Salesloft has 3,900+ G2 reviews at 4.5 out of 5, and for teams focused on rep adoption and ease of sequence building, the rating is fair. The problem is ownership. Clari's acquisition of Salesloft in January 2024 shifted its product roadmap toward revenue execution platform consolidation rather than pure engagement feature development. For teams evaluating a fresh engagement platform purchase, or for existing Salesloft customers considering alternatives, this matters.
The five alternatives below cover the main options: a direct competitor for mid-market and enterprise teams, a conversation intelligence platform with engagement sequences bundled in, a data-driven API-first engagement tool, a high-volume outbound option for SDRs, and a CRM-native integration for teams already in HubSpot or Salesforce.
| Tool | G2 Rating | Starting Price | Best For |
|---|---|---|---|
| Outreach | 4.3 (3,400+ reviews) | Quote only (~$45K/year for 10-15 reps) | Ops-driven teams, complex sequences, A/B testing |
| Gong (with Sequences) | 4.7 (5,800+ reviews) | Quote only (~$1,200-$1,600 per user/year) | Enterprise teams that want deal intelligence + engagement |
| Apollo.io | 4.4 (1,600+ reviews) | $49/user/month (Starter); includes prospecting data | Growth-stage teams, ICP-focused outbound, all-in-one tools |
| Instantly | 4.2 (380+ reviews) | $29/month (flat); per-user pricing from $99/month | SDR teams, high-volume outbound, budget-conscious teams |
| Mixmax | 4.5 (1,100+ reviews) | $49/user/month (Plus plan); email-first approach | Teams that live in Gmail or Outlook, email-centric workflows |
Outreach: the direct Salesloft competitor
Outreach is the closest feature parity alternative to Salesloft. Both platforms occupy the mid-market and enterprise sales engagement space, both emphasize sequence automation and multi-touch outreach, and both require revenue ops investment to extract full value. The main differences are workflow philosophy and pricing model.
Outreach favors complexity. Its sequence builder supports up to 12 A/B test variants per step, deep conditional logic with multiple branching paths, and integration-driven actions that can trigger workflows in connected systems based on prospect response. This power appeals to ops teams building multi-touch sequences that respond to buyer behavior in real time. G2 reviewers describe Outreach as more "configurable but steeper onboarding" compared to Salesloft's "simpler, faster to stand up."
Pricing data from Vendr puts typical Outreach contracts in the $40K-$50K annual range for a 10-15 rep team, roughly comparable to Salesloft's post-Clari pricing. Both require custom negotiation; neither publishes standard per-seat rates. The operational cost of maintaining complex sequences is higher on Outreach, so teams need stronger RevOps resources to realize the value. Without that, Outreach can sit idle while Salesloft's simpler templates get executed.
Choose Outreach over Salesloft if: Your primary use case is complex, conditional multi-touch sequences with heavy A/B testing, you have a dedicated revenue operations resource, or you want more engagement flexibility than Salesloft's acquisition-driven roadmap now provides.

Gong (with Sequences): conversation intelligence plus engagement bundled
Gong's primary reputation is conversation intelligence and deal analytics, but since acquiring Salesloft in January 2024, Gong now offers embedded sequences and engagement automation as part of its platform. For teams already using Gong for call recording and deal intelligence, adding engagement sequences keeps data in one place: reps' activity histories, conversation data, and sequence execution all surface in the same system rather than requiring data sync between Salesloft and a separate tool.
The sequences feature in Gong is simpler than Salesloft's or Outreach's. Gong optimizes for teams that want basic multi-touch templates (email, task, call reminders) without deep conditional logic or heavy A/B testing. The real value is consolidation: deal health signals from conversations flow into the engagement layer, and engagement activity flows back into deal scoring. For a 20-person team, paying Gong's enterprise rates ($1,200-$1,600 per user per year) for combined conversation intelligence and sequences is cheaper than buying both Gong and Salesloft separately.
The tradeoff is that Gong's engagement features lack the depth that teams choosing Salesloft or Outreach purely for engagement would expect. If your primary need is sales sequences with minimal call recording, Gong is over-scoped and over-priced. If your primary need is deal intelligence and you also want engagement sequences to activate deals, Gong makes sense.
Choose Gong (with Sequences) over Salesloft if: You're already a Gong customer and want to reduce tool sprawl, or your primary use case is deal intelligence but you also need engagement automation to activate insights.
Apollo.io: engagement plus prospecting data in one
Apollo.io is an all-in-one prospecting and engagement platform. It includes built-in B2B contact data (100M+ verified email addresses, phone numbers, and company information), sequence automation, email deliverability monitoring, and CRM sync. All are included in one system. At $49 per user per month, a 10-rep team costs roughly $6,000 per year, a fraction of Salesloft's enterprise pricing.
The engagement sequences feature in Apollo is more basic than Salesloft's. It covers standard multi-touch templates (email, task, call reminders) without the deep A/B testing or conditional logic that Outreach offers. Where Apollo's value emerges is in teams that currently pay for both Salesloft (for sequences) and a data provider (ZoomInfo, Clearbit, or Hunter) separately. Apollo collapses that into one tool, which simplifies operations and reduces cost.
Apollo's ICP targeting is its strongest angle. The platform lets you define a prospect profile, and Apollo surfaces matching prospects from its database with built-in email sequences ready to deploy. For growth-stage teams building pipeline through ICP-focused outbound rather than account-based execution, this workflow is faster than Salesloft plus a separate data provider.
Choose Apollo.io over Salesloft if: You currently bundle Salesloft with a third-party data provider, you have fewer than 15 reps, or your primary workflow is ICP-based prospecting rather than account-based or customer success engagement.
Instantly: high-volume SDR-focused outbound
Instantly is optimized for teams running high-volume outbound campaigns at scale. It emphasizes email deliverability, warm-up features to ensure emails land in inbox rather than spam, and ease of campaign management for SDR teams. Its pricing is either flat ($29/month for a single user) or per-user ($99+/month), making it accessible for smaller teams or companies bootstrapping sales.
Instantly's sequence builder is simpler than Salesloft's. It's designed for SDRs launching campaigns rather than for revenue ops teams building conditional multi-step workflows. Where Instantly excels is in managing deliverability and inbox placement. It includes warm-up flows, bounce handling, and domain reputation monitoring that Salesloft requires third-party tools to accomplish. For teams running high-volume campaigns where inbox placement directly affects ROI, Instantly handles that problem natively.
The tradeoff is integration depth. Salesloft's CRM sync and third-party integrations are more mature; Instantly's are growing but not as comprehensive. Teams evaluating Instantly need to assess whether their CRM and secondary tool stack integrates with Instantly's API, or whether they're willing to do manual data transfer.
Choose Instantly over Salesloft if: Your team runs high-volume SDR outbound with emphasis on inbox placement and deliverability, you have fewer than 10 reps, or you need a flat-rate pricing option rather than per-seat.
Mixmax: email-first engagement for Outlook and Gmail teams
Mixmax is a Chrome extension and Outlook add-in that turns Gmail and Outlook into a lightweight engagement platform. Sequences, templates, email tracking, and task management live inside your email client rather than in a separate tab. For teams that live in Gmail or Outlook and want engagement automation without leaving email, Mixmax is purpose-built.
Mixmax's strength is ease of adoption. There's no new interface to learn, no CRM data migration, no ops setup. A rep receives Mixmax on day one, starts using templates and tracking from Gmail, and the workflow is frictionless. G2 reviews consistently cite "fast implementation, minimal training" as Mixmax's differentiator versus Salesloft or Outreach.
Mixmax's sequences are functional but simpler than Salesloft's. The platform covers basic multi-touch workflows; it doesn't support the deep conditional logic or A/B testing that larger teams might need. For a 5-person SDR team building outbound funnels, Mixmax's simplicity is an advantage. For a 30-person organization with RevOps, it's likely under-featured.
Choose Mixmax over Salesloft if: Your team is small (under 15 reps), you want minimal implementation effort, or your primary engagement channel is email and you need tracking and templating without leaving Gmail or Outlook.
Which alternative fits your team
The choice depends on team size, engagement complexity, and what you're currently buying alongside Salesloft. If you run complex multi-touch sequences with heavy RevOps, choose Outreach. If you prioritize deal intelligence alongside engagement, Gong. If you currently buy both Salesloft and a data provider, Apollo consolidates those. If you're an SDR team optimizing for inbox placement, Instantly. If you live in Gmail and want minimal setup, Mixmax.
