Why it ranks #4
One of the most frequently included sales-engagement platforms in major cold-email roundups, with a very large G2 review footprint and a proprietary B2B database that pure senders do not match.Here is the catch

less specialized deliverability control than cold-email-only tools
Does this well
combines prospect data and outreach in one system
large database and strong filtering
broad CRM and sales-tool integrations
