Your emails are being sent. The question is whether they’re reaching the inbox.
Digistrat is a UK email deliverability consultant for teams whose email is already being sent and is not reliably reaching the inbox. Every one of those messages is revenue you have already earned and not received. The usual cause is not the subject line. It is authentication, sender reputation, list quality, or a sending programme that has drifted.
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.
I spent six years inside SendGrid, including as one of the first five people in EMEA, doing this work for companies on enterprise contracts. Digistrat is that same work, sold directly to growth-stage SaaS, e-commerce, and FinTech teams in the UK and Europe.
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.
Send one email from your platform and get a score across authentication, reputation signals, spam-filter results and compliance headers. A fail comes with a plain explanation of what it means.
Known cost, known timeline, one invoice. From £3,950, inclusive of 45 days of implementation. Report in 3 to 5 days.
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 across a 45-day window, and the report covers anything longer term. It is one invoice, from £3,950.
For ongoing performance, Ongoing Monitoring keeps watch.
We check your authentication, reputation and inbox placement on a continuous basis. Plain-English reports, direct access to your specialist, and annual terms.
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.
