Marketing “Best Practice” now for the window industry
Marketing Best Practice for the Window Industry
In an era dominated by digital noise, mailshots remain a powerful force in direct marketing. At Insight Data, we’ve seen a significant uptick in targeted campaigns across the construction and fenestration industries, proving that tangible, targeted mail still delivers results.
We’ve seen a consistent rise in clients using our prospect data to launch personalised mail campaigns, generating measurable response rates and solid returns. While email marketing remains dominant, especially since our email marketing deliverability rate of 98% sets the benchmark, direct mail is increasingly being used to reinforce brand presence and drive engagement.
Why Are Mailshots Still Effective?
Mailshots cut through the clutter. A physical brochure, postcard, or letter gets noticed, handled, and read. When supported with accurate, targeted data, they go straight to the decision-maker, something few digital platforms can guarantee.
Our clients use mailshots to generate leads, drive event attendance, introduce new products, and support larger marketing campaigns. Many combine it with digital channels running parallel email and social campaigns for maximum impact.
Accuracy and Results with Verified Data
Mailshots are only as good as the data behind them. That’s why Insight Data maintains and updates its prospect databases daily. Whether you’re targeting window and door fabricators, architects, local builders, or housebuilders, you’ll be working with accurate, GDPR-compliant contact records.
As our Fenestration Database breaks through 17,000 verified email addresses, many users are now complementing email campaigns with physical mailshots, particularly when launching a new product or brand.
Full Campaign Management
With our in-house campaign team, clients benefit from full-service support. From creative design to print and fulfilment, we manage your mailshot from start to finish, ensuring every item lands where it needs to when it needs to.

Campaigns are tracked using Salestracker, our online marketing system, which logs activity against each prospect and lets you monitor ROI and follow up leads efficiently.
Reaching the Right People
Because we maintain direct contact with businesses across the supply chain, we guarantee your mail reaches the right person, buyers, directors, specifiers, not generic job titles or outdated addresses. That’s the difference between wasted budget and effective marketing.
Print Is Far from Dead
Far from being replaced by digital, mailshots are enjoying a resurgence, especially when integrated with email, social, and telesales. With so many brands relying on digital-only marketing, physical mail stands out.
Our research team updates every record in our database on a rolling basis, so your campaign gets real, usable results, not bounces and gone-aways.
“In a digital-first world, physical marketing materials give our clients a serious edge. When used properly, mailshots build credibility and reinforce your brand in a way that’s hard to ignore. We’re helping businesses generate more business across every channel.” — Alex Tremlett, Commercial Director, Insight Data
