We set up email deliverability for UK businesses — SPF, DKIM and DMARC configured correctly, plus the domain warm-up that goes with them, so the email you send actually reaches the inbox instead of spam or nowhere at all. Deliverability is really just proof: three DNS records that tell Gmail, Outlook and everyone else that a message genuinely came from you and hasn't been tampered with on the way.
Most deliverability problems aren't a broken email service, they're a missing or half-finished DNS record — an SPF record that doesn't cover every tool sending on your behalf, a DKIM key that was never switched on, or a DMARC policy left on 'do nothing' because nobody wanted to risk emails bouncing. Add a brand-new domain sending a few hundred emails on day one with no sending history behind it, and providers treat you as a stranger — however careful the setup, the volume alone trips the spam filter.
New sending domain → SPF, DKIM and DMARC records written, verified and checked against every service that sends on your behalf
Existing domain with patchy deliverability → records audited line by line to find the actual cause of the spam-folder problem before anything changes
DMARC policy moved from 'none' to 'quarantine' to 'reject' in stages, with reports checked at each step so nothing genuine gets blocked
New domain or IP → warmed up on a gradual sending schedule so mailbox providers build up trust before you rely on it for real volume
Transactional email — receipts, password resets, booking confirmations — monitored separately from marketing sends, so one bad campaign can't take the important ones down with it
Monthly deliverability check → inbox placement and DMARC reports reviewed so a problem gets caught before customers start asking why your emails end up in spam
SPF is a DNS record listing which servers are allowed to send email as your domain. DKIM adds a digital signature proving the message wasn't altered in transit. DMARC tells receiving providers what to do if a message fails either check, and sends you a report when it happens. Get all three right and providers trust that mail claiming to be from you actually is.
Nine times out of ten it's one of a handful of things: a missing or incomplete SPF record, DKIM that was never switched on for every sending tool, a brand-new domain with no sending history, or a DMARC policy that isn't enforcing anything. We check all of them, in that order, before touching anything else.
Sending a small, steadily increasing volume from a new domain or IP so mailbox providers build up a track record for it, rather than seeing a stranger suddenly send thousands of emails on day one. It usually takes two to four weeks depending on your volume, and we set the schedule so real customer email keeps working throughout.
Auditing and correcting SPF, DKIM and DMARC for a single domain starts at £350, fixed price. If you're also warming up a new domain or sending from several subdomains and platforms, we'll quote that as one fixed number after a short look at your setup.
It can, if it's done carelessly — jumping straight to 'reject' before you know every legitimate sender is passing SPF and DKIM will bounce genuine email along with the fake stuff. We move the policy up in stages and watch the reports at each one, so nothing gets blocked that shouldn't be.
The DNS records are a one-off fix, but deliverability drifts — a new marketing tool gets added and nobody updates the SPF record, or a spike in complaints hurts your sender reputation. A short monthly check catches that before it costs you inbox placement.
