Snov.io
All-in-one sales prospecting platform combining email finding, verification, drip campaign automation, and CRM features to support the full outbound sales workflow from lead discovery to outreach.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
TLS enforced. OAuth 2.0 client credentials is marginally stronger than plain API key but provides no scope granularity — tokens have full account access. Client secret must be stored securely by the integrating application. No audit logs or token management controls via API. GDPR data processing agreement available. Email data for found contacts raises additional GDPR considerations for EU-based targets.
⚡ Reliability
Best When
A sales or growth team needs to build prospect lists from scratch, verify email accuracy, and immediately run outreach campaigns — all in a single integrated workflow.
Avoid When
You already have clean verified contact lists and only need a sequence/outreach tool, or you need enterprise-grade multi-channel engagement.
Use Cases
- • Finding and verifying email addresses for prospects from domain names or LinkedIn profiles
- • Running drip email campaigns with automated follow-up sequences to discovered leads
- • Verifying email lists in bulk before outreach to reduce bounce rates and protect sender reputation
- • Enriching contact data by finding emails associated with company domains at scale
- • Building prospecting pipelines that combine email discovery, verification, and outreach in one tool
Not For
- • Enterprise sales teams needing advanced multi-channel sequences (email + phone + LinkedIn) — Outreach or Reply.io are better suited
- • Teams with existing verified contact lists who only need outreach tooling
- • High-volume transactional or marketing email delivery
- • Organizations requiring HIPAA compliance or sensitive data handling guarantees
Interface
Authentication
OAuth 2.0 client credentials flow — client ID and client secret are exchanged for an access token. Tokens have limited lifetime and must be refreshed. No granular scopes — all tokens have full account access. Client credentials obtained from the Snov.io API settings page.
Pricing
Credit-based pricing for email finding and verification. Email campaign sending is based on recipient limits. Credits and recipients refresh monthly. Free tier suitable for testing but limited for production use.
Agent Metadata
Known Gotchas
- ⚠ OAuth client credentials flow requires token refresh — agents must implement refresh logic as tokens expire; not documented with clear expiry times
- ⚠ Email finding operations consume credits even for invalid or unverifiable emails — agents with retry logic can exhaust credit budget quickly
- ⚠ Email verification results include confidence scores but no clear threshold is documented for safe-to-send determination
- ⚠ No webhooks available — agents must poll campaign status endpoints to check progress
- ⚠ Prospect list operations (add, remove) are asynchronous — status must be polled rather than read from response
- ⚠ GDPR unsubscribe handling removes contacts from Snov.io lists but agents must propagate this to other systems manually
- ⚠ API rate limits are not clearly documented; hitting limits returns 429 without clear Retry-After headers on all endpoints
- ⚠ Credit balance depletion silently fails email find operations rather than returning a billing error on some endpoints
