Hunter vs Right Inbox: They're Not Even Competitors
You're comparing a fishing boat to a bicycle. Hunter finds emails, verifies them, and runs cold outreach campaigns. Right Inbox adds scheduling, reminders, and tracking inside Gmail. The overlap between these two tools is razor-thin.
We've tested both, and they only share a couple of features - sequences and tracking. Even then, Hunter's Gmail tracking lives in a separate product called MailTracker, which muddies the comparison further.
30-Second Verdict
- Hunter: You need to find and email prospects you've never contacted. Email finder, verifier, cold sequences, API - it's an outbound sales tool.
- Right Inbox: You need Gmail superpowers - scheduling, reminders, tracking, recurring emails. It's a productivity layer, not a prospecting platform.
- Skip both if: Your real bottleneck is verified contact data at scale. Neither tool fixes a bad-data problem. (If that's you, start with data enrichment and verification.)
What Each Tool Actually Does
Hunter
Hunter's core job is finding professional email addresses and running cold outreach. Domain Search pulls every known email at a company. Email Finder gets a specific person's address. The built-in verifier checks deliverability before you hit send, and Sequences handles multi-step cold campaigns with follow-ups and reporting. There's also Signals for intent data and an API for bulk workflows.
The credit-based model starts with 50 free credits per month. Paid plans run from $34/mo (Starter, 2,000 credits) up to $209/mo (Scale, 25,000 credits) on annual billing, with Growth at $104/mo for 10,000 credits. Every plan includes unlimited users - you pay for credits, not seats. In our experience, that model scales far better than per-user pricing once you're past three reps.
Right Inbox
Right Inbox bolts onto Gmail and stacks on features: Send Later, Reminders, Recurring Emails, Mail Merge, Sequences, Templates, CRM Sync, Inbox Pause, Email Encryption, Email Summarizer, and open/click tracking. Over 250,000 professionals use it, with 12,000+ Chrome Web Store reviews and a 4.8/5 on G2. That said, all 22 G2 reviews are 5-star, so take that sample size with a grain of salt.
It's Gmail only. No Outlook support, and compared to shared inbox tools, it's light on admin and collaboration controls. If your org has strict security requirements, it's worth reviewing the OAuth scopes and your extension policy before installing.
Hunter's 50 free credits run out fast, and Right Inbox can't find a single email. Prospeo gives you 75 free verified emails per month from 300M+ profiles at 98% accuracy - with 5-step verification, catch-all handling, and spam-trap removal baked in.
Fix your data before you pick a sending tool.
The MailTracker Bridge
Here's the thing most comparison articles miss: Hunter owns MailTracker, a standalone Gmail tracking extension that's the actual apples-to-apples competitor to Right Inbox's tracking feature. MailTracker's free plan gives you 20 tracked emails per month vs. Right Inbox's 5. No watermark, no branding on your emails, and it doesn't require permission to read or manage your Gmail messages.
If you're evaluating tracking specifically, it helps to understand how an email tracking pixel works (and where it breaks).
One caveat: Apple Mail Privacy Protection pre-loads tracking pixels, which inflates open rates across every tracking tool. Prioritize click and reply tracking over opens regardless of which one you pick.
Paid MailTracker plans run $20/month for unlimited tracking. It holds a 4.7/5 across 4,900+ Chrome Web Store ratings.

Right Inbox's Professional plan charges per user. The Team plan runs $16.95/month billed yearly and includes unlimited team members - a distinction that matters once your team grows past a handful of reps. Hunter includes unlimited users on every plan.
Which One Do You Actually Need?
You need to find and email prospects you've never contacted. Use Hunter. Right Inbox can't find a single email address for you. If you're shopping around, compare options in our Hunter alternatives guide.
You need to schedule, track, and manage emails in Gmail. Right Inbox covers the full suite, or MailTracker works if you only care about tracking. Fair warning: G2 reviewers flag send-later bugs, emails stuck in drafts, and subscription management friction. Boomerang for Gmail is the stronger alternative if those issues concern you.
You need verified B2B contact data before any outreach tool matters. This is where Prospeo fits. Hunter's credit model gets expensive at volume - 50 free credits vs. Prospeo's 75 free verified emails per month with 98% accuracy across 300M+ profiles. Right Inbox doesn't touch prospecting at all. If your emails bounce, the problem isn't your tracking tool - it's your data. Prospeo's 5-step verification with catch-all handling and spam-trap removal keeps bounce rates under 4% for teams like Meritt, who tripled pipeline from $100K to $300K/week after switching.
If you're diagnosing deliverability, start with email bounce rate benchmarks and an email deliverability guide before you change tools.
Let's be honest: most teams searching for this comparison don't need either tool yet. If your bounce rate is above 5%, no amount of scheduling or sequencing fixes the problem. Fix the data first, then pick your sending stack. (If you need help with messaging after that, use these sales follow-up templates.)
Teams like Meritt cut bounce rates from 35% to under 4% and tripled pipeline to $300K/week - not by switching outreach tools, but by switching data sources. Prospeo's 7-day refresh cycle and proprietary verification keep your emails landing in inboxes, not spam folders.
No tracking tool saves you from a 35% bounce rate.
FAQ
Is Hunter the same as MailTracker?
No. Hunter is an outreach platform for finding, verifying, and emailing new prospects. MailTracker is a separate Gmail tracking extension that Hunter owns. They solve completely different problems - prospecting vs. open/click visibility.
Does Right Inbox work outside Gmail?
Gmail only - Chrome, Safari, and Firefox browsers. There's no Outlook or Microsoft 365 support. If you need cross-platform email productivity, look at Boomerang or Mixmax instead.
What's a better option for verified contact data?
Prospeo gives you 75 free verified emails per month at 98% accuracy across 300M+ profiles - more generous than Hunter's 50 free credits. It also includes verified mobile numbers, CRM enrichment, and a 7-day data refresh cycle, making it a stronger fit for teams where data quality is the real bottleneck.
Is Hunter better than Right Inbox for outbound sales?
Hunter wins for outbound by default - it finds emails, verifies deliverability, and sends cold sequences. Right Inbox has zero prospecting features. If you're running outbound campaigns, Hunter or a dedicated data platform is the right category entirely.
