Vatsal Shah ZeroBounce is known for its email verification capabilities.
But it also does email warmup and inbox placement testing.
ZeroBounce ONE costs $99/month and bundles email verification, warmup, and inbox placement testing into one plan.
Sounds convenient, right?
But here’s the catch: you’re paying for 5,000 verification credits, warmup for only 2 accounts, and 100 placement tests.
If you need to scale beyond 2 inboxes or run more frequent tests, ZeroBounce’s pricing doesn’t make sense.
I tested 20 tools across all three categories over 4 weeks
I verified 50,000+ emails, warmed up 20 inboxes, and ran 200+ inbox placement tests to see which alternatives deliver better results at lower prices.
In this guide, you’ll find 8 ZeroBounce alternatives organized by what you actually need:
- Email Verification only
- Email Warmup only
- Inbox Placement testing only
- Or all-in-one platforms.
Some save you money. Some give you unlimited features ZeroBounce caps.
And one all-in-one alternative matches ZeroBounce’s price but delivers significantly better value.
Let’s dive in.

ZeroBounce Competitors That I Tested but Didn’t Meet the Cut
I tested 6 additional tools that didn’t make the final list. Here’s why they didn’t qualify:
Verification tools excluded:
- Snov.io – Poor accuracy on enterprise emails. Independent benchmarks showed it misclassified up to 75% of valid enterprise addresses. Not reliable enough for B2B teams.
- BriteVerify – Expensive for the features offered. Lacks advanced data insights compared to Clearout or NeverBounce.
Warmup tools excluded:
- Lemwarm – Too expensive at scale. Per-inbox pricing becomes prohibitive for teams warming 5+ accounts.
- Mailwarm – Limited ESP support. Doesn’t work with all major email providers.
All-in-one tools excluded:
- Hunter.io – Great for prospecting and verification but no warmup feature. Not a true ZeroBounce alternative.
- Mailfloss – Automated verification with ESP integrations but no warmup or placement testing.
The bottom line: These 6 tools either cost too much, lacked critical features (warmup or testing), or had accuracy/performance issues that disqualified them.
Choose the Best Alternative to ZeroBounce
You’ve seen 8 alternatives.
Here’s how to pick the right one based on your needs.
- For verification only: → Clearout ($21/3K emails) – 65% cheaper than ZeroBounce
- For warmup only: → TrulyInbox ($79/month unlimited) – Best for 3+ inboxes
- For testing only: → Inbox Radar ($49/month, 120 tests) – 58% cheaper per test with professional B2B seed list

If you need all three features at ZeroBounce’s price point, Saleshandy Outreach Pro delivers the best value with unlimited warmup.
If you primarily need warmup and sequences, Instantly.ai Growth saves you $52/month.
