How Mail-Lead grows

3 tactics and 1 figures from 1 interview.

A basic cold email tool built by the team behind the automation product TaskMagic, Mail-Lead was one of several small, specific side products meant to solve customers' next problem and feed users back to the main product. It grew through its own search traffic and sales to existing customers, and brought in almost seven figures in revenue by itself.

Summary written 2026-09-26 from the tactics below. Figures are as founders stated them.

Mail-Lead's 3 tactics

TaskMagic · B2B · browser automation software

The cold email side tool made almost seven figures on its own and fed paid users back

'Tentpole strategy': instead of marketing the core product (TaskMagic) with free info content, sell functionality via small, cheap standalone products. Step 1: build for the core customer's next problem (TaskMagic's buyers were business owners, agencies and freelancers who need sales). Step 2: keep it very simple and specific, e.g. Mail-Lead, a basic cold email outbound tool, because specific products ('cold outreach email for some sector') rank faster on SEO than a general one. Sell it to existing customers and let its own SEO attract new ones. It is its own product, not a white-label.

Mail-Lead · B2B · cold email tool

Founder says it drove paid users into the main product; no separate numbers

Make sure each side product hits a natural upgrade path to the core. In Mail-Lead, once users want to connect it to other apps they use, they click the automation button/tab and land in TaskMagic, built in seamlessly. When they hit a limit there, they start paying for TaskMagic. Users often found Mail-Lead without knowing TaskMagic existed.

LeadQuest · B2B · lead search tool

Founder says the products help each other; no numbers for the lead tool

Last step of the tentpole strategy: ask what the side product's users need next. Mail-Lead users need leads to email, so they built LeadQuest (leadquest.ai) for lead search. From LeadQuest, the automation tab sends users to TaskMagic (e.g. auto-send found emails via Gmail), and users who want to mass-email their leads buy Mail-Lead. Jeremy says if he started over he would make LeadQuest the tentpole; the products are not separate side hustles but serve one ecosystem.
