Lead411 does not offer a permanent free version but provides a free trial for evaluation. The entry-level Spark Annual plan starts at $490.00 per year and includes 12,000 contacts, verified emails, advanced search, and a Chrome extension, but lacks phone numbers, CRM customizations, and intent data. Lead411's Ignite Annual tier adds unlimited verified emails, unlimited direct mobile dials, AI search, company news updates, and CRM integrations. Lead411's Blaze Annual tier further unlocks unlimited exports, Bombora intent data, tech stack search, lead scoring, international search, currently hiring data, and a dedicated support manager. G2 reviewers note that phone numbers and CRM integrations are key upgrade drivers.
