We connect placement, authentication, reputation, list behaviour, content and infrastructure instead of looking at each in isolation.
You get a ranked action plan
You know what needs fixing first, what can wait, what needs monitoring and where bigger changes may be justified.

The difference
Why A Full Audit Goes Further Than A Free Checker
Free tools are useful for individual checks. They can tell you that a record exists, whether an IP appears on a blocklist or how one message scores. What they do not do well is connect those findings to each other.
Deliverability problems are often cumulative. A domain can pass authentication and still have poor reputation. A clean IP can still be attached to a weak domain. A technically perfect message can still be sent to the wrong segment at the wrong volume. The value of the audit is in joining those signals together.

Before You Order
What do you need from me?
Usually the sending domain, sending platform or server, recent campaign examples and access to relevant reputation dashboards or reports. We’ll tell you exactly what is needed after purchase.
Does an audit guarantee inbox placement?
No legitimate deliverability specialist can guarantee how every mailbox provider will place every future message. The audit is designed to identify the strongest evidence, the likely causes and the fixes that deserve priority.
Is remediation included?
The audit is the investigation and action plan. If you want Email Foundry to carry out wider recovery work afterwards, we can scope that separately based on what the audit finds.
Can you audit Klaviyo, Mailchimp, ActiveCampaign or a custom mail server?
Yes. The audit is centred on the sending system and provider behaviour rather than one particular ESP. The exact evidence available varies by platform.
Why not just use a free deliverability checker?
Free checkers are useful for individual tests. The audit is for connecting authentication, reputation, placement, list health, infrastructure and sending behaviour into one diagnosis and priority order.
