Seamless.AI
Sales teams that want a large contact database plus built-in emailing and dialing, and are fine negotiating a custom quote.
Quick overview
- Pricing
- Free plan with 50 credits; paid plans are quote only (no public prices)
- Plans
- Seamless.AI publishes no paid prices. The pricing page (checked 2026-10-17) is a contact-sales form that asks how many contacts you need per month and your company size, and says it offers volume discounts, unlimited users on custom deals, no setup fees and switch discounts of up to 50% of a competitor's remaining contract value. The homepage FAQ says Seamless.AI is free for up to 50 credits; it does not say whether those credits refresh.

Apollo.io alternatives
Lusha is the easiest self-serve swap for small teams: a free plan, public prices and phone numbers at 5 credits instead of Apollo's 8. Pick Cognism for European calling, Hunter if you only need emails, Clay for custom enrichment, or lemlist if you mainly want better sequences. Larger teams that need more data and intent should look at ZoomInfo.
