Marketing and sales tools are only as good as the channels and data they connect to. Start with coverage: does the tool handle the work you actually do — email, social, ads, SEO, outreach — or just one slice? Integrations with your CRM and analytics decide whether it becomes a system or another silo, and reporting should show business results, not vanity metrics. For AI content features, check output quality and brand-voice controls; for outreach, deliverability and personalisation depth matter more than send volume. Be wary of tools that promise automatic growth: the durable wins come from faster testing, better targeting and cleaner follow-up, all of which still need your judgement on top.
