Your emails are being sent. The question is whether they’re reaching the inbox.
Every email that lands in spam instead of the inbox is revenue your business has already earned but never received. Most email problems are not caused by the wrong subject line. They are caused by how your sending infrastructure, sender reputation, and list quality have drifted over time, alongside your overall sending strategy. Digistrat finds out what’s wrong and fixes it properly.



Most email problems are invisible until they become expensive.
They do not announce themselves with an error message or a warning from your platform. Instead, open rates start dropping quietly over several weeks, users begin failing to complete sign-up because a verification email never arrived, and customers start calling to say their invoice went somewhere other than their inbox. By the time any of that is visible in the numbers, the problem has usually been building for months.
Open rates that have dropped without explanation
New users not completing sign-up because a welcome email never arrived
Transactional emails landing in spam for some recipients but not others
A recent platform or ESP migration that quietly broke something nobody has noticed yet
An email programme you have recently inherited, with no record of the decisions made before you arrived or what they might be costing you
Customers reporting they are not receiving emails you can see were sent
The businesses that need deliverability expertise most are often the ones who cannot access it. Digistrat exists to close that gap.
The teams with the deepest deliverability knowledge are the professional services departments inside major email platforms, and while they are excellent at what they do, they are priced for enterprise contracts and structured around clients spending several times your budget on platform fees.
The result is that businesses with real problems and sensible budgets have been left without a serious specialist option, regardless of their sector or size.
Every engagement starts the same way: find out exactly what is wrong and get it fixed.
Every engagement starts with a free health check. From there, the path depends on what we find.

A full investigation into your sending setup. Report and plan within days, quick fixes implemented within the first 30 days, and a plain-English report covering anything longer term.
Continuous monitoring of your sending health with direct access to your specialist and monthly reporting.
We also offer standalone specialist services: ESP migration, IP warm-up, authentication setup, and reputation recovery.
Start with the free health check. It takes less than a minute.
Run the free health check.
Send one email from your platform to our check address. The tool scores your authentication, infrastructure and key compliance signals instantly and shows you what it found.
If issues are found, we investigate and fix them.
The Deliverability Review and Fix is a full investigation into your sending setup. You receive a full report and plan within three to five days, the quick fixes are implemented within the first 30 days, and the report covers anything longer term.
For ongoing performance, the monitoring retainer keeps watch.
We check your authentication, reputation and inbox placement on a continuous basis. Monthly reports, direct access to your specialist, and no minimum term.
We look at the part nobody else has been checking.
Most deliverability consultants investigate the technical layer, checking authentication records, blocklist status, and IP reputation, which is the necessary starting point but not the complete picture. The problems that cause the most commercial damage are often in the layer underneath.
· What most investigations cover
- Authentication records (SPF, DKIM, DMARC)
- Blocklist status
- IP reputation
- Basic configuration checks
+ What a Digistrat full investigation covers, in addition
- How a sending programme has grown over time
- How lifecycle triggers stack up across real user journeys, sometimes producing far more email than anyone intended
- Whether segmentation still reflects who is actually engaging rather than who was engaging eighteen months ago
- Whether a recent volume shift has created reputation risk that has not yet shown up in the numbers
- Sending behaviour, cadence, and volume patterns over time
We look at all of it, technical and behavioural, infrastructure and strategy, because the answer to why emails are not landing is almost always in the part that was not on the standard checklist. This is what the Deliverability Review and Fix covers, and it goes significantly beyond what the free health check alone can show.
