As of 13 August 2026, AI can only partly improve email deliverability for your UK business.

What to actually do

1. Hand it to a person

   The route this page recommends

   Someone with a licence or accountable authority has to sign this before it counts.

2. Use a tool built for this

   Second choice

3. Do it yourself

   The distant third

   A chat interface, power-user skill, and roughly 1 hour until you can act on the result.

   How to actually do it

   1. Open your email platform or CRM and export recent campaign results showing delivered messages, bounces, complaints, opens and clicks, then remove recipient names and email addresses.
   2. Open the sending domain's DNS control panel and an email authentication test, and gather the current SPF, DKIM and DMARC records plus any authentication failure results.
   3. Collect recent blocklist, reputation and mailbox placement results, along with a note of any recent change to sending volume, templates, links, domains or recipient lists.
   4. Paste the anonymised evidence and business details into the prompt, then ask the chatbot to label each diagnosis as confirmed, plausible or unknown.
   5. Check every proposed DNS or platform change against your email provider's current documentation and have a technically competent colleague or deliverability specialist approve changes that affect authentication or sending behaviour.
   6. Send a controlled test to mailboxes you own across the relevant providers, compare authentication and placement results before and after each change, and record the result in the monitoring checklist.
   7. Check your consent and suppression processes against current ICO and GOV.UK guidance before changing who receives marketing email, and obtain professional advice for any uncertain or serious compliance issue.

   Prompt

   Act as an email deliverability analyst for a UK business. Analyse the information below and produce a prioritised plan to improve inbox placement without inventing facts.
   
   Business and sending setup:
   - Business type: [describe the business]
   - Sending domain: [domain]
   - Email platform or CRM: [name]
   - Main sending purpose: [marketing, transactional, prospecting or other]
   - Audience and consent source: [describe how recipients opted in or were contacted]
   - Typical sending volume and frequency: [details]
   
   Evidence:
   - Recent delivery, bounce, complaint and open data: [paste report]
   - Authentication results for SPF, DKIM and DMARC: [paste results]
   - DNS records relevant to email: [paste records or test results]
   - Reputation or blocklist alerts: [paste results]
   - Recent changes to domain, content, lists or sending volume: [details]
   
   Return:
   1. The three most likely causes of the problem, marking each as confirmed, plausible or unknown.
   2. A step by step action plan, ordered by impact and reversibility.
   3. Exact settings, record types or report fields I should inspect, but do not invent values that are missing.
   4. Tests to run before and after each change, including what result would confirm or reject the diagnosis.
   5. A monitoring checklist for the next campaigns.
   6. Separate technical deliverability issues from UK consent and privacy issues. Do not decide whether my activity complies with PECR or UK GDPR, and do not present legal conclusions as facts. Tell me which points need checking with current ICO or GOV.UK guidance and which need a specialist.
   
   State clearly what you cannot diagnose from the supplied evidence. Do not recommend buying lists, disguising unsolicited mail or bypassing mailbox provider controls.
