Email Marketing Mistakes That Cost Leicestershire Businesses Thousands

Before diving into specific mistakes, it's crucial to understand what's at stake. A typical Leicester SME with 2,000 email subscribers could miss out on £15,000-£30,000 in annual revenue through poor email practices. For larger businesses, these figures can reach six figures. So, let’s dive into the most common mistakes!

‍

The Hidden Cost of Poor Email Marketing

‍

Mistake #1: The Generic Blast Approach

The Problem: You are sending the same email to your entire database, e.g., from Leicester manufacturing prospects to Loughborough retail customers.

The Cost: Segmented campaigns can increase both open and click-through rates

The Fix: Segment by location (Leicester city vs. wider Leicestershire, for example), industry, purchase history, and engagement level.

‍

Mistake #2: Ignoring Mobile Optimisation

The Problem: In 2025, mobile devices account for 47.3% of all email opens, however, many organisations do not consider creating mobile-friendly emails

The Cost: Email unsubscribe rates are highest on mobile (0.17%), as users quickly dismiss non-mobile-friendly emails

The Fix: Use responsive design, keep subject lines under 30 characters, and ensure buttons are thumb-friendly (minimum 44px height).

‍

Mistake #3: Weak Subject Lines That Kill Open Rates

The Problem: Generic subject lines like "Monthly Newsletter" or "Special Offer" that fail to grab attention in crowded inboxes.

The Cost: 66% of email recipients decide whether to open an email based solely on the subject line. If your recipients do not open your email, you will miss out on additional opportunities to generate revenue.

The Fix: Consider unique, catchy subject lines, such as "Leicester's best-kept secret for [product]" or "Only 3 left in Leicestershire..." "Your Leicester neighbours are saving £200"

‍

Mistake #4: No Clear Call-to-Action (CTA)

The Problem: Emails that ramble without a clear next step, or worse, multiple competing CTAs that confuse recipients.

The Cost: According to Wordstream, emails with a single, clear CTA can increase clicks by up to 371% and sales by 1617%!

The Fix: One primary CTA per email, use action-oriented language, and make it visually prominent.

‍

Mistake #5: Poor Timing and Frequency

The Problem: Sending emails at random times or bombarding subscribers with daily messages.

The Cost: Email open rates are affected by send date and time

The Fix: Consider the following insights

• Email open rates are highest on Tuesdays.

• The average consumer checks their emails 15 times daily, most between 8am and 11am.

• 52% of users unsubscribe from emails due to high frequency, while 38% do so due to irrelevant content
