Review Apollo.io?
Reviewers mostly see Apollo.io as a practical all-in-one tool for prospecting and outbound: it saves lead research time, centralizes data, list building, CRM sync, and sequencing, and its filtering is repeatedly praised as a standout strength. Some users also find it easy to set up and use. But the weak point comes up often: data quality is uneven, with bounced or outdated emails, thinner coverage outside tech or in markets like India, and reporting or sequencing that could be smarter. A few reviews also sharply criticize account lockouts, refund policy, and support.

Customer.io is the customer engagement platform built for lifecycle marketing, with segmentation, behavioral triggers, and multi-channel messaging across email, SMS, push, and in-app all in one place. We chose it because it lets you send based on what customers actually do, not just a schedule, and the IFTTT integration means real-world activity can feed directly into your campaigns.
I've been an Apollo power user for 5 years, bringing it to every GTM team I've joined since, so this feature is an amazing addition! Congrats on the launch team
Apollo powers our creator outreach. Finding and reaching the right newsletter writers and podcasters would take forever without it. The enrichment data is what makes it work.
