In one line
A sales letter persuades the reader to buy a product or service, and the AIDA plan structures it as Attention, Interest, Desire and Action.
Explained simply
Think of a good YouTube ad: the first second grabs you, then shows something interesting, then makes you want it, then says 'Buy now, 20 percent off till Sunday'. A sales letter follows the same journey on paper or e-mail.
Technically, a sales letter is a persuasive business letter addressed to prospective customers. It uses the you-attitude, focuses on benefits rather than only features, supports claims with evidence, and ends with a clear call to action.
How it works
- Attention: open with a hook: a question, a striking fact, an offer or a problem the reader faces. 'Tired of paying high electricity bills every month?'
- Interest: introduce the product and how it solves the problem; give key features in simple language.
- Desire: show benefits for the reader (savings, comfort, safety, status), support with evidence: specifications, testimonials, warranty, certifications, comparisons.
- Action: tell the reader exactly what to do and make it easy: call, visit, click, reply; add an incentive or deadline.
- Tone and style: positive, you-centred, honest; short paragraphs; no exaggerated or false claims.
- Format: complete block, with a catchy subject line.
Quick example
Sales letter outline for a solar water heater. Attention: 'Imagine hot water every morning without paying for electricity.' Interest: 'Our 200-litre SunHeat solar water heater is designed for a family of four and works even on cloudy days with its insulated tank.' Desire: 'Families using SunHeat have cut their water-heating bills sharply. It needs little maintenance and comes with a five-year warranty.' (State only figures and claims the company can prove.) Action: 'Call 1800-XXX-XXXX or visit our showroom before 31 December to get free installation.'
Common mistakes
- Listing technical features without translating them into benefits for the reader.
- Making exaggerated or unverifiable claims ('the best in the world'), which is unethical and unconvincing.
- Ending without a specific call to action.
How MU asks it
Asked as 'Draft a sales letter for ... using the AIDA approach' (6 to 8 marks) or 'Explain the AIDA technique' (3 to 5 marks). Use complete block format and label or clearly show each AIDA stage; examiners reward a strong opening, benefits with evidence and a clear action line.
