Email deliverability for Manchester ecommerce teams

What to take away

What Manchester ecommerce senders need from an email agency

Manchester is not a generic agency market. Boohoo Group and THG are both headquartered in the city, JD Sports sits a few miles away in Bury, and that cluster has built a deep pool of in-house email staff. People who leave those teams often set up on their own.

So buyers here are rarely new to the discipline. They know a spam folder when they see one, and they know open rates stopped being a reliable signal once Apple began proxying image loads. What they want is a second pair of hands with seed panels, blocklist tooling and time to read the data.

Most local ecommerce senders run Shopify, Klaviyo or Dotdigital, and their mail sits on one or two subdomains. Segmentation is usually strong. Authentication on the marketing subdomain is the weak point, because transactional mail was configured first and nobody revisited the DNS records.

List quality comes up in most first conversations. A short permission audit is often the first paid task, and it is the one that most often shifts the result. Our piece on permission audits to migration covers where that work sits.

Named Manchester email agencies and the work they publish

Five agencies come up repeatedly among Manchester ecommerce senders. Service lines move, so check each site and each filing before you take a meeting.

Thoughtful Digital publishes lifecycle and automation work, mainly Klaviyo and Shopify. Its case studies lean on segmentation and flow rebuilds rather than placement data. Ask which seed panel it uses, and what provider mix that panel covers.

The Ecommerce Agency publishes retention and CRM work for established retailers, with post-purchase journeys in front. Its clients tend to send at high volume. Ask how it separates sender reputation problems from list quality problems before it sells you a fix.

Fluid Digital is Shopify-focused and publishes retention, email and conversion work, including audits. Ask whether those audits cover SPF, DKIM and DMARC or content review alone, because both are sold under the same word.

Digital Ethos runs paid media alongside email and publishes performance reporting. The advantage for an ecommerce client is tying placement to revenue. Ask for the seed results behind any placement figure in its case studies.

KOMI Group is social-first and treats email as a support channel, which suits brands whose list plays second fiddle to social acquisition. It is the weakest of the five for a pure deliverability brief. Ask what it runs in-house.

Check the entity before anyone gets access to your domains. Search the trading name at Companies House, then compare three fields: registered name on the invoice, company number and registered office. If Fluid Digital invoices you from a differently named company, ask why before paying.

Accounts long overdue while the firm pitches a large retainer are a warning. A trading name that does not match the invoice is a worse one.

Manchester also has freelancers and two-person studios that test well. Size is not the signal. Whether the agency will name the tests, the tools and the person responsible is. Our notes on verified identity and a testable brief set out that standard.

Deliverability tests to discuss with a Manchester agency

None of the five publishes a full test specification. The checks below are practical areas to discuss with an ecommerce agency, not a description of a method used by any named firm.

Depth varies. Lifecycle-led shops tend to test after a change. Agencies with high-volume retail clients should test weekly, because order and shipping mail is time-sensitive, and a campaign that lands in promotions on a Friday costs a weekend of revenue.

Tie each test to a decision. If placement falls below an agreed threshold, pause and investigate the cause. That is the difference between a report and a control.

Access is part of the ask. Your sending platform and DNS need temporary roles, revoked at the end, with a record of who held them. Weigh that against the service standards a buyer can own.

Inbox placement, seed testing and authentication checks in practice

Seed testing email works by mailing a campaign to mailboxes the provider controls. Each mailbox reports the folder that received it, so the result is a placement rate by provider rather than one score.

Examples of seed-based inbox placement tools to evaluate include GlockApps Inbox Insight and Validity Everest. Check that the option you choose covers the mailbox providers and reporting you need; seed results are a guide, not a guarantee of placement for every recipient.

Inbox placement testing is the larger version of the same idea. Panels of hundreds or thousands of mailboxes give a steadier picture at higher cost. A Manchester retailer sending a few campaigns a week can run a mid-size panel monthly, and a small one after every DNS change.

Authentication is the part you control most directly. DMARC with alignment is an important control for bulk senders; Gmail's sender guidelines allow a DMARC policy of p=none. Without DMARC, Gmail and Microsoft may filter or reject mail whatever the content says.

Worked example for a Manchester apparel retailer:

Those figures are illustrative, not a benchmark. Ask for before and after on the same panel, the same providers and the same week of the month.

Compare suppliers the way you would compare software, using witnessed tests and exclusion criteria. Agree what counts as failure before the test begins.

ICO and ASA rules that constrain agency testing claims

Deliverability work sits inside UK marketing law, and two regulators decide what an agency may do and what it may claim.

The ICO enforces PECR and the UK GDPR. Its Direct marketing guidance covers consent, the soft opt-in and the right to object.

For testing, two points follow. Seed panels must be the agency's own mailboxes, never addresses borrowed from your list, and consent records must cover every address you mail, including those inherited in a platform migration.

An agency that seeds a bought list to prove a point has created a complaint problem, whatever the placement graph shows. Complaint rates above the thresholds Google publishes for bulk senders damage placement for months, and no clean-up campaign repairs a permission problem.

The ASA applies its advertising codes to claims in marketing, including claims on agency websites and in the emails they write for you. The CAP Code's Section 3.7 requires documentary evidence for objective claims. A fixed placement rate is difficult to substantiate across providers, and a promise of the inbox sits outside the sender's control. Read the ASA's advertising codes before approving claims.

For an objective placement claim, retain the dated panel results and method as documentary evidence under CAP Code Section 3.7.

Agencies can test claims before publishing them. The Copy Advice service gives confidential guidance, free to members, on subject lines and offers.

The practical rule for a buyer is this: any placement figure in a proposal needs a method attached, covering panel size, provider mix, test date and baseline.

How to brief a Manchester agency with a testable deliverability scope

A brief an agency can be held to is short. Use this checklist before you send it.

Then run it as a sequence:

Scope creep is the main cost risk. Deliverability work drifts into content, design and list growth, each with its own budget line. Treat a wider programme as new work with a new brief.

Plan the handover at the start. Ask for results your team can rerun, and for DNS changes logged in your own ticket system. If a change of supplier is likely, read our notes on due diligence on an email supplier.
