Apollo.io: What Users Say
Most users appreciate Apollo.io for its extensive database and multi-channel capabilities. Sales reps love the control they get over prospect filtering, outreach cadences, and CRM integrations.

AiSDR: What Users Say
AiSDR users often highlight how effortless it is to get started. The AI-generated emails are frequently described as “surprisingly human-like,” which increases open and reply rates. Lead scoring based on intent helps teams focus only on those most likely to convert.
On the downside, some users feel detached from the messaging process, as the AI takes over most of the content creation. It’s not ideal if your team wants granular control over tone, structure, or messaging. Also, the premium pricing makes it more suitable for well-funded or scaling sales teams.
