How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Apollo is the value pick for teams that want contact data and sequencing in one login. The free plan covers light prospecting, and paid starts at $49 per user per month.
- Outreach and Salesloft are the enterprise choices. Both keep pricing behind a sales call and neither offers a free trial, so expect a real contract and an implementation project.
- Smartlead, Instantly and Woodpecker compete on inbox rotation and deliverability for high-volume cold email, with entry prices between $29 and $47 a month.
- Clay plays a different game. It researches and enriches leads with AI agents instead of sending emails, and its free plan is generous enough to test real workflows.

The best outbound GTM software

Apollo
Best for: teams that want data and sequencing in one place
Visit apollo.io
Starting price$49 per user/month (billed annually)
Free planYes
Apollo is the first tool most small teams try, and usually the last one they need to switch away from. The pitch is simple. You get the contact database and the engagement platform under one roof, so reps stop juggling a data vendor and a sequencer. Search filters cover titles, headcount, tech stack and buying signals, and you can push matched contacts straight into a sequence without exporting a CSV.
The honest catch is data quality. Apollo's database is wide rather than perfect, so niche industries and non-US markets need spot-checking before you burn domains on bad addresses. Teams that treat Apollo as a starting point and verify high-value contacts separately get the best results. For the price, the free plan is genuinely useful for a founder doing their own prospecting, and Basic is hard to beat when you compare it with buying data and sequencing separately.
What we like- Large built-in B2B contact database with email verification
- Sequences, dialer and LinkedIn steps in one workflow
- Free plan includes monthly credits for testing
Watch out for- Contact accuracy varies by industry and region
- Conversation intelligence and deeper analytics cost extra
- The $49 rate requires annual billing
Starting priceSee website
Free planNo
Outreach rebranded from outreach.io to outreach.ai in 2026, which tells you where the product is headed. The platform now leans hard on AI agents that handle follow-up drafting, call summaries and next-best-action suggestions. For large teams running hundreds of SDRs, the analytics layer alone justifies the cost. Managers can see exactly which sequences, templates and reps produce pipeline.
This is not a tool you buy on a credit card on a Friday afternoon. There is no trial, pricing requires a sales conversation, and you will want an admin who owns the instance. Smaller teams should be honest about whether they need this much machinery. If your team is under twenty reps, one of the cheaper options below will get you replies without the overhead.
What we like- Mature platform with deep Salesforce integration
- AI agents that draft, prioritize and summarize
- Strong reporting for large SDR teams
Watch out for- Pricing is quote-only and runs about $100 to $150 per user per month in practice
- No free trial
- Implementation takes real admin effort

Salesloft merged with Clari in late 2025, creating a combined sales execution and forecasting company. On the product side, not much changed for daily users. The cadence builder remains the reference point competitors copy, with branching logic based on opens, replies, call outcomes and stage changes. Conversation intelligence captures calls and surfaces coaching moments without a separate tool.
Pricing sits in the same band as Outreach, with Essentials, Advanced and Premier tiers and dialer capacity sold separately. Like Outreach, there is no trial, so you evaluate through a demo and reference calls. Teams already on Clari for forecasting get an obvious reason to consolidate. Everyone else should compare both platforms on the same checklist before signing a multi-year deal.
What we like- Best-in-class cadence and workflow engine
- Strong conversation intelligence
- Merger with Clari adds revenue forecasting depth
Watch out for- Quote-only pricing with tiered plans
- Admin complexity grows with team size
- Dialer minutes billed as an add-on
Starting price$79 per user/month

Lemlist built its name on personalization at scale, and the product still leads there. Custom images, videos and dynamic landing pages per prospect sound gimmicky until you see reply rates on well-targeted lists. The deliverability side is equally serious. Automated warm-up, inbox rotation and spam testing come standard, which matters more than any personalization trick when Gmail and Outlook tighten their filters.
The tradeoff is price structure. Email Pro at $79 per user per month is fair for one rep, but a ten-person team pays real money before adding the multichannel tier. Agencies like the per-client workspaces, which keep campaigns separated cleanly. Solo founders may find Smartlead or Instantly cheaper for pure cold email volume.
What we like- Built-in email warm-up and deliverability toolkit
- LinkedIn voice notes and call steps in multichannel plans
- Good agency features with client workspaces
Watch out for- Per-user pricing climbs quickly with team growth
- The cheapest plan is email-only
- AI personalization add-ons increase the bill
Starting price$49 per user/month (billed annually)

Reply sits between the budget cold email tools and the enterprise platforms. The Email Volume plan at $49 per user per month undercuts Lemlist while adding LinkedIn and call steps on the Multichannel tier. Jason, its AI SDR assistant, drafts responses and can handle routine back-and-forth, which saves reps from the inbox grind that kills most outbound programs.
Where Reply loses points is simplicity. New users face a dense interface with more toggles than they expect, and the first week involves real setup. Teams that push through get a capable system at a mid-market price. Teams that want something running in an afternoon should look at Instantly instead.
What we like- Jason AI assistant drafts and handles replies
- Email, LinkedIn, calls and SMS in one sequence
- Verified B2B data included
Watch out for- The interface packs a lot in and takes time to learn
- AI features are strongest on higher tiers
- Call and SMS add-ons are billed separately
Starting price$39/month ($32.50 billed annually)
Free planFree trial (14 days)
Smartlead is the tool cold email agencies recommend to each other. The core idea is inbox rotation. You connect many mailboxes, spread sending across them, and keep per-mailbox volume low enough to protect your domains. Unlimited warm-up keeps new inboxes healthy before they send a single campaign email.
Pricing is the other draw. Base at $39 a month, dropping to $32.50 on annual billing, buys serious sending capacity for the price of one Lemlist seat. The product is less polished than the tools above it, and reporting will not satisfy an enterprise RevOps team. For pure outbound email volume with deliverability handled properly, few tools match the value.
What we like- Unlimited mailboxes and warm-up on higher plans
- Strong deliverability reputation among cold email agencies
- Affordable as sending volume grows
Watch out for- Support is mostly chat-based
- Analytics are thinner than enterprise platforms
- Advanced features sit behind higher tiers
Starting price$47/month ($37.60 billed annually)
Free planFree trial (14 days)
Instantly won the speed race in cold email software. Connect a domain, warm it up, load a list and launch, all in one sitting. The warm-up network is one of the largest in the category, which helps new domains build sender reputation faster. A built-in lead database add-on means you can go from zero to a sending campaign without a separate data subscription.
The simplicity has limits. Teams that outgrow basic reporting or need deep CRM workflows eventually graduate to something heavier. Instantly knows this and prices accordingly, keeping the entry point low and charging for volume. For founders and small agencies that need pipeline this month, that tradeoff is easy to accept.
What we like- Setup takes minutes, not days
- Large warm-up network included
- Built-in lead database add-on for list building
Watch out for- Analytics are basic compared with Salesloft or Outreach
- Sending limits scale with plan price
- Some advanced deliverability controls need higher tiers
Starting priceFrom $29 per slot/month

Woodpecker's slot pricing is its superpower for agencies. Instead of paying per user, you pay per sending slot and rotate clients through them. A three-person agency running campaigns for twelve clients pays a fraction of what per-seat tools would charge. Conditional logic, often called "if campaigns," routes prospects down different paths based on behavior without manual work.
The product shows its age in places. The interface is functional rather than delightful, and native integrations are thinner than what Lemlist or Reply offer. Woodpecker compensates with reliability and a support team that actually answers. Agencies that care about margin per client will forgive the dated UI.
What we like- Pay per sending slot instead of per user
- Strong conditional logic and A/B testing
- Agency-friendly client separation
Watch out for- Fewer native integrations than newer competitors
- Interface feels dated
- LinkedIn automation needs workarounds
Starting price$600/month (billed annually, 2 users included)
Free planFree trial (14 days)
Amplemarket sells the all-in-one story for teams that have outgrown point tools. Contact data, multichannel sequencing, an AI copilot that drafts outreach, and buying signals that trigger campaigns automatically. The Startup plan at $600 a month includes two users, which puts it between Apollo and the enterprise platforms on price.
The minimum commitment is the filter. This is not a tool for a solo founder testing outbound. It fits funded startups and mid-market teams that want one vendor for data and engagement with AI doing the repetitive work. Evaluate it against buying Apollo plus a sequencer separately before committing to the annual contract.
What we like- Data, sequencing and AI copilot in one platform
- Strong buying-signal triggers
- Good fit for teams of 5 to 50 reps
Watch out for- $7,200 annual starting commitment is steep for small teams
- Annual billing required for the Startup rate
- Fewer mailbox options than pure cold email tools

Clay
Best for: AI-powered lead research and enrichment
Visit clay.com
Starting priceFree, paid from $185/month
Free planYes
Clay is the only tool on this list that does not send a single email. It finds your prospects, enriches them from dozens of data sources, uses AI to research each company, and hands a scored, personalized lead list to whatever sequencer you use. Teams that run Clay plus Smartlead or Instantly get the best of both worlds. Great data feeding a great sending engine.
The 2026 pricing overhaul moved Clay to a credits plus actions model. The free plan is genuinely useful, and Launch at $185 a month covers serious volume. The catch is complexity. Clay rewards users who invest time in learning its table-based workflows, and credit consumption needs monitoring. Used well, it replaces three or four data subscriptions at once.
What we like- Waterfall enrichment across 100-plus data providers
- AI agents that research companies and score leads
- Generous free plan for testing
Watch out for- Real learning curve for new users
- Credit-based pricing can surprise heavy users
- It does not send emails, so pair it with a sequencer
How we chose
We compared platforms on the factors that decide outbound results: deliverability infrastructure, data quality, pricing transparency, and how much of the workflow each tool covers. We read current pricing pages, product documentation, and public reviews on G2, Capterra and Reddit, and we checked which tools fit teams of different sizes rather than ranking by brand fame. No vendor paid for placement, and we did not claim hands-on testing. The write-ups above reflect what each product actually sells and where buyers report friction.
What to check before you buy
A demo never shows you the parts of outbound software that matter most. Ask about these four areas before you sign anything.
Deliverability infrastructure
Your emails are worthless in spam. Ask how the tool handles warm-up, inbox rotation, SPF and DKIM setup, and bounce handling. Tools like Smartlead and Instantly built their reputations here. Enterprise platforms assume your IT team handles domain setup, which is fine if you have one.
Data quality and enrichment
Bad data burns domains and rep time. Ask where contact data comes from, how often it is verified, and what happens with bounced addresses. Apollo and Clay take opposite approaches, one with a built-in database, the other with waterfall enrichment, and both beat buying static lists.
Pricing model traps
Per-user, per-mailbox, per-slot and credit-based pricing behave very differently as you grow. A $39 tool that charges per mailbox can cost more than a $79 per-user tool once you connect twenty inboxes. Model your real setup, including annual versus monthly billing, before comparing sticker prices.
CRM and workflow fit
Outbound software that does not sync cleanly with your CRM creates manual work that kills adoption. Check native integrations with Salesforce or HubSpot, how activities log, and whether sequences can trigger from CRM stages. This is where Outreach and Salesloft justify their price for larger teams.
Three pricing models dominate this category, and each favors a different buyer. Per-user pricing from Lemlist, Reply and Apollo is simple to budget but punishes team growth. Per-mailbox and volume pricing from Smartlead and Instantly rewards high-volume senders and agencies. Credit-based pricing from Clay charges for enrichment actions, which is fair until a messy list burns credits on bad matches.
Annual billing discounts run 15 to 25 percent across the category, but they lock you in before you know if the tool fits. Start monthly where the option exists. Watch for add-ons too. Dialer minutes, phone verification credits and AI features often sit outside the base price, and they are where the real cost hides on enterprise contracts.
Frequently asked questions
What is outbound GTM software?
It is software that helps sales teams find prospects and contact them through email, phone, LinkedIn and SMS. The category covers sales engagement platforms, cold email tools, contact databases and AI enrichment tools. Most teams combine two or three of these rather than buying one product.
How much does outbound software cost?
Budget tools start around $29 to $49 a month. Mid-market options run $79 to $185 per user per month. Enterprise platforms like Outreach and Salesloft are quote-only and typically land between $100 and $150 per user per month before add-ons.
Will cold email hurt my domain reputation?
It can if you send high volumes from a new domain without warming it up. Use a separate domain for outbound, warm up inboxes gradually, keep bounce rates under 2 percent, and rotate across multiple mailboxes. Tools with built-in warm-up and rotation make this far easier.
Do I still need a separate data provider?
It depends on the tool. Apollo and Amplemarket bundle contact data. Clay enriches data from many providers. Smartlead, Instantly and Woodpecker expect you to bring your own lists. If your target market is niche, budget for a data source even with an all-in-one tool.
Outreach or Salesloft, which should I choose?
Both serve enterprise teams well and pricing is comparable. Outreach leans into AI agents and analytics, while Salesloft, now merged with Clari, offers stronger cadence workflows plus forecasting. Run the same evaluation checklist on both, talk to reference customers in your industry, and negotiate the contract length.
