Spectrum® Window Films is a premium window film brand for automotive and architectural applications, with a product line spanning the NEO, UV 400, STEEL and BLACK series. Distributed across Indonesia through an authorized dealer network and its own Experience Center, Spectrum has built a strong social following on Instagram and TikTok, where content and click-to-chat campaigns drive a steady stream of enquiries into WhatsApp.

The problem: Managing WhatsApp conversations at scale

Spectrum's social presence generates significant interest, with high volumes of new leads per month from click-to-chat campaigns. However, operating on the standard WhatsApp Business App limited the team's ability to scale retargeting, track performance and manage responses.

Since the WhatsApp Business App caps broadcasts at 256 contacts at a time, the team couldn't re-engage its contact base at the volume it needed. Leads who came in from ads but weren't ready to tint their car that week simply went cold — and tinted their car elsewhere a month later.

Lead status lived in agents' heads and chat scrollback, leading to inconsistent follow-ups. The team also wasted time on unqualified enquiries: when a campaign performed well, spam and price-shoppers diverted focus from serious buyers ready to book. Different enquiry types — car owners wanting installation, customers booking an Experience Center visit, architectural project enquiries and workshops asking about dealership — all arrived in the same inbox with no automatic routing.

Finally, there was no after-hours coverage. Car owners researching tint options at night waited until the next morning for a reply, and many simply booked with whichever brand answered first.

The Aelyst solution

Spectrum adopted Aelyst, an AI-powered omnichannel CRM built for Southeast Asian businesses, connecting WhatsApp, Instagram and Facebook Messenger so all conversations, ad replies and broadcasts are managed in a single platform.

Automatically capture contact data and route leads

Aelyst's AI Agent identifies each enquiry from the first messages — retail installation, Experience Center booking, architectural project or dealer interest — and collects key details like car model, city and preferred series before routing the conversation to the right team member. Contact records are enriched automatically, so the team never has to re-ask basics, and city data lets them direct customers to the nearest authorized dealer instantly.

Handle after-hours conversations and lead qualification with AI

The AI Agent greets prospects around the clock, answering FAQs about series differences (NEO vs UV 400 vs STEEL vs BLACK), pricing, warranty and heat-rejection performance in natural Bahasa Indonesia — then gathers qualification details before handoff to the sales team. By managing routine questions and filtering out poor-fit leads and spam, the human team stays focused on serious buyers even during campaign-driven volume spikes. Night-time researchers get instant, accurate answers instead of silence — so Spectrum is the brand that replied first.

Send retargeting broadcasts at scale

Aelyst's throttled broadcast engine removes the 256-contact ceiling, so Spectrum now reliably sends [20,000+] targeted WhatsApp broadcasts per month. Broadcasts are segmented by lifecycle stage and tags, so each contact receives follow-ups matched to where they are in the journey: unclosed quotes get a promo nudge, Experience Center visitors get a booking reminder, and past customers get offers on architectural film for their homes — turning one install into multiple sales.

Know which campaigns produce installations, not just chats

With every conversation flowing through Aelyst's lifecycle stages — from new enquiry to quote sent to installation booked — the team finally sees which campaigns and content produce paying customers rather than just enquiry volume. Reports on conversation trends and drop-off points guide where to put ad spend, keeping lead quality rising while volume stays high.

"With Aelyst, WhatsApp became a true performance channel for us. The AI Agent handles the flood of enquiries from our campaigns without sacrificing quality, and lifecycle-targeted broadcasts brought back leads we would have lost entirely — delivering a [42.5x] return on what the platform costs us."

— Tom, Marketing Director of Spectrum Window Films

The results

Since implementing Aelyst, Spectrum reliably broadcasts [20,000+] targeted WhatsApp messages every month, fueling consistent re-engagement of leads who weren't ready to buy on first contact. Automatic routing keeps conversations relevant from the first reply, and the AI Agent takes care of qualification so the team can prioritize buyers ready to book.

Most notably, targeted WhatsApp broadcasts achieved a [42.5x] ROI on platform costs, and lifecycle-driven follow-ups delivered [10%] more conversions. By unifying Instagram, WhatsApp and Facebook Messenger into a single inbox and automating the early stages of every chat, Spectrum now handles campaign-season surges with confidence while converting more prospects into installed customers.
