UK email deliverability specialist

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.

The problem

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.

Transactional emails landing in spam for some recipients but not others

Why it happens

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.

How it starts

It starts with a free inbox check-up.

We run a full technical check on your domain.

When you book, your confirmation email will include our check address. Send a test email from your platform before the call if you would like us to include a live send test. Either way, we run SPF, DKIM, DMARC, blocklist status, and sender reputation checks before we speak.

We run your domain through a full technical check.

SPF, DKIM, DMARC, BIMI, blocklist status, and sender reputation. Results ready before the call.

You get a clear picture of where your emails stand.

In 15 minutes you will know what is working, what is not, what it means for your programme, and what it is likely costing you. No pitch, no expectation that anything comes next.

What makes Digistrat different

We look at the part nobody else has been checking.

Most deliverability consultants audit the technical layer, checking authentication records, blacklist 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 audits cover

  • Authentication records (SPF, DKIM, DMARC)
  • Blacklist status
  • IP reputation
  • Basic configuration checks

+ What a Digistrat audit 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.
