#1 Apollo.io 88/100 Best B2B Prospecting
Apollo gives you a 275M+ contact database, email sequencing, and AI-powered engagement scoring in one platform. The free plan includes 50 email credits per month — enough to validate the tool before upgrading. AI features include intent signal detection, email personalisation, and suggested outreach timing.
Free plan: Yes (50 email credits/mo) | Paid from: from $49/mo
#2 HubSpot CRM 93/100 Best Sales CRM
HubSpot’s Sales Hub goes far beyond CRM — automated email sequences, meeting booking, call recording, deal pipeline management, and Breeze AI all work together on the same contact record. For small sales teams that want one tool to manage the full cycle, nothing beats the free starting point.
Free plan: Yes — unlimited users | Paid from: from $20/user/mo
#3 Instantly.ai 87/100 Best Cold Email Volume
Instantly is purpose-built for sending large volumes of cold email with excellent deliverability. Unlimited sending accounts, AI-powered warm-up, and a clean sequence builder Make it the go-to for agencies and founders running high-volume outbound. The AI personalisation feature generates custom opening lines from prospect LinkedIn profiles.
Free plan: No (trial available) | Paid from: from $37/mo
#4 Lemlist 85/100 Best Personalised Outreach
Lemlist pioneered personalised cold outreach — dynamic images, custom landing pages, and multi-channel sequences (email + LinkedIn + phone). AI features include personalised icebreaker generation and smart sending times. It is pricier than Instantly but offers more personalisation depth and LinkedIn automation.
Free plan: No (trial available) | Paid from: from $59/mo
#5 Hunter.io 84/100 Best Email Finder
Hunter is the simplest way to find verified professional email addresses at scale. Enter a domain and get all associated emails with confidence scores, or search by name and company. The verification API integrates with most outreach tools to keep bounce rates low before sending.
Free plan: Yes (25 searches/mo) | Paid from: from $49/mo
#6 Close 86/100 Best Outbound CRM
Close combines CRM, built-in VoIP calling, SMS, and email sequences in one platform — eliminating the need for a separate dialler. For outbound sales teams, having calls logged automatically and AI-generated summaries immediately after each call accelerates follow-up significantly.
Free plan: No (14-day trial) | Paid from: from $49/mo
What to Look for in an AI Sales Tool
The best AI sales tools earn their keep on five dimensions: a large and accurate prospecting database, strong email deliverability infrastructure, AI-driven personalisation that goes beyond mail-merge, clean CRM integration to avoid double-entry, and transparent per-seat or usage-based pricing that scales with a small team.
Frequently Asked Questions
What AI tools do top sales teams use?
High-performing small sales teams typically combine a prospecting tool (Apollo or Hunter) with an outreach sequencer (Instantly or Lemlist) and a CRM (HubSpot or Close). The combination costs less than $150/month and replaces what used to require multiple full-time SDRs.
What is the best free sales tool?
HubSpot’s free CRM is the most complete free sales tool available — it includes deal pipelines, email tracking, meeting scheduling, and basic sequences. Apollo’s free plan adds prospecting data. Both can be used together at no cost to get a functional outbound sales workflow.
Instantly.ai vs Lemlist — which is better?
Instantly wins on volume and deliverability — it is better if you are sending thousands of emails per month and need reliable inbox placement. Lemlist wins on personalisation and multi-channel sequences, especially if LinkedIn outreach is part of your workflow. If budget allows, many teams use both for different campaign types.
