Why do introduction letters still work for trades?
Introduction letters still work for trades because they are relevant, timely, and non-intrusive. When a letter is linked to a real, planned project, it feels informative rather than promotional and allows a property owner to respond in their own time.
For tradespeople working on planned or permission-based work, this approach often leads to better-quality conversations than cold calls or adverts.
Why letters feel different to ads and calls
Cold calls and online ads interrupt people.
Letters don’t.
A letter:
-
Can be read when it suits the property owner
-
Provides context without pressure
-
Doesn’t demand an immediate response
When done properly, it feels more like an introduction than a sales pitch.
Relevance matters more than volume
Introduction letters work best when they are relevant.
For example:
-
A glazing company writing after a planning application involving windows or doors
-
A renewable energy company introducing themselves after plans for solar panels or heat pumps
-
An arborist making contact following an application involving tree works or access
The relevance of the timing and project is what makes the letter effective — not the volume sent.
Why timing is so important
Planning applications often appear weeks or months before work begins.
At this stage, property owners are:
-
Still forming plans
-
Researching options
-
Deciding who to speak to
An introduction letter at this point puts a trade on the radar early, before decisions are locked in and before price comparisons dominate.
Why letters still get read
Despite the growth of digital marketing, letters still stand out because:
-
Most marketing is now online
-
Physical mail feels deliberate and considered
-
There is far less competition in the letterbox
When the message is short, clear, and relevant, letters are more likely to be read than ignored.
What makes an introduction letter effective
Tradespeople see better results when letters are:
-
Short and easy to read
-
Clearly linked to a real project
-
Helpful rather than sales-focused
-
Written in plain, professional language
The goal is not to “sell”, but to let the property owner know who you are and what you specialise in.
When letters are less effective
Introduction letters are less effective when:
-
They are generic or mass-produced
-
They are sent too late in the process
-
The work doesn’t match the trade’s specialism
-
The trade relies on urgent or emergency work
Like planning-led outreach in general, letters suit trades focused on planned projects rather than instant demand.
How letters fit into a wider approach
Many tradespeople use letters alongside:
-
Word-of-mouth referrals
-
Local reputation and reviews
-
Existing customer work
Letters are not about replacing everything else — they are about creating early visibility and future opportunities.
