B2B contact database, email sequencing, dialer and enrichment in one platform
Apollo is a category leader for B2B contact data and automated email sequencing, priced around a credit meter that charges you at the moment a contact leaves the platform.
Best for
Teams that want one subscription covering B2B contact data, enrichment and automated email sequencing.
Not great for
Teams whose main channel is LinkedIn, since Apollo's LinkedIn steps are task reminders a person completes by hand.

Apollo.io, in plain terms
Apollo.io is a go-to-market platform that combines a B2B contact database, email sequencing, a dialer, data enrichment and deal management in a single subscription. Its homepage claims 240M+ contacts and 30M+ companies, with 65+ search filters, and states that more than 600,000 companies use the product. Email sequencing is fully automated, with A/B testing, task reminders and multi-touch workflows. Higher tiers add a parallel dialer with call recording and transcription, Bombora-backed buying intent, website visitor identification and inbound lead routing. There is a free forever tier, an open REST API, a Chrome extension and an MCP server, plus an AI assistant for agentic workflows launched in March 2026. The most discussed friction is the credit system. Apollo charges one credit to reveal an email address, eight credits to reveal a mobile number and one export credit whenever a contact is exported outside Apollo, and unused credits do not roll over between billing cycles. Overage credits are $0.20 each with a 250 credit minimum purchase. Apollo is also not a LinkedIn sending tool: per its own knowledge base, LinkedIn steps inside a sequence are manual task reminders that a person completes by hand. Public ratings differ by platform, at 4.7 on G2 from roughly 9,300 reviews and 2.9 on Trustpilot from roughly 1,000 reviews, checked July 2026.

No. Per Apollo's own knowledge base, LinkedIn steps inside a sequence are task reminders. When the step fires, Apollo reminds the assignee to visit the profile, take the action by hand and then mark the task complete. Email sequencing is the automated channel.
Revealing an email address costs one credit, revealing a mobile number costs eight, and exporting a contact outside Apollo costs one export credit. Credits do not roll over at the end of a billing cycle, and overage credits are $0.20 each with a 250 credit minimum purchase, from their published pricing, July 2026.
Yes. Apollo publishes a free forever tier with a small monthly credit allocation, and trial plans include 50 credits and 5 mobile credits with most features of the selected plan.
Apollo's homepage states 240M+ contacts and 30M+ companies, searchable with 65+ filters. Some third party write-ups cite a higher figure from an earlier count.
The two recurring themes in public reviews are credit consumption and data accuracy on exported contacts. Ratings differ by platform, at 4.7 on G2 from roughly 9,300 reviews and 2.9 on Trustpilot from roughly 1,000 reviews, checked July 2026.
One of these tools is ours.
