Email Deliverability in Leicester

Getting a Leicester business's email into inboxes rather than spam folders. Gmail and Microsoft tightened their requirements substantially, and senders who never configured authentication properly found mail that used to arrive suddenly being rejected or filtered without any warning at all, usually at the worst possible moment.

Why this comes up

The problem

Deliverability fails silently. Nothing bounces visibly, nobody reports an error, and the business simply notices fewer replies — often months after the underlying problem started.

What you get

What we deliver

  • SPF, DKIM and DMARC configured correctly and verified against real sends
  • DMARC introduced in monitoring mode first, so legitimate mail is not blocked during rollout
  • Sending domain separated from your main domain where volume justifies it
  • Blacklist checks and delisting where your IP or domain has been listed
  • List hygiene — removing hard bounces, spam traps and long-term non-openers
  • Content and formatting reviewed for the patterns that trigger filtering

Thirty minutes, no charge, no sales script. You leave with a written summary of what email deliverability would actually involve — whether or not you use us.

Leicester is our home city. We are based here, most of our team lives here, and a good share of our clients are within a half-hour drive — which means site visits, workshops and hardware installs happen in person rather than over a call.

The most common briefs here are ecommerce for the city's textile and food manufacturers, booking systems for its large independent hospitality scene, and stock and logistics integration for distributors along the M1 corridor.

Email Deliverability in Leicester — common questions

Why did our email start going to spam without anything changing?
Usually because the receiving side changed. Gmail and Microsoft raised their authentication requirements for bulk senders, and mail that previously slipped through unauthenticated now gets filtered. Nothing on your side broke — the tolerance disappeared.
What is DMARC and do we need it?
It tells receiving servers what to do with mail claiming to be from you that fails authentication. Bulk senders effectively need it now. It must be introduced gradually — starting at reject can block your own legitimate mail from systems you forgot send on your behalf.
Should marketing email come from a different domain?
At volume, yes — usually a subdomain. It isolates your main domain's reputation, so a poorly performing campaign does not affect whether your invoices and quotes reach people.
We bought a list. Can you fix the deliverability?
Partly, and the honest advice is to stop sending to it. Purchased lists contain spam traps that damage sender reputation quickly, and under UK GDPR and PECR marketing to them is generally unlawful anyway.
Do you work with businesses across Leicestershire?
Yes. We are based in Leicester, United Kingdom and work with clients throughout East Midlands, including Leicester and the surrounding Leicestershire area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Leicester businesses do you usually work with?
The most common briefs here are ecommerce for the city's textile and food manufacturers, booking systems for its large independent hospitality scene, and stock and logistics integration for distributors along the M1 corridor. Beyond that we work across Manufacturing, Textiles & Fashion, Logistics, Food & Drink, Retail and Higher Education.
Do you cover the areas around Leicester?
Yes — we work throughout East Midlands, including Loughborough, Nottingham, Derby, Coventry, Northampton. Leicester is an urban area of roughly 560,000+, and we take on work across the wider Leicestershire region rather than the city boundary alone.
