Most advice about email campaigns is written for American audiences. A British subscriber notices when a “Memorial Day” template has been lightly edited, when prices appear without VAT, or when an offer lands at 3am because it was scheduled in New York time. The tips below are about getting those details right for a UK list.
1. Write like a British brand
Use British spelling (colour, organise, favourite), dates in day-month order, and prices in pounds. For consumer offers, show prices including VAT; business-to-business emails can show prices excluding VAT, as long as you say so. Tone matters too. Over-excited American-style copy with several exclamation marks often reads as spam to a UK audience. A clear, slightly understated voice usually performs better.
2. Earn the open with the subject line
Keep the subject specific and honest: “Boxing Day: 30% off winter coats until Sunday” beats “You won’t believe this!”. Say who you are in the sender name, add a preheader that completes the thought, and avoid misleading claims. The ASA’s CAP Code covers marketing emails, and fake urgency can breach consumer law. Our guide to writing effective subject lines has more examples, and Mailpro’s subject line generator can suggest variants.
3. Send when your readers are awake
The UK is on GMT in winter and BST (GMT+1) from the last Sunday in March to the last Sunday in October. Test weekday mornings, lunchtime and early evening for consumer lists; for B2B, mid-morning Tuesday to Thursday is a common starting point. Avoid bank holiday mornings for anything work-related. Our FAQ on the best time to send a newsletter explains how to test your own list, and you can schedule sends in advance.
4. Segment by nation when dates matter
St Andrew’s Day is a bank holiday in Scotland, St Patrick’s Day in Northern Ireland, and the August bank holiday falls on a different Monday in Scotland. A single UK-wide “bank holiday sale” email can land on a normal working day for part of your list. If you trade across the four nations, add a region field and target accordingly.
5. Design for the phone first
Many UK subscribers read email on a mobile, often on the commute. Use a single column, large buttons and short paragraphs, and check your images have alt text. Every Mailpro template is responsive, so it adapts to small screens without extra work.
6. Test before and after
- Before: send a test to Gmail, Outlook and an Apple Mail account, click every link and check the unsubscribe works.
- During: split-test one element at a time, such as subject line or send hour.
- After: compare results in your campaign statistics and note what to repeat.
7. Stay on the right side of PECR
Only email consumers who consented or who fall under the soft opt-in, identify yourself clearly and include a working opt-out in every message. Since February 2026 the ICO can fine PECR breaches up to £17.5 million or 4% of global turnover. If you are unsure whether a contact can be emailed, check our guide to UK email marketing law first.
