Best Sales Engagement Platforms in 2026

Outreach, founded in 2014 and now operating from the outreach.ai domain, sells what it describes as an AI revenue workflow platform covering prospecting sequences, conversation intelligence, deal management and forecasting. Its four Amplify plans are all quote-based and priced on a combination of per-user seats and consumption-based AI credits: Essentials includes 10,000 AI credits, Core 25,000, Plus 50,000 and Pro 100,000.

Essentials covers AI agents for research and deals, AI call coaching and summaries, deal-health alerts, meeting scheduling, the Outreach Voice dialer and conversation analytics; Core adds multi-channel sequences, revenue and personalisation agents, engagement and attribution reporting and account planning; Plus adds meeting preparation, live coaching cards, data enrichment, relationship maps, deal management and the Outreach MCP server; Pro adds AI forecast projection, scenario planning, forecast roll-ups, territory management and multi-currency. Notably, multi-channel sequences, the core sales-engagement feature, begin at Core rather than Essentials. Outreach says sellers close more than two million opportunities a month on the platform. Extra AI credit packs, data sharing, connectors and listener licences are add-ons.

Salesloft's sales engagement product, Cadence, runs multi-step outreach, and the company now sells a broader platform that includes conversation intelligence, deal management, Rhythm (a prioritised workflow for sellers), Clari Forecast, pipeline inspection with Inspect, revenue cadences and analytics. Its site lists Clari Forecast as a platform product and provides login links to Clari Forecast, Conversations, Groove and Drift, indicating that these product lines are now sold together; the site itself does not set out the corporate terms.

Platform-wide capabilities include AI agents, MCP connectivity and a unified revenue data layer with continuous sync to Salesforce, Gmail and Snowflake. Named customers in testimonials include Wrike, Vention, Reachdesk and NetSupport. Salesloft publishes no plans or prices on its pricing page, which offers a tailored walkthrough with sales instead. For buyers, the combination of Salesloft's engagement product with Clari's forecasting tools creates a direct alternative to Outreach's engagement-plus-forecasting packaging.

HubSpot's Sales Hub combines CRM with sales engagement features, so sequences run on the same contact and deal records as the rest of the customer database. Sequences send timed, personalised email and task steps, can be enrolled from the HubSpot inbox or from Gmail and Outlook, adapt to engagement and support A/B testing and deal outcome reporting; branching sequences and advanced workflow logic are included from the Starter edition.

A free plan supports up to two users. Professional costs US$90 per seat per month with an annual commitment (the page also shows US$100), includes 3,000 HubSpot credits and carries a one-time US$1,500 onboarding fee; Enterprise costs US$150 per seat per month with 5,000 credits and a US$3,500 onboarding fee. The page also lists a Starter edition with 500 credits, though the two prices it displays are not clearly matched to billing options. Professional and Enterprise allow up to 5,000 sequences per account and up to 10,000 email templates, while Starter is limited to three templates and three snippets. LinkedIn steps in sequences require a separate Sales Navigator subscription.

Apollo.io combines a B2B contact database, which it lists at 240 million contacts and 30 million companies, with email sequencing, dialing and AI features, and says more than 600,000 companies use it. Customers named on its pricing page include Intel, AT&T, Adobe, SAP and Shopify. Email campaigns are included on every account, but free accounts can connect only Gmail; paid plans connect Microsoft and other providers.

Plans run from Free through Basic, for individual sellers doing regular outbound with sequencing and core integrations, and Professional, adding higher credit limits, AI features, call recording and advanced CRM integrations, to Custom, which adds SSO, advanced security, dedicated support and API access. Actions such as revealing emails and phone numbers, email warm-up, mailboxes and AI-researched data fields consume credits, which are pooled across the team, granted at the start of each billing cycle and expire if unused, including add-on credits. Annual billing is discounted but commits the buyer for 12 months, and all seats on an account must be on the same plan. The pricing page viewed for this list did not display dollar amounts, so none are given.

Amplemarket sells an all-in-one outbound platform covering contact data, multichannel sequences, deliverability tools, AI intent signals and AI assistants branded Duo, with an MCP integration. Its Startup plan costs US$600 per month on an annual term and includes two users, 27,000 contacts, multichannel sequences, intent signals, the Duo Copilot and a shared customer success manager. Growth, with four users and 140,000 contacts, adds Duo Voice and a dedicated success manager; Elite, with ten users and 400,000 contacts, adds Duo Inbox; both are custom-priced.

Annual per-user credit allowances rise from 13,500 email and 600 phone credits on Startup to 40,000 and 9,600 on Elite, with mailboxes per user starting at two, four and eight. All plans include a free trial, and additional users can be purchased on each plan, though per-user prices are not listed. The company positions itself as a replacement for combinations of Apollo, Outreach, ZoomInfo, Salesloft and Cognism, and cites a customer that reported cutting tooling costs by about 56% after consolidating, a vendor-published claim.

Klenty Soft Inc. sells a sales engagement and dialer suite. Its Starter plan is a flat US$50 per month billed annually, with unlimited users and mailboxes, 15,000 contacts and 75,000 emails a month, deliverability tools, A/B testing, templates, approval before sending and API access. Growth costs US$70 per user per month and adds cold-calling tools (number rotation, AI voicemail and IVR detection), a Rep360 coaching dashboard, SMS, social selling, a one-click dialer and a two-way CRM plugin, with 200 call minutes and 2,000 data credits.

Plus costs US$99 per user per month and adds account-based selling with an AI that schedules follow-ups, and call coaching with AI battlecards, live transcription, objection detection and scorecards, with 1,000 call minutes and 4,000 data credits. A power and parallel dialer is a US$45 per user per month add-on, and local-presence numbers covering 335 US area codes cost US$50 per seat per month. A 14-day trial includes up to 200 prospect emails. Klenty states SOC 2 Type II certification and integrates with Zoho, Pipedrive, HubSpot, Salesforce, Microsoft Dynamics and Gong.

lemlist, operated by lempire, combines a lead database of more than 650 million leads with multichannel outreach by email, LinkedIn, calls, SMS and WhatsApp, plus deliverability tools and AI agents. It says more than 20,000 sales teams use it, naming ElevenLabs, Pennylane and Spendesk among clients.

The Email plan costs US$55 per user per month on yearly billing (US$69 before discount) and includes unlimited users and senders, 50,000 emails a month, an email and phone finder, AI agents, MCP and CLI access, warm-up, a deliverability hub and CRM integrations. Multichannel costs US$87 per user per month yearly (US$109 list) and adds five senders per user, unlimited emails and messages, LinkedIn automation, SMS, a built-in dialer and use from Gmail and LinkedIn; Enterprise adds SSO, custom roles and a dedicated account manager. Quarterly billing saves 10% and yearly 20%. Credits for enrichment and buying signals are charged only for successful results and roll over while the subscription is active. A 14-day trial includes Multichannel features and 200 credits.

Mixmax, Inc. adds sales engagement features to Gmail: automated sequences to up to 15,000 recipients a month, unlimited email tracking, reminders, one-click scheduling, AI meeting notes, templates, polls, AI composition and Sidechat for teammates, plus CRM sync and reporting. Pricing is per user and tiered by monthly sequence recipients: free for 50 recipients with limited features, US$29 per month for 100 and US$89 regular price for 1,500, with a 3,000-recipient tier also offered; annual billing saves 15–25%.

Recipient allowances are per user, cannot be pooled and do not roll over, although contacts already in a sequence continue to receive follow-ups after a limit is hit. Add-ons at US$9 per member per month on annual billing (US$12 monthly) include custom branding, advanced workspace rules, a Salesforce Insights package and a dialer with per-minute charges. A 14-day trial at the 1,500-recipient tier requires no credit card. Mixmax states SOC 2 Type II and SOC 3 reports, GDPR and CPRA compliance, and HIPAA business associate agreements.

Yesware is a sales email and engagement product that works inside Gmail and Outlook and says more than 6,000 teams use it; its pricing page logo reads "Vendasta-Yesware", although the page does not explain the relationship. Plans are priced per seat: Free; Pro at US$15 per month annually or US$19 monthly, with unlimited open, link and attachment tracking and 20 campaign recipients a month; Premium at US$35 annually or US$45 monthly, removing branding and adding unlimited campaigns, shared templates and team reporting; and Enterprise at US$65 annually or US$85 monthly, adding a Salesforce inbox sidebar, activity sync, list-view import and Salesforce SSO.

A Prospector add-on draws on a database of more than 100 million B2B contacts, though the credit prices shown on the page are inconsistent. Yesware offers to buy out customers from unwanted competitor contracts by crediting the remaining value against annual billing. It states SOC 2 Type II and GDPR compliance and integrates with Salesforce, LinkedIn, Zoom, Microsoft Teams, DocSend, Clari and RingCentral. Compared with Outreach or Salesloft, it is lighter, focused on email rather than calling or forecasting.

Instantly.ai is a cold email platform whose plans include unlimited email accounts and warm-up, a feature that suits teams rotating sending across many mailboxes. It also sells a B2B lead database of more than 450 million leads, email verification, a CRM and AI agents, and says more than 50,000 sales teams use it. Bundles combining outreach, credits and leads cost US$94 per month for Starter (5,000 emails and 1,000 contacts), US$194 for Scale (100,000 emails and 25,000 contacts) and US$555 for Agency (500,000 emails), with yearly billing about 10% lower.

Outreach-only plans start with Growth at US$47 per month for 5,000 emails and 1,000 contacts; the page shows conflicting prices for higher outreach tiers, so they are not repeated here. Scale adds an AI reply agent, a unified inbox and advanced deliverability features. A managed VIP service sets up domains, accounts and campaigns for a custom fee. Instantly lacks the calling, coaching and forecasting functions of enterprise platforms; it is built for email volume.

Smartlead is a cold email outreach platform with a master inbox and built-in warm-up, and says it is used by more than 100,000 businesses. All plans include unlimited email accounts, and sending rotates automatically across connected mailboxes. Base costs US$39 per month (US$32 annually) for 2,000 contacts and 6,000 emails; Pro costs US$94 (US$78) for 30,000 contacts and 90,000 emails; Unlimited Smart costs US$174 (US$144) with unlimited contacts and 150,000 emails; and Unlimited Prime costs US$379 (US$315) for 500,000 emails, including three dedicated sending servers and three client workspaces.

White-labelling costs US$29 per client workspace per month from Pro onward, which makes Smartlead popular with agencies. Add-ons include mailboxes from about US$4.20 to US$9 each per month, domains, deliverability testing from US$49 per month, dedicated servers at US$39 each, verification credits and a voice dialer billed in credits. A free trial needs no credit card, and there are no lock-in contracts. The pricing page contains some conflicting price blocks; figures here follow the plan structured data.

Mailshake sells cold email and sales engagement software priced per user, with each user connecting one mail account. Starter costs US$29 per month (US$25 yearly) with one email address and 1,500 sends a month; Email Outreach costs US$49 (US$45) with two addresses and unlimited sends, adding email rotation, a unified inbox, Salesforce, Pipedrive and HubSpot integrations and a browser extension; Sales Engagement costs US$99 (US$85) with ten addresses and adds five phone numbers, a power dialer with unlimited free minutes to North American numbers, phone scripts and account-level views. An Agency plan is quoted.

Unlike most competitors here, Mailshake offers no free trial and collects payment upfront, relying instead on concierge onboarding and deliverability training. It says more than 100,000 sales teams have used it.
