Key takeaways
- Use a short, punchy subject line and put the most important words at the start, since many readers see only the first 3–5 words, especially on smartphones or tablets.
- Keep detailed information in the email body, don’t try to convey your full marketing message in the subject line.
- Write as if speaking to a friend: conversational, personal and not like a call-centre script.
- Tasteful humour can increase opens. There’s an 8% open-rate rise in the UK when subject lines used words like ‘blips’ and ‘most embarrassing’.
- Be consistent in delivery frequency and content type so subscribers learn when and why to open your emails.

FAQ
Keep subject lines succinct and place the most important part at the beginning. Many readers scan only the first three to five words, especially on smartphones or tablets, so reserve details for the email body.
Craft emails conversationally, as if speaking to a friend. Write as though it’s just you and the recipient, avoid call-centre phrasing and aim to make each reader feel like the only person who received the message.
Yes. Tasteful humour can make emails memorable and increase opens. For example, including words like ‘blips’ and ‘most embarrassing’ in UK subject lines correlated with an 8% increase in open rates, humour should be tasteful and can reference trending elements.
Plan your delivery frequency and then be consistent in both timing and content. If subscribers expect monthly contact, send monthly and if they expect special offers and news, deliver those. Consistency helps condition the audience to open your emails.
Aside from being filtered to the spam folder, emails get ignored for reasons such as lengthy or bloated subject lines, impersonal or robotic tone and inconsistent delivery that fails to meet subscriber expectations.
