The Best Outbound Email Tools

Cold email alone doesn't cut it anymore—prospects ignore inboxes but respond on LinkedIn, SMS, or calls. The winning play is multichannel. Here's how to pick the right tool.

Know Before You Start

Choosing the right tool is only half the battle. Here's what can derail your outreach before it starts.

  • Deliverability is the real game: 21% of B2B emails never reach inboxes due to poor domain/IP setup. Use secondary domains, warm up inboxes 2-4 weeks before scaling, and cap sending at 100-200/day per inbox.

  • "Unlimited emails" is misleading. Gmail and Outlook cap sending at 200-500 emails/day per inbox regardless of what your tool promises. Lemlist's built-in Lemwarm helps; Apollo's warmup is basic.

  • LinkedIn automation carries real risk. LinkedIn limits automations to 10-20 connection requests/day, so 50-100 messages is a safe target. Avoid automating outreach from executive LinkedIn profiles. Checkout this LinkedIn Automation Safety Guide.

  • GDPR applies to B2B cold outreach. If targeting EU contacts, you need "legitimate interest" (a real, relevant reason) for each person.

Start with one channel, nail your deliverability basics, then expand. Remember, a well-warmed inbox on any tool beats a cold one on the fanciest platform.
