OpenedOrNot Pricing, Reviews, Pros & Cons (2026)

OpenedOrNot Review 2026: Pricing, Pros & Cons, and What to Use Instead

If you're looking up OpenedOrNot pricing, reviews, and pros and cons, the situation has changed drastically. 500apps - the parent company behind OpenedOrNot - announced it's winding down its entire suite within 90 days. Most comparison sites still list pricing as "unavailable" or show stale feature tables. The real answer is simpler: it's free, it's sunsetting, and you need a replacement.

Quick version: OpenedOrNot is a free Gmail tracking extension, but 500apps is shutting everything down within ~90 days. The single G2 review (incentivized, from 2022) tells you nothing useful. For a replacement, Mailtrack (free) or Streak (free tier + CRM) are the closest swaps.

What Is OpenedOrNot?

OpenedOrNot is a Chrome extension that tracks Gmail email opens, delivery status, link clicks, and read receipts. It sends real-time notifications when someone opens your email and compiles daily reports showing open timing and activity. It's built by 500apps, which bundled it alongside 50 other business tools in their Infinity Suite. Install it, send emails from Gmail, and tracking happens automatically via an invisible pixel.

500apps Is Shutting Down

This is the only thing that matters for anyone evaluating OpenedOrNot right now.

500apps published what they called "an honest update" confirming the entire suite is being wound down. All products remain live for now. At 60 days, 500agents (their AI successor) opens early access. At 90 days, the 500apps sunset completes, and a final reminder goes out two weeks before services close.

OpenedOrNot Pricing Breakdown

OpenedOrNot's email tracking is completely free - unlimited opens, clicks, and read receipts at $0. The Infinity Suite bundles it with 50 other 500apps tools for $14.99/user/month. But this pricing is moot. You're evaluating a product that won't exist in three months.

Pros and Cons

Pros:

• Completely free, with no feature gates on tracking
• Simple Chrome/Gmail integration that runs invisibly
• Part of a bundled suite if you needed contact management software, helpdesk, and other tools in one subscription

Cons:

• Being shut down within 90 days - full stop
• Apple Mail Privacy Protection artificially inflates open rates, making individual-level tracking unreliable
• One incentivized G2 review from 2022 - zero meaningful social proof
• Capterra users mention integration issues and lag across the 500apps suite
• Tracking pixels increasingly fall under ePrivacy Article 5(3) consent requirements per EDPB Guidelines 2/2023

What Users Actually Say

OpenedOrNot's G2 page shows a perfect 5.0/5 rating. Sounds great until you realize it's based on exactly one review, posted November 2022, with an incentive disclosure. The reviewer called it a "helpful little program" that integrates with Chrome and Gmail so well they forgot it was there. One data point isn't a pattern.

The broader 500apps suite on Capterra paints a more useful picture: 4.4/5 across 25 reviews, with ease of use at 4.3 and customer service at 4.4. Users liked the "all kinds of business apps in one suite" value proposition. The complaints? Integration between apps didn't always work, and the suite lagged because of constant updates. Not catastrophic, but not confidence-inspiring for a tool you'd rely on daily.

Best Alternatives to OpenedOrNot

We've tested most of these, and Gmail tracking tools like Mailtrack, Streak, and Mixmax consistently come up in Reddit's r/EmailProspecting threads. Here's how they compare.

When Data Accuracy Is the Real Problem

Here's the thing: open tracking is the least valuable metric in your email stack. Open rates are inflated by Apple MPP, triggered by bots, and tell you almost nothing about actual engagement. If you're switching tools anyway, ask whether a pixel counter is really what you need. If you're doing outbound, it’s usually smarter to fix email deliverability and list quality first.

Prospeo solves the upstream problem - finding verified emails and direct dials from 300M+ professional profiles at 98% email accuracy. Its 5-step verification process catches spam traps and honeypots before they torch your sender reputation, and data refreshes every 7 days versus the 6-week industry average. Teams using Prospeo book 26% more meetings than those relying on ZoomInfo and 35% more than Apollo users. That's the data that determines whether your outreach lands - not whether someone's mail client auto-loaded a pixel. If you want to go deeper on verification, compare options in our guide to email verification.

Mailtrack

This is the most direct OpenedOrNot replacement. Mailtrack does one thing well: Gmail open and link tracking. The free tier works but adds a small branding signature to your emails. Upgrade to Pro at $4.99/mo to remove branding and unlock link click tracking. If all you want is read receipts without complexity, this is the move. It won't give you sequences or CRM features, but if OpenedOrNot was enough for you, Mailtrack will feel familiar.

Mixmax

Mixmax is what you graduate to when simple tracking isn't enough. The free tier includes email tracking and scheduling. Inbox Copilot at $29/mo adds workflow features on top of tracking, and the full Mixmax Suite runs $89/mo/user on annual billing. It's a proper sales engagement platform - sequences, scheduling, templates, and tracking in one Gmail-native tool. Best for teams who want automation alongside their open tracking. If you’re evaluating similar tools, see our roundup of Mixmax alternatives.

Skip These If You're Budget-Conscious

Streak offers a free tier with tracking plus a lightweight CRM built into Gmail, with paid plans starting at $15/mo/user. GMass dropped its free plan in January 2024; it's $25/mo after a 7-day trial, best for mail merge campaigns. Yesware starts around $15/mo/user and focuses on sales templates and reporting for structured outbound teams. All solid, none free long-term. If you’re building a full outbound stack, start with these free lead generation tools and then layer in paid tools as needed.

Should You Use OpenedOrNot in 2026?

No. The product is shutting down, and even if it weren't, a single incentivized review from 2022 doesn't justify building a workflow around it.

For simple Gmail tracking, grab Mailtrack or Streak's free tier and move on. In our experience, the teams that obsess over open rates are usually ignoring the thing that actually drives replies: reaching the right person with a verified email in the first place. Let's be honest - a 98% open rate means nothing if 40% of your list bounced before anyone saw the message. If bounces are a recurring issue, use this email bounce rate guide to diagnose what’s actually happening.

FAQ

Is OpenedOrNot still available?

500apps is winding down its entire suite within 90 days. OpenedOrNot remains live during the transition but will shut down when the sunset completes. Export your data now by emailing support@500apps.com.

How much does OpenedOrNot cost?

The email tracking extension is free with unlimited tracking. The full 500apps Infinity Suite costs $14.99/user/month. That said, pricing doesn't matter since the entire suite is being discontinued within 90 days.

What's the best free alternative to OpenedOrNot?

Mailtrack offers free Gmail open tracking with branding on sent emails. For verified contact data instead of pixel tracking, Prospeo's free tier includes 75 email credits and 100 Chrome extension credits per month - better for teams focused on reaching the right people rather than counting opens.

Are email open tracking pixels still reliable?

Not really. Apple Mail Privacy Protection pre-loads tracking pixels for all recipients, inflating open rates by 30-50% in many cases. Bot clicks from security filters add further noise. Open rate is now a directional metric at best, not an individual-level signal.
