Overloop

1. 1

   You describe your ideal customer profile and Overloop's AI engine drafts the campaign: sourcing criteria, channel mix (email-only, LinkedIn-only, or both), step timing, and the messages themselves, written from context about you and the prospect rather than a mail-merge template. Everything is editable before launch, and each sequence supports configurable follow-up triggers based on prospect behavior.

2. 2

   Prospect sourcing runs against Overloop's 450M-contact B2B database on a credit meter: one credit to source a prospect, one credit to find and verify an email address. Credits are included per user per month by tier (250 on Starter, 500 on Growth, 1,000 on Enterprise) and deducted in real time; imported lists can be verified through the same engine.

3. 3

   Outreach then executes across connected mailboxes with built-in warm-up routing low-volume traffic through third-party networks and sending paced below provider limits. LinkedIn steps are deliberately measured, with platform limits surfaced and a human-review checkpoint so automated social touches stay within LinkedIn's tolerances.

4. 4

   Replies, out-of-office bounces, and engagement data flow into campaign analytics, and conversations sync to HubSpot or Pipedrive on Growth and to Salesforce on Enterprise. Slack, Calendly, Zapier, a Chrome extension, and a REST API (Growth and up) round out the workflow surface.

Per-user monthly subscription in three tiers, differentiated by included sourcing credits, connected email accounts, concurrent campaigns, and CRM integrations; prospect sourcing and email finding are metered in credits (1 credit each).

Value assessment: Judged as one subscription replacing three (a data tool, an AI copywriter, and a sender with warm-up), $69 to $99 per user is fair and simple, and for founders and small teams the consolidation is the whole point. Judged as a sending platform alone it is expensive: pure-play senders undercut it badly, and 250 Starter credits (roughly 125 fully sourced-and-verified contacts a month) run out fast for anyone doing real volume. The economics work when you use all three layers; teams that already own good data should not pay Overloop's bundle premium.

Setup time

Under a day: connect a mailbox, describe an ICP, review the AI-drafted campaign. Add 2 to 4 weeks of warm-up before real volume on fresh mailboxes, per category norms.

Learning curve

Low. The AI does the campaign scaffolding, and the review-then-launch loop is simpler than assembling sequences by hand. Credit budgeting and LinkedIn pacing settings are the only concepts requiring attention.

Onboarding

Self-onboarding with chat support on Starter and Growth; Enterprise adds personalized 1:1 onboarding and a dedicated CSM.

Migration notes

Prospect lists import via CSV or Chrome extension; campaigns must be rebuilt (or regenerated by the AI, which lowers the cost of starting over). No import of historical campaign metrics from other platforms. Existing customers kept product, pricing, and logins unchanged through the Sortlist acquisition.

Platforms

Web appChrome extensionREST API (Growth and Enterprise)

API

REST API on Growth and Enterprise for prospect, campaign, and reply management; Zapier covers lighter automation on all tiers.

Data residency

EU-hosted; the company confirmed continued EU hosting and independent operation under its Belgian entity after the Sortlist acquisition.

SSO

No published SAML SSO offering.

Security notes

Mailbox connections use standard OAuth; no SOC 2 report is publicly referenced as of this review. The vendor operates under a Belgian entity with GDPR obligations applying to its prospect database.

Overloop is the most coherent AI SDR pitch in the SMB tier: one subscription that finds the people, writes the outreach in your voice, keeps a human in the loop, and handles deliverability plumbing. For founders and small teams starting from no list, that consolidation genuinely beats assembling Apollo-plus-copywriter-plus-sender. The caveats are the mirror of the strengths: tight credit math at $69, Salesforce held hostage by Enterprise pricing, a deliberately shallow LinkedIn layer, and a small team now owned by an agency marketplace with its own agenda. Buy it as a bundled starting engine for precise outbound; skip it if you already own good data or need volume, phone, or enterprise controls.
