The 7 best best sdr software tools, in detail

1

Outreach

Best for: Enterprise sequencing and AI

Outreach is the enterprise standard for sales development, and it suits large SDR and account executive teams that run complex sequences across email, calls, and LinkedIn. It covers sequencing, task management, conversation intelligence, forecasting, and AI agents that draft and prioritise outreach, all in one platform. That depth matters when a team runs hundreds of sequences, needs strict governance, and wants to see which steps, templates, and reps drive meetings.

Pricingquote only
Free plan / trialNo
  • Outreach also integrates with Salesforce and other CRMs, so activity logs to the CRM without manual work.
  • Pricing is quote only, with no public price list, no free plan, and no self-serve trial.
  • Third-party reports have cited about $100 per user per month for Amplify Core, about $130 for Plus, and about $160 for Pro, all annual, but those are
  • A platform fee and implementation cost have also been reported, which adds to the first-year cost.

Pros

  • Deep sequencing, AI agents, and analytics for large teams
  • Strong integrations with Salesforce and other CRMs

Cons

  • No public price and no self-serve trial
  • Annual contracts with a platform fee and implementation cost

Salesloft

Best for: Cadences and conversation intelligence

Salesloft is a revenue orchestration platform that covers cadences, email, calls, LinkedIn tasks, and conversation intelligence, and it suits revenue teams that want one workflow for SDRs and account executives. Cadences guide reps through each step, conversation intelligence records and analyses calls, and analytics show which cadences and templates book meetings. That combination helps a team that wants to standardise outreach, coach reps from real calls, and scale from ten reps to fifty without changing tools.

Pricingquote only
Free plan / trialNo
  • Salesloft also integrates with Salesforce and other CRMs, so activity and outcomes stay in sync.
  • Pricing is quote only, with no public price list, no free plan, and no free trial.
  • Third-party reports have cited about $125 to $165 per user per month for Advanced and Elite tiers, with negotiated prices near $100 to $130, but those
  • The dialer is a separate add-on, at about $300 to $400 per user per year, and it is not included in any tier.

Pros

  • Strong cadences, dialer, and conversation intelligence
  • Scales well for revenue teams with many reps

Cons

  • No public price and no free trial
  • Dialer is a separate add-on, not included in any tier

Apollo

Best for: Database plus sequences plus dialer

Apollo is the best all-in-one choice for small and mid-size SDR teams, because it combines a contact database, sequences, a dialer, and analytics in one self-serve product. A rep can find a contact, add them to a sequence, call them from the dialer, and track replies without switching tools or buying a separate database. That saves time and money for a team that cannot afford three separate tools, and it keeps data in one place.

Pricing$49 per user per month
Free plan / trialYes

  • The free plan costs $0, Basic costs $49 per user per month when billed annually, or $65 per month when billed monthly, Professional costs $79 per user
  • The credit model is the limit to check.
  • Credits expire each cycle, and a mobile number costs eight credits while an email costs one, so a team that calls mobile numbers will use credits fast
  • All seats on one account must be on the same plan, so a team cannot mix Basic and Professional seats.

Pros

  • Contact database, sequences, and dialer in one self-serve tool
  • Free plan to test the database and workflow

Cons

  • Credits expire each cycle
  • Mobile numbers cost more credits than emails

Reply

Best for: Multichannel outbound

Reply is a sales engagement platform for multichannel outbound, and it suits SDR teams that contact prospects by email, LinkedIn, calls, and SMS from one sequence. A rep can build a sequence that starts with an email, follows with a LinkedIn connection, and ends with a call, with tasks and replies tracked in one inbox. That multichannel view helps a team that sells to buyers who do not answer email alone, and it keeps the full outreach history in one place.

Pricing$49 per user per month

  • Reply also offers Jason AI SDR, an AI agent for automated outreach, from $500 per month when billed annually.
  • Pricing starts at $49 per user per month when billed annually for Email Volume, with 1,000 active contacts, or $59 per month when billed monthly.
  • Multichannel starts from $89 per user per month when billed annually, or $99 per month when billed monthly.
  • The Email Volume tier is email only: LinkedIn costs $69 per month per account, and calls and SMS cost $29 per month per account, as add-ons.

Pros

  • Multichannel sequences across email, LinkedIn, calls, and SMS
  • AI SDR option for automated outreach

Cons

  • Email Volume tier is email only
  • LinkedIn, calls, and SMS are separate add-ons

HubSpot Sales Hub

Best for: Sales tools inside HubSpot CRM

HubSpot Sales Hub is the sales product inside HubSpot CRM, and it suits teams that already use HubSpot for marketing or service and want sales tools in the same system. Contacts, deals, emails, and calls live in one CRM, so a rep does not need to sync data between tools, and a manager can see the full pipeline in one dashboard. The free plan costs $0 for up to two users, and Starter costs from $7 per seat per month when billed annually, as a new-customer discount, with a list price of $20 per seat per month.

Pricing$7 per seat per month

  • Professional costs $90 per seat per month when billed annually, or $100 per month when billed monthly, plus a $1,500 one-time onboarding fee, and Ente
  • The jump from Starter to Professional is the limit to plan for.
  • Sequences and automation are Professional or higher, so a team that needs sequences will pay $90 per seat per month, not $7, and Professional needs an
  • That jump is twelve times the Starter discount price, so check the feature list before you buy Starter.

Pros

  • Free plan for up to two users
  • Sales tools sit in the same CRM as marketing and service

Cons

  • Professional costs $90 per seat per month with onboarding

ZoomInfo Sales

Best for: Largest B2B contact database

ZoomInfo Sales is a B2B contact and intent database, and it suits enterprise teams that need the largest possible pool of contacts, with intent signals that show which accounts are researching a topic. A rep can search by company, role, technology, and intent, then export contacts to a sequence or CRM, which speeds up list building for a large team. The free Lite tier costs $0 and includes 10 credits per month, which gives a small team a way to test the data quality before buying.

Pricingquote only
Free plan / trialYes
  • ZoomInfo also covers company data, technographics, and org charts, which help a team that sells to large accounts.

  • Free Lite tier with 10 credits per month

Cons

  • Annual contracts only, with no public price

Smartlead

Best for: Flat-price cold email at scale

Smartlead is a cold email platform that charges a flat price per account, not per seat, which suits agencies and cold email teams with many mailboxes. Base costs $39 per month, or $32.50 per month when billed annually, Pro costs $94 per month, or $78.30 per month when billed annually, Unlimited Smart costs $174 per month, and Unlimited Prime costs $379 per month. That flat model means a team with ten mailboxes pays the same as a team with one mailbox on the same tier, which is a clear saving over per-seat tools.

Pricing$32.50 per month
Free plan / trialNo
  • Smartlead also includes email warm-up, inbox rotation, and deliverability tools, which help cold email reach the inbox instead of spam.
  • The Base tier has clear caps: 2,000 contacts and 6,000 sends per month, with API and CRM integrations only from Pro.
  • Client workspaces cost $29 per month each, and premium warm-up costs $59 per month below the $174 tier, so an agency should add those costs to the hea
  • There is no free plan, but a 14-day free trial is available with no card required.

Pros

  • Flat price per account, not per seat
  • Unlimited mailboxes and warm-up on higher tiers

Cons

How we chose

We chose seven tools that cover enterprise sequencing, all-in-one prospecting, multichannel outbound, CRM-native sales, and flat-price cold email. We checked the vendor pricing page for each tool on 2026-11-12, and we used quote only where the vendor publishes no list price. We favoured tools with a clear entry price or free plan, a published feature list, and current use by SDR teams. We did not claim hands-on testing, and we did not use review scores, awards, or customer counts as proof of quality. Where a price was only available from a third-party report, we said so in the text and did not present it as a vendor price.

Frequently asked questions

What is the best SDR software for a small team?

Apollo is the best choice for most small teams, because it combines a contact database, sequences, and a dialer in one self-serve tool, with a free plan and Basic at $49 per user per month when billed annually. Smartlead is the best choice for cold email only, at $32.50 per month when billed annually, with a flat price per account. HubSpot Sales Hub is the best choice for teams already on HubSpot, with a free plan for up to two users.

How much does Outreach cost?

Outreach publishes no price, so the starting price is quote only. Third-party reports have cited about $100 per user per month for Amplify Core, about $130 for Plus, and about $160 for Pro, all annual, but those are not vendor prices. A platform fee and implementation cost have also been reported. Ask Outreach for a written quote that names the tier, the seat count, the platform fee, and the implementation cost before you budget.

Is Apollo free?

Apollo offers a free plan at $0, with a contact database, sequences, and a dialer to test. Basic costs $49 per user per month when billed annually, or $65 per month when billed monthly, Professional costs $79 per user per month when billed annually, and Organization costs $119 per user per month, with a three-seat minimum. Credits expire each cycle, and mobile numbers cost eight credits while emails cost one, so check the credit use for your team.

Does HubSpot Sales Hub include sequences?

Sequences are available on Professional or higher, not on Starter or the free plan. Professional costs $90 per seat per month when billed annually, or $100 per month when billed monthly, plus a $1,500 one-time onboarding fee. Starter costs from $7 per seat per month when billed annually, as a new-customer discount, with a list price of $20. Check the feature list for the tier you need before you buy, because the jump from Starter to Professional is large.

What is the cheapest SDR software in this list?

Smartlead is the cheapest for a team, because Base costs $32.50 per month when billed annually, as a flat price per account, not per seat. HubSpot Sales Hub is the cheapest for a solo rep, with a free plan for up to two users. Apollo Basic at $49 per user per month is the cheapest all-in-one option with a database, sequences, and a dialer in one self-serve tool.

Do I need a contact database with SDR software?

It depends on the tool. Apollo and ZoomInfo include a contact database, while Salesloft includes no database, so a Salesloft team will need a separate data source. Reply includes only 50 live data credits per month on its entry tier, so a team that needs many new contacts will need more credits or another source. Check how many contacts you need each month, and whether the database, credits, and export limits are in the tier you would buy.
