Unless you’ve already hit unicorn status, lead generation is going to be a grind. That’s just how it works. You’re out there competing for attention, time, and inbox space, and your clients are counting on you to win.
Sure, anyone can learn to do lead gen. But if they’ve hired you, they expect results. That means no random outreach, no broken workflows, and definitely no outdated tools.
You need the kind of tools that actually help you start conversations, track intent, and move people forward.
That’s what we’re here for.
In this guide, we’re breaking down the five tools trusted by the agencies who do this at scale.
Pricing for SaaS tools like these changes frequently. We re-checked every price below on the vendor’s own pricing page in October 2026. Check those pages before you buy, because plans and prices can change at any time.
1. Instantly
Cold email isn’t dead. It’s alive, kicking, and still one of the most profitable channels lead gen agencies rely on, especially when you’re using the best tool for the job.
Instantly combines cold outreach and lead sourcing into one scalable platform. Agencies use it to send personalized cold emails at scale and tap into a massive B2B database of over 450 million contacts. Instead of jumping between tools, everything happens in one place: lead search, warm-up, inbox rotation, campaign tracking, and even AI-assisted prospecting.
The interface is clean, fast, and made for speed. Need to manage 10+ client accounts? No problem. You can add unlimited email accounts under one subscription, automate warmups, and reach thousands of inboxes without going to spam.
Pros:
- All-in-one lead gen and cold email tool
- AI-powered lead search and campaign suggestions
- Excellent deliverability with automatic warm-up
- Unlimited email accounts
- Intuitive UI and powerful analytics
- Works with most tech stacks
- Scalable for small teams or large agencies
Pricing:
Outreach plans start at $47/month (Growth, billed monthly), with discounts for annual billing. Access to the lead database is sold separately as monthly credit plans (Instantly pricing).
2. Dripify
While it’s best known for LinkedIn campaigns, Dripify also helps agencies run cold email sequences that feel human, not robotic.
You can build multi-step drip campaigns using delays, triggers, and conditions that adapt to how prospects respond. That means your follow-ups will land at the right time, with the right message. Agencies can also manage full teams inside Dripify, assign roles, and track progress in one shared space.
Need verified email addresses? Dripify’s built-in enrichment and verification tools make that easy too. It also plays well with popular CRMs like HubSpot and Salesforce, so you don’t have to waste time syncing data.
And yes, it’s cloud-based, so your campaigns keep running even when your laptop’s off.
Pros:
- Combines LinkedIn and email outreach
- Powerful multi-step campaign builder
- Built-in email finder and verifier
- Easy CRM integrations
Cons:
- LinkedIn focus may be too niche for some
- Limited email volume on lower tiers
Pricing:
The Pro plan costs $79 per user per month, or $59 per user per month billed annually, and the Advanced plan costs $99 ($79 billed annually). A 7-day free trial is available (Dripify pricing).
3. Clay
Lead gen agencies can use Clay to pull enriched data from more than 150 providers, including funding news, tech stack, and buyer intent. That means more accurate targeting and far better results when running cold email campaigns.
What really sets Clay apart is its AI assistant. It can auto-generate personalized messages using the data it collects. It also supports flexible lead scoring, so you always know which contacts are worth chasing.
While Clay doesn’t send emails on its own, it plugs right into CRMs and email tools, streamlining the entire workflow.
Pros:
- Access to 150+ data providers for deep prospect insights
- AI-generated personalized outreach at scale
- Custom lead scoring and segmentation
- Seamless CRM and tool integrations
Cons:
- Doesn’t handle actual email sending
- Takes time to master advanced workflows
Pricing:
Clay has a free plan. Paid plans start at $185/month for Launch ($167/month billed annually), and Growth costs $495/month. Prices scale with usage, and larger agencies can get custom Enterprise plans (Clay pricing).
4. Waalaxy
Similar to Dripify, Waalaxy blends cold email and LinkedIn automation into one platform, letting you run multichannel campaigns from a single dashboard. Note that cold email sequences are only included in its Business plan.
Its biggest strength lies in building sequences that blend LinkedIn steps with cold emails, so your outreach feels natural and stays consistent across channels. It also comes with pre-built templates to get campaigns off the ground fast, which is great for agencies working with multiple clients.
Waalaxy also offers an inbox for managing your LinkedIn conversations in one place, which helps when you are handling many conversations. It is sold as a paid add-on rather than included in the plans.
Pros:
- Multichannel LinkedIn + email campaigns (Business plan)
- Ready-to-use templates
- Inbox for LinkedIn conversations (paid add-on)
- Easy to use with a clean interface
Cons:
- More suited for smaller agencies or teams
- Email customization options are a bit limited
Pricing:
Plans cost €19 (Pro), €49 (Advanced) and €69 (Business) per user per month, with discounts for quarterly and yearly billing and a 14-day free trial. Cold email features need the Business plan, and the inbox is an add-on at €20/month (Waalaxy pricing).
5. Klenty
Klenty is a sales engagement platform that supports multi-channel outreach (email, LinkedIn, and calls), so agencies can reach prospects where they’re most active. But if you only want to run cold email campaigns, there’s a dedicated plan for that.
For agencies managing several clients, Klenty’s behavior-based cadences take the pressure off by automatically following up based on prospect activity. Its deep integrations with CRMs like Salesforce, HubSpot, and Pipedrive make it easy to keep everything updated and connected.
The AI-generated conversation summaries help teams pick up insights faster, which is great for fast-moving agencies that want to stay on top of their game.
Pros:
- Flexible cold email–only and multichannel plans
- Behavior-based automation
- AI-powered call and email summaries
- Clean UI and solid CRM integrations
Cons:
- Reporting can be hit or miss
- Advanced features may take time to master
Pricing:
The cold-email-only Starter plan costs $50 per month billed annually, with unlimited users and mailboxes. The multichannel Growth and Plus plans cost $70 and $99 per user per month, billed annually (Klenty pricing).
