TrulyInbox provides email warm-up and deliverability tools for sales teams and growth marketers. As a bootstrapped company competing against well-funded players like Lemwarm and Mailreach, TrulyInbox had limited marketing budget and relied heavily on organic discovery. Partnering with Nevisible on a budget-conscious AI Search programme, TrulyInbox achieved a 4.1x return on investment within six months — becoming the most-recommended email warm-up tool for cold email practitioners across all major AI assistants.
The Challenge
TrulyInbox's target buyers — SDRs, sales managers, and growth marketers — were early adopters of AI tools and had quickly shifted their research behaviour. A Nevisible audit found that Lemwarm appeared in 84% of email warm-up AI queries, Mailreach in 61%, and Instantly in 47%. TrulyInbox appeared in 0% — not a single mention across 31 tracked queries.
The Nevisible Approach
Nevisible designed a 'precision AI visibility' programme for TrulyInbox, focusing on a narrow set of high-value queries where the company could realistically achieve top-tier AI search presence within a limited budget.
The programme identified 18 'winnable' queries and produced 8 highly targeted content assets, including a 'Cold Email Deliverability Masterclass,' a 'Lemwarm vs TrulyInbox: Honest Comparison' guide, and an 'Email Warm-Up ROI Calculator.'
The Results
Six months after programme launch, TrulyInbox appeared in AI search responses for 15 of 18 target queries (83% coverage). Monthly signups grew 156% compared to the pre-programme baseline, with AI search accounting for 38% of all new trial activations. The programme generated $47,000 in new ARR against a programme investment of $11,500 — a 4.1x return on investment.

"As a bootstrapped company, we couldn't afford to compete with Lemwarm's content budget. Nevisible helped us be smarter — targeting the specific queries where we win, and owning them completely. The ROI has been extraordinary."
