What Overloop does
Overloop combines a database of over 450 million verified B2B contacts with AI-driven campaign automation. You define your ideal customer profile, and the platform builds prospect lists, writes outreach messages, and sequences follow-ups across email and LinkedIn — without manual list-building or template-filling.
The AI drafts each email by analysing a prospect's website and social profiles, then writes in your tone rather than pulling from a generic template. Campaigns track opens, clicks, replies, and bounces so you can see what is and isn't working and adjust over time.
Overloop sits inside a broader sales workflow: it connects to Salesforce, HubSpot, Pipedrive, Gmail, and Slack, and includes built-in email verification to protect deliverability. The vendor states it is GDPR-compliant and holds CASA Tier 2 certification for handling sensitive data.
Key capabilities
450M-Contact B2B Database
Filter by location, company size, industry, and job title to build targeted prospect lists. Each contact sourced or email found costs one credit from your monthly allowance.
AI-Written Personalised Emails
The platform researches each prospect's website and social profiles and writes individual emails in your voice. No shared templates or variable placeholders.
LinkedIn Outreach Automation
Automates LinkedIn connection requests and follow-ups as part of a multichannel sequence. Vendor states the approach is designed to avoid account risk and is GDPR-compliant.
Email Verification and Deliverability
Real-time bulk email verification reduces bounce rates before messages are sent. The platform includes a deliverability algorithm shaped by the vendor's campaign history.
Campaign Performance Tracking
Dashboards show opens, clicks, replies, bounces, and out-of-office responses at the campaign level so you can refine targeting, messaging, and timing.
CRM and Tool Integrations
Native connections to HubSpot and Pipedrive are available on the Growth plan; Salesforce integration is Enterprise-only. Gmail, Slack, and Zapier are included from the Starter plan.
Best for
- Small to mid-size sales teams running outbound prospecting who want to reduce time spent on list-building and manual email writing
- Founders or individual contributors doing their own outreach across both email and LinkedIn and needing a single platform to manage both channels
- Agencies running lead generation or outreach campaigns on behalf of multiple clients, given the agency use case is explicitly supported
- Teams that need a built-in contact database rather than purchasing one separately, and can work within a monthly credit model
- Businesses that need GDPR-compliant outbound tooling, particularly those operating in or selling into European markets
Worth knowing
- Pricing is credit-gated: every contact sourced from the database and every email address found costs one credit. Starter users get 250 credits per month; Growth users get 500. Heavy prospecting volumes may exhaust credits quickly.
- Salesforce integration is only available on the Enterprise plan, which has custom pricing. Teams dependent on Salesforce will need to budget for that tier.
- The platform is built specifically for outbound prospecting; it is not a full CRM. If your primary need is pipeline management, deal tracking, or inbound lead handling, you would need a separate tool.
- Implementation is estimated at one to two weeks, and Starter and Growth plans use self-onboarding with chat support only. Hands-on technical setup and a dedicated success manager are reserved for Enterprise.
- If your outreach volume is low or your sales motion is primarily inbound or relationship-led, the per-user monthly cost may not be justified against the value delivered.
How Overloop compares
Database-plus-outreach tools look alike on paper. The differences are channel range, how data is charged for, and which CRM connections come on which plan. Overloop keeps to email and LinkedIn, with AI-written emails and credit-gated data.
vs lemlist
lemlist also pairs a large lead database with outreach, but sequences across more channels — email, LinkedIn, calls, SMS and WhatsApp — with intent agents and a deliverability hub, from $55 per user (annual). Overloop focuses on email and LinkedIn, with AI-written emails in your voice, from $69. Choose lemlist if you need more channels; Overloop if email and LinkedIn cover your outreach.
vs Apollo.io
Apollo.io combines its contact database with sequencing, inbound lead routing and deal support, at $49–$119 per user, and connects to Salesforce and HubSpot. Overloop stays on outbound prospecting and positions itself on GDPR compliance, with Salesforce reserved for Enterprise. Choose Apollo.io if you need inbound routing or Salesforce on a standard plan; Overloop for outbound into GDPR-sensitive markets.
vs Reply.io
Reply.io adds calls, SMS and WhatsApp to email and LinkedIn, builds deliverability infrastructure in and offers the Jason AI SDR from $500 a month, with plans from $49. Overloop is simpler, with self-onboarding on its lower plans and data bundled into credits. Choose Reply.io for a full sending operation; Overloop for AI-written email and LinkedIn campaigns from one database.
