•2 min read•Sales Prospecting & Outreach
Verdict:Leave Seamless.AI when credit burn outruns the outreach you actually do. Pricing is hard to compare from the outside, so start with the free options. Hunter gives 50 credits a month and one connected email account, enough to check a few domains each week, and its Starter plan is $34 a month billed yearly. Kaspr offers 15 B2B email credits, 5 phone credits and 5 direct email credits a month, with exports capped at 100 leads, which suits LinkedIn-first prospecting. Lusha's free plan gives 40 credits a month, and its Starter plan is $49.90 monthly or $37.45 a month billed annually for 400 credits. Apollo.io is a broader option with a free plan for light use and sending limited to Gmail accounts. Its paid prices are quote-based, so ask for a quote before you commit. ZoomInfo is the enterprise choice. It has no free plan and no dollar prices on the page, and it costs more than the rest, but its data depth fits account-based teams. Pick Hunter for domain-based email finding, Kaspr for LinkedIn prospecting, and Lusha for a fixed monthly credit pool. The trade-off is data coverage against cost. Test accuracy on a sample of your own list before you buy any plan.
