- Professional — $79/user/mo billed annually — higher credit limits, AI features, call recording and advanced CRM integrations
- Custom — price on request — custom volumes, SSO, advanced admin controls and dedicated support
Small and mid-sized sales teams that want prospect data, AI-written outreach and sequences without buying separate tools.
Teams that need consistently accurate mobile numbers at volume, since phone lookups use many credits and users report gaps in contact data.
How it scored
- AI outreach & personalization: 90/100. Its AI covers research, list building, email drafting and behavior-based sequences, giving it one of the broadest AI toolsets on the page.
- Lead data & deliverability: 90/100. Its large built-in database covers email and phone with warm-up and mailbox tools, though users regularly report outdated contact details.
- Value: 80/100. Paid seats start low for a combined data and outreach tool, but expiring credits and costly phone lookups raise the real cost.
- Privacy & reliability: 70/100. Third-party AI providers may not train on customer data and must delete it within 30 days, but Apollo may train its own models on usage data with no stated opt-out.
- Expert & User Ratings: 90/100. Reviewers often rank it first for sales prospecting, and users rate it highly across thousands of reviews.
Our verdict
Apollo.io ranks first: it combines a large contact database, AI that researches leads and writes personalized emails, and multi-step sequences in one tool at a low entry price. Users regularly report outdated contact details, and phone lookups and expiring credits push up the real cost.
- Database, AI writing and sequences in one platform
- Low entry price compared with enterprise sales platforms
- Broad AI help, from list building to meeting prep
- Users report outdated or inaccurate contact details
- Phone numbers use many more credits than emails
- Unused credits expire at the end of each billing cycle
- Credits are pooled across the team and granted at the start of each billing cycle; unused plan and add-on credits expire and do not roll over.
- Add-on credits renew automatically each billing cycle until removed, and annual plans cannot be downgraded mid-cycle.
- Monthly billing costs more per seat than the annual prices shown, and credits also pay for email warm-up, domains and mailboxes.

How it scored
- AI outreach & personalization: 90/100. Its AI research agents and signal-based personalization are among the most flexible on the page, though building workflows takes skill.
- Lead data & deliverability: 90/100. Combining many data providers gives broad email and phone coverage, and a native sequencer with mailbox purchases now covers sending.
- Value: 70/100. Unlimited seats help larger teams, but paid plans start high and heavy enrichment uses credits fast.
- Privacy & reliability: 70/100. It says customer data is never used to train its or its AI providers’ models and holds SOC 2 certification, but it has had several service problems in 2026.
- Expert & User Ratings: 80/100. Reviewers often recommend it for lead research and enrichment, and users rate it highly.
Our verdict
Clay ranks second: its AI research agents and enrichment from many data providers let teams build highly targeted, research-driven outreach, and it now includes its own sequencer. It takes real skill to set up, paid plans start high, and it had a two-week enrichment slowdown in late 2026.

- Unlimited seats on every plan
- Steep learning curve for building tables and workflows
- Credits and actions can run out quickly on large lists

- Buying domains and mailboxes for the built-in sequencer starts on the Growth plan.
- Enterprise plans require an annual commitment.
- Price change: Clay introduced new plans on March 11, 2026; existing self-serve customers could keep their plans, while Enterprise contracts move to the new pricing at renewal.

Teams that want LinkedIn and phone steps in the same sequence, or one plan that bundles sending, data and AI.
How it scored
- AI outreach & personalization: 80/100. AI agents that answer replies and source leads add real automation to strong sequencing, though reviewers note the advanced AI costs extra.
- Lead data & deliverability: 90/100. Unlimited mailboxes, built-in warm-up and a large lead database with verification make it strong for email volume, though it is email-first.
- Value: 80/100. Flat pricing with unlimited accounts and users is good value for sending, but data and AI credits add a second bill.

- Expert & User Ratings: 90/100. Reviewers regularly include it among the top cold email tools for scaling, and users rate it very highly.
Our verdict

- Outreach plans and credits plans are separate subscriptions; finding leads and running AI agents draws on credits, at 5 credits per lead or reply for the AI agents.
- The uploaded-contacts limit is usually reached before the monthly email limit; extra outreach volume is an $87/mo add-on.
- You need your own sending domains and mailboxes, which should be warmed up before campaigns start.

- Unlimited Prime — $379/mo or $314.60/mo billed annually — 500,000 emails per month, private sending infrastructure, 3 client workspaces
Agencies and outbound teams that send large volumes of email from many mailboxes and want low per-email costs.
Teams that want AI to write and personalize their outreach or run LinkedIn-led sequences.
How it scored
- AI outreach & personalization: 70/100. Its AI sorts replies, assists with campaign setup and automates routine tasks, but does less to research prospects or write personalized messages than leading rivals.
- Lead data & deliverability: 80/100. Unlimited mailboxes, inbox rotation, warm-up and private servers support heavy sending, with a lead finder and dialer as extras.
- Value: 80/100. Low entry prices and unlimited mailboxes give good sending value, though agency add-ons add up.
- Privacy & reliability: 80/100. It names OpenAI and Anthropic as its AI providers, though it does not explain in detail how its AI features use customer data.
- Expert & User Ratings: 70/100. Users rate it well overall, though it appears less often in expert lists than the leading cold email tools.
Our verdict
Smartlead ranks ninth: unlimited mailboxes, inbox rotation and agency tools make it good value for very high sending volumes. Its AI focuses on sorting replies and automating tasks rather than writing personalized outreach, and add-ons raise the cost.
- Unlimited mailboxes and warm-up on every plan, with no long-term contract
- Strong tools for agencies, such as client workspaces and private sending servers
- Low entry price for the sending volume included
- AI is lighter on writing and personalization than outreach-focused rivals
- Many add-ons, such as client workspaces, servers and placement tests, raise the real cost
- Some users report slow support and billing problems
- Client workspaces cost $29/mo each, dedicated servers $39/mo each, and placement testing $49–$599/mo.
- Verified-email credits are an add-on on Base and Pro ($59/mo) and included from Unlimited Smart upward.
- You need your own domains and mailboxes, or can buy them through Smartlead at $4.50–$9 per mailbox per month plus domain fees.

Detailed Analysis
Key features
- Cadence for multi-step email and call sequences with email tracking
- Rhythm, which uses AI to prioritize each rep’s next actions
- AI agents and conversation intelligence that capture insights from calls
- Deals and Inspect tools for pipeline review, plus Clari Forecast
- Analytics and native Salesforce integration
Pricing
- All plans — price on request — quotes are given after a call with sales
- Platform modules — price on request — Cadence, Conversation Intelligence, Deals, Rhythm, Analytics, Clari Forecast and Inspect
- Existing customers — unchanged — the company said the Clari merger did not change existing contracts, pricing or renewal dates
Established sales teams, especially on Salesforce, that want disciplined cadences with call and pipeline insight.
Small teams that want published prices, a built-in contact database or features such as inbox rotation for high-volume cold email.
How it scored
- AI outreach & personalization: 80/100. Cadences and AI-prioritized next steps help reps run structured outreach, though users say the AI sometimes lacks account context.
- Lead data & deliverability: 70/100. It handles email and calling well inside cadences, but it has no contact database and users note missing domain rotation.
- Value: 60/100. Prices are not published and the platform is aimed at larger teams, so cost is hard to judge before a sales call.
- Privacy & reliability: 60/100. It holds SOC 2 Type 2, ISO 27001 and ISO 27701 certifications and lets admins limit AI features, but its Salesforce integrations were switched off for about ten days in 2025 and some users saw multi-day CRM sync delays in September 2026.
- Expert & User Ratings: 80/100. Reviewers place it among the main sales engagement platforms and a very large number of users rate it highly.
Our verdict
Salesloft ranks tenth: users rate its cadences, AI-prioritized next steps and Salesforce connection highly for structured sales teams. It has no contact database, prices are not published, and CRM sync was interrupted for days at a time in 2025 and 2026.
- Cadences that users say make follow-ups easier to organize
- AI prioritization of next steps through Rhythm
- Strong Salesforce integration, with call insights and forecasting in the same platform
- Pricing is not published
- Users report missing cold-email features such as domain rotation
- Users report integration issues, and CRM sync has been interrupted for days at a time in 2025 and 2026
- Pricing comes only from a sales quote; plan names and seat terms are not public.
- After the Clari merger the company said there were no planned forced migrations and that existing contracts were unaffected.
- There is no built-in B2B contact database, so lead data comes from a separate provider.
- Outage: From August 28 to September 7, 2025, Salesloft’s Salesforce integrations were switched off, pausing CRM sync for customers for about ten days; in September 2026 some users also saw CRM sync delays lasting several days.

How to Choose
Start with your biggest bottleneck
If you lack good leads, look first at tools with a strong contact database and enrichment; if you have leads but struggle to write and follow up, a sequencing tool with good AI writing matters more. Teams that want to hand off whole steps can look at AI agents, but most still need a person reviewing what goes out.
Test the contact data before you commit
Contact accuracy is the most common frustration users raise, and outdated emails lead to bounces that harm your sending reputation. Use a trial to pull a list in your own market and check how many emails and phone numbers are actually right.
Protect your deliverability
Cold email only works if it reaches the inbox. Look for warm-up, sending limits, inbox rotation and email verification, and plan to send from separate domains and mailboxes rather than your main company address.
Work out the real monthly cost
Plans are priced per user, per mailbox, per contact or by credits, and data lookups, AI agents, LinkedIn steps and dialers are often extra. Add up seats, credits and add-ons for the volume you plan to send, and check whether the best price requires an annual contract.
Check how it fits your CRM and channels
Make sure it syncs reliably with the CRM you use and covers the channels your buyers respond to, whether that is email, LinkedIn, phone or text. A tool that fights your existing process will cost more time than it saves.
Keep a person reviewing the AI
AI-written messages can sound generic or get details wrong at volume, which can hurt your brand and your domain. Start with small batches, review drafts before they send and read how each tool uses the data and emails you give it.
Frequently Asked Questions
What does an AI sales assistant do?
It helps with the repetitive parts of outbound selling: finding and researching prospects, writing personalized emails and LinkedIn messages, scheduling follow-up sequences and sorting replies. Some tools add an AI agent that can run these steps on its own, while others act more like a writing and research helper for your reps.
Can an AI SDR replace a human sales rep?
Not fully, according to most reviewers. AI agents can research leads, send first-touch messages and answer simple replies at volume, but users often report generic messages and need to review and tune them. Most teams get better results using these tools to give reps more time rather than to replace them.
Do I need a separate email domain for cold outreach?
It is strongly advised. Sending cold email from your main company domain can damage its reputation if messages are marked as spam. Most outreach tools expect you to set up secondary domains and mailboxes, warm them up and keep daily sending low.
Do these tools use my emails and data to train AI?
It varies. Some vendors say they use usage data to improve their own models, while others say customer content is not used for training or name the AI providers that process it. If this matters to you, read each tool’s AI and privacy terms and ask for a data processing agreement.
How are these different from email marketing tools?
Email marketing tools send newsletters and campaigns to people who signed up to hear from you. Sales outreach tools send one-to-one style messages to prospects you have researched, with follow-ups and reply handling, so we rank email marketing tools on a separate page.
