Snov.io earns a 4.5–4.6/5 on G2 by doing something most tools don't: unlimited team seats on all paid plans. For startups and growing teams, this is a genuine economic advantage, no linear cost growth as headcount increases. Add in built-in email finding, warmup, drip campaigns, and a lightweight CRM, and Snov.io offers a more complete stack at lower all-in cost than stitching Apollo + Instantly + HubSpot.
But the #1 G2 complaint is consistent and meaningful: open and click tracking inconsistency. Users report that reported open rates and click rates don't match reality, sequences show activity that can't be verified, or fail to report genuine engagement. For teams making sequence optimization decisions based on these metrics, this is a fundamental reliability issue. Credit burn confusion and data gaps for non-English markets round out the primary pain points.
